Origin of the Universe
The Origin of the universe
The Origin of the Universe by Bilal Qureshi
Since the dawn of intelligent man, humanity has speculated about the origins of the universe.
There is evidence, which indicates that the universe started around 15 billion years ago.
This is probably the greatest discovery imaginable; however, the universe still seems to be a very controversial subject.
Most scientists agree that there was a beginning but there is a lot of speculation of how it (the universe) actually started. The much-celebrated Greek philosopher, Aristotle, denied the fact that there ever was a beginning. He and his associates believed in the eternal existence of the universe, they also tried to prove that the universe was static, and was unchanging in time. However, there is evidence, which suggests that the universe is changing with time.
Geologists have discovered meteorites on the earth that have existed for many thousands of millions of years, way before the earth came into existence.
A second principle, which concretises the beginning of the universe, is the second law of thermodynamics. As I quote the cosmologist Sir Arthur Eddington, said,
"Don't worry if your theory doesn't agree with the observations, because they are probably wrong.' But if your theory does not agree with the 2nd law of thermodynamics then it is in serious trouble".
The second law states that disorder (which is measured by entropy) always increases with time. Therefore, the idea that the universe existed forever is contradictory, because the second law implies that there was a beginning.
Explained:
If the universe has an infinite number of stars then the night sky should be uniformly bright as the surface of the sun. This essentially is Olbers' paradox
