Fastest Star Ever Seen is Moving at 8% the Speed of Light
A star orbiting the black hole in the center of our galaxy is moving so fast it can only be described relativistically.

General relativity tells us that everything, even light, is affected by the mass of an object. When a beam of light passes near a large mass, its path is deflected. This shift in the direction of light is known as gravitational lensing, and it was one of the first confirmed effects of Einstein’s theory.
In another first, the latest gravitational wave event to be detected came from the merger of two black holes of vastly different mass.
Gravity was the first force of nature to be realized, and in the centuries since we first cracked the code of that all-pervasive pulling power, scientists have continually come up with clever ways to test our understanding. And it’s no surprise why: the discovery of a new wrinkle in the gravitational force could open up …

A new study led by Caltech researchers show that light can be reflected off of a black hole’s disk by its powerful gravity.
When it comes to cosmological theories, the Big Bang theory has historically had only one big contender – the Steady State Hypothesis
Using data from Hubble and the gravitational lensing technique, a team of astronomers have found definitive evidence that Dark Matter is indeed “cold”.
Using NICER data, two teams of researchers were able to map the surface of a pulsar for the first time in history!
When a NASA engineer announces a new and revolutionary engine that could take us to the stars, it’s easy to get excited. But the demons are in the details, and when you look at the actual article things look far less promising.
“Are the dilation calculations correct” the jump coordinator asks you as he approaches your desk. You look over some papers in front of you that contain various equations scribbled down with certain values circled. The equations are more for your own sense of security, as the computer console in front of you displays the same …
