1 Black Holes And other mysterious matters of the Universe.

2 Definition of a Black Hole “An object whose gravity is so strong that the escape velocity from it exceeds the speed of light” (Comins G-1).

3 Speed of Light Light travels at a speed of 1.86*10^5 km/s. With light not even being able to escape it is impossible for galaxies or other black holes to escape a large enough Black Hole.

4 Technological Advances Hubble Telescope Computer simulations Other forms of telescopes which pick up infrared and x-ray waves in order to produce a picture of things the hubble cannot even look at. Physicist such as Stephen Hawking which help to advance new theories on such things as dark matter and Black Holes.

5 Formation of Black Holes Stars or galaxies collapse upon themselves sometimes causing the creation of a black hole. (Hawking 41).

6 Inside the Black Hole This means that the star under its own weight and gravity slowly begins to contract upon itself starting to increase its gravitational pull until light itself cannot escape due to such gravitational forces, and it also helps to illustrate that inside a Black Hole time itself would become irrelevant and eventually end. (Hawking 41).

7 Theories on the Black Hole There have been many theories on the existence of a black hole but none as great as the M-Theory, which states shows the ability of a gravitational force that can put pressure upon billions and billion of particles which make them collide with one another which is believed what happens inside a black hole.

8 Black Hole Entropy Formula Akc^3 4hG S=Black Hole Entropy A=to the area of the event horizon of a black hole C=speed of light K=Boltzmann’s Constant G=Newton’s Gravitational constant h=Planck’s Constant

9 Black Holes aren’t black Black Holes are really a transparent color, and appear black because of the stars on the outer edge of the black hole as well as the light being pulled into the black hole help to intensify the color of the sky near the black hole which is black. (Hawking).

10 Can Black Holes Duplicate Themselves? “When big black holes give birth they eat their offspring, according to a simmulation of these cataclysmic events. These acts of cosmic cannibalism could soon be picked up by space-based detectors of gravitational waves” (Chowen).

11 Locations Black holes are thought to reside at nearly the center of every galaxy which helps to keep everything in balance with each other. (Cowen)

12 Even in the Milky Way A black hole was found to reside at the center of the Milky Way Galaxy, but don’t worry before any of the nearby stars reach this black hole they will have estinguished themselves. (Cowen)

13 Other mysterious matters of the Universe Dark matter- a energy source which is believed to be neutrinos with other known elements make up 27% of the material in the universe. So what makes up the other 73%? Worm Holes- an unknown source which is believed to be a space-time continuum which leads into other dimensions. (Pasachoff).

14 Black Holes The End!!!!!!!!!
