Hi - Have a question - the basic theory of the big bang is that it began as a singularity. Most explanations talk about a super heated ball of expanding matter. One of the properties of a singularity (from people like Hawkin) is that time ceases to exist. So if there is no time there can be no movement and no movement surely means no heat?
Regards
The idea of the big bang is that everything began in a very small area and expanded from there. This was said to be a singularity, which is no more than a mathematical idea. There is no evidence such a thing can exist.
There is also a slight problem with gravity. Matter forms after 10^-32 of a second and at that point, gravity kicks in and the end of inflation/expansion.
Time is essentially change, but having said that, a singularity if such a thing existed would be ultimately inert and so as you point out, there would be no time. Even inside a black hole, there would be no movement, so as you point out, no heat.

Good to see you back again, Cusa.
Inflation is just something made up to explain the uniformity of the CMB. I don't know why BB-er's are hung up on a singularity. If such a thing existed, it would be ultimately stable. Better to believe that matter and energy appeared over a large area and expanded from that. It would solve a number of problems.

This is 1/4M saying "it can't be so because I don't believe it".
He and Mitch are definitely in the same league.

I've had a look at many of your recent posts and I can see you are just here to insult people instead of joining in debate. You seem to know no science so I suspect you are a little child who uses daddy's computer when he is out and when you go back to school, you boast to the other kids about how you posted on a science forum and that you were smarter than all of them put together.

Debate? With you?
Since your contributions consist of 'I don't believe it, so it isn't so', I'm at a loss as to how to 'debate'. You've stated that the equations of physics mean nothing to you, you don't know any math, you've got only the most simplistic of understanding, and if you don't see it outside your window, it doesn't exist.
My degree in physics is now thirty-five years old, and I haven't worked as a physicist, so I don't claim to be one, but I've forgotten more about physics than you've ever known. And if I'd forgotten nothing, it would still be more than you've ever known.
