Theory of General and Special Relativity are both immensely well known theories that discuss gravity in some aspect or another.
The chief difference that can be made between them is the level of completeness. But what exactly does each theory talk about?
General Relativity discusses the laws of gravitation and its relation to other forces of nature.
Special Relativity discusses certain phenomena in the absence of gravity.
General Relativity also explores the astrophysical realm more closely than Special Relativity does.
Both theories are strangely intriguing to learn about.
Many insights of Albert Einstein are now part of popular imagination: black holes, time warps, and wormholes show up in movies and books.
Less famous, but probably the most revolutionary part of Einstein's phenomena, is a simple idea that shows how pieces fit together and illuminate the road ahead.
Scientists know four forces - things that attract or repel one object from another. The strong force and the weak force operate only inside the centres of atoms. The electromagnetic force rules objects with excess charge, and gravity directs objects with mass.
People have long speculated about gravity. While ancient Greek and Indian philosophers observed gravity, it was the insight from Isaac Newton that made it possible to measure and predict the phenomenon.
Quantum Entanglement is a phenomena that describes how the measurements of spin, momentum, and position can all be same between two unique particles.
The main issue is that entanglement can only exist for brief moments because any sort of observation or change in environment can break it.
Entanglement is interesting because it can fit well into other theories as well. One example is Hawking Radiation. The very premise of the theory is that an Entangled Photon Pair is separated at the surface of a Black Hole.
How interesting would it be if humans could be entangled with each other?
