SUMMARY

The discussion centers on the ongoing expansion of the Universe as described by the Big Bang Theory. Participants speculate about potential scenarios when the Universe reaches its limits, including a catastrophic event likened to a "100 car pile up" followed by a subsequent explosion akin to the Big Bang. While theories about colliding universes are mentioned, they lack substantial evidence to support them. The consensus emphasizes that the Universe is not expanding into anything tangible.

PREREQUISITES
  • Understanding of the Big Bang Theory
  • Familiarity with cosmic expansion concepts
  • Knowledge of theoretical physics regarding universe collisions
  • Basic comprehension of cosmological evidence and its limitations
NEXT STEPS
  • Research the implications of cosmic expansion on the fate of the Universe
  • Explore theories surrounding multiverse and colliding universes
  • Study the evidence supporting or refuting the Big Bang Theory
  • Investigate current cosmological models and their predictions for the Universe's future
USEFUL FOR

Astronomers, physicists, cosmologists, and anyone interested in the future of the Universe and theoretical physics.

The Universe is always growing.What will happen when we hit the end?I think everything will smash in everything like a 100 car pile up.And when its all pushed it explodes booom big bang.It happens over and over

What end?

As described by Big Bang Theory, the universe is expanding, but it's not expanding into anything as far as we know.

Of course, there are various speculations about colliding universes, but nothing well supported by the available evidence.
