As stars evolve from main sequence to red giant phase, they expand dramatically in size and luminosity, fundamentally altering their planetary systems. The star's increasing luminosity heats distant planets, potentially creating runaway greenhouse effects that strip atmospheres, while the expanding stellar radius can engulf inner planets entirely. Simultaneously, stellar mass loss weakens gravitational grip on outer planets, causing orbital instability and potential ejection. Companion stars like brown dwarfs can further destabilize planetary orbits through gravitational perturbations. This demonstrates how stellar evolution inevitably leads to the destruction or transformation of planetary systems, with only massive outer planets potentially surviving the star's death to become part of a white dwarf system.

6000°C Planet! Evolving A Custom System From Birth To Death Ver 18 #5 Universe SandboxAdded:
Hello everyone and welcome back to another universe sandbox video and welcome to part five and the finale of evolving our latest custom solar system version 18 from birth to death. So if you remember the last video we had our cool little eyeball phase planet for a brief period um once the star warmed up enough but even that has passed now our star it's going to enter its final phase today into the full red giant um era and we're going to see what carnage it causes to our planets here. But one thing I've noticed is since we've made the star larger, it's actually got um less spherical since the thing is getting so huge. Yeah, it's not a perfect sphere anymore, which is uh which is quite interesting. So anyway, let's go ahead and see. That's our current lineup of the planets. So remember the system was completely wrecked. Our Nemesis star that we picked up, this was originally an interstellar traveler that our star picked up and now its orbit is a lot closer than it once was. had an interaction with one of the gas giants that got eventually got ejected. But it meant that Nemesis now it orbit is a lot shorter. So, it is going to be coming and going a lot quicker in our systems final days here.
So, without further ado, everybody, let's start speeding up our simulation.
Let's see how this unfolds. So, remember Nemesis is now Yeah, it's going to be swooping by a lot more frequently, therefore causing more turmoil with the outer objects. So yeah, we can see here blue, the last of the um yeah, the only ice giant remaining. We only have two We only have two gas giants left. Blue and big gas. We don't we lost everything else. All the other ones were ejected over a long period of time. Plus, you got all of the outside dwarf objects which are quite interesting. Then we got our very far object over here, Bonk, which um may be in a good position to survive.
It's as we go into the inner system as well. This was the system of greenhouse world. Literally every single object that once had water, they're all greenhouse objects. Every single one.
Literally is the most biggest array of greenhouse objects we've had in one of these. Pretty much every single object other than this object here, Fitziness, are greenhouse objects. So if we go down here, all of them became Venuses. It's literally the system of Venuses. I mean, every single one of these, look how many thick atmosphered objects there are. It is absolutely wild. You got our insanely hot ones there. It is It's madness.
So there we I think this world here is the only one that potentially is still uh could be warmed up, but it has its really weird um environment at the moment. This was the one I think this was the eyeball object if I remember correctly from last video, but um it's orbit's now been slung even further out.
So, it's a weird position. Let's go ahead and see as it reapproaches the star now. So, I believe it was this object with this weird orbit. Let's see as it flies in again. We can't run the simulation any quicker at the moment.
Okay.
So, here it is. Here it's going to increase with the star temperature as course. Put the vicles on so you can see.
So, it's definitely going to have quite the uh quite the change here as it flies by the start. It's going to obviously receive that temperature. It's going to warm up.
Yeah. I believe this was our eyeball object. Let's see. Is it going to Yeah.
Yeah. So, yeah. This was it was this one. Yeah. And even this one becomes kind of a greenhouse object for a brief period as it's all that water vapor builds up, but just not enough for it to fully go absolutely crazy as it condenses back down to a liquid as the planet gets further from the star again.
So, it's in a very very weird position.
Um, but there you go. So, back to our Centur though. Obviously, that is going to be our star of the day as it needs to get a little bigger now. So, size-wise, I'm going to go for an immediate double here. And now the stars finally going to lose temperature. You can see it's really getting opaque. I'm going to have to change it rotational period, I think, because that's looking a bit ridiculous.
