# Duality of Light

Is there a possibility that light can be a particle and wave at the same time? If so then there is the proof that there exists a physical manifestation of 4D space.

I'm almost afraid to ask but, what makes you think one leads to the other?

Well, if there was 4D space that means that there is a chance that two events can happen at the exact same time. Thus, what if light as a wave and particle are two events happening at the same time? (wave properties being the first event and particle properties being the second event)

Your logic escapes me. Even if there WERE a 4th spacial dimenision (which I dispute) it does NOT follow that two events could happen at the same time AND why would "two events could happen at the same time" follow from the duality of light?

Light IS a particle and a wave at the same time in 3D; why do you need a 4th?

Light acting as a wave is an event and light acting as a particle is another event. Recently, I've watched a video that described shapes in 4D space and the hypercube's "shadow" is a cube and that is what we perceive in the real world.

Light as a wave and light as a particle are "shadows" of "Light" which exists in 4D space.

Quantum mechanics does perfectly well without introducing a 4th spatial dimension, as far as I know...

No, they are not.

Light as a wave and light as a particle are "shadows" of "Light" which exists in 4D space.
This sounds suspiciously like an assertion based upon a personal or otherwise unpublished theory. PF expressly forbids personal theories, as you will have read in the rules when you signed up. If you pursue this assertion further this thread will be locked.

You may ask questions as to why it is not so, but you may not make unfounded assertions. Consider yourself given fair warning.

Dave, you said that SO much more elegantly than I did. But I was briefer
