If big-bang happened, why aren`t everything scorched?

The Big Bang was neither big nor a bang. It started from a tiny singularity and there was no fluid in existence to carry sound.

That's not quite right - the quark-gluon plasma that formed after about a millionth of a second was very much a fluid - it behaved as a nearly frictionless liquid.

Also, the singularity is just the point where general relativity breaks down, it just means we can't say what there was or what was happening at that point, and a measure of size is only relevant with respect to our observable universe, which is a small part of the whole (the default assumption is that the universe is spatially infinite, and was at the big bang). It was not an expansion of a point in space, but an expansion of all space, which may have been infinitely large. Singularities are points in time, not points in space.

We are indeed scorched, constantly blasted with the cosmic microwave background radiation left over from the Big Bang. But things cooled down long ago and by now the microwave background is only strong enough to heat us up by a minute fraction of a degree Kelvin.

Were it not for our planetary magnetosphere and atmosphere, we'd also be scorched by cosmic rays, gamma rays, and solar wind.

Brilliant! Absolutely brilliant!

You actually thought.

thanks^^

That was the commonest view before the red shift was discovered. It's pretty well dead now. The newer one, with zero evidence is for a pulsating universe which bangs then contracts then bangs and contracts endlessly.

my version of the infinite universe is a question of wether the big bang was the start of our universe, or something more akin to a ripple in a pond, a drop of water hitting a pond, all you would see would be the ripple spreading out, but what if tehre is more universe behind that.

Gotta ask what the evidence is? We have evidence for a big bang. Before that I don't think we have real evidence.

well it's not a evidence argument, just one hypothesis about the nature of it all heh. though I've heard thats one of the theories that scientists have wondered about.

Lotsa theories.

I like your theory, the big bang-theory has flaws I think, ripples in water

I'm curious what you think the flaws are?

Hello, I`ve been thinking a little about it, when everything cooled afte the big-bang, shouldn`t everything look kinda scorched after the explosion to begin With, I find it a little strange, is there any other theory out there than this one?

The Big-Bang wasn't an explosion. It was an expansion of space-time. Then, came stellar nucleosynthesis where every element of the periodic table was made in a star.

When people say there are no stupid questions they are wrong.

The Big band theory might not be perfect, but it makes a lot more sense than the Biblical creation myth.

well, firstly, energy itself has the ability to perform action and give off heat without an start since everything is here already obvisoly, so I kinda doubt a little that it all started with an explosion, I think energy spinned around and around and finally due to sentrifual power it spread into empty and infinite Space, then when energy itself cooled it turned into different matter we see today since all matter is just enegy

You think that based on what? It sounds like a hodgepodge of ideas you pulled out of thin air.

Have you read around the subject?

no, it goes deeper because everything spins, all planets spins, if there really was an explosion, everything wouldn`t spin, it would just go into space in a straight line

It was not an explosion. It was an expansion at every point.

Again, how much academic literature have you read on this subject?

but, you can`t really explain why somethign spins to the right or to the left still, even if planets gets hit with things and start spinning, there must have been a start all the way to the beginning with ether spinning to the right or to the left
