(via Minute Physics) This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it's gravity, curved space) through to the concepts of how curved ...

[Translated by Dr. Robert W. Lawson.] THERE is something attractive in presenting the evolution of a sequence of ideas in as brief a form as possible, and yet with a completeness sufficient to ...

The stars of the Milky Way orbit a gargantuan black hole called Sagittarius A*, which is generally quiet as viewed from Earth, except for ripping apart the occasional object that ventures too close.

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

STENNIS SPACE CENTER, Miss.—David Giger bounded up 26 steel steps and emerged onto a rocket engine test platform. Off to his left, an unbroken stand of stately pine trees spread out over the ...

For the first time ever, researchers have watched a star race past the supermassive black hole at the heart of the Milky Way, verifying that its motion showed the effects of general relativity, as ...
