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
