A white hole, in general relativity, is a hypothetical region of space time which cannot be entered from the outside, but from which matter and light may escape. In this sense it is the reverse of a black hole, which can be entered from the outside, but from which nothing, including light, may escape. (However, it is theoretically possible for …

What is nature’s most powerful, most destructive, most dangerous form? Some would say an earthquake, others a cyclone.

A vacuum, in theory, is a space entirely devoid of matter. But no method has been devised for producing one. In practice, therefore, a vacuum in an enclosed space from which air or other gasses have been expelled to such an extent that the pressure inside is below that of the atmosphere. There are partial vacuums and high vacuums, according …

A theodolite is a surveying instrument used for measuring horizontal and vertical angles. To measure long distances we use a system known as triangulation we can use, it, for instance, if we want to know the distance to the moon. Astronomers measure the angle of the moon above the horizon at two places on the earth’s surface as far apart …
