Scientists Prove That Light Can Stop Electrons

Hello ATS. I found this interesting article that I think you'll all be interested in as it lays the claim that scientists at the Gemini laser at the Science and Technology Facilities Council’s Central Laser Facility in England have achieved the feat of stopping Electrons with light. Apparently, intense light on fast moving Electrons causes those electrons to stop moving. Energy overload anyone?

Normally, when electrons are ‘hit’ by photons, packets of light, the electron gets a little boost of energy. But now imagine the electron is moving very fast and the light is very intense. In this scenario, something completely different happens. The electrons vibrate violently in the presence of the really intense light beam, so much so, that they radiate lots of energy and slow down. This process is known as a ‘radiation reaction’.

The team did this by colliding a very high-power laser with a high-energy electron beam. The laser was one quadrillion times brighter than the light emitted from the surface of our Sun. The experiment was carried out with the Gemini laser at the Science and Technology Facilities Council’s Central Laser Facility in England. When the high-power laser beam successfully hit the high-energy electron beam, the laser light gained energy from the collision and shifted in color (frequency), resulting in gamma rays.

This is an exciting discovery, ATS! Although, I'm not 100% sure what the implications of this discovery are. Maybe some applications for invisibility? I'm not sure if this discovery has anything to do with mass or not either. What would happen to everyday objects and people if the light the emanate could be stopped? What about aging? I don't know.......What says ATS?

I'm going to go with light sabres.

But with gamma radiation, we're now talking "The Hulk".

So I'd say zombie apocalypse is the most likely end-scenario.


Other than that, it brings more to the discussion on light as having properties of matter.

That is very interesting.

I would love to know the configuration of the experiment and the shape and nature of the machinery it used. I also find the fact that interactions between electron beams and high powered lasers could produce gamma rays... this is FASCINATING!

Yes, I noticed this too.

gets weird when they wonder if the future effects the present.

light is light.. dont get confused when they call it "gamma ray, photon, electomagnetism"

most light is invisible, but its all "on the spectrum" bad joke lol sorry.

photon adds energy to electron electron releases energy as photon. electromagnetic radiation. electricity, magnetism are photons or "photon exchanges."

light is a lot more key to reality than most realize i imagine. thought experiment: whats a photon made of? Some "unified field?" that would be fun.

im always trying to wrap my head around the subtlty.

ha maybe one day

I hadn't thought of that!!

This is a huge discovery if unknown until now (at least in the "white" science world)! This basically means we can now extract energy from electrons, I didn´t read it all yet because I wanted to deliver the direct link to a more detailed article:

You should get an idea from it.

Fascinating!!

This:



Is a comparision with the current "mainstream" physic models.

Notice how the data hints towards a huge misunderstanding currently and that if you consider there could be a third model that was not plotted, it would be 50/25/25 against the classical and quantum theory!!!!!

Either models need to adjust or we are way offtrack, at least that´s what the data suggests. We need more shots and variable lasers to get more data to analyze.

Sorry for my bad english, I´m verry excited!!!

Yes but that´s a completely different thing physically.

What it proves is photons exert a 'pressure', calling that what you will.

ETA: thru absorption and repulsion.

The experiment made use of the Gemini laser at the Science and Technology Facilities Council's Central Laser Facility in the UK; a device capable of delivering an ultra-intense beam of light in a matter of femtoseconds.

On the other side of this awesome collision was a beam of electrons pushed to high speed using laser-pulses in what's known as laser wakefield acceleration.

When a ridiculously intense beam of photons meets electrons kicked up to speeds approaching that of light, this whole radiation reaction becomes a serious force.

Or as physicist Alec Thomas from Lancaster University and the University of Michigan put it, "One thing I always find so fascinating about this is that the electrons are stopped as effectively by this sheet of light – a fraction of a hair's breadth thick – as by something like a millimetre of lead."

sciencealert.com - For The First Time, Physicists Have Slowed High-Speed Electrons Using a 'Sheet of Light.

