Black Holes & white holes - Astronomy Project
Transcript of Black Holes & white holes - Astronomy Project
Hawking Blackholes violates fundamentally principle of physics Size Concluded that for every ounce of material a black hole absorbed into its core, it will radiate away an equivalent amount of energy from its event horizon. ''conservation of information'' 36 10 times the Mass of the Sun: Since there’s not physical link between a black hole centre and it’s event horizon, the two processes could not share any information.
Basic principle of physics says ''You can’t lose information'' Massive Black Hole 10 kg Million times as much as the Sun: 10 kg 31 Radius of 30 kilometers Radius of 3 Million kilometers A black hole is actually colder than empty space. There are special places in the universe
where that law can be broken. Thought to be inconceivable, that somehow things fell into the black hole, could have anything to do with the hawking radiation, which was coming out from very far from where the particles fell in.
Black holes will spend most of their lives eating stars and leave no record of what they had done. Nothing else of a universe does this.
A blast of a nuclear bomb might vaporize everything in sight, but, all that information is still in this universe, no matter how scrambled. Holographic principle Event horizon of a black hole is a two dimensional representation of a 3D object at its centre solves the problem of info lost.
Every object that falls into the black hole leaves its mark both at the central mass, and on the shimmering hologram at the event horizon.
When the black hole emits hawking radiation from the horizon, that radiation is connected to the stuff that fell in. Information is not lost, thus adhering to the basic physical principle of conservation of information. Conceded defeat Black holes can only suck matter and other items in their horizon (area) only. If the matter is out of that horizon then, it wont get sucked in. Won the black hole war Only stars that weigh considerably more than the Sun end their lives as black holes.

And the presentation software PREZI. Thank you! The known closest black hole to Earth is Cygnus X-1, located about 8000 light years away. Thermal equilibrium - is achieved when two systems in thermal contact with each other cease to have a net exchange of energy. Thermal Equilibrium State is Time Reversal Invariant...
According to Stephen Hawking White Hole = Black Hole Cosmic-thought experiment Video
