The following excerpt from NASA’s in its Astrophysics web site Dark Energy describes what we do and don’t know about Dark Energy. “More is unknown about it than is known. We know how much dark energy there is because we know how it affects the Universe’s expansion. Other than that, it is a complete mystery. … Read more
Quantum entanglement is defined “as a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently instead, a quantum state may be given for the system as a whole. For example, if a pair of particles is … 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
Can we justify defining the reality of an environment based on our inability to define its reality. The uncertainty principal of quantum mechanics tells us that we cannot know or observe the precise amount of energy contained in microscopic physical system over very short intervals of time. Some physicists feel that because they cannot know … Read more
