What is a black hole
A place in space where matter is packed into a very small space.
100
Who wrote the theory of general relativity
Albert Einstein
100
When does a black hole form?
When a star reaches the end of its life and collapses in on itself
100
Do white holes exist for sure or are they theoretical?
Theoretical
100
Can scientists study black using traditional space technology?
No, we can't see them using traditional space research technology
200
In a black hole, ____ is so strong that not even ___ can escape
gravity, light
200
Give an example of the Geodetic Effect
If there is a bowling ball on a trampoline, marble rolling across the trampoline will be attracted to the bowling ball
200
What is a star and how does it form?
A star is a massive collection of mostly hydrogen atoms and they’re formed when large, dense clouds of gas and dust collapse in on themselves due to their gravity.
200
What is a white hole?
A cosmic object which is very bright and spews things out; the exact opposite of a black hole.
200
What is a spectroscope?
A device that measures the spectrum of light
300
How can a star ten times the mass of our sun become a black hole?
If condensed to a space about the diameter of New York City.
300
Who created the mathematical model to explain “the point of no return”
Karl Schwarzschild
300
What are the 3 types of black holes in size order?
stellar, intermediate, supermassive
300
What is the name of the black hole at the centre of the milky way?
Saggitarius A
300
How are black holes studied right now?
By studying the celestial bodies near a blackhole and the effects of the black hole on the celestial bodies
400
What is spaghettification?
when something is stretched into long thin shapes by a non-homogeneous gravitational field.
400
Summarize the theory of general relativity
Gravity is a distortion in the fabric of space and time and is caused by large masses.
400
What is the process that takes place in the center of stars?
nuclear fusion crushes the hydrogen atoms into helium in the core
400
How far is the closest confirmed black hole to Earth?
1500 light-years
400
What do black holes emit as they pull in matter?
heat/ x-rays
500
Name these parts of the black hole
1. Ergosphere
2. Event horizon
3. Singularity
500
Astrophysicist John Archibald Wheeler summarized and said: “___ tells ___ how to curve, and ____ tells ___ how to move."
matter, space-time, space-time, matter
500
The fusion process of ___ does not create any energy so as it builds up in the core of a star, the delicate balance between the ____ and ____ is broken
iron, radiation, gravity
500
What are wormholes, and what are the entry and exit points?
A tunnel through space and time, black holes are the entry point and white holes are the exit
500
Why should we study black holes?
The concept of a singularity helps us understand and envision the creation of the universe
