Scientists have now announced a new discovery called the gravitational waves, ushering now a new chapter in astronomy.
The discovery can be summarized as below
Aristotle theorized that “all objects move towards their natural place”. However, his idea of a natural place was used with the ideas with elements of fire, air, earth and water.
However, Galileo made a change to Aristotle’s discovery, when he found that all objects fall to the earth with the exact same speed regardless of weight.
Later, Sir Issac Newton, calculated that the attraction between two bodies is equal to the product of the masses divided by the square of the distance between them ie: F=G(m1m2/r^2). This equation according to Newton is true for both on earth and space and this explained the tides. But although Newton agreed that what goes up, must come down, he did not know why.
This was when Albert Einstein and his general theory of relativity came into play.
In this Einstein said, gravity is the warping of work and time. He also theorized the existence of gravitational waves ripples in the fabric of space and time.
Ever since, scientists had been looking for evidence. That’s when the Lazer Interferometer Gravitational-Wave Observatory (LIGO) made a discovery. After years of trying to observe Einstein's theory of gravitational waves, researchers say they have discovered merging of two black holes into one. This merging helped the physicists to figure the gravitational waves. This discovery would make the world look at waves different from radio waves, UV waves and gamma waves.
