The light is redshifted when it "climbs out" of a strong gravity field but still moves through space at a constant speed. https://en.m.wikipedia.org/wiki/Gravit

- benj111 7y agoOk that makes sense. 2nd stupid question: I though gravity acting on light was a 'light as particle' thing, rather than 'light as wave' thing? If that were the case gravity acting on light as particle manifesting in light as wave doesn't seem consistent.
- simonh 7y agoI think most of the time it's best to think in terms of waves, but every now and then they exhibit particle-like behaviour. Any such attempt at simplification hits problems though. I think the best approach is to be pragmatic and simply follow the observations and what the experiments tell us rather then force it into one paradigm or the other and complain when it doesn't make sense. This is sometimes referred to as the "Shut up and do the math" approach.
- SiempreViernes 7y agoA photon being a particle or wave is mainly about pedagogical convenience, it is neither but has properties of both.
- saalweachter 7y agoDepending on your metaphilosophical models, you might also say that both waves and particles have light-like properties.
- Iv 7y agoA photon does not switch from particle behavior to wave behavior. Physicists do. These are two different models for the same thing. In some ballistics problems, you'll consider a flat earth (baseball problems) in some others a spherical one (spaceflight). It is about which model makes the math simpler.
- SiempreViernes 7y agoI'd say physicists are pretty constant in their coffee seeking behaviour (the dominant operation mode).
