  4. Introduction to black holes How Are Black Holes made? Where are they found? How do we find them? Harvard-Smithsonian Center for Astrophysics Origins Education Forum - STScI Navigator Public Engagement Program - JPL

  5. 1915: Einstein’s Theory of Gravity predicted the possibility of black holes, but no one believed they actually existed! 1967: Term “Black Hole” coined 1970’s: Convincing evidence that black holes are realToday: NASA space telescopes have discovered evidence for black holes throughout the universe Albert Einstein

  6. What did Einstein say about Gravity? Mass distorts space - “curving” it Objects and light moving near the massive object are forced to take a curved path around the object. Just like the Moon orbiting Earth. Images courtesy of Professor Gabor Kunstatter, University of Winnipeg

  7. What is a Black Hole? An unimaginably dense region of space where space is curved around it so completely and gravity becomes so strong that nothing, not even light, can escape. Mass is so great in such a small volume that the velocity needed to escape is greater than the speed light travels.

  8. How much would you “weigh”? On Earth, let’s say you weigh 150 lbs. On the Moon, you’d weigh 25 lbs. On Jupiter, you’d weigh 350 lbs. On the Sun, you’d weigh 4,000 lbs. Near a Black Hole, you’d weigh over 20 TRILLON POUNDS !!!

  9. Where do black holes come from? • Three classifications of black holes: • #1- Stellar-mass: 3 to 20 times the mass of our Sun • #2 - Supermassive: Black holes with millions to billions of times the mass of our Sun • #3 - Mid-mass: In between stellar-mass and supermassive

  10. How do they form? #1 Stellar-mass: Black holes are made when a giant star, many times the mass of our Sun, dies. Most of the star’s atmosphere is blown into space as a supernova explosion. The star’s spent core collapses under its own weight. If the remaining mass is more than the mass of 3 Suns, it will collapse into a black hole. Supernova: Credit: European Southern Observatory

  11. Where do black holes come from? #2-Supermassive: Extremely massive black holes have been found in the centers of many galaxies - including our own! Credit: European Southern Observatory (ESO) - Very Large Telescope

  12. Where do black holes come from? #3 Mid-Mass: Scientists are finding these in the centers of large, dense star clusters. Like this globular star cluster, called M15, in our Galaxy. Image Credit: NASA and The Hubble Heritage Team (STScI/AURA)

  13. What do you think? What happens to a spaceship that falls into a black hole? Will the black holes in our Galaxy eventually suck up everything in it - a cosmic vacuum cleaner? What would happen to Earth if the Sun was replaced by a black hole of the same mass? If we can’t see black holes, how do we know they are there?

  19. How have we survived and avoided being ‘sucked up’ by a black hole? There are 200 billion stars in our galaxy, the Milky Way There are also millions of black holes Including one giant black hole at the very center. 15

Wisconsin/A.Barger et al.; Illustrations: NASA/CXC/M.Weiss NASA missions continue to search for and study black holes to determine the fate of matter as it falls into black holes, how powerful jets form, and what role black holes played in the formation of the early universe.
