Does it involve plowing through your bean field?

I don't know.  Movement and vibration already creates photons.  Electromagnetic fields are nothing but photons and they're made by moving particles.  Thermal radiation is just atoms vibrating and creating photons as a result.

Don't let that stop you

New theory for detecting light in the darkness of a vacuum

Mr. Headline Writer, that's not a thing. In space, no one can hear you scream. But they can plainly see you're nuts.

/while we're at it, a vacuum isn't cold either

Motion makes photons or is the oscillating diamond detecting photons that blink in and out of existence?

The article used "detect photons" and "produce photons" in a way that confuses me.

Wine Sipping Elitist: Motion makes photons or is the oscillating diamond detecting photons that blink in and out of existence?


Could go either way.  The thing at the very least will produce radio waves just by waving atoms around.  Though, looking at their paper, they're vibrating the strip in the GHz range, which would produce photons in the same microwave band that they're detecting.  Or, it's Unruh radiation, where relativistic accelerations basically give enough energy to make virtual photons real as far as the accelerated thing is concerned.
