hi everyone,
i am not a physicist, so please forgive me and help me to clarify some basic concepts.
in the context of the inflation of the universe, as i understand it, it was the energy density of the void that expanded space-time, so that the energy density remaining (almost) constant coupled with an increase of volume, created a negative pressure and this in turn led to an exponential increase of the volume with the energy density of the void staying (almost) constant until falling into a lower state of energy at the end of inflation.
Is this the reason why during inflation we don't see an exponential decrease of the temperature of the universe? if that is the case, how is the energy density of the void related to the temperature of the universe?
if that is not the case, why didn't the universe cool down in an exponential way during inflation, as all bodies do when they become bigger in volume?
thanks for answering me,
matteo
