Speedy Star Found Near Black Hole May Test Einstein Theory

I came across this and thought it was really cool, I have always thought black holes were very interesting. So I am sharing it here.

This will also give scientists an opportunity to test out the Theory of Relativity (e=mc2+p2c2) on a cosmic scale, which is completely awesome.

Now back to the story.

The faint star, called S0-102, orbits the black hole in 11.2 years, making it the closest large object known in the vicinity of our galaxy's superdense center. The star travels at speeds of up to 6,600 miles (10,600 kilometers) per second and is in a stable, if changeable, orbit.

Einstein's theory says that mass can warp space and time, and that has been proven many times over. But the theory has never been confirmed around an immense black hole—where traditional physics is known to break down—or on the scale provided by Sagittarius A and the stars around it.

The story goes on to discuss how technology has advanced over the past 25 years or so, that now we can see these stars that are so close to the Event Horizon
we can measure how they are being effected by black hole.

They have discovered two stars so far that are in orbit very near the black hole. It is the fact that two stars have been found there that will allow them to conduct these tests. Since two have been found they are expecting that more may also be found near the area.

"It is the tango of S0-102 and S0-2 that will reveal the true geometry of space and time near a black hole for the first time," study co-author Ghez said in a statement. "This measurement cannot be done with one star alone," said Ghez, whose study appears today in the journal Science.

Anyone who is more knowledgeable about this kind of stuff, please share with us. Dose anyone know exactly what tests might be performed, or how they would be conducted?

Looking forward to hearing your thoughts.

Here is an article going a bit more into detail:

They are essentially looking for deviations from an elliptical(newtonian) orbit.
