WD-40 stands for Water Displacement, 40th attempt. Name was coined by the chemist, Norm Larsen, while he was attempting to concoct a formula to prevent corrosion by displacing water. Norm\'s persistence paid off when he perfected the formula on his 40th try.
 
I guess light bounces off of different objects... and the frequency of the object could alter the "shape" of the light...

no its because gravity bends light.


my fact about 2 objects moving faster than light i will rephrase it

the distance between these objects has increased, if you work out the speed which they are moving apart, it is (lets say) 2.6x the speed of light

(this is to kill whoever said 2 spaceships go 0.6 light speed in different directions)

You cannot divide by zero :p

Zero was invented in India by Indian mathematicians dating as early as 5th century. They widely used it in calculations, astronomy and astrology. Zero was spread by Arabians to the Europe and there on it was spread all over. Before this, all Europeans used roman numerical which were difficult to calculate on as they were in the form of symbols, lengthy and had limits.

The first invention to break the sound barrier was the whip.

The slowest ever recorded constant speed of light was 38mph when it was shone through sodium at -272 degrees C. However since then scientists have been able to stop light by shining it through a Bose Einstein condensate of the element Rubidium.

The tallest mountain in the world is Mauna Kea in Hawaii, the highest (from sea level to the summit) is obviously still Everest.

about 50,000 years ago, humans spread across Asia and Australasia. 40,000 - 35,000 years ago, they moved into Europe. 30,000 - 25,000 years ago, they trekked out of northeast Asia and crossed into the Americas.
