At the surface such a body is enveloped in a shell of relatively cool matter. Now suppose a great attracting body, such as another sun,…
According to the theory of relativity, time dilation is a difference in the elapsed time measured by two observers, either due to a velocity difference relative to each other, or by being differently situated relative to a gravitational field.

The first automatic partially reusable spacecraft was the Buran-class shuttle, launched by the USSR on November 15, 1988, although it made only one flight and…
While the consensus among physicists is that gravity will attract both matter and antimatter at the same rate that matter attracts matter, there is a…
Nearly polar orbit around a planet, in which the satellite passes over any given point of the planet’s surface at the same local mean solar…