So, also going to increase this. Oh, bounce the bulging back. Oh, weird stuff. But there you go. All righty. I'm going to Yeah, as it gets bigger, it's going to rotate slower, I think. So, the closest objects, they're kind of in danger now. I start slowly ramping up and obviously luminosity is going to start skyrocketing.
The temperature is cooling down finally.
So, there you go. Okay. Again, let's make it bigger.
And now we are really truly in the end of days for these objects here. So, the inner planets here, the crazy Venus is now 5,000. The atmosphere on this, I mean, I think the solar winds are going to just strip this atmosphere technically. I think at this point, I mean, having the temperature that hot, I don't think the atmosphere has got much left to give at this point. 6,000 temperature. That is absolutely ridiculous. I mean, that's what it looks like without the the goggles. And you can see it's just a glowing star itself at this point. I mean of light. This thing is emitting itself.
It's hotter than the star at the moment with that atmosphere. But I mean, can we remove the Does this have a magnetic field? We could technically No, it didn't. No, this one's atmosphere should look at the Earth similarity going up. Really? Not so sure about that. But yeah, the atmosphere on this I think technically we should just wipe it out.
But either way, it's not going to last much longer. Anyway, we can see the closest planet is on a very very close proximity with the star. Now we go.
Yeah, the atmosphere on that is absolutely insane. Look at that in ATM.
That is 20 million ATM buildup. Yeah, I'm not so sure that's quite right. If I remove it, it just will start building itself an atmosphere once more.
It still contains tools, I guess. Yeah, but either way, still going to wipe the atmosphere out after some bit of time, isn't it? I think the inner two especially most of these objects.
No, I think their atmosphere is technically be getting wiped out at this point by the star. There you go. They still build. They still rebuild themselves, but they do lose a bit of temperature either way. But this one still wasn't. Oh dear. Well, how doesn't really matter.
That's going to get a lot bigger. So, we are going to continually make that star larger. While that's all playing out, where is the Nemesis? I want to see that return as well. Let's go ahead and uh speed this body up. This nemesis is going to return and cause more chaos as it returns. Our brown dwarf here.
Where are we? It's currently sitting at 600 years. It's going to sling by as you can see here. Going to cause more chaos with some of the orbits as you can see.
Oh yeah. Swoops round. Definitely have blue there. Could be under a threat of having Nemesis just completely mess it up. Oh, very dangerous indeed. Okay, there you go.
Yeah, things are getting really dangerous here. So, while that's all going again, Alentory, we are we're going to continually buff the size here.
I think the first of the planets is going to be fully engulfed. So, Hort here, we're going to expand the star as Horer makes his approach and that may be the end of that as that is going to go in here, I reckon, at this rate. There you go. Or if not, dangerously close to your star. I mean, that's just going to it's not looking good. And we can have the star pretty much just heated up right now of the expansion. Oh, we've gone too fast. There you go. Just slowly, subtly.
So, somewhere about there. Is that too much? Maybe a little one more. There you go. And that's going to fall in.
Is this Is it on the edge? Oh, that.
How's that for being close? Let's slow this down. See if we can actually catch it. Go into the star here.
That is ridiculously close.
Can we watch it go in right on the edge of death?
It's not much left here as it falls in a little faster. A few more seconds. Go into minutes.
Bit of rotation. Yeah, that's uh There you go. It's about to go in. Oh yeah, literally we see we just paused it right as it's gone in there. There you go. And it is gone.
Well, it's been consumed inside. We got collisions on, right? Yeah, collisions are enabled. What's going on here then?
Is it just going to get consumed or is it going to go? What's going on? There it's gone. Yeah, eaten up. So, it's slightly existed in the star for a little bit, but it's uh it's finished.
So, now finally the hottest planet is the closest planet to the star of our 6,000 monster here. Uh 0.6 AU is not going to be enough to survive this though. That star has got way more coming than that. South Centtory again.
Let's have another dramatic increase going up to 0.19 AU now. There you go.
Also, you know, we're going to start losing a bit of mass here. I'm going to put it down to 1.09 sun. A slight loss of mass which is going to slowly release its grip on the objects a little bit. Oh yeah, there you go.
