we know that big bang, acceleration, everything happens.

Are you talking about that first femptosecond?

Like before the, what happened right there?

Right, exactly.

So this is all related to what we were talking about earlier.

And I think the big bang is deeply misunderstood.

So let's be very careful about what we mean when we say the big bang and what we mean by like a certain time.

So, you know, we know the universe is vast and it's pretty cold and it's pretty dilute.

But when we look back in time by looking out into space and seeing how things looked earlier, we see it was denser.

So the universe is less dense now, it was more dense in the past.

You rewind the clock, what happens?

Things get denser and denser and denser and denser.

And our theories work really, really well predicting things when they get all the way up to a certain temperature or a certain density.

And that's the Planck scale.

That's the Planck temperature.

That's the Big Bang is the expansion of the universe from that Planck scale density, which going earlier, that is another thing from that Planck scale density up till now.

That's the Big Bang.

The Big Bang is widely misunderstood as the universe began as a point in space and it exploded out into existing space.

That's what most people's impression of the Big Bang is.

And that's
