Why did Einstein's Theory stun the world of science?

As most of us know Albert Einstein was a scientific genius who was born in 1879 in Germany.  He developed the general theory of relativity, one of the two pillars of modern physics. Einstein's work is also known for its influence on the philosophy of science.  Einstein made many contributions to the field of theoretical physics. He revised Newton's laws of gravity to make them more accurate.

We call what he developed the theory of relativity. It is actually two theories. The first is called Special Theory of Relativity. This theory states that it is impossible to determine whether or not you are moving unless you can look at another object.

The second is the General Theory of Relativity. It is the one which redefined the laws of gravity. The theory explained how time and distance may change due to the 'relative' or different speed of the object and the observer. It broke new ground in the world of science. In 1921 , Einstein won the Nobel Prize in Physics for his services to Theoretical Physics. 

But GPS systems owe a debt of gratitude to Einstein and his thought experiments, without which they would not exist at all. The highly precise clocks have oscillators that function not on springs or pendulums, but atoms. The level of precision required for satellites is down to this atom clock, whose ticks must be known to an accuracy of 20 to 30 nanoseconds. Because the satellites are constantly moving relative to the Earth, effects predicted by Einstein's theory must be taken into account. 

In particular, the pull of gravity is stronger on Earth than in the satellite's orbit, meaning time is passing marginally faster in the latter than it is in the former. The precision of atomic clocks makes the desired accuracy achievable and GPS technology corrects this discrepancy to make the location accurate.
