: : Can someone tell me explain the following question for me ? : : If say a large spinning sun 50 million miles wide was to implode and thus : : form a black hole, one could assume that the rotational speed of the imploded sun would : : increase due to the decreased diameter of the now imploded sun and hence the inertial force acting : : on this object trying to throw it apart would be very much greater as a black hole now spinning at very high velocity : : however the gravitatonal force's would also be much ,much greater. One could expect these forces to operate in against each other : : and hence cancel out to some degree. How therefore does the black hole stay in a stable form.

: : Is this a fair and reasonable question and theory to put forward. I am not a scientist but understand the basic laws of matter and and : : physics.

: : If anyone can answer my question please e-mail me the answeron: : : jaspooner@mcmail.com

: :: A blac hole is literally a sun (star) that has imploded, and its whole initial mass is compressed into "zero-space." If an object is in zero space, how can it not be stable?

Well, if there is a such thing as "Hawkings radation" then a black hole with a mass "just" large enough to become a black hole could explode again, if the mass of the "star" were reduced enough by Hawkings radation.

: :: There is noway for it to become unstable, because there is nowhere else for it to go.
