Blacks holes...
What is a black hole?
Black holes are a large amount of matter packed tightly together
Scientist find black holes because they emit light. True or False
False
Black holes don’t reflect light making it invisible even to telescopes. Scientist primarily study them based on their surroundings and how it affects them.
Blacks hole have/ have not been observed as worm holes to different universes
Have not
Contrary to most people’s thoughts, black holes don’t provide shortcuts between different points in space or portals to other universes.
What is this effect?
The stretch of any object going into a black hole
Are blacks hole fully understood?
No, scientist don't fully understand them.
How do scientists identify black holes?
Gravitational Waves
When very massive objects speed through space they create ripples in the fabric of space-time called gravitational waves. Scientist detect these waves to determine if there is a black hole
Black Holes after formation start to remove matter around itself
False
Black holes don’t suck in other matter. From far enough away their gravitational effects or like those of other objects with the same mass
Mysterious or not?
Black holes are among the most mysterious cosmic objects mostly not fully understood.
Can scientist observe star patterns to identify black holes?
Yes
When a black hole is supermassive it’s intense gravity can cause stars to orbit around it in a particular way.
Black Holes form when stars collide????
Yes, some can but they can also form during a stars death
If the "Event Horizon" is the point of no return, this hypothetical boundary located further out marks the last place where light can still orbit a black hole without falling in
Photon Sphere
This boundary surrounding a black hole is known as the "point of no return" because not even light can escape its gravity.
The event horizon
Can black holes merge to form bigger black holes?
Yes, black holes can and do merge to create larger black holes, a process that is a primary way they grow, particularly when galaxies collide. When two black holes collide, they combine to form a single, more massive black hole, with the total area of the new event horizon larger than the initial two combined
What is at least one part of a black hole?
Photon Sphere and Acceleration Disk.
