Atheists are keen to ask 'If God exists then who made Him'. Why can't they explain what happened prior to the 'Big Bang'? Surely whats sauce for the goose is sause for the gander.
If God exists, how did God come about? If the Big Bang happened, how did it come about? These are both valid questions.
The big difference is that God is necessarily complex, but the Big Bang seems to imply a singularity. Therefore God must have a complex reason for it's existence, but no such complexity is required for a perfect, simple point of extreme energy.
Easy: because science doesn't claim to know EVERYTHING yet. It freely admits that there are still things to find out, what happened before 10[sup]-42[/sup] of a second after the Big Bang is one of those things science is still trying to work out. Years (decades) ago that figure was much larger, the gaps in our knowledge also much larger: we'll get there (with luck and hard work).
Relative to what? Please Register or Log in to view the hidden image! We can still pick up the residual "heat" nowadays, at a temperature of about 4 Kelvin (that's four degrees above absolute zero) spread evenly throughout the entire universe. So to be "only" that cold after 15 billion years and spread all over like that it must have been pretty hot to start with. http://csep10.phys.utk.edu/astr162/lect/cosmology/hotbb.html
By forming everything that there is now - the heat that was there is shared out amongst everything. The energy from that heat is still in the particles that exist, and the forces that bind them, and gravity etc.
Whoever or whatever existed before the so-called 'Big Bang' took place must have been pretty bored with it's existence, otherwise all of us wouldn't be here now talking about it.
so it was super super hot, then it snuffed itself out? How quickly did it burn up the oxygen and snuff itself out?
The last theory I heard was that there were several Big Bangs. Wow man! what a firework display that was!
There is no room on this forum for gods and atheism discussions. Although in this case, you're using it for comparisons sake to a legitimate question. Please don't further the discussion of gods and atheism. Science is still in its infancy, hence hasn't answered every question in the universe, despite the demand for answers.
There wasn't any oxygen - that was formed much much later. Heat is a measure of energy, rather than something burning. It didn't snuff out - the heat caused "reactions" , which formed particles and matter. As the temperature dropped then things became more stable, particles, atoms, molecules, compounds formed.
It didn't burn, as Oli says, but it's still in the process of cooling. You aren't at absolute zero yet, are you? No. Then there is still residual heat in the universe.
