Assuming the star falls directly towards the black hole, it would cross the event horizon close to the speed of light. That means that if the "front" part of the star goes through the black hole, the "back" part will cross it a few seconds later, depending on the star's diameter. You can divide the diameter of the star by the speed of light - except that while approaching the black hole, the star might become elongated; this will make the time it takes a bit longer.

Can the sun form a black hole and take earth to another galaxy If yes how I no why not?
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.
How was the black whole discovered?
The idea of black holes was first proposed mathematically long before we found the first physical evidence of their existence. The earliest notion of a black hole was proposed in by John Michell in 1783 by John Michell who reasoned, based on Newtonian mechanics, that a star with an escape velocity grater than the speed of light may appear dark. The concept of a black hole based in general relativity, which is how we currently understand them, was proposed in 1916 by Karl Schwarzschild, but even then the idea was though of as a mere mathematical curiosity. Work done in the 1930s suggested that some stars may indeed collapse into black holes. The first likely black hole to be found was found in the Cygnus X-1 system, a binary system. The blue star in the system is pulled by the gravity of a very massive but compact object that emits extremely intense X-rays. Based on estimates of its size and mass, the only likely explanation is that the X_ray source is a black hole. The X-rays form as the black hole pulls in gas from the star. That gas becomes extremely hot as its spirals toward the black hole and emits powerful X-rays.
What is a small hot star that is near the end of its life called?
There are small hot stars - White dwarfs, neutron stars but by furtue that they are hot, means they are not near the end of their lives. It takes a long long time for all the residual heat to escape into the Universe. So, there are NO hot stars near the end of it's life.
What observational evidence do we have that black holes exist?
The universe doesn't have a center (at least its impossible to prove) but a light ''beam'' of 13 billion years was received by the Hubble, i came from a quasar and i was calculated that the black hole hiding there should be at least 100.000 light years long(like the milky way). So, some people think that it is pretty near of the ''big bang'' site because that light was like the same age of the universe, even if the ''big bang'' its a theory. There is a history to the "afters" of a Big Bang even if they were in the few seconds---or even the micronanoseconds. All applies and is important. Our divisions are sacrosanct. When you put a spot on an electron, and it takes two spins to come back to it's staring point, Houston, we have a problem. Physicists drive to Dark Matter and Dark Energy. But the answer is the Black Hole. Y'all super close.
How long do blackholes last in space?
That is a really good question, but no one actually knows. Though we do know that one day that Black holes will die because it will become smaller and smaller and then ping, it died. However the black holes that were create from the beginning of the Universe are still exist, so it will takes billions and billions and billions and billions of years from black hole to die.
How long would you survive in a black hole?
You would not; you wouldn't survive the tidal forces as you came near the black hole. Your atoms would fall into the event horizon, but your molecules would be destroyed before then.
Can you sleep in a black hole?
No. The gravitational forces are so great that your body would be ripped apart long before you actually entered the black hole.
What would happen if you jumped into a Kerr black hole?
If you jumped into an "ordinary" Schwarzschild black hole, you would be crushed into a long line of particles, which means death by a black hole. If you jumped into a Kerr black hole, the same process may occur, but the only thing different is that a Kerr black hole spins, and a Schwarzschild black hole does not. That answer needs a bit more detail. Please use the "related link" below.
What would traveling in a black hole be like?
Travelling into a black hole would be like an excruciating long death by torture, as the extreme gravitational forces compact and decompose the order of your mass.
Can you enter a black hole?
IF you had a very fast spaceship, it would be possible to fly it toward the black hole - but the spaceship AND YOU would be destroyed long before the molecular goo of your body entered the black hole. So, no. You can't get there, and you wouldn't want to even if you could.
What happends if humans enter a black hole?
They would die long before they reached it. The vicinity of a black hole is not a healthy place to be for a wide variety of reasons.
What happens at the edge of a black hole?
You are referring to the "event horizon" of a black hole. At this point, nothing, not even light, can escape the gravity of the singularity (or black hole). If you were so unlucky to be there, your body would be stretched from the part that is closest to the black hole. Eventually, your body would be one long string of atoms swirling into the black hole. This is called "spaghettification" and is an actual scientific term.
How do people get sucked into a black hole?
No human has ever come near a black hole. If one did, the intense gravitational pull of the black hole would pull them in and tear them to atoms, long before they reached the event horizon.
What will happen in TIME if you stay too long beside a black hole?
Scientists cannot be certain, as we have yet to experiment with a black hole, but they theorize that time would slow down relative to time far from the black hole.
How long will a black hole to turn on axis?
If a black hole has spin, it will spin forever.
Is a black hole strong enough to suck earth in?
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.
What happens to rockets that go in the black hole?
When a rocket gets too close to a black hole, it would experience a phenomenon called spaghettification. The immense gravitational pull of the black hole would stretch the rocket into long, thin strands like spaghetti, ultimately tearing it apart. The remains of the rocket would be sucked into the black hole, adding to its mass.
