The Theory Of Dark Matter

Good Essays

Introduction-
Earth can be seen as a grain of sand on the beach once we compare it to the whole universe. The question is what possible could occupy the majority of the universe, just within the Solar System we can see that the planets are orbiting around the Sun. We can determine where the planets are by calculating how fast the planet moves and where it is at in a certain time. So if the planet isn’t where you calculated it to be at what are the causes? One possibility is that we still don’t fully understand all laws of gravity or there is extra mass within the Solar System that is causing the planets to alter their trajectory. This lead scientists to believe in the existence of dark matter and so began investigations and experiments to learn whether it actually existed or not (Start with a bang, 2013).
Concepts and differences-
The theory of dark matter stems from the fact that there is not enough normal matter, as the gravity of normal matter isn’t strong enough to form galaxies and complex structures. The stars will more likely be disorganized and not form galaxies. Hence we know there is some exterior reason, something that does emit or reflect light, something dark. All we know is that there is something out there, there is a lot of it and it has something to do with gravity. The most popular idea is that within the cosmos there is a dominant source of gravity which is an unidentified type of mass which cannot be seen by the naked eye known as dark matter. Dark matter
