Scientists discover something faster than light

The Dark Side of Light Moves Fast

Zero-amplitude vortices in polaritons defy local speed limits through exotic wave physics.

Think of these “dark points” like whirlpools in a river that can spin faster than the water flows around them. Researchers used polaritons-hybrid light-matter particles-in a thin flake of hexagonal boron nitride where light crawls 100 times slower than normal. Within this sluggish environment, the team watched dark vortices accelerate to unbounded superluminal speeds during creation and destruction events.

Of course, so, "Dark" has no mass or wave amplitude...

 

It's like Obiwan Kenobi said: "There's always a bigger fish".
No matter how fast "Fast" is there's always faster. We just haven't found it yet.

 

It is basically saying they have proof that nothing got there first before something did... i.e. nature abhors a vacuum. I did find the idea of vortices of "nothing (having no mass or amplitude)" moving faster than particles or waves of light an intriguing concept.

It's literally "much ado about nothing."

Vortices of "nothing" was the physical (physically incorrect Luminiferous Aether but the math was correct) model of the original Maxwell Equations.

Light speed has never been the standard for speed limits, it's causality that limits the speed of interactions.

 

What is the data rate of a dark vortice?

 

Phase velocity vs group velocity. Look it up. Nothing new here.

 

Even objects can be made to appear moving from each other faster than light.
If you send one object off at 75% the speed of light, and a different object in the opposite direction at 75% the speed of light, they would appear, from our perspective, moving away from each other at 1.5 times light speed.
But from each objects time-frame-of-reference they would still be moving apart from each other at less than the speed of light.

Please consider that all velocity measurements are RELATIVE to some reference. Convenient to us, the normal reference is usually defined as being stationary. BUT, as C points out in post #9, it is possible to select a moving reference. Thatis a great method of stating "a falshood by omission."

Certainly I would demand that the ones making any such claim explain the derivation of their data. And watch them stumble!!

How did I not consider that?
I stated the objects were moving from "our perspective" which is the implied reference (stationary) point.

 

 

Velocity relative to a second moving object is not a part of this discussion, as I see it. Other opinions may differ. That is fine with me.

Everyone's got a little crazy in them.

Sounds like a commercial for Apple products back in the Steve Jobs era ...

 

And yet, there are a few respectable scientists out there that believe that FTL travel or communication is actually possible:

It is allowed for folks to be in error and still be allowed to speak! AND it is reasonable to expect folks to be able to explain why they think someting is possible. I usually allow those folks who I think are in error to explain their reasoning. Some times, as they explain, the error becomes obvious to them. AND that is much better than arguing.

 

If you are in a spaceship that is traveling at the speed of light, and you turn on the headlights, does anything happen?
-- Steven Wright

I am faster than the speed of dark.
I can turn off the light and be in bed before the room gets dark.

Normally I just reach over and switch off the light.
But for the two steps down light, I just switch the switch and get down the steps before the LED fades out. Not fastat all. UNDERSTAND that the light does not stop when the switch opens. NOT EVEN for a 100 watt incandescent light bulb.

 

I've always wondered what happens when a fridge moves at the speed of light. Does the light turn on before the door opens?
