It wasn't until 380,000 years after the Big Bang that the universe became transparent enough to let the light shine through it.
37. A black hole 12 billion light years away holds at least 140 trillion times the water in all of Earth's oceans combined, making it the largest known reservoir of water.
38. If you shout or make a sound that is 1,100 dB, it will create a black hole destroying our galaxy.
39. Stephen Hawking had to purchase a one-year subscription to Penthouse for Kip Thorne after losing a bet pertaining to the existence of black holes.

S5 0014+81, the biggest supermassive black hole known, is so bright due to its huge event horizon that if it were 100 light years away from Earth (6.31 billion times more distant than the Sun), it would appear just as bright as our host star.

43. Leonard Susskind, the professor of Theoretical physics, sparked a 28-year-old debate with Stephen Hawking, who stated that the information inside a black hole is lost forever, but eventually, Susskind proved him wrong.
44. The Schwarzschild Radius is the size an object is compressed in order to make it a black hole. Earth's Schwarzschild Radius would be compressing it to 8.7 mm, which is roughly the size of a peanut.
45. Supermassive Black Holes in the centers of galaxies can be 11 times bigger than Neptune's entire orbit, and spin at almost the speed of light.
