Were it not for this little problem, I’d be able to crank out an issue of US “X” P every few days, or an APR in a week…
Structured photons slow down in a vacuum
The claim has been made that scientists have figured out how to make photons in a vacuum travel a tiny little bit slower than the accepted speed of light in a vacuum…
The researchers created a source that emitted pairs of photons simultaneously. One of the photons went straight to a highly precise photon counter, while the other went via two liquid-crystal masks, which imparted their profile onto the passing particle of light.
Across a propagation distance of 1 m, the team found that the spatially structured photon lagged behind its partner by between 10 and 20 wavelengths. That equated to a drop in speed of about 0.001%…
As described, this sounds insufficient to me. I can see a number of reasons why they’d see a slight lag across a 1 meter gap, not least being that the photons simply rattled around a little bit in the apparatus before going on their way. The real test would be to test the lag time over *numerous* distances… 1 meter, 2 meters, five, ten. If the lag time is the same, then the speed of light is unchanged, there was just a slight delay at the beginning; if the lag time expands as the distance expands… then, yup, you’ve got yourself light that travels slower than light.
And that would be kinda… disturbing.
Huh.
It turns out that dunes can form on comets. Seems unlikely for a worldlet with such low gravity, but there it is.
