Maybe a few minutes

>>12713890
Photons in 20 minutes!

>>12713890
Light always travels instantly

>>12713890
Estimates of the photon travel time range between 10,000 and 170,000 years

friendly reminder that virtual particles have nothing to do with physics

>>12713986
bullshit, they're literally everywhere, 99% of your weight is VPs

virtual particles aren't real they are a calculating tool, they are not actual things that exist.

>>12714093
Can you validate that?

at the core of a star is it dense enough to block the path of photons and cause them to bounce around before escaping?

>>12714098
you can calculate particle interaction using different methods that don't use virtual particles at all and still give the correct answers. They are literally just a calculating tool. In a feynman diagram only the ingoing and outgoing particles actually exist, everything else is there only to help make the calculations easier.

hawking radiation always gets brought up as some sort of evidence of virtual particles but hawking radiation is caused by quatum fields being disturbed by the blackhole, causing excitiations at the horizon. If there is no blackhole there are no such distrubances and there are no matter/anti-matter pairs popping into and out of existence. This is from hawking himself and the virtual paricle description of hawking radiation is only a helpful visualization tool.

>>12714115
your line of reasoning can be generalized

>>12714093
wrong

>>12714192
no, like i said with hawking radiation these do not imply virtual particles exist for similar reason.

>>12714173
>no matter/anti-matter pairs popping into and out of existence

See how retarded this is? Use your words, dumbass.

>>12714204
>Use your words
no point in re-inventing the wheel

stop reading popsci retards. Go talk to an actual physicist about what virtual particles are, nobody actually thinks virtual particles are real hence why they are called "virtual" particles in the first place.

As an aside you should always take measurement in quantum physics with a grain of salt. Our way of measuring things that small is like a blind person grabbing a giant stick with a bomb on the end and violently swinging it around the streets and if it explodes you know a person was there.

>my ass told me so

>>12714218
no one thinks they are particles,
bur they very much exist

>>12714231
which real life observable phenomena do they describe, or are an interpretation of?

LOL you fucking retarded piece of shit. Neck yourself or leave if you don't have the brainpower for /sci/. You're like those schizos that say [math] \tt{"BLACK~HOLE~ARE~JEWISH~LIE~WATCH~THESE~VIDEOS:}~\mathrm{[wall~of~links]"} [/math]. That's you, that's how dumb you sound.

>>12714231
exist as mathematical artifacts sure

>>12714247
lol wow, stupid is as stupid does

>>12714243
no experiments were mentioned in this article

>lol wow, stupid is as stupid does
I'm not even that guy you originally replied to. I'm the fucking op, you simpering potted plant. Brain-damaged schizos like you are the cancer killing /sci/, you are so stupid that you have no ideas at all, rather, all you can do is LINK somewhere. For whatever reason your breed of brainlets is just too fucking stupid to CALCULATE or EXPLAIN FUCKING ANYTHING. YOU CAN'T DO IT! You are not competent to THINK, and this conversation proves it!! I could easily automate every single one of your posts, your brain is a neanderthal walnut, you scientifically illiterate chimpanzee.
