  • 01:22: To review: the particle horizon defines the limit of the visible past, and there’s also cosmic event horizon defining the limit of the visible future.

  • 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 ...
  • 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 ...
  • 08:10: That is the big room scenario, It happens when the cosmic event horizon is smaller than the smallest possible structure.
