Albert Einstein developed the theories of general relativity and special relativity. He also did work in quantum theory. (He won a Nobel prize for his work with light.)
One exception is at the quantum level, where gravitational effects are often overshadowed by other fundamental forces like the strong and weak nuclear forces. In extreme conditions such as black holes or the Big Bang, the laws of gravitation break down as they interact with other physics theories like general relativity and quantum mechanics.
Stephen Hawking helped develop the field of theoretical physics and cosmology by working on the concept of black holes, the theory of general relativity, and the nature of the universe's origins and evolution. He also made significant contributions to the study of quantum mechanics and the search for a unified theory that could explain all physical phenomena.
That has been a topic of much debate since th1900's.

Theoretical Physicist. Raj is an Astro Physicist, Leonard is an Experimental Physicist.
Einstein’s Theory of Relativity changed how we see the universe. It explained space, time, and gravity in ways that transformed physics and astronomy. It’s why GPS works so accurately and even paved the way for nuclear energy and space exploration. It also sparked big debates about how we understand reality itself.
Some of them are 1) Big Bang Theory 2) Super string theory 3) General Relativity 4) Special Relativity 5) Quantum Theory
Some other theories humans have devised are:The Big Bang theory of cosmological expansionThe theories of general and special relativityThe germ theory of diseaseAtomic theory and quantum mechanics

Quantum cosmology is a field attempting to study the effect of quantum mechanics on the formation of the universe, especially just after the Big Bang. Despite many attempts, such as the Wheeler-deWitt equation this area of interest has yet to be fruitful. Quantum cosmology is a branch of quantum gravity.
A big deal in physical science is the study of quantum mechanics, which describes the behavior of particles at the smallest scales. This field has led to groundbreaking technological advancements such as quantum computing and has deepened our understanding of fundamental physical phenomena.
The big bang is based solely on the cosmological red shift, whereby the light from distant stars has lost energy, is assumed to be a Doppler red shift. However there is no direct evidence that that kind of a shift is actually what happens. There are also several "tired light" hypotheses.
One subject they're important in is physics. Statistics play such a big role in thermal dynamics that it is often referred to as statistical mechanics. Also, probability theory uses statistics as its base and quantum mechanics is all about probability.

He won a Nobel prize (it's not spelled "noble") for his discovery of the law of the photoelectric effect, not for his theories of relativity like many people believe.
Some popular theories in science that have gained widespread acceptance and recognition include the theory of evolution by natural selection, the theory of relativity proposed by Albert Einstein, and the Big Bang theory explaining the origin of the universe.
Stephen Hawking applied Quantum Mechanics to the mathematics of black holes, before this they had only been studied using General Relativity. With only General Relativity black holes could only form from the collapse of large stars, there was a minimum mass for a black hole, things only fell into a black hole causing its mass to always increase never decrease. With Quantum Mechanics added black holes could form early in the Big Bang before any stars existed, there was no minimum mass for a black hole, a black hole could emit particle radiation thus losing mass and the more mass it lost the faster it lost mass resulting in the black hole exploding in a flash of particle radiation and ceasing to exist.
