>>hey went the other way and converted “massless” (having no rest mass) particles, photons, into “massive” (having rest mass) particles, W- bosons.<<
I am no physicist but I understand enough to know that they may have to completely recast how energy works.
This is not “something out of nothing” but as close as we can get.
Too bad only our great- great- great grandchildren will get free energy from it.
Unless the democrats call it “quantum change” and protest against it.
I always wonder what gives these tiny blobs energy in the first place...why do atoms, all subatomic particles, and energies keep on keeping on?
