What does the original flash of the big bang appear as?

Answer 1

The big bang could not have looked like anything, because it would have been impossible to view it from the outside. Just read all of this stuff: ****** It seems confusing that the Big Bang could have happened even though there was no matter or energy in the universe. But really, scientists speculate that there could have been a time before matter, energy, and time itself even existed. The "Big Bang" is a term that describes the event that created the universe. It goes like this: There was no time, no energy, and no matter. basicly, NOTHING existed. Then, a tiny volume of space, smaller then the head of a pin, suddenly expanded and grew to an enormous size. As the volume of space expanded, it created all the energy and matter in the universe. It created nebulas and galaxies of stars and planets. (and many other things, of coarse.) This is when time began to flow. There is plenty of evidence to support that this theory is true. The big bang would have been such a huge event that the waves of energy it created are still traveling in space today! People have actually detected these waves with a device called a spectroscope. Not only this, but scientist think that the universe is still expanding. basicly, the Big Bang is still happening today. We know this because astronomers have noticed that the galaxies of our universe are all moving away from eachother. They are all moving away from the centre of the universe, where the big bang started. The universe is still getting bigger to this day.

Answer 2

The original flash of the big bang is thought to have appeared as intense radiation filling the universe. This radiation eventually cooled and stretched to become the cosmic microwave background radiation that we observe today.

Answer 3

No one knows and humans with the equations can not predict either as the rules of nature and space-time never existed before the Big Bang. The common misconception is that there is a large explosion in space. As far as we know, space or for that matter, nothing actually existed before the Big Bang that has effected the universe which exists now. We are not totally certain about what the Big Bang looked like. There was definitely light though.

Answer 4

There is a very faint background radiation which appears to be coming equally from all directions in space. So-called "black-body" radiation is measured in the frequency of the energy, and is calibrated in the temperature of the "black body" that would radiate at that frequency.

The temperature of the microwave radiation is 4 degrees Kelvin. Physicists had calculated that if the universe was born in a "big bang", then there ought to be a sort of an "echo" of blackbody radiation coming equally from every direction, and that the temperature of the radiation would be an indication of when the universe was born. Arno Pezias and Robert Wilson were physicists working for Bell Labs in 1964, trying to design a microwave antenna to minimize stray noise in their microwave transmission systems. But there was a very low-level source of noise that they were unable to identify; it seemed to be coming from every direction equally. You can read at the links below how they figured it out, but Pezias and Wilson shared the Nobel Prize in Physics for determining that their stray radiation may be the background echoes of the Big Bang.
