What is a blackhole?
Stellar black holes form when the center of a very massive star collapses in upon itself.
This collapse also causes a supernova, or an exploding star, that blasts part of the star into space.
Scientists think supermassive black holes are formed at the same time as the galaxy in which they are in.
Biggest Blackhole in the Universe!
Scientists discovered that the biggest blackhole is about 250 million light-years from Earth.
The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277.
Basic Premise of Modern Physics
If something falls into a blackhole, it cannot be contacted back. Its future can't be predicted.
No observer could practically survive once they travel to black hole.
Blackholes threaten to bust the trap!
If you shine a white light at an astronaut falling toward the event horizon, that time dilation will — from that astronaut's perspective — cause the light to appear to change.
