Physicists Broke The Speed of Light With Pulses Inside Hot Plasma
Never thought I'd see this happen.

https://www.sciencealert.com/p...es-inside-hot-plasma

But impressively, last year, researchers from Lawrence Livermore National Laboratory in California and the University of Rochester in New York managed it inside hot swarms of charged particles, fine-tuning the speed of light waves within plasma to anywhere from around one-tenth of light's usual vacuum speed to more than 30 percent faster.

Nothing good will come from violating causality.

That article was a bit above my science level but interesting they can achieve this.

When I lived in Livermore I knew a handful of guys that worked at the lab. Not sure if still true but that town has biggest per capita of Phd residents due to the lab.

So they got light to travel faster than light? That just ain't natural I tell ya!

So the big question, what does this all mean?

For the moment, not much. It doesn't mean that we'll soon be traveling through space at warp speed- yet.

Let me see if I can help.

This quote from the article is the key.

quote:
… under certain conditions, waves made up of groups of photons can move faster than light.


So photons, which have no mass, can join together into waves of nothing which yanking each others’ photonic cranks pulls the waves, (not the photons!) of nothing faster than the speed of of photonic light, as expressed under certain conditions. See, it’s really simple.

You still haven’t. This is a case of a poor translation of a complicated scientific concept into layman’s terms.

What they did didn’t make any photons move faster than C and can’t be used to transmit information faster than C.

They made the interference peak between two waves move faster than C.

What they did is more like if you (standing on the earth) swept a very powerful laser pointer very quickly across the moon. You could make the position of the dot swipe across the moon faster than C, but no actual thing is moving faster than C and information isn’t being transmitted faster than C.

For decades, they have discovered something does travel faster than the speed of light. it's based on splitting a particle and the two halves are somehow connected in that when you flip one, the other one flips to correspond instantaneously no matter the distance the two have traveled away from each other.

The progress is such that they are working on making this principle the basis for a network.



"It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life – daily and hourly. Our answer must consist not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual."

Quantum entanglement. Personally, I doubt that it’ll ever prove to be a practical means of faster-than-light communication.

What they're "working on" is justifying their jobs and paycheck, and counting on people not comprehending this gobbledygook. Oh, just look at how brilliant they are. This generation will be the one to figure out all the mysteries of the Universe. Roll Eyes

This is nothing new. Three card monte has been around for a very long time.

As an example- Dark Matter. Astrophysicists attempted to determine the total mass of the Universe and attempted to explain the expansion of the Universe, and when their numbers didn't add up, what did they do? Did they state the truth, which is that we simply do not have the answer? No, they plugged in a factor to their equation and called it "Dark Matter". We can't see it, but it must be there, because a group of scientists on a little blue rock in the vast emptiness added up some numbers. Fucking ridiculous, and they actually get away with this con game.

If these government-funded charlatans had any real clue, they would acknowledge just how very ignorant we are, and they would acknowledge that theories of the past get proven wrong all the time, and that includes the double-talking bullshit these con artists are putting out.

"What have you done recently to justify your paycheck?"

WE WENT FASTER THAN THE SPEED OF LIGHT!!!!! Roll Eyes

Thought a tachyonic particle did this already?

You mean a 1.2 billion dollar tachyonic particle.

Yup. Dark matter and dark energy just show how much is lacking in their knowledge and calculations.

Another example is the Hubble Deep Field. Until those exposures were made astrophysicists considered that spot just a patch of dark sky. But hey, whadda ya know? Roll Eyes

Oooh, look, there's some of that "dark matter" we've been missing. It ain't so dark, but...

The JWST will further reveal our ignorance. Hell, I think it has done so already.

We need to stop thinking ourselves so very special. We need to stop believing that we are fundamentally smarter than previous generations of humans. We need scientsts who are honest with us and with themselves. We need humility.
