No. The boundary of a black hole is called the “event horizon,” and it has a limited extent. The gravity of a black hole is the same as a normal object, except that it’s usually a lot because most black holes are very dense. As long as you’re outside the event horizon, you can avoid getting sucked in. If you’re inside the event horizon, however, you’re doomed.
As more matter passes the event horizon and gets pulled into the black hole, the density increases, so could the radius of the event horizon increase, resulting in a black hole expanding further and futher? Or is the radius of the event horizon only based on the original mass of the star that became the black hole?

Are we inside the event horizon?
Sean commented on :
No, the event horizon is the area of no return. Once inside the event horizon, even light can’t escape. This is what makes the black hole ‘black’.

What if your close to it?xx
Sean commented on :
then it will be possible to escape if you have enough velocity. So it depends on how fast your spaceship is 🙂