And of course, just going to continue increase that rotation per just so it's not getting too uh bulgy. There you go.
So, the temperature of the star is severely dropping now. There you go.
Okay.
It's got quite the area to grow before engulfing the next planet there. How we doing over here with um actually one thing we need to do as well is continue increase that luminosity going up to 500 now. So even the far away objects here, they're going to start feeling the heat.
And our last uh the last planet with any kind of somewhat conditions the eyeball object, you know, this one's going to start receiving the temperature even further out. So it may be permanently locked in the greenhouse effect eventually on its next uh approach to the star. Turn the goggles off, you get a way better view of it. There you go.
So, even at this distance, even at it further distance, it is now receiving the temperature. You can see the hat zone is reaching pretty far out. Even Nemesis is start feeling it. So, there you go. Even at this distance, the temperature is now going up. So even at it closest approach, this thing is going to be terminally probably terminally damaged on its next approach round as that that is going to that water vapor atmosphere that's going to build up and I don't think it's really going to it's not going to have enough time to cool down probably too much as it goes away from the star. Is it going to have a little bit? It's losing a bit of it.
It's still going down to the reasonable temperatures. But yeah, the absolute condition change on this thing is ridiculous. I mean look at the stats here. the lifelight field. Are you sure about look how high the Earth similarity is on this a very very this this planet had very good potential but it's just its orbit let it down in the long run.
So there you go. Similarity completely slings around there. Huge deficit as it approaches the star but still in a very weird uh orbit has really really been weird. There's Nemesis flying by causing more chaos as well. We see Blue's orbits been changed here the ice giant. How's Big Gas doing here? 385 there. There you go. Definitely receiving the uh receiving the temperature here.
So there you go. So the only the only planet that's not really had it orbit altered too much pretty much this one.
So there you go. Big gas, but that's got enough mass to survive this star probably. But again, back to the start.
We're going to continue evolution now.
Oh. Oh, it just did something. It unlocked itself. Oh, that's a pain.
Can undo it roughly to where we were actually just by using the undo button up at 1.0. So we were roughly there.
Let's go ahead and save and relock that mass cuz that is I didn't unlock that.
That did it itself. The game's cheating on us a bit there. So, let's go ahead and do it properly now with the mass lock because I want to manually control the mass loss. So, star expanded a bit more, but also I'm going to put it down to 1.05.
So, again, losing a bit of the grip on the planets there, but still the star is expanding. Luminosity, let's go to the thousand now. A nice clean thousand.
So, yeah, we're probably in the red giant kind of phase here. this object.
7,000. Oh gosh. Yeah. Bit too quick for us. Slow it down a bit. There you go.
8,000. How is this thing's atmosphere still going at this point? I mean, I should be manually interfering and just removing that atmosphere, but it's got so many materials built into it. What was the cause? It was all that oxygen, carbon dioxide, water. It was all these guys. All this greenhouse effect there.
Those guys creating that absolutely ridiculous. Look at that temperature.
I do think it stars in the game need to be a little more powerful at wiping away atmospheres because where is it the mass loss then you think at the atmosphere would be getting look at the greenhouse effect that is absolutely insane.
Is it the atmosphere layers? I mean what do this have 1,000 atmosphere layers. I didn't apply that. That did it itself which is crazy.
Maybe if we just put this down to one.
Yeah, that would finally cool it down.
You know that's some that's kind of a representation. and its atmosphere is being lost. So I guess we can manually interfere that way. But even then it's still 1,500.
But you know technically if we want to do it visually all we need to sort of do is this and you can say the atmosphere is wiped out now. Nothing left. It's now just a hot rock. So we have technically we've just completely erased this thing's atmosphere. Turn all this down and it's just a raw wrath of the star that's getting it now rather than the greenhouse effect. So there you go cuz yeah that is is absolutely insane. I guess of a few of these guys. I mean, technically their atmosphere layers would be completely reduced. So, we can literally just we can kind of manually just remove their atmospheres kind of just by doing that effect instead.
Yeah. Yeah. All right. Okay.
