A black Hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole's “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos

Black Holes have long fascinated the imagination yet challenged discovery. Their extreme gravity, so strong light cannot escape, make them exceptionally difficult to see. Nearly a century after scientists suggested black holes might exist, the world has tools to see them in action.

Physicists Finally Confirm Einstein's Stunning Prediction About Black Holes. As predicted by Einstein's theory of gravity, there's a point at which material stops circling the black hole and falls straight down, plunging precipitously beyond the point of no return.

A White Hole is a hypothetical Region of Spacetime that acts as the Exact Opposite of a Black Hole.

The Relativity Theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old theory of mechanics created primarily by Isaac Newton.

The Universe (Latin: universus) is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy.

Science is the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.
