What momentous event do astronomers think “cosmic background radiation” is left over from?

Answer 1

Big Bang is the correct answer for the KILT radio trivia.

Answer 2

While the most common answer will be 'the Big Bang', the background radiation was actually the radiation left over from the 'recombination era'. This happened when the universe cooled enough so that the matter was no longer opaque and so let light through. The current estimate is that this occurred about 500,000 years after the Big Bang.

Answer 3

What in the heck is going on here -- this precise question has been asked about 50 times today!

The Cosmic Background Radiation is believed to be the remnants of the Big Bang.

Answer 4

What momentous event do astronomers think “cosmic background radiation” is left over from?

BIG BANG is the us99 trivia answer.

Answer 5

Answer 6

Big Bang

Answer 7

Big Bang
--------------
According to Krauss, since Edwin Hubble advanced his expanding universe observations in 1929, the "pillars of the modern Big Bang" have been built on measurements of the cosmic microwave background radiation from the afterglow of the early universe formation, movement of galaxies away from the Local Group and evidence of the abundance of elements produced in the primordial universe, as well as theoretical inferences based on Einstein's General Relativity Theory.

Answer 8

Father Georges-Henri Lemaître was a Belgian Roman Catholic priest, honorary prelate, professor of physics and astronomer.

Monsignor Lemaître proposed what became known as the Big Bang theory of the origin of the Universe, although he called it his 'hypothesis of the primeval atom'. He based his theory on the laws of relativity set forth by Einstein, among others, although at the time Einstein believed in an eternal universe...

Dr. Fred Hoyle actually coined the term Big Bang, as a joking reference to the "other theory" as Hoyle had his own Einsteinian theory of steady state that went down to defeat when Bell Labs found those Comic Background radiation readings in the 1960s while noting a 3 degree Keliv level no matter where they pointed a special radio telelscope.

As to what cause the Gamma Rays, it's a bi-product of what is believed to be fusion when the primordial atom compacted too intensely and atoms began to fuse together within the singularlity.

Gamma Rays are also found around black holes

Gamma rays also get released when positrons collide with electrons

So inside the singularity, the primordial atom, atoms were fusing together and possibly matter and anti matter were colliding together and gamma rays began to be emitted and as the fusion amplfied the singularity followed the laws of physics and expanded outward expelling elementary particles and rudimentary matter and possibly chuncks of the primordial atom material (black hole stuff)

The first things out and fastest moving would be the Gamma Radation followed by the slower more complex matter (eletrons, protons, neutrons, positrons, etc) and eventually photons of light were generated.

Answer 9

It's left over from the Big Bang- or so they say.

Answer 10

The Big Bang works for the radio trivia:-)
