Astronomers have seen the back of a black hole for the first time

Is it possible to see the back of a black hole?

Black holes trap anything falling inside of it. They don’t emit light, but just trap light. If so, normally we can not see the back of a black hole, we shouldn’t be able to see anything that’s behind the black hole.

However in 1915, Einstein’s theory of general relativity predicted that the gravitational pull of black holes is so strong that they warp the very fabric of space, twisting magnetic fields and bending light…

Experts accepted the theory, but have been unable to directly observe the phenomenon… Until now.

And now astronomers have seen the back of a black hole for the first time! They were able to separate out the echo that comes from behind the black hole and the light that gets bent around into our line of sight.

While scientists have seen light bending around a black hole before, this is the first time they have been able to see the phenomenon happening from the other side.

Albert Einstein is right Again!

Einstein proposed that massive objects warp and curve the universe, resulting in other objects falling in and this is what we experience as gravity.

(Gravity is a curvature in space time as described by Einstein’s General theory of relativity. Matter does not simply pull on other matter across empty space, as Newton had imagined. Rather matter distorts space-time and it is this distorted space-time that in turn affects other matter.)

So a black hole can warp the very fabric of space, bending light and twisting magnetic fields around itself. Thus a black hole can act like a lens, making us see the back of a black hole. And this happened now!

Yes, Astronomers have detected light behind a black hole deep in space for the first time! The research published in the journal Nature has reported this.

Black holes warp the very fabric of space

An international team of researchers were studying a feature known as the corona on a supermassive black hole 800 million light years away, but high-powered X-ray telescopes also picked up unexpected “luminous echoes” coincidentally in the form of X-rays – which were being emitted by the far side of the black hole.

The discovery confirms Albert Einstein’s theory on general relativity. The gravitational pull from black holes essentially bends light rays around themselves, giving scientists their first glimpse of what lies behind.

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

Albert Einstein’s 1915 theory of general relativity is proven right again – black holes warp the very fabric of space!!

        I enjoyed the post, black holes are so fascinating to me, I am so old that I can remember when they first started talking about black holes. Cool as it all is, reading about far-out space literally boggles my mind. 🙂

            yes, very much. I like to read about space and the universe, etc. Just read a very interesting article on the Sun, new information for me.

            When I was working on my BA degree, a professor invited me to take his course on astrophysics…I literally laughed out loud! But I did take the course, and learned about the magnitude of stars and how scientists “read” the elemental make-up of various celestial bodies. I would like to know more about geology, how the Earth was formed into mountains and rivers…etc.

            This is pretty amazing and i do really appreciate your urge to learn new things

            Eventually every one of us gets to the point where their leisure time involves less-strenuous activities such as reading. I also do beading,

            Thanks a lot for remembering me and sharing it.. actually there are a lot of such mysterious things happenings .. who knows if there are truly aliens..

            It does logical that there are intelligent beings out there someplace. I read recently someone said they believe it probable that the reason we (humans) have so many mysteries is that we are not capable of understanding beyond a certain level. We don’t know what we don’t know… 🙂 I hope that when we humans actually do encounter “others” we will be intelligent enough not to kill them before we get to know them. It’s like a little bug on the sidewalk…the first thought is to stomp on it…but why? Human nature I guess.

Do you have something to tell me on this post?
