Neptune does not have a black hole
The black hole at the centre of the Andromeda galaxy is estimated to be 140 million Solar-masses.
After a black hole
The big hole is apparently the giant chasm where you find a level 75 Kyurem.
Well if your comparing the smallest black hole knowen to humans to the Earth YES THEY ARE BIG but there is no definant diameter or size considering that all black holes are unique in all three size diameter and gravataional pull.
Assuming you mean the event horizon of a black hole (there are other types as well), the diameter of a black hole as measured by its event horizon is directly proportional to its mass. The larger the mass, the larger the diameter. Thus, as a black hole's mass increases, it will get bigger. The only limitation is how much mass a black hole is able to incorporate from its surroundings.
No. No black hole is big enough to do that.
Actually one interpretation of the big bang is as a white hole, the inverse of a black hole.
A black hole can,but it is very rare for a black hole big enough to swallow Earth.
It is black!!
both of the black hole will join together as one big black hole. they can either have a direct hit or both spin, twirling into each other until it create a new super big black hole.
No. The Big Bang was an event, not a material thing. (There are plenty of other ways in which it is utterly unlike a black hole as well.)
no black holes are stars
scientists think that the Big Bang which generated the univerese waas the consequence of the explosion of a massive black hole. so the big bang
No, it is a storm, similar to the Great Red Spot on Jupiter.
YES
NO BIG NO
