When cosmic dust blocks sunlight, it scatters light in all directions, reducing the light reaching the surface and causing temperatures to drop; the solution is to spread the dust cloud rather than compress it, creating gaps for light to pass through. Conversely, when exposed to excessive solar energy, organisms can survive by reflecting more light and absorbing less, achieved by changing angles and tilting to reduce direct light exposure.

The Cosmic Dust Crisis! | #aumsum #kids #scienceAdded:
Uh, what is that?
>> That looks like dust.
>> So much dust.
It is spreading.
>> Everyone stay alert.
>> Hey, I can barely see.
>> The brightness is dropping fast.
>> The temperature is falling.
It's getting colder.
The sun's light is being blocked.
>> The dust is stopping the light.
>> I am shining, but my light is not reaching you.
>> [music] >> Huh?
>> If this keeps going, we'll freeze.
>> We need to clear this.
>> We can't lose the sun's light.
>> Huh?
>> That is a lot of dust.
AumSum, the sun is disappearing.
>> The light is not reaching us.
>> The dust is scattering the light.
>> Scattering?
>> Tiny particles spread light in all directions.
>> So, less light reaches us?
>> Exactly.
>> Then we just push the dust away.
>> Yes, blow it out.
>> That didn't work.
>> It is too much dust.
>> We cannot remove it forcefully.
>> It's getting darker.
>> We are running out of time.
>> EVERYONE STOP.
WE DON'T need to remove it.
>> [music] >> Then what? Stay in darkness?
>> We create paths for the dust to spread.
>> Paths?
>> If the dust spreads out, light can pass through.
>> So, we don't fight it?
>> We gently push it apart.
>> Spread the cloud instead of compressing it.
>> Exactly.
>> But how?
>> Move slowly. Create gaps.
>> Slow? That's not my style.
>> We have to try.
>> I am GOING FIRST.
>> I am next.
>> [music] >> I am going to punch this dust super hard.
>> Now time for my kung fu moves.
>> Keep going.
>> LIGHT.
>> IT'S COMING BACK.
>> HEY GUYS, I'm back.
>> I can see properly.
>> The brightness is returning.
>> The temperature is rising again.
We're safe.
>> Thank you, genius AumSum.
>> You're welcome. Bye for now.
>> Bye-bye, AumSum.
Something changed.
I feel different.
>> It's too bright.
>> This doesn't feel normal.
The heat is rising fast.
I don't know why this is happening.
>> [music] >> It's burning out here.
>> I can't handle this heat.
>> Temperatures are going out of control.
We're overheating.
>> Everyone stay steady.
>> This is getting worse.
>> We can't survive this.
>> We need to do something.
>> What's happening?
>> The sun is getting too bright.
>> Too much energy.
>> Can you stop it?
>> Not directly.
>> Then we're doomed.
>> We don't stop it.
>> Then what do we do?
>> [music] >> We control how much we receive.
>> How?
>> Light carries energy. The more you absorb, the hotter you get.
>> So, we need less light?
>> Yes. We need to reflect more and absorb less.
>> Reflect? We're not mirrors.
>> You don't need to be perfect [music] mirrors.
Change your angles.
>> Angles?
>> If you [music] tilt and shift your path slightly, less direct light will hit you.
>> So, we reduce the energy we absorb.
>> Exactly.
>> I can't reduce it.
>> Everyone, adjust your angles.
>> This sounds risky.
>> We have [music] to try.
>> It's less intense.
>> It's working.
>> Keep adjusting. [music] Don't go back.
>> [music] >> It's still bright, but manageable.
>> We can handle this now.
>> We found a balance. Even with all that energy, we stayed stable.
I'm still very bright.
>> That's okay.
You didn't stop the energy.
You learned how to live with it.
