(I am not a physicist - so, please be gentle ) I was watching a program last night on the SCI channel, Did the Big Bang Really Happen? and they were describing the 'Singularity' as being this super hot very dense and infinitely small thing. And then when it went through the 'inflation' and became trillions of degrees hot. If I remember what happens to gases (which I know is not like the 'singularity') when a gas is compressed it heats up and when it is decompressed it cools. Why would the singularity be of any temperature if it was essentially a nothing and why would it become super heated during the 'inflation' period?
