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.
Update:
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.
The sailfish is the fastest swimming ´thing´on earth. It can reach speeds of 120 kph.
The fastest thing on earth is Light. Light travels at a speed on 186,000 miles per second, or 299,000,000 meters per second, so light is the fastest thing on earth
Imagination
The fastest thing known on Earth is LIGHT.It travels at the speed of 186,000 miles per. second.
The second fastest land animal on earth is the Pronghorn.
Light
A meteorite .? :p
tasha :) lollz
light
The pedigree falcon
yes
The peregrine falcon is the fastest animal on earth. It can fly at almost 400 km/hr. The cheetah is the fastest land animal.
