If the universe is infinite, then the big bang theory can't be correct

Click For Summary
SUMMARY

The discussion centers on the relationship between the infinite nature of the universe and the Big Bang (BB) theory. Participants clarify that the BB theory does not assert the universe began from a black hole-type singularity, but rather describes a singularity where mathematical descriptions fail. The consensus is that the universe's finite or infinite status remains unknown, and if it is infinite now, it was also infinite at the beginning. Previous discussions on this topic have yielded similar conclusions.

PREREQUISITES
  • Understanding of the Big Bang theory and its implications
  • Familiarity with the concept of singularities in physics
  • Basic knowledge of cosmology and the universe's structure
  • Ability to interpret mathematical breakdowns in theoretical physics
NEXT STEPS
  • Research the implications of singularities in modern physics
  • Explore alternative cosmological models beyond the Big Bang theory
  • Investigate the concept of infinity in the context of the universe
  • Study previous forum discussions on cosmology for broader perspectives
USEFUL FOR

Students of cosmology, physicists, and anyone interested in the fundamental questions about the universe's origins and structure.

Is this true? Because if it were infinite, how would it start at a small singularity? I mean it didn't start out at a finite size then grow to infinity right?

The BB theory does not state the universe started at a black hole type singularity. The correct type of singularity is a descriptive of when the maths breaks down and no longer makes sense. We do not know if the universe is finite or infinite. If its infinite now then its infinite in the beginning

Yep, what he said.

Also, lundyjb, this exact question has been posed here before and answered the same way.

Often you can get information you want just by doing a forum search.