Yeah. So, that's probably the closest we can get to kind of raising their atmosphere just by lowering the infrared down.
Yeah. There you go. That's a kind of so all of the inner planets there we can kind of technically have their atmospheres pretend their atmosphere have been erased by solar wind there so you can now see the raw surface underneath there we go after it is relentless it's going to still be uh causing chaos there you go how's the orbits doing in the further out something got ejected in Nemesis's latest pass look you can see so even at this point in the system there's still ejections happening so stuff that's escaping the stars downfall there so that's another object gone bonks orbit It's really strung to hang on. We got Nemesis swinging around again.
Coming in for another attack. Let's see what it does.
There you go. Big Gas's orbit was affected by that. You can see Big Gas's orbit has been changed, but also the star losing mass as well. Slightly releasing its grasp could create Nemesis uh allow Nemesis to come and cause more issues as Nemesis has got a bigger presence the more the star loses mass.
Okay, there you go.
Again, let's continue. So, Rapid evolution. That's what we like.
So, let's continue. The stars really still bulging, isn't it? We just increase our rotational period, but also increase our star size. There you go.
Oh, that's done it again. Ah, that's so annoying.
I didn't tell you to do that game.
That's really, really annoying. So, we were 1.05 lock. Ah, that's a pest.
Right. So, now we can increase it again.
So, I want to make the star go up to maybe 0 0.4. Luminosity go up to 2,000 now. So absolutely rapid. There you go.
Rotation period. Just going to slow that down as well. There you go. And then now I'll lower the mass. I want to go to one sun now. So start losing material. And that may have actually just pulled in.
How close is this planet there? Before I before it lost that mass, I think it would have been okay. But now I've lost the mass. It's orbit's been derailed.
It's a Celibby here.
A world that's been tortured for the entire life of this system. Technically, this planet was never warm. It was always absolutely scorching. It was never lukewarm. It was never cold. This thing formed and it was forever hot. The world it was never cold. Sitting right on the edge of death now as our star is approaching the 0.5 AU mark. There you go. Luminosity of the star. I mean reaching out here. I think even bonk here. Even this maybe starting to perceive temperatures soon here. Oh yeah, the outer dwarf objects sitting on the edge of the zone now.
Yeah, there you go. Let's increase our speed a bit. Even blue here. I think this ice giant, even this is going to start receiving the heat now, especially when it flies by. That's for sure. There you go. Oh, yeah. Going up into the hundreds.
It recedes. There you go.
All righty.
But yeah, right on the edge of death here. Remaining planets here. This one's atmosphere still holding on. But again, I think at this point solar winds would just shred it. So there you go.
Underneath now.
High atmosphere. That's what it looks like underneath. It's still got kind of liquid on it surface. What is that?
Ammonia. Liquid ammonia. Huh. Okay. 200 plus. Yeah. Go. Insane temperatures there. Yeah. Interesting. Still hidden under that atmosphere, but we still have to reduce that atmosphere a bit. There you go. Look at that. All righty.
Where's Nemesis? What's that doing? Oh, there it is. It's just come out again.
Boy, I really think Nemesis could cause some chaos here once the star continues to lose mass. Right. So, okay, they unlocked itself. Look at that. Right.
So, star while we're running our sim here, I'm going to make it lose more mass. So, 0.93 suns radius going up again though. Going up to 0.6. So, that's going to engulf some of the planets here. So, Sal on its final approach. Lumin, let's go to 2500 luminosity. There you go.
So that's finally gone. Another planet erased. It is wiped out. There you go.
Who else is on the kill list? I think Akam here may also be going in here on this final orbit as the star just consumes it. There you go. Another planet gone. We can see that our very eccentric orbit here may be meeting beating its match rushing that close to the star. It may just uh fully completely go in here. There you go. And look at packs. Look at this thing. So the star losing mass that's messed that one's orbit up as well. There you go.
All righty. The stars weird shape also causing some issues there. There you go.
Slightly change it back to.
It's cool. It represents that now.
Right. So, there you go. Ora packs. I think that's gone as well. Yeah, another object had it now. U is it going to survive or is it going to be consumed?
