Are superluminal speeds possible?

[crawler]

Light propagates at c kmps in the aether. An object can travel at almost c kmps in the aether. And two objects travelling at almost c in opposite directions can have a relative speed of almost 2c kmps.

A different form of this question is -- can an object catch up to light?
, not if they are travelling on the same line.

The rule of adding speeds:
https://en.wikipedia.org/wiki/Velocity- ... relativity


If we have 2 objects starting from one point, traveling in opposite sense, the rule is to use the formula above, so that the speed between them cannot exceed c.

Problem: speed is distance/time. It can't be anything else. If each object reaches a certain destination, and we calculate it's individual speed with the distance/time formula, let's say we obtain 0.9c for each object. Meaning 1.8 c between them. Those objects reached certain destinations in a certain amount of time. If the speed between them is any less (because we use the velocity addition formula) - it means they did not reach those destinations, and this is a contradiction.

I mean - each object can reach individually its' destination, obeying the rules of relativity at 0.9 c. Then if we add the velocities using the special formula they are suddenly traveling slower. Meaning they did not in fact reach their destinations...

But they did reach their destinations, because that was the hypothesis, and there was nothing wrong with the hypothesis - regarding breaking any laws of physics. Well, it's just a "paradox". Maybe some "dark speed" is involved or something, who knows.

Yes, of course.
