Is the Universe made of matter and energy?

The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy’. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.

Where did all the matter and energy in the Universe come from?

In fact, all the matter in the universe could have arisen from a bit of primordial energy weighing no more than a pea. This amazing scenario is a consequence of applying Einstein’s theory of gravity to the inflationary universe model.

What kind of matter in the Universe that has gravity but does not emit light?

dark matter
Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.

What are the theory of the universe?

The prevailing model for the evolution of the universe is the Big Bang theory. The Big Bang model states that the earliest state of the universe was an extremely hot and dense one, and that the universe subsequently expanded and cooled.

Where did the energy come from?

All of our energy comes from the sun, which is our nearest star. The sun sends out huge amounts of energy through its rays every day. We call this energy solar energy or radiant energy. Without the sun, life on earth would not exist, since our planet would be totally frozen.
