What If You Traveled to Before The Big Bang? #Space #Time #BigBang #Shorts

[00:00:00]Here's what would happen if you traveled to a time before the Big Bang. Okay, try this. Take the entire universe around 2 trillion galaxies, every star, every planet, every black hole, every speck of dust, and compress it into an extremely hot, dense state where our current laws of physics break down. Now, if you could do this, you'd be looking at something resembling the beginning of our universe. This is where things get weird because according to modern cosmology, the big bang wasn't an explosion igniting from one point in space. It was the rapid expansion of space itself from an extremely hot dense state about 13.8 billion years ago. Physics can only describe the universe back to about 10 to the -43rd power seconds before the big bang. Anything before that, our math equations stop working. But first, if you could somehow rewind the universe, galaxies would rush closer together.

[00:01:02]Stars would vanish and atoms would break apart. Everything around you would heat up into a blinding plasma long before you get to the beginning of time.

[00:01:14]Temperatures and densities would become so extreme that even your atoms couldn't survive. But the hardest part would be finding a point in spaceime to go to. As far as our current models show, space and time, as we understand them, emerged with the early universe. So, you'd need a way to step outside our known spacetime, something physics doesn't currently allow, unless you're he who remains from the Marvel Cinematic Universe. That's why scientists say that the Big Bang happened everywhere at once, not at a center you could travel to. But let's say you had an insanely futuristic, impossible machine that helped you get there anyway. Well, you still might not find empty darkness waiting. You might find nothing describable by current physics. Or if one of the speculative ideas is right, well, you could be looking at a previous universe collapsing into ours, the big bounce of a previous cosmos, or the end of cosmic inflation that created the hot big bang. These are real scientific ideas, but none are confirmed
