Spacetime continuum

Spacetime

In physics, spacetime (or space-time, space time) is any mathematical model that combines space and time into a single continuum. Spacetime is usually interpreted with space as being three-dimensional and time playing the role of a fourth dimension that is of a different sort from the spatial dimensions.

An Epic Space-Time Experiment

Spacetime is warped and twisted by the mass and spin of the earth.



Einstein was right again. There is a space-time vortex around Earth, and its shape precisely matches the predictions of Einstein's theory of gravity.

Researchers confirmed these points at a press conference at NASA headquarters where they announced the long-awaited results of Gravity Probe B (GP-B). The mission is teaching scientists about some of the most basic properties of the Universe, which can ultimately help astrobiologists determine how and where to search for habitable worlds. GP-B is also advancing space technologies for future mission in orbit and beyond.

"The space-time around Earth appears to be distorted just as general relativity predicts," says Stanford University physicist Francis Everitt, principal investigator of the Gravity Probe B mission.
