Well today I was reading much about the subject of light and photons.And we agree that photons are massless and taht is the reason they travel at c. But if something travels at c then it means it has no time as is said and if that thing traveling at c has no time then it means for a observer that has time like we do a photon should be everywhere at the same time , so how come we measure cosmic distances with light years if it takes no time for a photon do do that distance and in fact it is as well as at the start of this distance and in the same time in every place and point in this distance?
Or is it that even traveling at c means you have a very huge but still measurable speed ? But if so then how come we say that a photon is everywhere at the same time?
Ok my head is a little bit overloaded today so I apologize if this question has been around for ages.