Let's have a bit of run simulation time now because we still need to evolve it, you know. So, Nemesis slinging by causing more damage.
There you go.
The instability is getting a bit insane.
Now you can see one of the orbits is constantly being messed around. Nemesis coming in there causing chaos. Look at the Nemesis just constantly just battering the system out there. Look at all the orbits just not having any luck.
Constantly being barged by Nemesis. Just slinging by. We used to wait thousands of years for Nemesis, but now it's every few hundred years.
So just slinging by, causing more and more chaos. Probably approaching again.
There you go.
constantly derailing the orbits.
Look at that chaos. There you go.
I think Euban may have been extinguished there. Has it gone? Yeah, it may have been destroyed. Slung into the star at some point.
Okay. Very interesting. So again, start going to get bigger. Going up to almost peak size now. Going up to 0.9.
There you go. Luminosity. Let's go to about 300. I guess that's kind of the m I think this is kind of the max our sun would kind of get to. I mean theorized.
Anyway, there's no facts here, but yeah, 3,000 luminosity kind of the peak peak um luminosity for kind of red giants around this kind of mass area. Again, we're going to lose a bit more mass.
It's unlocked itself. Oh, it's a 0.9 suns. A little less slowly losing your grip. There you go. So, bit of the drag may say fittiness here. So, this was the only planet that never had an atmosphere in the inner system. May be able to just about survive this. Mora, the only other surviving inner planet there. Big Gas now the third planet from the star.
There you go.
How far is Big Gas anyway? This one's orbit's definitely been messed up a bit.
There you go. 21 years. Seven. Okay.
Righty. So, there you go. So, pretty much at the end of time here, there's not much else to give. Everything else in Tori 0.8 AU could get a little bigger technically.
We can do it.
Slowly expanding. Temperature's dropping 1 AU. There you go. It'll be 1.07 1.08.
Not much else there. It's pretty much the peak size. I think we'll go for a red giant in this scenario. So, there you go. Look at how bulge he is.
Well, I guess that's one thing we changed now. So, everyone's always said old stars shouldn't be spherical when they're this large in the game. So, yeah, technically we're finally getting something a little different. So, there we are.
That's pretty much This is literally the end of everything now. Oh, another object escape the red giant. There you go. Nemesis.
Oh yeah.
Sings around. Still causing absolute chaos. Oh yeah.
Still coming around. Singing around. Oh my gosh. Blue still managing to hang on.
I'm surprised that I'm I'm shocked that this planet has managed to survive this.
I thought it would have gone a long time ago. So, the fact it's still here, it's doing pretty damn well, I'd say.
Right. Okay. So, I think it's time for the death of our stars. Nemesis slinging around. Look at that. Look at Blue's orbit now. Look at that. Oh. Oh, man.
So, our star now needs to become a white dwarf. So, it's going to lose probably even more mass at this rate as well. I'm going to I'm keen to see how this system evolves with a white dwarf replacing our star. So, there we go. About half mass of sun, 0.5 suns. I think I'm going to plop this hat. So, the final stand of our star.
Not much left. I mean, technically, we could do the um the pulsating thing where it goes up and down. So, technically, we could kind of do this kind of effect where it goes up and down like this, but still losing more mass as well. So, technically losing a little more mass as it this happens.
Ch the size is also changing. So, 0.8 Eight big gas. Look at big gases orbit.
Yeah. Really hanging on in there.
Obviously the radius of the object.
Yeah. So the orbits we can definitely mess around with there. All righty. So lock that then there. And let's go for a quick save in case I break anything doing this. And now I'm going to pop in our white dwarf. So what I need to do here, let's go ahead and replace it.
Good with my good old white dwarf template. It's always useful for this. I may have to change the masses. Plop the white dwarf in then put it straight to about 0.5 masses of some. There you go. Our star is dead and all that is left is the sky.
So yeah. Okay. Let's see how it does. Slow down time. Press play.
And our star is dead. That's all that's left. All the temperature. It's going to cool down forever. Mora survives freezing up with uh Yeah, there you go. It's got water on its surface. That's not going to last long, though. It's just going to completely uh freeze over. Nothing keeping that warm.
