Hello everyone, My question is: The big bang model proposes that the rate at which the universe is expanding is now decelerating. The inflationary theory proposes that the speed of expansion and separation started out slow and now it is accelerating. But as we know, recently it has been found that the rate at which the universe expands is actually ACCELERATING (dark energy might possibly be the reason for that). Does that mean the big bang theory is wrong? I know the inflationary theory was introduced to modify the big bang theory. Can someone explain this to me? However we should keep in mind that the big bang theory predicted that there are remnant photons from the creation event permeating space (cosmic microwave background radiation), which turned out to be correct. So we cannot say that the big bang is wrong. If someone can support me with a detailed explanation it would be great. Thank you in advance.
