Description

‘Eternity’—time that goes on and on and does not end—used to be the province of philosophy, even theology, with no real evidence. But now cosmologists are using astounding observations and new fundamental theories to project what will happen to our universe in 10^100 years – that’s a number with one hundred zeros. And then there’s other possible universes too.

We are at a point when science reaches a point of becoming philosophy again

We don’t know we theorise we’ll never know

I think what bothers us about the past is how our vantage point seems skewed. With what seems like eternity to the future ahead, and only 14.8 behind we forget or assume that is all there is, but in reality, it could only mean we are just closer to the end of but one of many epochs that our universe has undergone, and each transition to a new epoch places a barrier of physically opaque transition that is impossible to see beyond into the past. It does not mean there isn't more beyond it, only that there was a transition before that point.

Huge fan of Dr. Carroll and how he views nature and how it works on a fundamental level.

In another video in this series, Sean Carroll said that, in his opinion, the universe is a single wave function. If that’s true (and it is), it’s ONE thing and is by definition incomparable and therefore without dimension. And since it is one, it has nothing to travel through and there is nothing to travel through it, so no time.
