3. What Are They? A region that has so much concentrated mass that nothing, not even light, can escape its gravitational pull

4. How Are Black Holes Formed? Black holes are formed from the remains of a supernova Fusion uses most the energy The gravity of the supergiant star increases and gets denser No energy is left to repel the matter Force of gravity increases so much that a black hole is formed

5. How Do Black Holes Work? Black holes are so dense that they pull in stars and planets So much gravitational force that nothing can escape, not even light Singularity is the middle point of a black hole The event horizon is the point of no return Travel faster than speed of light to escape black hole

6. What Are Their Impact on Their Surroundings? Black holes are thought to pull in planets and stars They affect gravity, mass, and time Mass has no volume and time stops They can hide in a group of galaxies or stars They are thought to be the center of every galaxy

7. How Are Black Holes Detected? Scientists have found some ways of detecting black holes They search an area with an accelerated disk Search for X-RAYS given off by stars that were ripped apart.

8. What Have Scientists Discovered About Black Holes? Scientist discovered that black holes may have a link to time travel Black holes effects mass and time. Mass has no volume and time does not pass Found ways to use computers to create images of black holes Humans could use black holes to benefit their own needs

9. How Are They Linked to Time Travel? Two Black holes from different galaxies connect This creates a wormhole At this center point there is supposedly a shortcut in space This shortcut can transport an object from point one galaxy to the other in a few hours

10. What Are the Different Types? Schwarzchild- don’t rotate and have no charge Reissner- Nordstrom- don’t rotate but have a charge Kerr- rotate but have no charge Kerr-Newman- rotate with a charge

11. Conclusion Allow us to understand the universe systems better Black Holes could have many versatile uses Disposal of waste materials Time travel to future Transportation device Ultimate weapon
