Question

Where does radiation in the universe come from?

A) All objects radiate some form of energy
B) Any objects in the universe with a temperature above absolute zero
C) Only stars and other large bodies (i.e. planets, asteroids)
D) Only black holes and other gravitational vacuums

Answer 1

I would say the answer is B, any objects in the universe with a temperature above absolute zero.

Answer 2

The correct answer is option B, Any objects in the universe with a temperature above absolute zero

Step-by-step explanation:

The radiation in the space is mainly made up of electrons which have been extracted from the atoms. This ionization of matter in space takes place due to high speed of rotation of atoms (usually atoms move at the speed of light) leaving behind the nucleus of atom. Thus any object in space that move at this high speed gets ionized and thus emits radiation. Therefore, the objects which are at temperature above absolute zero means that they are not frozen and thus they can move therefore all such objects above absolute zero temperature in the space moving with speed of light emits radiation
