What are Dark Matter and Dark Energy?
Introduction:
To start with, Dark Matter is invisible material that permeates the galaxies. It exerts a gravitational influence on the stars causing them to deviate from Newton’s and Kepler’s laws. Dark Matter also affects members of a group of galaxies. The nature and composition of the Dark Matter are unknown. In space there is a lot of totally empty space, the vacuum, which contains energy. This energy is variously called Dark Energy and also may be referred as quintessence, the vacuum energy, and the cosmological constant. Dark Energy drives the recently-observed acceleration of the universe.
However Dark Matter IS NOT the Same as Dark Energy. The universe consists of 23% Dark Matter. Our universe …show more content…
Dark matter is dark, meaning it is not in the form of stars and planets that we can see. Where did dark matter come from? Astronomers have always wondered for ages about the existence of dark matter. The ugly truth is that they aren’t too sure what it is made up of, but they do know that dark matter is up in space. Dark matter is thought to exist as large black rings surrounding galaxies. So the space between stars and planets is not just nothing but is most likely matter of some sort. It is known to be that dark matter is made up of subatomic particles called MACHOs (Massive Compact Halo Objects) and WIMPs (Weakly Interacting Massive Particles). These particles aren’t as big as atoms but they are made of the same material as atoms. Astronomers think that WIMPs are between 10 to 100 times the size of protons and dark matter is full of WIMPs. The first evidence that was found of dark matter was in 1933 when Fritz Zwicky discovered the Coma cluster which is a massive cluster of over 1000 galaxies,
