Re: Most distant event ever observed
If you are on the sphere Chris talks about there is still a center of the sphere that is the center all points on the sphere.

Most distand GRB
Can the location of the most distant GRB tell us the direction of where the Big Bang occurred?

Re: Escape velocity from a black hole
Yet Chris Petersen has reminded me that there are collectors being built to detect gravity waves. Maybe what gravity is shaping is only part of what exists in space like the meduim that carrys elcetro magnetic waves. Possibly there is more to space than what light interacts with and maybe gravity do...

Re: Speed of Gravity
Less than the diameter of the space the wave like particles a proton is made of occupy! Less than the diameter the space an elusive graviton exists in? Once we slice up a quark we might find the diameter of a protom to be very large relatively. A photon propagates though a medium in space that has e...

Re: Speed of Gravity
Well said! Then gravity takes a long time to propagate across the universe. We can see light waves even though they travel at that speed but we can't see gravity waves. I wonder what gravity waves disturb that we can see?

Escape velocity from a black hole
I am an artist and not a physicicst so please don't take my comments literally because I only seek to stimulate thought in the minds of those who have the knowledge it will take to know the reality, so I ask if the escape velocity from a black hole is greater than the velocity of light then gravity ...

Re: Speed of Gravity
Thanks! I appreciate your answer. I just imagined large masses beyond our view, possibly outside the area encompased by the big bang, affecting our universe and us not knowing it.

Re: Speed of Gravity
Not being a phyiscist I ask...What If there is a very hugh mass very far to the right of us and very hugh mass very far to the left of us both so far away that we see no light and have no idea they are there, yet these two sources would have a center of gravity nearby. What would the characteristics...

Re: Speed of Gravity
I am wondering if approaching theoretical cosmology in a artistic way might inspire the true physicist to think in a different way long enough to extend the boundry of knowledge so to see things in a different light...not the light measure in terms of velocity but the light Einstein saw when he had ...

Speed of Gravity
I submit that may actually gravity travel faster than the speed of light. I have read that gravity might even be instanteous so when an event affecting gravity happend on the other side of the universe this side feels the affects at the same time. I read that even Einstein did not fully understand g...

gravity and black hole shadow
I submit for consideration that possibly gravity might propagate at the speed of light squared as is suggested in e=mcc. Further, I inquire if a blackhole would cast a shadow? No answer required...think about it.
