Thanked: 22If everyone in China held hands and jumped up and down simultaneously, they would knock the planet off its axis.
So I have heard, but with a billion of them jumping up and down it wouldn't surprise me.

That's screwed up. Even if it didn't knock the planet off its axis, I bet someone would feel it somewhere.
Polaris, in the tail of the Little Bear constellation, is the closest visible star to true north and thus is referred to as the North Star. By about 2100 A.D., the wobble of Earth's axis will slowly begin pointing the North Pole away from Polaris.

Thanked: 131The NASA Space Shuttle's launch pad is moved into place by two transporters called Hans and Franz which weigh 2,700 tons each. These transporters move the shuttle at a zippy 1 mile per hour

Thanked: 0Continuing the cosmological facts:
Venus was a planet much like earth eons ago, its co2 emmisions gradualy increased until it hit the point of no return and things spiraled.
Now Venus has a runaway greenhouse effect that keeps the surface of the planet hotter than the Mercurian surface even though its twice the distance of Mercury from the sun.
Even in the dark side of Venus the surface is capable of heating lead to its boiling point.
On its surface there is 90 atmospheres of pressure, about the same as diving down a kilometer in the oceans here on earth.
Its surface is completely obscured by clouds of sulpuric acid and its core is so uniformly heated at this point that it cant sustain a magnetosphere any longer (convection is necissary) and therefore it relies on the mercy of solar wind not to blow its atmosphere off the surface.
Its also the third brightest in magnitude in our sky (following the Sun then the Moon) and can be seen best at evening and early dawn, this has led it to be thought of as two seperate bodies in prehistoric times refered to as the Evening and the Morning star's.
Whats interesting is that in a few hundred years earth may be a mirror image of Venus in terms of CO2 rich atmosphere and fatal temperatures.

And they don't even have muscle cars on Venus!

The name Wendy was invented by JM Barrie for Peter Pan. When he was a child he had a speech impediment and called his best friend his "fwiendy" which evolved into a nickname and eventually his play.
