OK, I just made a few very basic calculations to find out the gravitational acceleration of black holes - BASED on our humble observations so far about black holes. You know mathematics(and physics) is many times counterintuitive(that said: you are surprised when you see the result...) - but this time my intuition told me that the speed of attraction...or just the gravitational acceleration of a black hole will be so fast than...you are right...it appears ot be much faster than the speed of light. In fact, even if our assumptions of radius and mass of a black hole are with >100% margin of error - it still appears that the g of a black hole will be fairly high. That said - it appeared in some of the variables I used that sometimes the speed will be thousands of times faster than the speed of light. So...there are many conclusions to be made here.
But basically, it's not even this interesting observational fact which irritates me - it's obvious that even if our black hole observations are really erronous - then still a speed of 0.9999 of the speed of light will be interesting from the point of view that at least time traveling to the future will be possible. What's interesting is the question: what THE HELL happens when the speed is faster?
Based on how Einstein has formulated the time dilation equations - it appears if the speed = c -> you get "complex infinity" and when the speed is faster...you get imaginary number.
For instance, if you try to explain this logically - it means that a time traveller in a machine moving with velocity = c - will literally go infinite amount of time ahead in the future? And...if the velocity is faster - then I can't even come up with a "crazy hypothesis" as to what might happen.
So...the interesting point of time dilation is that it's a "typical Einstein problem" - so to speak, it's relatively(what a word...) easy to be calculated - but almost impossible to be understood logically. The equations used in the time dilation principle - are so basic that even won't surprise any math wizard - but the logic...it's irritating. I can go as far as using vector calculus or writing c++ programs to express the problem here...but that's not the point - the logic will always be the same: It can't be explained what happens when an object is moving faster than the speed of light.
Any logical suggestions will be appreciated.
thanks
