>>8421391
Wave–particle duality is the concept that every elementary particle or quantic entity may be partly described in terms not only of particles, but also of waves. It expresses the inability of the classical concepts "particle" or "wave" to fully describe the behavior of quantum-scale objects.

nice fucking meme.

I forgot how retarded /sci/ was that's why you're all CS college students who haven't dropped out yet, in reality.

There is no proof that gravity is transmitted as a fucking wave and it's one of the most retarded theories I've ever heard. It's not in the (complete) standard model of PP which includes all wave-particles in the universe.

Gravity is a fundamental force yes
Do the other 3 have carrier wave-particles?
yes

Why doesn't gravity?
Because it is only a fucking bend in space-time according to Einstein, it's not a fucking will do to motion like the other 3 FFs.

This is also the reason gravity fucking affects light which is stored in FUCKING BOSONS.

Explain that dipshit.

You guys are idiots please get >>>/out/ of /sci/.

Particles and waves have been proven for years to be related as one.

A particle is a "frozen-state" of a wave and vice versa. So they can be considered the same thing but only in certain aspects and such.

Where the fuck is your agrument aside from quoting something I said that's not even inccorect? Other fucking particle physics not just myself have used this description too many times if you actually read about the subject you'd see it too.

Everything so far is a wave-particle and there is nothing that is purely either-or.

When a wave gains enough energy it becomes a particle and viseversa. it "freezes" that's the fucking technical term to use you samefagging pepe-posting meme-loving highschool dropout.

I still don't understand how we could/can detect gravity waves. when the warpage of spacetime changes due to a wave, how would you detect it, since all signals would have to travel through that fold?
Do you measure in several directions and locations simultaneously and hope the waves are polarized?

To me it still seems like bending a sheet of paper that an ants walking across, how would he know the papers no longer flat to an outside observer? He still travels same path, time, distance etc. So likewise wouldn't signals for measurement do the same?
Even if you think of the gravity wave as a moving fold or gravity well, while light is traveling across that longer path across warped spacetime, it still appears to be the same speed and cover the same distance to an outside observer.

I can understand measuring relative dilatation, or frame dragging, since it can be later measured comparing local measurements to distant observers measurements. But if the gravity wave were to go parallel in plane of our solar system, wouldnt any instruments measuring in that plane all measure the same distortion one after another so all later measurements end up matching later? Unless the wave travels slower than light, I don't get how the information would be sent to show the distortion.

Or does this all rely on hope that the wave has an axis and isn't traveling outwards as a sphere, and then taking measurements across several perpendicular directions hoping for one that's propogating in a different plane than ones the device is observing?

Metric tensor on your pseudo-manifold changes. You can measure that distances change in a certain pattern.

>To me it still seems like bending a sheet of paper
Bending a sheet of paper is specifically defined as isometric transformation = preserves metrics. That's why it preserves any intrinsic properties.

>>	Anonymous Wed Oct 19 07:46:01 2016 No.8422226 >>8422225 But how to you know space bends?

>>	Anonymous Wed Oct 19 07:54:00 2016 No.8422234 >>8422226 Distances change in a certain pattern. You can measure how long does it take a light to go a certain distance (LIGO measures this using lasers), and it changes when the wave passes.
