1. ### Perception of motion in a void

Agreed, agreed, agreed. This is so wrong, please ignore. Reason: it assumes more parties than (A) absolute space (B) ball (C) person. ALTHOUGH, it can be said that either [or a combination of] (B) and/or (C) are moving. It is, in principle, calculable, if you replace either (B) or (C)...
2. ### Perception of motion in a void

I was vauge, I mishmashed different points. Yeah that's exactly what I meant :) I was also saying that if you and the ball existed in empty spacetime, and ONE of you were changing directions, you would know, as you would be able to detect inertia. (That ISN'T the example in the OP, but I...
3. ### Perception of motion in a void

If it appeared you or the ball was going left to right to left, you would know, as there is the Higgs Field and thus you would feel inertia. But if you were sleeping, and you woke up with you or the ball spinning one way with no changes in direction (no acceleration), you wouldn't know. But...
4. ### Why does PI occur so much in physics?

What's so special about PI? Why does it appear in so much in physics? Einstein's field equations, Coulomb's Law, Kepler's Third law constant, uncertainty principle.... This wouldn't be a co-incidence. Surely there's an underlying reason for this that we don't know yet?
5. ### Why does ElectroMagnetic radiation propagate forever?

WHAT I SAID: "Since the speed of light is propagating at c, isn't it stationary in the 4th dimension?" WHAT YOU REPLIED: "Once again, I'm not sure where you've read this, but it is not possible to associate a [locally] inertial reference frame with a photon. Therefore, it is non-nonsensical...
6. ### Why does ElectroMagnetic radiation propagate forever?

You misread what I said. I know 'massive particles' cannot travel the speed of light because as they do they gain mass and would fill up the entire universe in order to travel at that speed. plus an unrealistic amount of energy would be required to travel at that speed. What you quoted was...
7. ### Why does ElectroMagnetic radiation propagate forever?

Hey there, I am not a physics student, nor have I ever studied physics. I have this question though (read thread title). I have googled for an answer but couldn't find any. According to Einstein, we are always traveling through the universe at the speed of light. When we are still, A...
