eNathan said:I think we are both on the same page here. Yes, my equation does not describe anything physical. But, if you look at a graph of time dilation, you can almost predict or assume (logical) that if v > c then -t. But I have not taken any courses on relativity (although I want to), and all of my studies are straight from the NET. And the NET has some very innacurate and misleading statements therein.
You keep doing exactly what we tell you not to do. You are graphing a function that has a physical meaning, and then changing the function and trying to interpret the physical meaning of the new function. Theres a reason the absolute value sign isn't in there.
IF
f(x) = \sqrt{|1-\frac{x^2}{k}|} AND x^2 > k
THEN f(x) would be negative. This is 100% correct. Thsi is as far as you can take your problem without starting to **** with relativity theories.
