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.
There is an entire sub-genre in Comics of cartoons riffing on Garfield like this one. Nearly every cartoonist has done it and, oh my lord, it fills me with joy & reminds me why I actually love people.
If I remember correctly Jim Davis has even said he likes and approves of such things. Wasn't there a Garfield minus Garfield book published at some point with his blessing?
