Information from a Black Hole
Discussion
It occurred to me that it may be incorrect that no information is released from a Black Hole (Except Hawking radiation)...What about Gravity itself?...If a large enough object was absorbed into the Black Hole it would have a measurable effect on the gravitational waves emanating from the Black Hole itself, allowing us some insight into what happens on the other side of the event horizon?
I.E: If the gravitational pull is a product of the mass creating it so I would presume that the change in gravity (from the increased mass) should be measurable from outside the event horizon, thus allowing information to escape the black hole (something I believe was thought to be impossible (Or at least was last time I looked into it!)...
If the gravitational pull of the black hole and the soon to be engulfed star were measured together it would be interesting to see if the net gravitational pull stayed the same after it entered the event horizon or perhaps even diminished.(Does the star remain as part of our universe or not?)

Posted this is another topic but can fit in here as well...
Thanks...no worries.....
Here is my idea...There are two travellers...one is going to enter the black hole (1) while the other (2) watches from outside...The first one has a futuristic device that can instantly make a black hole..(don't worry...this is a thought experiment...I just need the traveller to be able to cause a gravity wave)..as traveller 1 enters the black hole he sets of the device which instantly creates a gravity wave that will be felt by traveller 2 however from traveller 2's perspective traveller 1 is still falling into the black hole (time slows down as observed by traveller 2)...therefore gravity itself is moving backwards through time as seen by traveller 2....the gravity waves are felt before they see traveller 1 set of the device..In the real world (but way in the future) it could be a way of sending a probe into a black hole that could communicate to the outside world using gravitational waves....
Hope that makes sense..!

If gravitons exist (I don't think they do)...then they may travel at the speed of light but would not be bound by lights inability to escape gravity...an event that happens right on the edge of a black hole may take a week to be visible (due to gravity slowing time) but would appear instantaneous when measured by gravity wave...so again gravity travels backwards through an event...
