It seems that the paper is making theoretical strides in the limitations of producing a positron beam via the Breit-Wheeler process. From Wikipedia

This mechanism is theoretically characterized by a very weak probability, so producing a significant number of pairs requires two extremely bright, collimated sources of photons having photon energy close to or above the electron and positron rest mass energy. Manufacturing such a source, for instance, a gamma-ray laser, is still a technological challenge.

I'm not claiming I know this stuff. I was just trying to figure out what was new here since I didn't find the headline very surprising.

Hard light would be a cool thing to see in this shitty timeline.

This is the best summary I could come up with:

Plasma could be wrangled to collide photons and yield matter, according to physicists who ran simulations to explore the practical applications of a world-famous equation.

“We feel that our proposal is experimentally feasible, and we look forward to real-world implementation,” said Alexey Arefiev, a physicist at UC San Diego and co-author of the paper, in a University of Osaka release.

In 2021, a different team of researchers suggested that the cores of neutron stars, extremely dense end-stages of stellar life, could be a venue for a similar dynamic, by which dark matter particles could convert into photons.

Spinning neutron stars are called pulsars, and their high-energy environment is where matter may be generated from light.

Pulsars can spin thousands of times per second, emit gamma-rays, and have some of the strongest-known magnetic fields, according to NASA.

The experiment could provide a way to peer into the universe’s composition, by bringing some far-out physics much closer to home.

The original article contains 458 words, the summary contains 157 words. Saved 66%. I'm a bot and I'm open source!

Is it practical beyond confirming Einstein's equation works both ways, with all of the theoretical implications?

Considering you need a ton of energy to produce even a milligram of matter (8,99*10^10 J, or 24,7 MWh, assuming 100% conversion).

Light bridges and Light sabers, let's go!

When, far in the future, the next functioning society eventually makes an Experiential Media (or whatever they will call movies) about the collapse of this society, this headline will definitely be in the opening montage.

Isn't it what particle accelerator are doing already? From my understanding the CERN is colliding particles and some of the energy from tge collision is turned new particles.
