Since the collapse would happen only at the speed of light, and the universe is so vast, it could have been happening for millions of years by now and the human race could still die by natural extinction before it gets anywhere near us. If the collapse originates from beyond the observable universe, it’d never reach us.

The neat thing is the collapse travels at the speed of light, so nobody will ever know what hit them.

Garfield, did you move a small region of the universe to a true vacuum state?
