How long does it take for a single photon to travel from the sun?
An easy question, anyone can google the answer, but heres a slightly curly version.
If it takes about 8 min+/- for a photon of light to traval from the sun to here going by our clock, how much flight time does the photon experience by it's own clock due to time dilation?
I was reading the latest issue of Sky and Telescope and the cover story is on Superparticles. One of the blurbs in the article said that some of these particles traveling at near the speed of light are coming from light years away., sometime hundreds of light years but that the actual flight time for the particle was 20 min due to time dilation. This got me thinking about the question above.
Any ideas?
