The speed of light is not always fixed at 299792458 m/s. In earth's atmosphere, the speed of light slows, though this is negligible. In water, light travels at 75% of c, and in a diamond, light travels at .40 c. C is the speed of light, rounded to 300,000 km/s.
True, the speed of light is faster in a transparent medium like water or glass compared to its speed in a vacuum. This difference in speed is due to the different refractive indexes of the medium, which affects the speed at which light travels through it.
No, the Flash is a fictional character from DC Comics with superhuman speed that exceeds the speed of light. In reality, nothing can travel at or faster than the speed of light according to the laws of physics.
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air

No, according to the theory of relativity in physics, information cannot travel faster than the speed of light in a vacuum. This is because as an object with mass accelerates towards the speed of light, its energy increases towards infinity, making it impossible to exceed the speed of light.

No
If you observe a clock moving past you at the speed of light, it will appear to you to have stopped.
Light is about 800,000 faster (compared to the speed of sound in air).
Light.
The speed of knowledge/information travels faster than the speed of light.
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
Light is faster because speed does not move. Speed is a measure of the rate of movement but, in itself, it does not move - at all!
It gets faster. As a result, it also changes its direction.
Nothing travels faster then the speed of light (according to our understanding of physics)
* The speed of light in a vacuum, * The speed of sound,
No, not quite. We know that for sure, because nothingmoves faster than the speed of light.
