Now, I understand that any discussion of the very early Universe is entirely hypothetical and to say it is extremely speculative is being generous. However, there are a few concepts regarding the Grand Unified Epoch, the Inflationary Epoch, and the Electroweak Epoch that I am hoping someone will have the patience to explain…
According to http://en.wikipedia.org/wiki/Inflation_(28cosmology)
My question is this: If, “during the period of supercooled expansion during the Inflationary Epoch the temperature dropped from 10^27K down to 10^22K, and when inflation ends the temperature RETURNS to the pre-inflationary temperature in the process called reheating...”
Does mean that, at the beginning of the next epoch – the Electroweak Epoch – the temperature ROSE BACK TO 10^27K (the temperature at the start of Inflation)? If that is correct, then what would the temperature have been at the END of the Electroweak Epoch?
Thanks in advance for your time and consideration,
Stan
According to http://en.wikipedia.org/wiki/Inflation_(28cosmology)
“Reheating”
“Inflation is a period of supercooled expansion, when the temperature drops by a factor of 100,000 or so. (The exact drop is model dependent, but in the first models it was typically from 10^27K down to 10^22K.) This relatively low temperature is maintained during the inflationary phase. When inflation ends the temperature returns to the pre-inflationary temperature; this is called reheating or thermalization because the large potential energy of the inflaton field decays into particles and fills the Universe with Standard Model particles, including electromagnetic radiation, starting the radiation dominated phase of the Universe.”
