is it possible for a black hole to pass the atmosphere and reach earth and suck random things in?

A star is stationary object and a black hole is a result of dying star. Black holes are stationary objects.
They posses a great gravitational force. It is so great that it can even suck in light.
Due to such gravitational force it makes objects near it to revolve around it with tremendous speed.

The closest black hole to earth lies just 1,600 light-years
(1 light year = 9.4605284 × 10^15 meters ) from Earth on the way to the centre of the Milky Way in the direction of the constellation Sagittarius.

But if you want to test the above facts and experience it yourself then just wait till sun becomes one black hole!!!! (after around 5-6 billion years) (Sun can also become neutron star or nebula so may be you cannot experience it!!)

Yes. Imagine the following scenario.

Black holes may exist in all sizes. Imagine that a visiting spaceship drops a tiny one, say one with a mass of a few thousand kilograms on the earth. The BH would plough through the atmosphere, accelerate and swallow air just before it. It would drop *into* the earth. It wouldn´t stop as, again, the mass before it would disappear into it.

The earth would effectively be transparant for our BH. So it would start to orbit around the center of the earth, all the time absorbing mass from the earth. The orbit radius would slowly become smaller and smaller and in the end the BH would settle in the earth´s core, eating iron.

Not much at first.

But steadily the BH would grow, become bigger by the mass it absorbed. Its gravitation would become larger too, permitting it to absorb mass at a faster rate. Faster and faster it would grow, eating up the earth from the inside.

At the surface we wouldn´t notice much. The total mass of earth plus BH would stay the same and the gravitation we feel would stay the same too. Maybe a few more earth quakes and more violent volcanic eruptions, would show that something was happening inside the earth.

But after a couple of years, the end would come fast. With the earth´s iron core disappeared into the BH, the outer layers would implode. The whole earth would break up and form another Asteroid Belt.

With the BH continuing its orbit around the sun in the middle of it.

Science Fiction? No.
In the laboratory this morning we had a power failure. The powerful electric trap that holds the black hole we were studying went off for a microsecond, before the emergency power took over. I still haven´t dared to explain the problem to my boss....

Nope.
(besides it being still a theory and never proven to exist)

To put it simple. Your question is the same as if you would ask if the sun could do this. A black hole is a HUGE thing as to its effect but small as to its size. It sucks in everything, it does not just select random stuff.

Like a star it is relatively in one spot in space.

But if earth was to be ripped from orbit and travelled toward a black hole (never mind that we'd be dead when that would happen) the whole earth would be accelerated to a speed where it would be ripped appart, squished to the size of a grain of sand and then sucked into that black hole.

The answer is an unequivocal "NO". Reasons are :-
1. The event horizon of the blackhole would make the first contact as it neared the earth. And at the event horizon time would stop as every thing would be tending to the speed of light.
2. So the Atmosphere would make first contact in each and every case.
3. The rest of the earth would follow like a streatched ball of chewing gum atom by atom starting with the mountains and the oceans.
4. An external observer would see every thing perched at the edge of the blue event horizon where it would remain till eternity since Time would have stopped.
A good question and sorrowfully - a negative answer - but it is good to see that we still have imagination to transcend the visible realities of life as we know it

I'm not sure why people think black holes don't move. Everything moves. There is no fixed position, so everything's motion and position is relative to other objects.

Someone also mentioned that they don't "suck" things in but pull them with their gravitational force. This is true. However, if you could sit it on the earth's surface, it would draw in air, resulting in a low pressure system that would cause wind moving towards it, basically sucking in anything light enough to be carried on that wind.

However, you would not be able to hold it on the surface. The most likely scenario is a high speed approach, burrowing through the earth and exiting the other side.

commonplace stellar-mass black holes are not to any extent further very desirable for this because they are too small and the tidal forces on the probe should be very tremendous. yet supermassive black holes, like the single on the middle of our galaxy, have a more suitable gently sloped gravitational container and there is not any reason a strongly equipped probe ought to no longer live on and proceed sending back functional information as a lot because the point the position it crossed the shape horizon. as quickly because it crosses the shape horizon there is not any authentic way interior of common physics for it to deliver a message that shall we receive, because each and every message should be curved back round into the black hollow earlier it ought to get out. The probe ought to quite live on for much previous the shape horizon, yet as quickly because it receives previous the shape horizon, it (like its messages) is doomed to in straightforward words bypass farther into the black hollow, and finally will attain a area the position the tidal forces exceed the structural ability of the probe and the probe is destroyed. also note even with the actuality that that products stepping right into a black hollow adventure time slowing down. both the transmitter on the probe or the receiver outside the black hollow (more suitable probably the latter) ought to consequently should be calibrated to account for this actuality, to make certain that the messages to be gained properly. It also means that from the attitude of the probe, something of the Universe ought to look transferring swifter because the probe fell extra into the black hollow, likely allowing the probe to live on lengthy sufficient to visual show unit the Universe replace into the far cosmological destiny.

A black hole is a cosmic vacuum cleaner. perhaps in 100 billion years the earth may be sucked into it...

Let's just hope it doesn't get the Dyson technology...

There was a documentary that addressed this once. For any decent sized black hole, you would be killed long befor it got to Earth

black holes really do not move but its super great force which came frm the centre of it causes it to suck in other things

Where do some of these people come from who post answers when they obviously don't know squat about the subject?

Go with CHUCKTAYLOR3US's answer. He da' man!

Black holes don't move? Ha! Ha! Ha! Ha! Ha!
