It has.
Cosmic microwave background radiation. See related link for more information.
The cosmic background radiation refers to the faint radiation left over from the early stages of the universe, which was discovered and studied in the 1960s. It is considered a major piece of evidence supporting the Big Bang theory. This radiation is consistent with predictions made by the Big Bang theory and provides strong evidence that the universe was once in a highly dense and hot state.
the weakness of cosmic back ground radiation as those radiation are left over of big bangs
Arno Penzias and Robert Wilson, two radio astronomers, accidentally discovered evidence of the Big Bang Theory in 1965. They detected a faint background radiation uniformly spread throughout the universe, known as the cosmic microwave background radiation. This discovery provided strong evidence for the Big Bang Theory and was later awarded the Nobel Prize in Physics.

Cosmic background uniform microwave radiation left over from the big bang.
nothing happened to that radiation that still expanding one or another day it will explodes that radiation is one ane only has the velocity that equal to light that is gamma radiation

The age of the universe is determined by CMBR, which is left over energy from the Big Bang Theory. CMBR stands for Cosmic Microwave Background Radiation.
A theory that states that the universe began with a tremendous explosion.
They have. We can still detect microwave radiation left over from the Big Bang. While there is no actual "sound" from it anymore, since most of space is devoid of any medium with which to carry sound, we can still "hear" it with scientific instruments.
Researchers found the "cosmic microwave background radiation", which is a heat imprint left over from the big bang. The redshift of light emitted by most galaxies indicates the universe is expanding.
Penzias and Wilson were awarded a Noble Prize for discovering the cosmic background radiation, the left-over 'glow' of the universe from the Big Bang Theory. This is a very weak microwave radiation. In the early part of the last century, Edwin Hubble discovered the expansion of the universe. Discussions and speculation of many scientists on the topic of expansion, (Is it expanding? What is it expanding away from? What is it expanding into? How long has this expansion been going on? What caused the expansion? and more) led to the development of the Big Bang Theory. Steven Hawking (sp?) has been investigating this kind of question for 40 years or so.
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.
