@9th Wave I must confess that i believe iam one of those humans who possess the necessary requirements for Time-Travel, and i agree with you regarding the problems of changing my time-line for example, and also other time-lines that i might visit...Of course i have ideas that i hope would be useful in negating "some" of those problems..

..
By the way, you produced an interesting posting..
Thank you.
I also think that, within the boundaries of what we believe to be time, in which doesn't technically exist.
There is what they call the "mirror-effect", the alternate matrix-grid for multiple universal timelines in the void.
The void itself bends gravity, so is the will of planetary revolve.
An orbit is only as powerful as the matter it sustains around it's momentum, therefor so would be the alteration of mass & matter in the will to bend gravity.
It's possibly the reason why einstein was only partially correct within his theories.
Therefor, gravity itself is only a figment of the void momentum, rather than light speed itself.
