Well, friend, everything in our world has its place and purpose, just like our feelings. While black holes are incredibly powerful and mysterious, fear and negativity can hold even more power over us. Remember, there's always light in the darkness, and overcoming our fears can lead to beautiful new paths in life.

What 2 things can happen to a star after a supernova?
It can either become a neutron star or a black hole. If the star is between 8 and 15 solar masses, it will become an incredibly dense neutron star. If it is more than 15 solar masses, it will collapse and become an even denser black hole.
How big does a star have to be in order to form a black hole?
Well, isn't that fascinating? Now, when a star has used up all its nuclear fuel and its core collapses under gravity, if the remnant is about 3 times more massive than our own Sun, it can become a black hole. Nature is full of these incredible, beautiful mysteries - just like happy little accidents waiting to be discovered.
Will Betelgeuse become a neutron star?
After a supernova explosion in Betelgeuse it will definitely become at least a neutron star. However, because of it's mass it's more than likely to become a black hole. If it does, then it will be the closest black hole to Earth.
What is the final stage for stars whose final masses are greater than three times the mass of the sun?
Stars more than about 3 times the mass of the sun are likely to wind up as neutron stars. Stars more than about 10 times the mass of the sun will probably end up as black holes.
What is left behind after a star with four or more stellar masses has died?
After a star with four or more stellar masses has died, it can result in a supernova explosion, leaving behind a dense core known as a neutron star or in some cases, the collapse can be so extreme that it forms a black hole.
What is more dangerous a black hole or a dark hole?
A black hole is more dangerous than a dark hole. Black holes are regions in space with gravitational forces so strong that not even light can escape, while a dark hole does not have a specific scientific definition and may refer to areas of space with lower light or energy levels.
Is a koala bear more dangerous than a black bear?
No. Black bears are far more dangerous.
How many people know's that we're getting closer to a black hole?
This is nothing to worry about. There are other, much more immediate, dangers to mankind. The closest known black hole is at a distance of about 3000 light-years, and even if there were a black hole at a distance of the nearest star (ca. 4 light-years), it wouldn't be any more dangerous than the stars themselves.
Is a neutron star or a black hole bigger?
A black hole has more mass than a neutron star, but if you are comparing volume it would depend on the mass of the black hole. A neutron star is estimated to be about 14 miles in diameter, which is larger than the event horizon of a black hole up to about 3.8 times the mass of the sun. A more massive black hole will be larger.
Could you survive a black hole if you were in something more dense than the black hole so you wouldn't get crushed?
there is no such thing as that
Which celestial body would have more thermal energy: the moon or a black hole?
A black hole would have more thermal energy than the moon.
Are black holes the strongest object in space?
That depends exactly how you interpret the term "strong". In its vicinity, the black hole distorts space more than anything that is NOT a black hole; so much that nothing can get out of the black hole. But at some standard distance, a galaxy, for example, would have more gravitational attraction than a black hole, simply because it has more mass. At least, so far no black hole of the mass of an entire galaxy has been found.That depends exactly how you interpret the term "strong".

Is there a possibility the sun could go super nova or turn into a black hole?
No. Our Sun isn't massive enough to go supernova, or to turn into a black hole. A star needs to be more than 3 times more massive than our Sun in order to become a black hole.
Is a black hole faster than light?
No, a black hole is not faster than light.
Why do you think an ozone hole in the Northern Stratosphere is more dangerous than one located above Antarctica?
Ozone hole over Northern Stratosphere is dangerous. It is because it is present over human race.
Is a black hole bigger than galaxy?
No. At least, the black holes in existence so far are much smaller in size, and have much less mass, than a galaxy. However, note that the black hole in the center of the largest galaxies can have more mass (but not more diameter) than some dwarf galaxies.
Is a black hole more powerful than the sun?
It depends on the circumstances. A black hole that is actively feeding can emit more energy than the sun as matter becomes superheated before falling into it. A feeding supermassive black hole forms a quasar, which can emit more energy in a single second than the sun will in its entire 10 billion years. However, if a black hole is not feeding then the only energy it gives off is Hawking radiation, which is so slight that we would not be able to detect it, even at close range. The gravity of a black hole is far stronger than that of the sun.
