Between gravity and gravitational waves... lies relativity

ArabiaWeather.com - Khatim Amer - The general law of gravitation states that there is a force of attraction in the universe between any two bodies, and this force is directly proportional to the product of the two bodies and inversely proportional to the square of the distance between the two bodies, but what is the difference between gravity and gravitational waves?

The idea of gravity is that the greater the mass of a moving body, the greater its gravitational pull. Hence, we can imagine gravitational waves in space, which are ripples that transfer energy through the universe.

The well-known physicist Albert Einstein described in his theory of relativity how gravitational waves work that pull and push space-time (time and space) and how objects and black holes move in gravitational waves, but this was not proven until recently, specifically before the massive technological revolution that we are witnessing. currently.

Gravitational waves are characterized by the fact that they extend through the universe unhindered, regardless of what gets in their way, and this is what makes them unique and distinct from light or sound.

A number of scientists have made several attempts to prove the existence of gravitational waves , but they failed due to the great difficulty in finding and measuring them, as they require the availability of ultra-sensitive sensors, because when these waves reach the earth, they become very small and a thousand times smaller than the size of the atomic nucleus.

While the European Space Agency (NASA) recently launched a satellite that may help measure very subtle changes in space.
