"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

The space telescope's image of a odd-looking spiral galaxy is, in reality, two distant galaxies overlapping each other.

This might change our understanding of the universe. Scientists have developed a theory that eliminates the problem of ...

In it, he suggested that gravity is not a force, as Newton had believed, but the result of a curvature of the space-time continuum -- the four dimensional world in which we live. He used a thought ...

That describes the largest structures in the universe in terms of curvature of space and time. On the other hand, we have quantum theory. Which very successfully describes the elementary particles.

He discussed space of four or more dimensions, and paved the way for the General Theory of Relativity Just 100 years ago the young Bernhard Riemann gave his famed paper on the foundations of geometry.

Don and Brian Cleaver are the father-and-son team from Toms River who launched a Jersey Shore aeronautical adventure into the heavens from Jackson.

Gravitational physicists explore the implications of the general theory of relativity, in which gravitation is a consequence of the curvature of space and time. This curvature thus controls the motion ...
