    Expansion State Term
Click For Summary
SUMMARY

The discussion centers on the concept of the end state of the universe following a Big Bang, specifically identifying the term "heat death" as the proposed state where all elemental particles are so distant from one another that no interactions occur. This state represents a cold, immobile condition where the universe reaches maximum entropy. The participants confirm that "heat death" accurately describes this hypothetical scenario.

PREREQUISITES
  • Understanding of cosmology and the Big Bang theory
  • Familiarity with the concept of entropy in thermodynamics
  • Knowledge of particle physics and elemental particles
  • Basic comprehension of universal expansion and its implications
NEXT STEPS
  • Research the implications of heat death on cosmic evolution
  • Explore the principles of entropy and thermodynamics in detail
  • Study the Big Bang theory and its aftermath in cosmological models
  • Investigate alternative theories to heat death, such as the Big Crunch or Big Rip
USEFUL FOR

Astronomers, physicists, students of cosmology, and anyone interested in the ultimate fate of the universe.

TL;DR
Do physicists have a name for the opposite of a singularity?
Whereas a singularity is everything together, is there a name for a proposed end state after a Big Bang or something similar? Is there a name for that situation (hypothetical or not) where each elemental particle is so far from every other elemental particle that nothing affects anything anymore, and we have a cold, dead, immobile (?) state?

Thanks.

Thank you both. That is exactly what I was looking for.
