Plenty of them.
A black hole can,but it is very rare for a black hole big enough to swallow Earth.
The effect of a hole on a paper airplane would depend on the type of paper airplane the hole is on, and where it is on the aircraft.
If the Earth were inside a black hole, it would appear much smaller due to the extreme gravitational forces bending light.
For all scientific reasons, no astronaut had went inside a black hole. It would take many earth years to visit the black hole, so reaching a black hole is impossible.
I think you're referring to the little hole found near the bottom of the window. The window is actually made up of three panes. The inside middle plan has the hole in it, and the reason is equalize pressure on both sides.
Dig a hole, place your head in said hole, cover up hole.
Sure, Earth has caves for example. But presumably you mean deep inside. That's not really possible, at least, not in a large planet such as Earth, since such a hole would quickly collapse due to the immense pressure of the material above it.
Simply put, there are no black holes close enough to pull earth in.If you mean, why doesn't earth collapse into a black hole, the repulsion between the atoms that make up earth is strong enough to resist gravity in that regard.
No. The sun does not have enough mass to form a black hole. A black hole does not lead to another galaxy. Anything pulled into a black hole becomes part of that black hole's mass. Even then, if Earth were to fall into a black hole the same mass as the sun it would be torn apart by tidal forces long before it crossed the event horizon.
Since the nearest black hole is many light years away from Earth, it's impossible for a scientist to physically travel to a black hole to study it. Instead, they have to make do with observing the effects of black holes from Earth.
No, Earth will not fall into the black hole at the center of the Milky Way Galaxy. The black hole is located about 26,000 light-years away from Earth, and our solar system is orbiting it at a safe distance. The gravitational pull from the black hole is not strong enough to pull Earth into it.
If a black hole came close to our Earth, it would most definitely suck it in. But we wouldn't have much to worry about, since the x-rays radiating from the accretion disk surrounding a black hole would kill all life on our planet long before the black hole got here.
