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.
What else can I help you with?
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.
Do galaxies emit light?
Yes, galaxies emit light primarily from the stars within them. This light can range from visible light to other forms of electromagnetic radiation such as radio waves, infrared, ultraviolet, and X-rays. The light emitted by galaxies allows astronomers to study their composition, age, and distance from Earth.
What type of electromagnetic radiation of GALEX?
GALEX detects ultraviolet (UV) radiation from celestial objects in space. It is specifically designed to study the UV emission from stars, galaxies, and other astronomical sources.
What is heavenly radiation?
Heavenly radiation is a term used to describe various forms of radiation originating from sources outside the Earth, such as cosmic rays, gamma rays, and X-rays. These types of radiation can come from celestial bodies like stars and galaxies and can impact our planet's atmosphere and surface.

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 else is space filled with apart from galaxies?
Space is also filled with radiation, magnetic fields and high energy particles.
Do galaxies emit light?
Yes, galaxies emit light primarily from the stars within them. This light can range from visible light to other forms of electromagnetic radiation such as radio waves, infrared, ultraviolet, and X-rays. The light emitted by galaxies allows astronomers to study their composition, age, and distance from Earth.

GALEX detects ultraviolet (UV) radiation from celestial objects in space. It is specifically designed to study the UV emission from stars, galaxies, and other astronomical sources.
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 is heavenly radiation?
Heavenly radiation is a term used to describe various forms of radiation originating from sources outside the Earth, such as cosmic rays, gamma rays, and X-rays. These types of radiation can come from celestial bodies like stars and galaxies and can impact our planet's atmosphere and surface.
What do we call objects that emit light in space?
Stars, quasars, clusters, nebulae, galaxies, superclusters, the CMBR (Cosmic Microwave Background Radiation).
What do telescopes do with electromagnetic radiation?
Telescopes collect and focus electromagnetic radiation, such as visible light or radio waves, to create images of objects in space. Different telescopes are designed to detect specific wavelengths of radiation to study various astronomical phenomena, from stars and planets to galaxies and black holes.
What does the uniformity of cosmic radiation imply about its source?
The uniformity of cosmic radiation suggests that it originates from sources that are distributed evenly throughout the universe. This could point to sources such as distant galaxies, black holes, or other cosmic phenomena that emit radiation in all directions with similar intensity.
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.
