  • Cygnus X-1 was the first black hole discovered in 1964
  • Located within the Milky Way
    • In the constellation of Cygnus (the Swan)
  • Astronomers saw the first signs of the black hole when a sounding rocket detected celestial sources of X-rays 
  •  In 1971,  determined that the X-rays were coming from a bright blue star orbiting a strange dark object
  • Suggested the X-rays were a result of stellar material being pulled away from the bright star and "gobbled" up by the dark object; an all-consuming black hole.

  • 1915: Albert Einstein proposed his groundbreaking theory of General Relativity
    • The theory states, "any mass which falls within that radius would be unable to escape"
  • WWII:  Great discoveries were made but unconsidered due to the war and lack of proof
  • 1963: Princeton University physicist John Wheeler officially shared black bodies as ‘black holes.’
  • 1964: First black hole was discovered 
  • 2023: Only a dozen black holes have been discovered, the nearest one is 1,600 light-years away 
    • There are about 100 billion galaxies "close" to the region visible to Earth, and each galaxy has about 100 million stellar-mass black holes

  • Astronomers recently discovered massive black holes in the universe’s tiniest galaxies
  • And black holes wandering at their galaxies’ edges
  •  As galaxies grow, they collide and merge over time
    • "Feed" on new stars, gas, and dust particles
  • Of about 25,000 dwarf galaxies, 151 of them appeared to have big black holes
  • "Baby universes" can thus form within these massive black holes

    • A tunnel between two distant points in our universe that cuts the travel time from one point to the other
      • Using a wormhole could theoretically reduce travel time between galaxies from millions of years to hours or minutes
    Wormholes Create Bridges
    • A wormhole could be created within a black hole
    • A wormhole leads to an entirely separate universe
    • Could be the explanation for how to travel in a black hole

    • Located in space
    • Gravity is extremely strong, causing matter and light to be trapped
    • Forms when a massive star "dies" or collapses under its own gravitational pull
    • Pull is so intense that nothing can escape from it
    • Different sizes

    1. You can't see a black hole
    • Not even light can escape a black hole
    • Scientists detect their presence based on the effects of gravitational force 
    2. Two black holes can merge with each other to get larger
    • Their centers will merge into an even greater black hole
    • In about 4.5 billion years, black holes in our galaxy will merge with the Andromeda galaxy
    3. Time slows down near a black hole
    • The strong gravitational pull of the black hole moves so fast that it slows down time itself
    4. Black holes have 3 layers
    • Outer layer: gravitational pull isn’t strong
    • Inner layer: gravitational pull is so strong that not even light can escape from it
    • Singularity (the center): has the strongest gravitational pull
    5. Largest black hole is found in the center of the galaxy 
    • Milky Way: Saggitaruis A
      • A supermassive black hole at the center 
    • Andromeda: Has a supermassive black hole at its center
