Answer 1

Answer:

Explanation:

One of the landmark discoveries of the twentieth and

twenty-first centuries so far is the discovery of Gravitational

Waves (GW). The existence of GW was predicted exactly 100

years ago by Albert Einstein based on his General Theory of

Relativity. It is interesting to know that he did not believe

that the GW will be discovered in the laboratory. Why? It is

because the amplitude of the GW will be so small (10-21m) that

no experiments will be able to measure this small displacement,

corresponding to about 1 millionth of the diameter of proton.
