if hot mass exploded per Big Bang theory ,what made it cool off into lumps in the Universe?

Answer 1

Since the theoretical temperature of a vaccuum is what is known as absolute zero, or 0° Kelvin, -273° Celisius, and -459° Farenheit, all it takes is to separate small chunks of matter from other chunks of matter and give them enough time and they will all cool down to absolute zero.

However, one of the key components to the Big Bang theory is that not everything cooled off into small lumps, but into larger lumps.

Larger lumps like the size of planets like the earth and the moon, have cores that are much warmer than the vacuum of space, due to the frictional forces associated with gravity, and the decay of radioactive heavy metals, and other forces.

And even larger lumps collect into nuclear reaction capable quantities of mass like stars.

So, it's kind of hard to say that the Big Bang really did all that much cooling off at all.

Answer 2

The big bang was not an explosion of matter. The name sucks. It started as radiation and as the universe expanded, the wavelength of the radiation stretched to a longer wavelength and got cool. Eventually matter was formed from the radiation energy.

Answer 3

time and the temperature space. i'm not trying to push any buttons here, but people who support the Big Bang theory should think about this. In all the time recorded by humans, explosion and spontanious combustions have DESTROYED and harmed many things. Whether its chemical, or geographical, explosions never put anything INTO order, its always disorder and chaos. So why would one special explosion put everything into order, thus creating the earth and life itself. And if you believe this, why hasn't it happened again/since. Just something to think about.
