The discussion revolves around the timing of the inflationary period in the early universe, specifically the assertion that inflation begins at approximately 10^-35 seconds after the Big Bang. Participants explore how physicists arrive at this figure and the uncertainties surrounding the inflation theory itself.
Participants generally agree that the timing of inflation is uncertain and that the exact moment is still a matter of debate, with multiple competing views on when inflation began and whether it occurred at all.
Limitations include the lack of compelling evidence for inflation and the dependence of proposed timings on various theoretical models, which may not be universally accepted.
We don't even know for sure that inflation happened. It probably did and it certainly solves some otherwise difficult problems in cosmology, but its occurrence is not known for a fact. How the figure of 10^-35 was arrived at I don't know, and I have seen slightly different figures for both the start and the end of the period, although all agree that it was very brief.Quarlep said:I am a high school student and I was searching the inflation theory.When I searched I found that inflation starts a certain time (10-35) how physicists know that 10-35 is the "true" or"right" time ?
This is basically a guess. Within inflation, it is unclear when inflation started or how long it lasts, as inflation wipes out almost all evidence of anything that came before.Quarlep said:I am a high school student and I was searching the inflation theory.When I searched I found that inflation starts a certain time (10-35) how physicists know that 10-35 is the "true" or"right" time ?
