16:35 <Iskierka> a day late but note that photons do cause gravitational effects; for all purposes of modelling their interaction, they have mass. But they cannot have rest mass to travel at c

16:36 <Iskierka> however, a photon at rest is impossible, so ... kinda irrelevant except for explaining why photons are allowed to travel at c

16:36 <Iskierka> it's the only place photon mass comes up

16:36 <Iskierka> *rest mass

16:37 <Greys> is there any work done on the theoretics of what a photon might do if it experienced time?

18:46 <Greys> btw, change of plans; I'm moving to the day shift so I won't be awake near midnight on the 31st so I'm going to shut down before midnight on the 30th
