Einstein's Dream
The Grand Unified theory is one simple mathematical model which expresses all the forces that governs the universe, from the quantum level to the macroscopic level. Its a quest in merging both Quantum Mechanics and General relativity. And it is of course one of the greatest unsolved problems in physics. Einstein's dream was to achieve this stage. But unfortunately, he wasn't able to. But physicists of our generations has found a candidate which might give us an ultimate answer.
General Relativity
Physicists wanted to know the reality behind it. So they began exploring and started working on constructing a framework which shows us the existence of space-time curvature. After everything they decided to launch a satellite -Gravity Probe B(GP-B) on 2004. The mission's aim was to measure the space-time curvature near the earth. And the results were finally proved that there is existence of space-time fabric and the curvature of space-time fabric is due to the presence of mass which explains the gravity taking place there. Einstein was right. All physicist were amazed by this true fact. After almost 100 years Einstein's theory was proved right experimentally. And far more than that Einstein was even able to calculate the speed of gravity i.e the speed of gravitation waves in the space-time fabric. In general relativity theory the speed of gravity was equivalent to the speed of light in vacuum. The paper explained all the forces that governs the macroscopic world. Its quite strange that Einstein got Nobel prize for Photoelectric effect rather than this beautiful mathematical model.
The idea of General Relativity was thought by Albert when he pondered over light and was focusing on his earlier paper i.e Special Relativity which was published in 1905. Special Relativity deals with the speed of light. It says that speed of light is an universal constant, it does not change relative to anything.
Most of the people know that the light travels in a straight line. But that isn't always right, light bends due to gravity. It seems quite bizarre but it is the truth. As I've already mentioned before, scientists always look for evidences for the truth- as General Relativity predicted it. This is apparently known as the Gravitational lens. This is the phenomena explains the bending of light. This theory was confirmed in 1919 during a solar eclipse, when Arthur Eddington, a British Astrophysicist who observed the light from stars passing close to the Sun was slightly bent, so that the stars appeared slightly out of position. Einstein once again was right. He almost predicted most of the things which explained the macroscopic level of our universe. This was a huge turning point in understanding our cosmos. A legend who predicted most of the things theoretically. The only tool which he used to explain all these extraordinary and fascinating theories was Mathematics. All started from this Genius, who worked as patent clerk in a Swiss Patent office in 1903...

General Relativity
General Relativity is geometric theory of gravitation published by Albert Einstein in 1916. Well, we all might be familiar with the Newtonian Gravity. But there is far more interesting than that. The attraction force between two bodies as Newton predicted it as the mysterious gravitational pull was well known to Albert Einstein than the father of gravity. Albert theoretical found that the curvature of the space-time is responsible for gravity. Space-Time- A four dimensional world where space is 3-D and time as 1-D.

Physicists were dazzled after reading his paper. But some theoretical physicist thought this idea was a misconception , whereas the others wanted it to be experimentally proven as to be believed, because science has always been this way. Only if it was experimentally proven or witnessed, people will start believing in it. In fact, Richard Feynman has quoted that "It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong".
