Answer 1:

Light is the fastest thing on earth. Light travels about 186,282 miles (more than seven times the circumference of Earth) in one second. In modern physics, light is regarded as the fastest thing in the universe, and its velocity in empty space as a fundamental constant of nature denoted by c.

Actually from what I learned in science class light TRIES to travel at c and can, when it hits an object, go through it, reflect off of it, absorb and turn into thermal energy (heat) or reflect. It also is the fastest thing in the universe. It travels in waves that move in straight lines. The only thing you can see is light.


Despite fairly recent experimental results that suggested neutrinos could exceed the speed of light in a vacuum, this has since been attributed to measurement error.

See the "related links" for a recent story on this matter.
