    It's that worm-thing from the Empire Strikes Back:

    Is our sun large enough to cause a black hole
    When it's done??????

    EDIT [The collapsed core of] our sun would have to be about 3X its mass in order for its own gravity to overcome the pressure of neutrons remaining in its core after collapsing:

    According to NASA no Our Sun is actually too small to end up as a black hole. It does not contain enough matter to exert that kind of gravitational force on itself. A star has to be more than about 10 times the mass of our Sun to become a black hole.

    Phew! Had me worried there for a minute. But if I'm at an event horizon, a minute will last a long time.

    As we know...
    This will go badly for me...

    Nice I like it :thumb:

    In the immediate environment of a black hole, where does time stop ticking if one were to follow a 'watch' falling into a black hole?

    1. At the event horizon?

    2. In the central singularity?
    If time stops at the event horizon, does the watch get stuck there, or does it keep falling in all the way to the singularity ?

    This way of explaining it may help Thom

    A black hole is any amount of matter squeezed into a very, very dense package.
    Imagine all of planet Earth squeezed into the size of a marble. Earth would then be a black hole!
    But, the gravitational pull of a black hole, or anything else for that matter, depends only on mass and distance, not how large or small the object is.
    Even you Thom could be a black hole if you were compressed to be more than one thousand billion billion times smaller than a grain of salt. But, you could still stand as close to me as you would for a normal conversation and you would not fall into the "Dr Stratster black hole, because you would exert no more gravitational force than you do now.

    If the Sun were somehow compressed enough to become a black hole, it would be less than 4 miles (well under 6 kilometres) across.
    It would exert no more gravitational force on Earth or the other planets in the solar system than it does now. Why? Because it would contain no more matter than it does now and it would be no closer to the planets than it is now.

    I think the question is invalid, since watches aren't synonymous with time.