A femtosecond is one quadrillionth of a second! They were using sapphire to make petawatt bursts. The new lasers, take that burst and can drive higher energies and/or shorter pulses. The femtosecond bursts creates a "sheet" or "curtain" of light (same source), which they shoot the electrons at. The "radiation reaction" shakes the electrons to give off gamma ray bursts. In return the electron, now with less energy, slows down its vibration energy.

What does it mean? Well, the first thing I can think of, is the wild whipping of matter and light around the accretion disk of a black hole can now be modeled in the laboratory instead getting close to a black hole! At those speeds and energies you need to take quantum effects and interaction into account of your calculations. If a small portion can be tested, then computer model tested at bigger simulations, then you find out about some of the most mysterious objects in the universe!

I wonder what happens to the electrons?? Nobody has said!

Anyway, we all know that a squadrillionth of second is just frikken' cool!

Light is going to be weirder than anyone imagined.

This may be in the same vein as my aging question but I also wonder if by stopping electrons, one could stop time...?

a reply to: lostbook

I'm assuming that the high intensity laser beam was below the photoelectric threshold, as not to re-energized the very electrons they're trying to de-energize. Am I correct?

So, if there exists a “stopped” electron, that implies that it has zero momentum. By the uncertainty principle, that means its position is completely delocalized. In other words, the electron is literally everywhere in the entire universe at once. For all intents and purposes, the electron has been lost forever.

If every electron in a single atom were lost, that probably wouldn't be a big deal. The atom would violently strip away electrons from its neighbors, but it's just one atom. If all the electrons in your body were suddenly lost, you would probably explode. And I don't mean a run-of-the-mill explosion either. I'm not going to calculate the actual energy output, but I would hazard a guess that it would be a world-ending explosion at the minimum.

Quora - What would happen if every electron stopped moving for a second?

Well, I guess that exploding is one way to stop aging!!

Somebody else stated that it would imply absolute zero. Your atoms would become one entangled quantum jello acting like a Bose-Einstein condensate. Again, you would not be "getting older" in the regular use of the term!

a reply to: lostbook

how do they now if its a quad time brighter if they never been there? we know now our senses decieve us, is it possible to create somethin that much brighter than sumthin we havent been able to sample? i think they lookin in the wrong place to control the "energy". what if they could slow down say a third party & conjoin em. lol idk chemicals just spitballin but it could get closer to a controlled cycle i guess lol

Each photon consists of an electric field and magnetic field perpendicular to each other. That provides the basis for each photon having a polarization plane.

Electrons will absorb and emit photons. When bound to an atom, each electron is bound to a particular energy level and will only change levels by absorbing or emitting photons of particular frequencies. Being in free space, interactions with photons would make the electrons bounce around like ping-pong balls as they exchanged energy with photons. But in this set up their motion would be constrained by a strong magnetic field in order to keep them in a very tight beam. So being trapped in a magnetic field would be like being trapped in an electron shell around an atom When they hit a stream of photons, they could only accelerate forwards or backwards by absorbing photons or slow down by releasing photons. That would require exchange of energy with photons which could only by achieved by the photon increasing frequency into gamma ray energies (1 million times the energy of a regular visible light photon)

The brightness of environments is measured using measurements like lux, lumen, candela and color temperature, which are measures of how many photons are being emitted and what energy.

If a Bright day is 10,000 lux, then a night-time sky is 0.0001 lux. Then everything can be measured relative to this range. Concentrate 10 cm^2 of sunlight into 0.1 cm^2 using a magnifying glass, then the energy received is 1,000,000 lux
Use a laser or bank of lasers, then that could easily be a quadrillion times brighter.

Layman's translation:

Scientists attempted raising the sample rate of electrons for some nefarious reason, and found a pre programmed speed limit.

That would be a great way to stop aging. lol