Hanging on in there. Big gas.
Going to cool down as well. Blue.
And look. See the star losing its mass.
It's lost its grip on those orbits.
Those orbits can no longer be retained.
So there you go. So even more objects being ejected instantly with the loss of mass. So there you go. Is Nemesis going to survive? Maybe Nemesis just goes back into deep space or is it going to go?
Let's see how Let's see how this plays out.
simulation won't run any faster. Why is that? Is there any particles in here?
Maybe I need to delete some particles.
That's strange. There you go. Control D.
Get rid of any particles. All right. So, speed it up. Oh, we just can't run any quicker. Okay. Well, interesting.
So, objects no longer holding in to see what will Nemesis do now with with Nemesis flying by with that big mass.
Nemesis has got a way bigger presence now since our star has lost a load of mass. Will Nemesis just completely tear these from their orbits potentially?
Let's see. The brown dwarf taken over.
Is it going to derail the orbit? It kind of is affecting it. Oh yeah, big gas could now affect more orbit as well.
Interesting.
So, normally our systems kind of die after our stars died, but you know, in this scenario, Nemesis is still having its effect. So, it could technically cause more chaos. I'm going to remove bonk here cuz I think that's pretty much finished. It's all of the remaining orbits. There's nothing else further out is that's everything. So, this is what's what this is what we're left with. Not sure why the simulation is running so slowly, though. That's really weird.
There's not really anything in here that's uh should be keeping it slow, which is weird.
There you go.
Blue's orbit. Hanging on in there.
Nemesis singing around. Let's see if I can save it and reopen it.
splits two.
Okay, let's uh try and reopen it.
Ah, hasn't appeared straight away. H, this game's always a bit weird doing that, isn't it?
Hasn't doesn't automatically appear in your list once you save. Strange old one that. Right, let's go ahead and reopen it.
No, even with reopening, the game is still running it really slowly. Not sure why. That is strange. There's nothing in here that I think would be lagging it out. So, that's weird. But as we can see, hardly any objects survived. That's all we've got left. Just those guys.
Very, very big loss of objects. Six planets left in Nemesis. That's all we've got. This system used to have so many objects, but they got ejected, destroyed.
Man, has that been an absolute massacre?
And hardly anything remains. And yeah, I think the future's uncertain with a lot of these objects. I think Big Gas may be able to hang on to the star, but I don't think Moira will last forever. I reckon big gas itself may get rid of it or Nemesis will definitely pull it away at some point because it is now stringing very close to Nemesis position.
There you go. Okay.
Yeah, it won't run any quicker. Not sure. That is really weird why it's doing that. But yeah, Nemesis, we can have a quick play of it now. I'm going to move Nemesis back to it sort of position there. See if it has any kind of interaction as it goes around. It's going to slowly just kind of tweak it and go around, isn't it? So again, let's have Nemesis speed up Nemesis orbits ourselves. So for instance, if it gets too close to Moa there, could it just pull it away from the star? You know, it's definitely definitely having some kind of effect. If we just keep Nemesis in this area again, as it keeps going by, it just keep tampering those orbits.
Maybe maybe the white dwarf can hold on to it. But it's always being bent a bit.
Maybe it'll crash into the white dwarf.
Look at that. Imagine if that happened.
That would be interesting.
It's really annoying the sim won't run any quicker because I kind of have to cheat and just speed it up myself which is a bit but I kind of want to see Nemesis because this is the deciding factor here.
So there you go. Yeah. So weird why it won't run any quicker.
So Nemesis again things around Mora.
There you go. But technically it could eventually crash into that white dwarf which would definitely be interesting.
I mean, I kind of want to see what happened just for the the sake of it really.
Big gas have an effect on it as well.
How quick it slings around. Oh, wow.
Okay. So, again, what orbit is that? This one. I'm going to slowly start removing some of this.
Just see if it speeds the sim up at all.
Is any specific reason why the simulation's running so slow? It shouldn't be running this slow cuz there's only few objects in here.
Really, really bizarre. There's no parcels.
