The conversation between human and AI assistant.
How could the universe appear out of nothing and what was before the big bang?
That's fascinating. Do scientists have any evidence to support these theories?
Yes, there is evidence to support the inflationary model, such as the cosmic microwave background radiation that we can observe today. As for the multiverse theory, it is still speculative and not yet supported by observational evidence. However, scientists are actively researching and exploring these ideas.
