| May 25, 2017 at 9:45 | comment | added | Fis | I can also ask, why the light passes exactly the given distance in specified amount of time. Why it is not less or more? Not infinite, jut bit less or bit more. There is "something" what is limiting this value. In another words, there is something that makes the light (and its not just light, it is any kind of electromagnetic radiation and also gravity waves) "travel" exactly the measured distance at specified amount of time. And I am asking, what is limiting it or... setting up exactly this value? Dark matter? Dark energy? Gravity? Anything else? | |
| May 25, 2017 at 9:30 | comment | added | Fis | I got this. But the scale is still the same, correct?. I can also ask, why the light passes exactly the given distance in specified amount of time. Why it is not less or more? | |

| May 25, 2017 at 1:48 | comment | added | Fis | No, I would ask what is the reason the speed can't be bit faster or slower. But I am interested in reason. No the exact value. | |
| May 25, 2017 at 1:47 | comment | added | Alfred Centauri | I suspect that if it were twice that, or half that, you'd ask why it isn't twice that or half that. | |
| May 25, 2017 at 1:47 | comment | added | Fis | It seems I have found an answer here: physics.stackexchange.com/questions/3644/… Simply, we don't know why it's like that. | |
