TO SEE THE PICTURE OF BLACK HOLE, PLEASE GO TO THIS FILE OF MINE
BLACK HOLES ARE MASSIVE BODIES IN THE UNIVERSE SO HEAVY THAT EVEN LIGHT CANNOT ESCAPE FROM THEM.HENCE THEY CANNOT BE SEEN, BUT COULD BE FELT.
This wind screen reminds me of my mental picture of a ‘BLACK HOLE’ that Stephen Hawkins theorized and that Einstein said that the light rays will bend around massive celestial bodies travelling on a ‘curved’ space.
Einstein’s theory was confirmed even in his life time. He was himself very humble and whenever he liked something he said so.
To test his theory that the light bends around massive bodies, the scientists got a rare opportunity to prove by observing the position of a star during a total solar eclipse. The position of the star was known and because it was almost directly, but only just, behind the sum when observed from Earth, it was impossible to see it during the day due to shining Sun. The rays from it reached us by just grazing the edge of Sun.
But when the Sun was blocked by the Moon (during the Solar eclipse), the star could be viewed and it was found that its position was somewhat changed from the known position. This only could be explained if it was accepted that the rays from the star have gone a little bending while passing from near the Sun. The pictures of this event which became hard proof of his theory were shown to Einstein. He said, “Beautiful”. The scientist who showed him those pictures said, “Yes, I know it is beautiful to have one’s theory proved thus”. Einstein said, “I am praising the pictures, and I had no doubt about the theory itself”.
