This is pretty interesting. Some things I didn't know in there, some things I did know.

Worth a glance.

Electricity does NOT travel at the speed of light

Many textbooks claim that Electricity (electrons) within wires flows at nearly (or even exactly at) the speed of light. In fact it's the electrical energy which flows rapidly ("rapidly" is still slower than the speed of light). Electrons, which have mass, can never travel at the speed of light due to the theory of relativity. The drift velocity of the charges in an electric current is extremely slow, on the order of centimetres per hour. Where the electric current is visible, as in electrophoresis, the slow movement of charge carriers can be seen directly.

As a very rough analogy, imagine a line of people at an amusement park. When the people at the front board the ride, a space opens up, and rapidly spreads to the back of the line. However, the average velocity of any one person is far slower than the speed at which the space moves.

She's next to me surfing on her computer.

haha.


Evy give your man some attention!

ya we move at the same speed as the earth. but the earth doesn't accelerate. The speed is constant. We only feel acceleration. so we don't feel that we are always moving at like 30.

There is NO "dark side" of the Moon

The Moon is in synchronous orbit --this means, it takes exactly the same time to rotate once around its axis than it does to make one orbit around the Earth-- so it has a far side, because it always keeps the same hemisphere pointed towards Earth. When the Moon is roughly between the Sun and Earth, it is daytime for the "far side" and night time for the "near side". When the Moon gets "behind" the Earth, it is night time for the "far side" and daytime for the "near side".

Ill see you on the dark side of the moon......

yep, and gravity keeps us from flying off the earth. but unlike you, i dont feel compelled to type out random bits of common knowledge to try to impress people. only to try to insult people.

so define "gravity smart guy" without search engines.

was the initial post not common knowldge???? the whole schpeel about moving on earth vs earth moving????????

oh and if the rotation of the earth isn't common knowldge then neither is the idea of the earths constant speeed.

classical or general relativity?

edit: upon closer inspection, i realize i misread the quesiton. i have no idea what a "gravity smart guy" is.

True Relativity.
