| Oct 20, 2021 at 17:17 | comment | added | jamesqf | @user25375: Exactly! Like the prediction that mass and energy are equivalent, and related by the speed of light. Which seems amazingly non-intuitive: not only is the speed of light constant, it has to be in order to keep conservation of mass-energy. | |
| Oct 19, 2021 at 11:13 | comment | added | JohnEye | Judging by your question, you might find it interesting that while the speed does not change, the wavelenght does shift. So we can calculate our motion relative to the "rest of the universe" by measuring the doppler shift of the cosmic microwave background in various directions. | |

| Oct 17, 2021 at 4:46 | comment | added | jamesqf | As with many "why" questions, the answer is "because that's the way the universe works". If there's some fundamental reason for it, or for many other things (like quantum :-)), we certainly haven't discovered it. We just determine by observation that it works the way it does. then construct theories that explain the observations, and perhaps make new predictions. | |

| Oct 16, 2021 at 8:59 | comment | added | anna v | It is because you are thinking in Galilean transformations, and light follows Lorentz tranformations | |

| Oct 16, 2021 at 8:30 | comment | added | anna v | see this hyperphysics.phy-astr.gsu.edu/hbase/Relativ/ltrans.html#c5 and the measurement of this speed hyperphysics.phy-astr.gsu.edu/hbase/Relativ/lighthist.html . The Lorentz transformations have been validated by a large number of experiments in accelerators. | |
