Three Ways to Travel at (Nearly) the Speed of Light NASA

WebLight travels at a constant, finite speed of 186,000 mi/sec. A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second. By … WebLight travels at a speed of 299,792,458 m/s (that’s nearly 300,000 km/s!). The distance around the Earth is 40,000 km, so in 1 second, light could travel seven and a half times around the world. Sound only travels at about 330 m/s through the air, so light is nearly a million times faster than sound.

When talking about "the speed of light" it is referring the speed of light in a vacuum. Certain variables such a medium (air, nitrogen, space, etc) and photon energy have an effect on speed. Also there is the trailing effect of photons that gets even more odd. 2.

In other words, … WebIn the experiments you mentioned, the extremely sensitive detectors can distinguish photons arriving with a time difference just a few nanoseconds or less, due to the slightly different paths they take (space becomes very important in less obvious ways) Light can even “feel” the geometry of space-time, as is demonstrated by the deflection of …

WebThat is, we find transformations between frames of reference by postulating the speed of light being constant. On the other hand, once we have constructed the theory, the fact that secures that we see light in vacuum to move constant in every frame of reference is the Lorentz transform.
