Here is an amazing fact: The matter we know that makes up all stars and galaxies only accounts for 5% of the content of the universe. The rest is called dark matter. It does not interact with the electromagnetic force and therefore does not absorb, reflect or emit light, making it extremely hard to spot. … Read more
In 1933 Fritz Zwicky a Swiss astronomer, was trying to measure the mass of a galactic cluster using two different methods. First he tried to infer it from the rational speed of the galaxies around the center of the clusters. Just like kids on a merry-go-round have to hold on to avoid being ejected, galaxies … Read more
History has shown the advantages to reformulating or expanding an existing theory or law to a wider environment. For example Kepler’s Laws are wonderful as a description of the motions of the planets. However, they provide no explanation of why the planets move in that way. Moreover, Kepler’s Third Law only works for planets orbiting … Read more
Would the existence of Dark Matter affect Hubble’s laws and our understanding of evolution of the universe? In the article “What is Dark Matter?” Sept 10, 2007 it was shown that assuming space is composed of a continuous field of energy/mass would give an explanation for the gravitational component of Dark Matter that is consistent … Read more
Scientists have determined that roughly 70% of the Universe is dark energy while Dark matter makes up about 25%. The normal matter or everything ever observed with all of our instruments adds up to less than 5% of the Universe. The evidence for the existence of Dark matter comes from the detained analysis of the … Read more
