Very Funny!!!

I went to visit the google news group and I pouted then giggled because I was amused the way some would make a post and some would make a laughable reply:

for example(click here to read these at the newsgroup),


According to theory, a black hole can still support it's outer
gravitational field, even though its escape velocity is faster than
light (and light-speed gravitons), on relic gravitation.


According to General Relativity, from an outside reference frame, a
black hole takes forever to form. So there will never be a time when
light-speed gravitons, forming the gravitational field, get trapped
inside the black hole.


But from the perspective of the black hole forming, or someone falling
into a black hole, everything takes place in a short amount of time,
and the outside universe rushes through an infinite amount of time in
a heartbeat.


So if virtual particles were to be split up by one of the pair falling
into the black hole and the other radiating away the mass of the black
hole, wouldn't that have to happen an infinite time in future after
the black hole forms?

Wrong. How can proper time go any faster than gravitational
time?
Try to show me and I'll show you a chicken with teeth.
It can't. Time for objects in gravity can only go slower than
the - curved - time of gravity not faster.
There is only one time which can have two dilations - one
by accelerating and the other by gravity.
It must be known that both dilations can never end time.

Thank you for your time.

Black hole is black and you can't see it.
When it evaporates, you can't see either, thus it is safe to say that black
hole
went there and evaporated, since you have no proof that it hadn't.
