This post is about my views about the theory of everything in science. After stating what I mean by the title and the problems associated with it, I shall talk about three disciplines/concepts that are seemingly independent, but as I shall try to reason, are tripartite secrets to understanding the greatest mysteries of our universe.
If you’re looking for something lighter, and a significantly shorter answer to a similar question, you may want to read this post. If you’re here for the real deal, read on.
“… if we discover a complete theory, it should in time be understandable by everyone, not just by a few scientists. Then we shall all, philosophers, scientists and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason — for then we should know the mind of God.”
– Stephen Hawking (A Brief History of TIme)
Wait, What Theory ?
The “Theory of Everything” is a label given to the persistant ongoing effort in the scientific community to come up with a theory of physics which would explain and account for everything in the observable universe. For example, if you have an infinitely large table with billiard balls that follow Newton’s laws of motion, you can compute and predict everything about their future and also explain their present and past behavior.
To cut the long story short, everything in the universe is made of particles* which interact with each other based on forces. There are only four fundamental forces. If you can explain how all four behave, you can theoretically predict and explain everything about our universe. As a matter of fact, physicists have unified 3 of the fundamental forces and only one does not fit into their picture (wiki: GUT) – the force of gravity.
Seemingly, we are very close to the ultimate theory of everything in science!
