Light will almost always travel from one place to another along a path that takes the least amount of time. This does not imply that it will take the path involves the least distance all the time.
But they do !
Light waves ALWAYS travel at the "Speed of Light"....based on the medium that the waves are traveling through. It just so happens that they go the FASTEST in a VACUUM.
No. They never traveled at the speed of light, and have always appeared tired.
Light always travels at the speed of light. The only time that's 299,792,458 meters per second is when the light is in vacuum.
There is no way to travel at the speed of light.
no it does not
yes
Almost exactly 0.3937 inch .
Light waves do not need a medium to propagate. Sound waves cannot travel without a medium. Light waves always travel at the speed of light that is 3*108m/s.
But they do !
no
It's always straight - as far as the light is concerned. If space is curved then the light follows the curve.
by itself many scientists figured out that light travels by itself you can see light moving you cant touch it and cant hear it same with oxygen. oxygen is always around us we breath it and sometimes see it

They don't really travel at the same speed, but, on television, the distance they travel is so short, that the difference between the speed of sound and the speed of light is almost non-existant.
Ethereal
Almost always a little oil can shaped light that will glow red.
