Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

True/False: If you fell into a black hole, you would be stretched out like a piece of spaghetti, and time & space would change for you.
True-This is called Spaghettification
True/False: We have a possible Black Hole in our Solar System.
True-It is currently called “planet 9” because scientists don’t know for sure if it is a black hole or another planet.
What is the name of the Black Hole at the center of our Milky Way Galaxy?
Sagittarius A
True/False: There are about 125 billion galaxies in the observable universe & it is believed most of these have supermassive black holes in the center of them.
True
True/False: Our galaxy, the Milky Way, has about 1,000 black holes.
False-There are between 10 million to 1 billion Black Holes in our Galaxy.
True/False: The Beautiful Horizon Telescope was the first to get a true image of a black hole.
False-the Event Horizon Telescope
True/False: We can detect or find black holes if we see a big black area in space.
False-we cannot see the singularity or the event horizon, so we must watch for the matter & how it is reacting to the black hole or how the stars are reacting.
True/False: We can detect or find black holes by watching how the stars orbit.
True
Which type of black hole is usually found at the center of most galaxies, and might be made when a cluster of stellar black holes merge together?
Supermassive black holes
Which type of black hole is known for being super small & even though it is very heavy, can actually be the size of a hair?
Mini or Macro Black Holes
How do scientists think an Intermediate black hole is formed?
Two black holes merge together, or collide to form a larger one usually 100 to 1,000 times the mass of the Sun.
Which type of black hole is formed when a star dies & range from about 5 to 60 solar masses?
Stellar Black Holes
What are the different types of black holes dependent on?
Weight or Mass
True/False: One way a black hole forms is when a large star dies.
True
True/False: The Relativistic jet is the center of a black hole where matter collapses.
False-They are jets of particles & radiation that blast out near light speed as a star is absorbed by a black hole.
True/False: The Accretion disc is superheated gas & dust whirling around a black hole that create x-rays (electromagnetic radiation).
True
What is the bright ring around the event horizon called which is caused by all the matter swirling around, getting hotter and hotter & turning into light?
Photon Sphere
What is the area around a singularity called where matter or energy can escape from-The Point of No Return
The Event Horizon
What is a Singularity?
The center of a black hole where matter collapses
Why is the gravity so strong at the center (singularity) of a Black Hole?
Because all matter is being pulled in to such a small area so the gravity become super-intense.
What is a Black Hole?
A place in space where gravity pulls so much that even light can not get out or escape.
