The peregrine falcon is the fastest animal on earth. It can fly at almost 400 km/hr. The cheetah is the fastest land animal.
Any electromagnetic radiation, such as radio, heat, light, X-rays, etc.
The fastest thing is LIGHT, but ELICTRICITY comes a close 2nd. The fastest animal is the swift, speeds range between, 180mph to 200 mph. Light travels at different speeds depending on the density of what it is traveling through. In space, it travels 186,282.397 miles per second!
The sailfish is the fastest swimming ´thing´on earth. It can reach speeds of 120 kph.
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.
Imagination
Lasers or any other beam that travels at the speed of light.
A meteorite .? :p
light
light, it travels at a unbelievable speed.
Biology is the study of every living thing on earth.
The fastest living thing is the cheetah. It can run up to 80 miles per hour. Sometimes even more than that.
It Dies (ceases to be a living thing).
