Why hasn't the radiation left over from the big bang dissipated to the far ends of the universe?
The radiation left over from the big bang, known as the cosmic microwave background radiation, has not dissipated to the far ends of the universe because it is constantly expanding and cooling as the universe expands. This radiation is spread uniformly throughout space, and although it has cooled significantly since the big bang, it can still be detected in all directions.
Cosmic microwave background radiation found uniformly spread throughout the universe is supposed to be what?
Cosmic Microwave Background Radiation is electromagnetic radiation left over from the events of the Big Bang. This radiation causes a very slight increase in the universe's temperature; the coldest areas of the universe will be only about 2 degrees kelvin (2 degrees above absolute zero). It is not spread in a perfectly uniform pattern, though the differences in density are very slight.
Is radiation generated by the big bang cooled and now is detectable as microwaves?
Yes, that is correct. The radiation generated by the Big Bang is called the cosmic microwave background (CMB). As the universe expanded and cooled over billions of years, the high-energy radiation transformed into lower-energy microwaves. Today, the CMB is detected as a faint glow of microwaves that permeates all of space and provides crucial evidence for the Big Bang theory.
What does cmb stand for?
Among other things, it means Cosmic Microwave Background.
What is the relationship between cosmic background and the big bang theory?
It follows logically from what we know about physics that the expansion of the universe from a hot and dense state should produce a remnant of microwave radiation. Reasoning from the Big Bang model (particularly the LCDM model), it is also possible to work out the intensity (temperature) of that radiation, and the nature, size and distribution of variations in that radiation. Detailed observations of the night sky have confirmed these predictions to a remarkable degree.
What momentous event do astronomers think cosmic background radiation is left over from?
The Big Bang
Why hasn't the radiation left over from the big bang dissipated to the far ends of the universe?
The radiation left over from the big bang, known as the cosmic microwave background radiation, has not dissipated to the far ends of the universe because it is constantly expanding and cooling as the universe expands.

What radiation did Arno Penzias and Robert Wilson find in space?
Cosmic background uniform microwave radiation left over from the big bang.
Background radiation detected in space is believed to be evidence that?
the universe underwent a Big Bang, as this radiation is the remnant heat left over from the early stages of the universe. This background radiation, known as the cosmic microwave background, supports the Big Bang theory as it provides a way to study the conditions in the early universe.
What radiation is left over after the big bang and what has happened to it as the universe has expanded?
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 heat left over from the beginning of the universe?
The heat left over from the beginning of the universe is known as the cosmic microwave background radiation. It is a faint glow of radiation that permeates the entire universe and is a remnant of the Big Bang. This radiation provides important clues about the early universe and the formation of galaxies.
How is the age of the Universe determined?
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.
Why is the primordial background radiation visible in all directions?
The cosmic microwave background radiation is visible in all directions because it represents the thermal radiation left over from the Big Bang. As the universe expanded and cooled, this radiation became uniform in all directions, making it observable from any location in the universe.
What is cmbr?
CMBR stands for Cosmic Microwave Background Radiation, which is the residual radiation left over from the Big Bang. It is the oldest light in the universe, providing valuable insights into the early universe's conditions and evolution.
Why hasn't anyone heard the Big Bang?
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.

What type of radiation does the universe emit the most?
The universe emits the most cosmic microwave background radiation, which is thermal radiation left over from the Big Bang. This radiation is spread uniformly in all directions throughout space and has a temperature of about 2.7 Kelvin.
