Michio Kaku: The Truth About UFOs, Aliens & Human Immortality

All

right, so my understanding of the Big Bang Theory is that there's a large explosion that then creates all of these galaxies and planets.

What is the Big Bang Theory? How did that happen?

Well, we think about 13 billion years ago, There was this cosmic egg that was unstable, and it exploded.

And out of that explosion came what is called the Big Bang.

And what was in the Big Bang? All the subatomic particles you see in nature.

Out of that came the galaxies, the stars, and so on and so forth.

So the universe was created in a cosmic explosion.

And then the question is, what set off This explosion.

Well, if I knew how we get the Nobel Prize, we don't really know.

But the leading theory, and it says the theory, the leading theory is that it was basically vibrating strings that were unstable and exploded, creating the atoms that we see in nature today.

And of all the particle theories that we've looked at, it is the only one which has survived all challenges.

That doesn't mean it's correct.

It just means it's the only game in town.

Michio, if before the Big Bang happened, was the universe just a big dark space?

First of all, we don't know what happened before the Big Bang.

However, if you take a look at string theory very carefully, It gives you the possibility that there wasn't really an infinitesimal bang at all.

Okay.

That there was another universe similar to our universe that collapsed.

And in the collapse, there was an explosion that gave birth to our universe, and it could pulsate.

We still don't know about this.

There are Nobel Prize winners debating this question.

Maybe the universe pulsates.

It expands, contracts, explodes again, and creates yet another universe.

This is called the multiverse theory, but it's only a theory.
