DaveC426913 said:Yeah, Zz, I think we can assume he means "photons don't experience time".

ZapperZ said:This is where we have to define what is meant by "travel in time".
DaveC426913 said:One way, the question is so trivial as to be nonsensical, causing you to question if that's really what he meant, leading us to: the other way - an extremely common concept that trips up and confuses almost every new student to SR. You don't think, even it retrospect, that it should have been obvious which?

The concept of time travel for photons is a complex one. According to the theory of relativity, time is relative and can be affected by factors such as gravity. Photons, being massless particles, do not experience time in the same way that we do. This means that from the perspective of a photon, it does not experience time at all. However, photons do travel through space at the speed of light, which means that they are constantly moving forward in time in a sense.
No, photons cannot travel backwards in time. The theory of relativity states that the speed of light is the maximum speed at which anything can travel in the universe. This means that photons cannot exceed the speed of light and therefore cannot go back in time.
Time dilation is the phenomenon where time moves slower for an object that is moving at high speeds. Since photons travel at the speed of light, they are not affected by time dilation. This means that from the perspective of a photon, no time has passed even if it has traveled a great distance.
At this time, there is no known way to use photons for time travel. While photons do not experience time in the same way as we do, they still follow the laws of physics and are subject to the speed limit of the universe. In order for time travel to occur, an object would need to exceed the speed of light, which is not currently possible.
The twin paradox is a thought experiment that explores the effects of time dilation on two twins, where one stays on Earth while the other travels at high speeds. The twin who travels would experience less time due to the effects of time dilation. Similarly, a photon traveling through space would experience no time at all, while the observer on Earth would experience time passing. This concept is related to the twin paradox, but it is important to note that photons do not have a conscious experience of time like humans do.
