Theory of relativity

The theory of relativity, or simply relativity in physics, usually encompasses two theories by Albert Einstein: special relativity and general relativity. Concepts introduced by the theories of relativity include spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction.

The term "theory of relativity" was based on the expression "relative theory" (German: Relativtheorie) used in 1906 by Max Planck, who emphasized how the theory uses the principle of relativity. In the discussion section of the same paper, Alfred Bucherer used for the first time the expression "theory of relativity" (German: Relativitätstheorie).

Scope

The theory of relativity transformed theoretical physics and astronomy during the 20th century. When first published, relativity superseded a 200-year-old theory of mechanics created primarily by Isaac Newton.

In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmology and astrophysics predicted extraordinary astronomical phenomena such as neutron stars, black holes and gravitational waves.

"Relativity Theory" is an episode of The Outer Limits television show. It was first broadcast on February 27, 1998, during the fourth season.

Opening narration

Plot

Biologist Teresa Janovitch is a civilian among military men, traveling on the Resource Survey Vehicle Cortez to Tau Ceti Prime in search of minerals for an Earth that has squandered its own. Initial signs indicate that the planet is both uninhabited and rich in mineral resources, which could mean a million dollar payday for both the crew and the company that owns the Cortez. But on the first exploration, the crew is attacked by gigantic and apparently primitive aliens.

After initial casualties, command of the mission technically, by regulations, falls to Janovitch, who favors further investigation and a non-aggressive approach towards the aliens; it may be possible to either reach some accommodation with the aliens or find an area of the planet where they do not live to extract resources. But she is overpowered by her crew, Sgt. Adam Sears, a veteran of pacification missions on Earth, who favors annihilation of the new race, and Corporal Charles Pendelton; the crew are impatient with the idea of negotiating with alien savages after they have been responsible for killing members of their crew, and greedy to claim their reward for finding a planet so rich in resources.
