The sun should not become a black hole. It does not have sufficient mass to undergo the necessary collapse.
Basically there is no "next stage". Well, it is believed that a black hole will evaporate, but that will take a long, long time.
Yes it is possible for Canis magoris to become a black hole, but at its current age it may either explode and turn into a dwarf star or implode and become a black hole. The process will take millions of year, but the possibility is there. But for a definite answer that is impossible at the current status of data. Their are just too many factors that could come into play.
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.
Neither. Our Sun will turn into a red giant, and then cool to become a white dwarf.
You get the shark to come near you and follow you to the black hole, then when you get to the black hole you turn a let the shark in. Have fun!
probably not long.My Answer:This is one of those questions that will depend on where you are observing from. If you are the one in a black hole and the most basic measure of time and death are used: Once you are in the Black hole your death would be instant.Traveling into the hole and dieing may take virtually forever because of the way a Black Hole distorts time and gravity.If you could figure out how to watch from out side no human could live long enough to see a person die and confirm that he/she was dead. Again this is due to distortion of time.
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.

If you were to get too close to a black hole, it would take a very short amount of time for it to kill you due to its intense gravitational pull. The exact time would depend on the size of the black hole and how close you are to it, but it could be a matter of seconds to minutes before you are pulled in and crushed.
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.
It depends on how much mass the black hole had. If the black hole had the mass of our Sun, it would take a long time, around a hundred million years. For a really big black hole, with a hundred million times the mass of our Sun (as is thought to exist in the centers of some galaxies), it would take about ten thousand years. One thing to remember is that at such great distances the gravity of a black hole acts like the gravity of anything else with that mass (e.g., if the Sun were magically turned into a black hole with the Sun's mass, the Earth would orbit as it always does. We'd just get cold without the Sun's radiation!). The weird effects you read about for black holes happen only very close in.
Yes! It is because time is relative, and so the process of getting sucked into a Black Hole will be long enough for you to live your life before your body begins to disintegrate. In fact, even right now you are in the process of getting sucked into a Black Hole at the center of our galaxy. But it will take millions and millions of years for you to reach the point where you enter the Hole. It purely depends on the intensity of the gravitational pull of the Black Hole. If it has infinite gravity, then it will take you infinite amount of time to reach it.
