Quality of Questions?

Question

now a days people are asking Q about these ufo's and new planets and some weird Q .the Quality of Q is very bad..what do u ppl think?
and my Q is...
if our Sun was magically crushed until it was about 1 mile in size, it would become a black hole, so will the Earth remain in its same orbit???

also explain it...

im getting answers that sun will not be a black hole...
i said its MAGICALLY CRUSHED until it was 1mile in size.. so.. there is no change of mass there

Answer 1

There are a lot of kids in this place. Don't expect too much. Let them fantasize about the world and ask silly questions.

As long as the gravitational field/force does not change, and i don't think it will change at all since the conservation of matter still holds. In short, Earth remain the same orbit.

But things will change if the black hole sucked in more matters and changes it's gravitational force significantly,

Answer 2

The general quality of questions (and answers) is very poor, to put it mildly. There are far too many outright stupid questions that either make no sense, ask the same things over and over, or that folks could have figured out more quickly (and accurately) by searching google.

As for magically crushing the sun to just a mile in diameter...that is too small for a white dwarf and would put it in the realm of a neutron star (though it's still a bit smaller than a neutron star of that mass would be). On the other hand, it's much too large a diameter to create a black hole. And, yes, if the mass remained the same, all the planets would orbit just as they do now.

Answer 3

The sun wouldn't become a black hole if it were crushed into 1-mile in size, it would become a cool dwarf of some kind (white dwarf, etc.) A black hole requires more material than the sun currently has in order to produce a gravitational effect of that type. The earth's orbit shouldn't be affected.

Answer 4

Our sun doesn't have enough mass to become a black hole..... as a matter fo fact, the type of star you describe is called a white dwarf. That will be the fate of our sun.

As to the quality of questions, there are kids here and they are intrested enough to ask questions. We should not discourage them.








Except for the Uranus jokes. I hate those.

Answer 5

yes the quality of questions are bad. On your second question I have no idea but I am going to guess, earth would not stay in the same orbit.

Answer 6

Hmm... I would definitely think that the Earth's orbit would be maintained, as there would be no impetus for change. Of course, we humans would still be screwed, as things would get mighty cold around here.
