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

In summary, the BB theory does not suggest that the universe started at a black hole type singularity, but rather describes a point where mathematical equations break down and no longer make sense. It is unknown whether the universe is finite or infinite, but if it is infinite now, it would have been infinite at the beginning as well. This question has been previously answered on the forum and it is recommended to search for information before asking a question.

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.
 

What evidence supports the big bang theory?

The big bang theory is supported by multiple lines of evidence, including the cosmic microwave background radiation, the abundance of light elements, and the expansion of the universe. These observations all point to a beginning of the universe in a hot, dense state.

How does the infinite universe concept challenge the big bang theory?

The idea of an infinite universe challenges the big bang theory because it suggests that the universe has always existed in an unchanging state, rather than having a specific beginning point. This goes against the central idea of the big bang theory, which proposes that the universe began in a highly compressed state and has been expanding ever since.

Is the big bang theory completely disproven if the universe is infinite?

No, the big bang theory is not completely disproven if the universe is infinite. While an infinite universe may challenge some aspects of the theory, it is still supported by a vast amount of evidence and remains the most widely accepted explanation for the origin of the universe.

Can the big bang theory and an infinite universe coexist?

Yes, it is possible for the big bang theory and an infinite universe to coexist. In fact, many scientists theorize that the big bang itself may have occurred within an infinitely expanding universe, rather than creating the universe from nothing. This concept is known as the "inflationary model" of the universe.

What further research is needed to better understand the relationship between the big bang theory and an infinite universe?

Further research is needed to explore the concept of an infinite universe and its implications for the big bang theory. This could include studying the expansion rate of the universe, the distribution of matter and energy, and the potential existence of other universes beyond our own.
