Expecting everything to continue as is has always seemed so short sighted

Like if Newton was shown a half second video of an apple falling from a tree and decided the apple would maintain speed and pass thru the ground that's not in frame...

I thought most of the scientific community was already on board with multiple big bangs all over, like the Katy Perry song about Fireworks.

When two planes bump up against each other, it causes a "bang" and a resulting universe. Each one with a lifespan. Some may die out quietly, some may overlap with another eventually.

Because of the expansion, there's no way to tell when/if that may happen, no one can see outside their expansion bubble. Any second since our univesers was created we could have been wiped out. And right now is just as likely as 50 billion years ago.
