A black hole near Neptune -- or near any other object in space -- would suck up that planet (or that object).
Fortunately, there nearest black hole to our Solar System is several thousand light years away.
There are hypotheses about so called 'virtual particles' that may travel faster than speed of light, and hence are not sucked up by Black Holes. Also, Black Holes cannot suck another bigger Black Hole, when they meet a bigger one, they get sucked up rather.
First of all, every black hole has the same size ... its length, width, height, radius, depth, diameter, area, and volume are all zero. What varies from one black hole to another is their mass. Next, black holes don't reach out and grab things that happen to be passing by. Outside of the hole's "event horizon" it has the same influence as any other object with the same mass. Other bodies that pass a black hole at a distance at which they're moving slower than escape velocity will settle into orbit around the hole.
White holes are theoretical regions of spacetime that expel matter and energy outward, the opposite of black holes which pull matter in. They do not suck up objects like black holes do. However, there is no observational evidence for the existence of white holes in the universe.
I am not sure what a "you stas" is. If you mean "stars", a black hole can indeed gobble up an entire star, if it gets close enough. Please note that we are in no immediate danger; the closest known black hole is at a distance of about 3000 light-years; but even a regular black hole at the distance of Alpha Centauri would pose no danger.
A black hole isn't a hole in the sense that it is a "drain" that funnels things out of the universe. Think of it more as a trash compactor. Everything a black hole sucks in contributes to the mass of the black hole and sits there at a impossibly small focus called a singularity. However, with the evidence of hawking radiation, (small particles that escape a black hole's event horizon periodically). It is now understoon that black holes have a "memory" of everything they've eaten. For example, if a black hole were to suck you up, your matter wouldn't disappear. Over the course of trillions of years, you would be spat out, particle by particle. So black holes will increase in density until there is nothing left to suck up around them, and then in an incredibly slow process (trillions and trillions of years) a black hole will lose density particle at a time until it is completely evaporated!
In theory, yes, a black hole could suck up the sun.
Yes, all black holes 'suck stuff up'.
A black hole will "suck things up" for the same reason that the Sun, or Jupiter, or Earth, "suck things up", although I would prefer the term "attracts things gravitationally". All those objects attract things thanks to their gravitational attraction - this, in turn, is related to its mass, i.e., more massive objects have a larger gravitational attraction.
yes, yes it can
It maters what way its going anyway it can suck up Jupiter or even mars and still might not effect earth but i can suck in planets and come for earth.
Since whit holes only exist mathematically, a black hole could not pull in a white hole.
Yes, it is possible for a black hole to capture another one and "swallow" it.
If it could have we wouldn't be alive NOW.
A black hole will attract you through its gravity - just like any other object will.
A black hole will suck you up in to a long piece. You will be stretch like spaghetti then be crushed.
Fortunately, no.
Black holes are basically highly compressed massive (has lots of mass) parts of space. The large amount of mass warps the space time around the black hole which causes intense gravity that suck everything in.