How bizarre cuz these are the main three I want to see change. I think everything else is kind of This is even then it won't run quick. That's a really bizarre why the sim won't run any quicker.
There's nothing in here that should be slowing it down. It's so weird. Well, anyway, Nemesis, I'm going to keep putting new rounds. I want to see if it will eventually slink it into the star with enough given time.
Will it eventually pull it away or sling it in? Who knows? Nemesis.
There you go. Still changing the orbits as you can see. Expanding the orbit actually. Look. Yeah. Okay.
Or is that just killed it? Is that a collision course? Was it ridiculously close?
Oh my gosh. Here you go. Try and catch this in the moment.
Okay.
swings around. Look at that. Going right near the white dwarf.
Wow.
Dangerously close to the white dwarf. My gosh. Okay, let's watch it go round again. I mean, it is. We can just barely pull it. It's closest point here. But that's a about there. Look how close that is.
Receiving light from the white dwarf.
Actually, a bit of energy from it. There you go. Even then, it still appears small. That thing's only about the size of Earth. There you go. Sunk straight back out, though. Oh, okay.
So, again, Nemesis. I want to see Nemesis reapproach.
See what happens to round two. Will it eventually be enough to sling it around completely?
Let's keep it going.
Oh, big gas. Sling it around as well.
So, Nemesis again. Pull it right back here again. Now, is it going to bend that orbit enough? Obviously, we are we are kind of cheating thousands of years here for this kind of thing to happen because they have to be in the right place at the right time. But even then, yeah, Nemesis not enough to sling it in.
But, you know, for the fun of it and so we're not sitting here all day. I'm going to manually interfere here. Okay, everybody. Mora is now ridiculously close on its final approach to our white dwarf. So we could estimate that you know within a very long period of time that it eventually gets sent straight into the white dwarf. So bit of fun as well. Bit of fant here you can see its surface is having some weird effects as it's warming up out of the cold. So there you go. The white dwarf of course as we are so close to it giving us a faint light in the sky. So there you go with the goggles off though blinding.
So, here it is. Orbit right on connection point. So, let's go ahead and speed it up and let's see what happens.
And now, I reckon it could get torn to shreds a bit before it actually get approaches. You can see it's being bulged. Look, it's no longer spherical.
It's all It's definitely get Oh dear.
Yeah, look at that. That's a cool effect though of all the gravity's, you know, the that's a strong pull that the white dwarf's putting on this thing. So, you can see here it rotational period's been sped up as well. Look at that. Oh my god. Whoa. Now that is cool. So on approach to the white dwarf, is it going to I mean it should it should this has been simulated to pretty much collide. Yeah. Here you go. Look at the bulge instantly. Just Yeah. The pull of that star. Here it is. As it goes in planet colliding with a white dwarf.
Look at the shape of that. Is it going to go in? O go in.
I think it is going to connect. We're traveling at milliseconds here. It has connected the white dwarf eating up the remains of that. Oh yeah, this is something that could happen after billions of years. Is it going to survive the encounter? Oh my god. Surely not.
No way. No way it survived that. Just a little brush on the surface. Let's see if it comes around again.
How's that going to Whoa.
How's that going to just sort of Oh my gosh. It's orbit's been messed up forever, so or it's rotation, so it's always going to be hot now.
Just a little Oh my gosh, that is wild, though. Wow.
Crazy stuff. Absolutely. Look at the shape of it.
So, just lower the speed of it. Will that just be enough for it to go? I think that'll be enough for it to go in.
Yeah, there you go. Right. Finally, give us our little collision. That's all we want to see.
So again, this is a theoretical future we're assimilating right now as a what if. But here we go.
The drama. Here it is. Is that very oblate shape crashes into our white dwarf. The last of the inner planets finally meets its match. There you go.
It's not getting out of that. And it is gone. The white dwarf has consumed it.
It's a bit of energy. And that's the end of that. And all that remains is big gas and Nemesis. I reckon Nemesis would eventually clear out the outer system.
So yeah, that's kind of what you ended up with. Maybe even Big Gas would eventually be pulled away. But that kind of does it for the end of this system, everybody. So, what do you think of that?
