Some red supergiants (have to have 3x the matter of the sun), and all hypergiants end their lives as a black hole.

What is the name of the continuum formed by space and time?
Space-time

What is the astronomical definition of a black hole?
A black hole is a region of spacetime with such strong gravitational forces that nothing can escape it.
200
What are the three types of black holes?
Stellar, supermassive, and miniature
200
When a star becomes a black hole, does it get smaller or larger?
Smaller - all the gravitational pressure compresses into one small space.
200
What causes a distortion in space-time?
Massive objects
200
What is a supernova?
A star that significantly increases brightness due to a large explosion that ejects most of its mass.
300
What is the black hole produced by stars?
A stellar black hole.
300
How is a stellar black hole formed?
A black hole is formed when the center of a massive star collapses onto itself, because it cannot hold its weight.
300
What is the name of the phenomenon caused by gravity bending light?
Gravitational Lensing
300
What is the Singularity?
The squashed up star, where all the gravity is located.
400
What black hole has never been discovered?
A miniature black hole.
400
Is a black hole invisible, and does it make noise?
Black holes are invisible, and are silent.
400
Can events that occur at one time for an observer occur at another time for another observer?
Yes, because of the distortion of space-time.
400
Where is the Singularity located?
The center of the black hole.
500
What is the average mass of a supermassive black hole, and where are they usually located?
A supermassive black hole is normally found in the center of galaxy, and can have a mass of billions of suns.
500
What are the three parts of a black hole?
Outer Event Horizon, Inner Event Horizon, and the Singularity.
500
What does Einstein's theory of general relativity state?
This theory stated that the laws of physics are the same for all non-accelerating observers; the speed of light in a vacuum was independent of the motion of all observers, and all objects move relative to each other.

If you were sucked into a black hole, what part could you escape from?
