This is a difficult question to answer, like many things in science. We know they exist, but we wonder why.
Gravity exists, we roughly know how it works and its effects, why it exists? It just does. It happened to be a part of the laws of physics put into motion once the universe formed.
Radiation as it is commonly thought of, for example alpha radiation, is given off by the decay of certain elements. Radon gas is radioactive, thus it decays slowly to a more stable state and in doing so it releases charged particles - alpha.
We know things happen, we know how they happen and can predict when.
What we really will never know (probably) is why.

How does electromagnetic radiation from distant galaxies support the big bang theory?
Given by the fact that electromegnetic energy cannot be seen and how the radiation from distant galaxies supports the big bang theory? it can easily be said that...I dont know the answer. (0_0)
Quasars are high-energy galaxies.?
More precisely, quasars are high-energy galaxy CORES, compact enough to appear starlike, yet emitting more radiation than a million "ordinary" galaxies.
Why did the discovery of cosmic background radiation with a wavelength of 7.35 cm help to support the big bang theory of the universe?
The radiation was 100 times more than expected and they were certain it did not come from our galaxy. They reasoned that the Big Bang had released a tremendous blast of radiation and scattered the matter that condensed into galaxies.
How time is affected between the galaxies as there is no mass there?
In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.
What are three forms of evedence used to support th big bang theory?
Three important pieces of evidence are:* The redshift of distant galaxies. This means that galaxies are moving away from us. * The percentages of elements and isotopes. This closely matches predictions from theory. * The cosmic background radiation. This, too, closely matches predictions from theory.

What do active galaxies differ from normal galaxies?
Galaxies that emit much more radiation (different types of radiation) than a typical galaxy. This actually happens in the galaxy's center, so it's more accurate to talk about an active galactic nucleus. The active galactic nucleus is believed to be caused by a black hole. From Wikipedia: " The radiation from AGN is believed to be a result of accretion of mass by a supermassive black hole at the centre of its host galaxy."
Quasars are high-energy galaxies.?
More precisely, quasars are high-energy galaxy CORES, compact enough to appear starlike, yet emitting more radiation than a million "ordinary" galaxies.
What did the discovery of background radiation distributed evenly throughout the universe provide support for?
either starlight spectra or moving galaxies.
What else is space filled with apart from galaxies?
Space is also filled with radiation, magnetic fields and high energy particles.
How do cosmic background radiation the chemical composition of the universe redshift of light and movement of galaxies support the theory of the Big Bang?
Redshift: The only reasonable explanation for the redshift is that most galaxies are moving away from us.As for the cosmic background radiation and the chemical composition, both of these closely match what is expected from the models about the Big Bang.
What do we call objects that emit light in space?
Stars, quasars, clusters, nebulae, galaxies, superclusters, the CMBR (Cosmic Microwave Background Radiation).
What electromagnetic waves are produced by stars and galaxies?
Since all such emissions are "black body radiation" (or pretty close), the correct answer is "light". All wavelengths... from the longest radio waves, to very energetic gamma radiation.

The radiation was 100 times more than expected and they were certain it did not come from our galaxy. They reasoned that the Big Bang had released a tremendous blast of radiation and scattered the matter that condensed into galaxies.
Who found the galaxies?
who discovered the galaxies who discovered the galaxies
What are the types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
What galaxies are sometimes called dwarf galaxies being typically smaller than spiral galaxies?
Elliptical galaxies are sometime called dwarf galaxies.
