Question

Which light travels faster? The light created by the sun or the light created by humans such as from a light bulb?

Answer 1

both radiations travel at the same speed. For example, in vacuum, such speed is:
\[\huge c \simeq 3 \cdot {10^{10}}{\text{cm/sec}}\]

Answer 2

which is relative.

if you start racing at the sun, the light still speeds towards you at the same speed. as do you toward the sun and its photons.

Answer 3

lovely question... the simple answer is none is faster than the other in an ideal case (i.e in a vacuum.) Light has a constant speed.

But let's include some reality since your question didn't talk about vacuum.

The intensity of light, color of propagation, mode through which light is propagated, these all play a part and so many other things u can imagine:

In these condtions, the outright winner will be the sun.
