How could we divide light traveling a Planck length in a vacuum?

If we take an indivisible unit of time (a Planck time perhaps), could the possible retro-causality hinted at in the Quantum Eraser Experiment be a process where the retro-causality goes back along the same plank unit rather than back in time per se Metaphor - I don't travel to a different train...

I'll jump in and say no. But like you I'm interested in this phenomena. I have a theory about this but it's too unproven for here and would likely see me burned at the stake

This sounds like a variation of the "hidden variables" idea to me

Thank you

"Suppose I put a red slip of paper in an envelope and a green slip in another then mix them up, keep one, and send another to the other side of the universe. I open the envelope and see green. Immediately I know the other is red. No communication took place - we simply have a correlation...

There seems to be some talk of Entanglement "defeating" the speed of light. But in these discussions people talk about c in terms of time frames - it takes Light X to travel Y ... etc If the Quantum universe simply doesn't facilitate such measurements then does that go someway to explaining...

Of course our gravitational relationship with the Sun and our own Moon are understood, but to what extent can we measure even the faintest attraction with other bodies in the Solar System. How do Mars, Venus and Jupiter effect Earth? Do we have Barycenters with these bodies and others more remote?

That makes sense Thank you

Hi all I'm a software developer who has been provisionally accepted onto a doctorate programme. I've always been a lover of physics and astronomy in particular. In short I'm someone with no formal education in Physics, but would love to work my layman's interest into my PhD. I've considered...

If I pick up my Wife, who is in turn holding our Daughter, both me and my Wife feel the respective weights. Me of holding both, and my Wife of holding our Daughter. How is my Daughter's weight split between my Wife and I?

Yes, No need to be rude

Does anyone here ascribe any particular broader meaning to them? Is that they represent indivisible units a consensus of sorts? Do they have real meaning or are they a kind of trite observation?

Yes I know the moon exercises a tidal force on the Earth for example, but doesn't drag people upwards. I'm struggling to define tidal force. I'll check Wiki

Right, sorry to sound thick. Bear with me. To me the tidal forces on Earth aren't trivial. We're being pulled towards the centre of the Earth quite strongly. A 15 feet fall can kill someone. The escape velocity of Earth is about 25,000 miles an hour As a non-physicist I'm struggling to...
