#Real black hole picture crack#
One physicist - I can't remember which, but he was speaking on that "How the Universe Works" black holes episode I linked to above - said that we need a new law of physics to help crack this puzzle. So trying to figure out what happens inside a black hole is like trying to solve a calculus equation using only algebra. The problem is that even Einstein's laws of relativity start breaking down inside such extreme conditions. It's my understanding that the matter is not totally annihilated, but what happens to it is a topic of intense debate among physicists. I don't know, and I'd love to know the answer to that question, too! and I can learn so much from.Įllen (author) from California on February 01, 2013: I`d much rather come here to your hub, of which you have done an excellent job. I did start to read Steven Hawkins universe, but i found it was too heavy for me at the time. Very Fascinating, I have not studied in depth on these black holes in the universe, but i sure know what it feels like to fall into one of them on this planet.
Jaydene from Alberta, Canada on February 01, 2013: It has also discovered some short gamma ray bursts caused by the collision and fusion of two neutron stars or by a black hole eating a neutron star. NASA's Swift telescope is designed specifically to pick up these bursts. The resulta ring of fire surrounding the blackest of shadowsis a powerful confirmation of Albert Einstein's theory of gravity, or general relativity, which was used to predict black holes 80 years ago. Astronomers now know that these gamma ray bursts are the signal of the birth of a black hole. Astronomers today revealed a picture of the gargantuan black hole at the heart of the nearby galaxy Messier 87 (M87). The biggest stars explode their outer shells in a supernova, while their massive core collapses all the way into a black hole.Īt the moment of collapse, massive stars emit extremely high energy bursts of gamma rays for a few seconds. Stars larger than our sun compact into neutron stars, super-dense remnants. Stars the size of our sun pack down into white dwarfs, small cold cores. Once their fuel is used up, stars implode. The Event Horizon Telescope Collaboration observed the supermassive black hole at the center of M87, finding the dark central shadow in accordance with Gener.
(The black hole left behind may be as small as 2.5 times the sun's mass, and some are less than 20 miles wide).Īll stars are engaged in a deadly tug-of-war between the force of gravity, which tries to make them contract under their own mass, and the outward thrust of their core's thermonuclear explosions.
"Stellar Mass" black holes started out as giant stars at least twenty times the mass of our sun.
