According to the Big Bang theory, the the Universe started off as a compact region filled with a uniform glow from the extremely hot hydrogen plasma. As the universe expanded, the plasma and the radiation became cooler. Eventtually, it had cooled enough to allow stable atoms to form and these could no longer absorb the thermal radiation. The universe therefore became transparent instead of being an opaque fog.
Due to the subsequent expansion of the universe, the photons which set off at that time have been red shifted from their original frequency to radiation in the microwave region of the spectrum (approx 160 GHz).

The big bang produced an imprint of leftover heat called?
"Cosmic microwave background radiation", or CMB
From the cosmic background radiation scientists can infer that just after the big bang the universe must have been?

Is tv interference really the sound of the big bang?
About 1% of the static seen on an untuned TV is due to cosmic background radiation, the radiation left over from an early stage in the creation of the universe or Big Bang. As Bill Bryson said. "The next time you complain that there is nothing on (TV), remember that you can always watch the birth of the universe." --------------------------------- TV interference is not due to the sound of Big Bang, but due to some kinds of noises present in the atmosphere leading to the weakening of signal.
The big bang theory of the formation and expansion of the universe is supported by the observed?
There are several astronomical observations which support the Big Bang theory. First of all, the universe is expanding. That can be measured by observation of the Doppler shift in radiation emitted by various stars, galaxies, quasars, etc. Furthermore, the more distant any given astronomical object is, the more rapidly it is receding from us. This is consistent with the expected result of the Big Bang. Secondly, we have observed what is known as the cosmic background microwave radiation. The sky is filled with radiation, no matter in what direction you look, and it corresponds to the radiation that would be emitted by an object at a temperature of about 4 Kelvins. This is also consistent with the expected residue of the Big Bang, 13.8 billion years later (the universe has cooled off a lot, in that time). It is also possible to assess the chemical constituents of the universe, the quantities of hydrogen, helium, and other elements, which can be observed by spectrographic analysis, and again, the results are consistent with the Big Bang theory. Everything fits.
What was the cosmic egg made out of?
The concept of the "cosmic egg" was a vague musing referring to the pre-explosion state of the universe before the Big Bang. The concept was never really thought-out in detail. Our "more modern" imagining of the Big Bang suggests that there was nothing - not even the universe itself - "before" the Big Bang, and that the very notion of "before" may not have any meaning, because the Big Bang is thought to have created time and space itself. So, no cosmic egg. Which means that it wasn't "made out of" anything at all.
Which theory is supported by the evidence of cosmic microwave backround radiation?
The evidence of cosmic microwave background radiation supports the Big Bang theory.
What caused the cosmic radiation background?
The big bang caused the background radiation.
How does cosmic backround radiation differ from the big bang?
Cosmic microwave background radiation was predicted by Big Bang Cosmology about 16 years before the former was discovered -- by accident. The existence, isotropy, and spectrum of CMBR are all exactly as predicted by BBC, and all alternatives to BBC are reduced to stating, "It's just there and there is absolutely no explanation for it."
What is this cosmic background radiation?
radiationsThe big bang
What theory predicted the cosmic background radiation?
The Big Bang.
Why was cosmic background radiation an important discovery?
It is important evidence of the Big Bang.
What leftover thearmal energy from the big bang?
Microwave (Cosmic background radiation).
Which of these is evidence that supports the big bang theory?
cosmic microwave background radiation
What is an observable remnant of the big bang?
well one thing that we can observe from the big bang is its cosmic background radiation
What is the leftover thermal energy from the big bang?
The radiation left over from the big bang is found in the microwave region of the electromagnetic spectrum. As the universe expanded and cooled, the intense hard gamma radiation that existed became radio waves in the low gigahertz region, characteristic of a temperature around 30 Kelvin.
How ia cosmic background radiation related to the big bang theory?
The cosmic background radiation is believed to be the remains of the radiation emitted by the Universe when it started to get transparent - when it had cooled down to a temperature of about 3000 kelvin.
One of the observable remnants of the Big Bang is?
cosmic background radiation :) This phenomenon can be picked up by an ordinary radio or tv. If your radio is not tuned into a station, then some of the the noise (interference) you hear is the cosmic background radiation caused by the Big Bang.
