2019-03-28: Could the Universe End by Tearing Apart Every Atom?
- 07:02: ... from us to the nearest inaccessible region of space is called the 'cosmic event horizon'. Now, if the expansion is accelerating, then, over time the distance ...
- 07:38: But as long as we have a nice gravitationally bound galaxy to live in, the cosmic event horizon can never shrink to a size smaller than that galaxy.
- 07:47: ... by the increasing dark energy there's no protection from the encroaching cosmic event horizon. ...
- 08:10: That is the big room scenario, It happens when the cosmic event horizon is smaller than the smallest possible structure.
- 09:26: ... this doesn't mean that the cosmic event horizon is quite inside the Milky Way just yet, just that the effect of phantom ...
- 09:38: In fact, at this point the cosmic event horizon is still about 200 million light years away.

- 03:23: We can ever get to anything beyond the cosmic event horizon because that space will be moving away from us faster than light before we reach it.
- 03:37: Given our best measurements of cosmological parameters, we think that the cosmic event horizon is around 16 billion light years away.
