What is strange about black holes?
Black holes are perhaps the most nightmarishly fascinating features of our universe. Like long dark tunnels to nowhere (or giant garbage disposals), these mysterious fixtures in space exert a gravitational pull so gripping that nothing close by — not even light — can escape from being swallowed.
What are 3 interesting facts about black holes?
10 Fun Facts About Black Holes
- You Can’t Directly See a Black Hole.
- Our Milky Way Probably Has a Black Hole.
- Dying Stars Lead to Stellar Black Holes.
- There are Three Categories of Black Holes.
- Black Holes Are Funky.
- The First Black Hole Wasn’t Discovered Until X-Ray Astronomy was Used.
Does it hurt when you fall into a black hole?
When you start feeling pain depends on the size of the black hole. If you’re falling into a stellar black hole, you’ll start feeling uncomfortable within 6,000 kilometers (3,728 miles) of the center, long before you cross the horizon [source: Bunn]. Either way, spaghettification leads to a painful conclusion.
Can we survive a black hole?
Basically, it could be theoretically possible (but probably not very likely) to survive a trip into a massive black hole, and some scientists predict some forms of alien life might even live inside the Cauchy horizon. However, you should say goodbye to everyone you know and love, because this move is permanent.
What is the most frightening fact about black holes?
Black holes are perhaps the most interesting and terrifying objects in the Universe, despite us not really knowing much about them. They most commonly occur from the collapse of a massive star when the core runs out of fuel to ignite the star, collapses, and the outerlayer explodes in a phenomena known as a “supernova” blast.
What is known so far about black holes?
The closest known black holes are stellar mass black holes in our galaxy. These black holes have so far only been seen when they are in close contact with another star which is orbiting around them (well really they orbit each other). The black hole accretes material from the star and this produces a lot of energy.
What are some famous black holes?
Famous Black Holes. Cygnus X-1: a stellar-mass black hole and x-ray source that lies some 6,500 light-years away. It is a binary system that contains a blue supergiant variable star and the x-ray source thought to be the black hole. Sagittarius A*: the supermassive black hole at the heart of the Milky Way Galaxy.
What is the most massive black hole in the universe?
Astronomers have discovered what may be the most massive black hole ever known in a small galaxy about 250 million light-years from Earth, scientists say. The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277 in the constellation Perseus.
