Light detected from behind a black hole

The unexpected discovery succeeds in proving Einstein's theory of general relativity right once again.
During recent observations of x-rays flaring from a supermassive black hole at the center of a galaxy almost two billion light years away, scientists picked up something they hadn't expected to see - peculiar 'luminous echoes' from an unknown origin.

To add to the mystery, these echoes were smaller and arrived later than the x-ray flares.

The scientists soon realized that what they were witnessing was something very special - the first direct detection of light from behind a black hole.
Einstein had previously described how this was possible because massive objects like black holes can literally warp the fabric of the universe - curving and distorting spacetime.

"Any light that goes into that black hole doesn't come out, so we shouldn't be able to see anything that's behind the black hole," said Stanford University's Dan Wilkins.

"The reason we can see that is because that black hole is warping space, bending light and twisting magnetic fields around itself."

It seems that - once again - Einstein was right all along.

Docyabut2, you made my day, thanks very much for sharing this. This is truly amazing and it also again has proven that Einsteins General Theory of Relativity is spot on. I don't think that many reading this will understand how monumental this discover actually is, stuff like this makes me feel like a giddy child! “Fifty years ago, when astrophysicists starting speculating about how the magnetic field might behave close to a black hole, they had no idea that one day we might have the techniques to observe this directly and see Einstein’s general theory of relativity in action,” said Roger Bland...

You know Zep73, I am a big Einstein Fan and I find it amazing that during the time frame when he wrote his papers on Special and General Relativity that these concepts could have even been considered. In late 1919 Sir Arthur Eddington performs the first experimental test of Albert Einstein's general theory of relativity by taking photos of the Sun during a solar eclipse  which successful proves that not only can strong gravitational fields bend light and it can also warp space-time.  While Newton was Einsteins personal hero, he was unable to agree with Newtons Universal Law of Gravity. To Eins... [More]

In contrast to what their name implies, supermassive black holes can be one of the brightest sources of continuous light in the universe. Just gives me a heaven :)the Bible tells me Jesus came from the light

Or... This so called black hole is actually an air bubble the wall of the gigantic glass jar that we actually live in!

I was thinking of a doctor with a flashlight in his hands during a physical examination.

Does light actually bend?...or does it simply appear that way because ,sometimes, the space it is traveling through is (gravitationaly) curved/bent??      .     . I suspect that the bending of space simply proves that space is made of something, rather than nothing,. .?    Which means, space has mass...not that light does? Or, I am completely clueless?   ..that is probably,  a higher probability.  ?

to add Stephen William Hawking did say, the black hole leads to another universe. If so the light behind the black hole could be heaven.  A lot of people say in their NDE `s they go though a tunnel and to the light
