More than a century ago, Albert Einstein presented the theory of general relativity, also called the geometrical theory of gravity. He proved that no matter how weak or strong an object’s gravity is, it will fall in the same way.
According to his findings and the theory of relativity, the Earth and the Moon head in the same way towards the Sun following each other’ orbit. People were sceptical during those days, but Einstein’s ideas have gone through time and now they are supported by modern time scientists.
Recent studies show that the theory of gravity has passed the test of time and still stands. During the research, reference was made to Galileo’s conclusions. Hundreds of years ago he discovered that regardless of the mass, if you release several objects together at the same time they will reach the ground at the same rate.
But how about objects with extreme gravity? Is the same principle valid?
Even in this case, the answer is yes. A study conducted by an international team of astronomers tested the ground for this subject by studying three stars situated at about 4,200 light years from Earth. The interesting fact is that the stars were orbiting around each other.
The team’s findings were presented in a paper recently published by the Nature journal. They represent a huge step towards the future, but astronomers say that there is still a long way to go. They have always tried to understand how the Universe works and the latest data might help.
Furthermore, advanced telescopes will give them more chances of finding the best testing triple system. Who knows, they might even discover a theory more important than Einstein’s. It’s not easy, considering that the famous scientist promoted the idea of gravitational microlensing which was proven for the in 1919.
