According to a recent press release, “… scientists have observed ripples in the fabric of spacetime called gravitational waves…” The observation is said to confirm the general theory of relativity (GR), since large amounts of mass or energy distort spacetime, creating what we refer to as gravity.
In Einstein’s vision of the Universe, time and space are dynamic regions under constant change because matter creates “warps” or curves in both. Today, its interpretation views the Universe as a kind of geometric object that exists in a four-dimensional matrix: three space coordinates and one time coordinate are necessary in order to define a particle’s “world line” through history.
