Theories of the Universe

The Universe is ever expanding, and its accelerating. But what could possibly imply that the universe could collapse into a single atom? Studies by astrophysicists shows that the universe is approximately 13.8 billion years old. So, the universe has a beginning and an end? Or is it possible that the universe is a repeating cycle? String theory was proposed in the 1960’s. It was developed to be a unity between Quantum mechanics and Albert Einstein’s Theory of Relativity. This theory explained most of the events that occurred around the time of young universe. The theory is that all matter are complex strings whose vibrations can determine the properties. Then came the Big Bang Cosmology, along with the idea of Inflation. These theories state that at the time of birth of the universe, it became very large in such a small time, when the universe was less that a second old. This sudden inflation, with huge gravitational differences, caused the formation of huge splotches found in the unive...
