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
Before the discovery of Dark Energy cosmologists had two models of how the universe’s expansion would end. In first scenario, there would be enough matter in the universe to slow the expansion to the point where, like the baseball, it would come to a halt and the gravitational forces associated with it would result in … Read more
Richard Feynman the farther of Quantum Electrodynamics believed Thomson’s double slit experiment provided a mechanism for understanding the wave particle duality of energy/mass because it clearly demonstrates their inseparability. The wave–particle duality postulates that all particles exhibit both wave and particle properties. A central concept of quantum mechanics, this duality addresses the inability of classical … Read more
Einstein’s Theory of Relativity tells us that nothing can travel faster than the speed of light in our universe however it did not preclude space expanding faster than the speed of light In other words because it allows for space to expand faster that the speed of light some things, like space itself can move … Read more
