Space, Time, and Gravity in a Quantum Universe

Quantum Relativity is part of the on-going story of man’s attempt to understand the rules of the universe, particularly the laws of gravity
Gravity
In 1686, Sir Isaac Newton published his great work, Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy). In this book, Newton released his theory of gravity, the first mathematical theory of gravity ever. In order to create his theory, first Newton had to invent a new form of mathematics, Calculus.
Relativity
In 1905, Albert Einstein shocked the world with three papers. Before he published these papers, Einstein was a clerk in the Swiss Patent office – he had graduated from college with a bachelors (4 year) degree, but his professors considered him a rather indifferent student who was not talented enough to warrant a position in graduate school to pursue a Doctorate degree. Einstein’s three papers were:
- Brownian Motion – after this paper was published, everyone agreed that matter was made up of atoms. The atomic theory is perhaps the most fundamental part of quantum mechanics.
- The Photo-Electric effect – in this paper, Einstein coined the work “photon,” and put us firmly on the road to quantum mechanics.
- Special Relativity – in this paper, Einstein explained that the speed of light was an absolute constant. Everyone who measures the speed of light will get the same number, regardless of how fast they are moving and how fast the light source is moving, and nothing can go faster than light. Special relativity tells us that space and time do not exist as separate entities, as Newton thought, but rather as one union, which we call space-time.
