Gravitational wave
What is a gravitational wave? Scientists have recently found the first evidence on gravitational waves after the explosion of two black holes collided together. It ' s a swell in the texture of space and time. Envision that space is a mammoth sheet of elastic: things that have mass make that elastic sheet twist, similar to a knocking down some pins ball on a trampoline. The more mass, the more that space gets twisted and contorted by gravity. For instance, the reason the earth circumvents the sun is that the sun is extremely monstrous, creating enormous contortion of the space around it. On the off chance that you simply attempt to move in a straight line around such a major twisting, you will get yourself really moving around. That is the means by which circles work: there ' s not a real constrain pulling the planets around, simply twisting of the space. Gravitational waves are delivered at whatever point masses quicken, changing the contortion of space. Everything with mass and additionally vitality can make gravitational waves. In the event that you and I began to move around each other, we would likewise bring about swells in the texture of space and time. Be that as it may, these future to a great degree little. Presently gravity is exceptionally powerless in the size of alternate strengths in the Universe, so you require something super monstrous moving, quick, to make the huge swells that we can recognize
