US, WASHINGTON (ORDO NEWS) — The term space-time comes from the General Theory of Relativity (GR) Einstein, which allowed us to combine the three spatial dimensions with a time indicator, creating an integrated dynamic system.
Einstein established that space and time are indivisible, and all those interactions that occur between space-time and matter are gravity.
Based on GR, space-time is capable of distorting under the mass of a massive object. The greater the mass of the body, the more the space-time tissue around is distorted, which forces other, less massive objects, as it were, to “roll down” to the center of mass.
Light also falls into this gravitational “trap”. The phenomenon of refraction of a light beam near a massive cosmic body is called gravitational lensing.
