:O I think I get it! I am genuinely trying to understand the concept, so please correct me if I'm wrong.
Is this theory comparable to X/50 = 100/Y? Bear with me.
X 100
____ = _____
50 Y
Mathematically, 5,000 = XY. So if X were 100, Y would be 50, because 5,000/100 = 50
100 100
____ = _____
50 50
Now if X went down to 25, Y would have to be 200.
25 100
____ = _____
50 200
And because there are four dimensions, the formula applies to spacetime. The Constants of spacial mass and the speed of light will never change, so the only things that change are velocity and time. They are inversely proportionate as X and Y are, so when one goes up, the other must go down.
Am I close? If I'm not, please notice that I'm making a sincere effort here.
NOTE: I got all this from Mr. Ireland's statement, not Engineer's picture.
