Right, Wastoute... but go further, or else you’ll leave Roccus thinking it’s all simply bulls—t.
The fact that they all get the same result is where we get the notion of time dilation from. How can light appear to be traveling the same speed relative to you, regardless of your speed? The answer is that the flow of time changes, too.
OK, let’s make the math simpler and say light travels at 200,000 km/s.
You “chase” the light at 150,000 km/s. So light should now appear to be traveling away from you at only 50,000 km/s, right?
If I’m observing, standing still, you will indeed seem to be losing only 50,000 km/s relative to the speed of light. But to you, time will go by at 1/4 the speed, so in one of YOUR seconds, light will travel four times further, and to YOU, it will still be going at 200,000 km per YOUR second.
Exactly. So the only yardstick in the universe that doesn’t change as you use it is light, it’s speed. I am sure that means profound things but I am just not capable of understanding what they are. The harder I try it seems I will never make that next step. I can almost feel it but I just can’t get there. It’s like the greek guy that was punished by frustration.
I don't think that at all. Though no genius, I'm smart enough to realize that there is a lot I do not, and prolly will never, understand....and at my age, I can live with that.
