Science & Mathematics - 22 August 2006

I've been looking at what some people think Extra-terrestrials would look like. But I have to think, is it really possible to imagine, realistically, an alien species? To think they would be made of the same elements is, of course the obvious topic, but is it very plausible that any other organism would evolve or develope in any way like Earth's? Things like DNA, Cellular resperation, Cells themselves, Photosynthisis(sp?), and many other things we use to recognize what organisms are. So yes, this is less a question and more of a spring-board for disscusion.

Did we really walk on the Moon?

I just read an article that brought up some really good points:

The flags planted by the astronauts appear to be wave in the wind when the moon is supposed to have no atmosphere.

In some photos, shadows point in different directions as if there were more than one light source.

The astronauts seemed to be unable to jump more than a half foot even though gravity on the moon is only one-sixth that of earth's.

There is no fog on the film from the immense temperature variation from the warm landing module to the freezing or sizzling hot temperatures on the surface on the moon, no discoloration from passing through radiation belts.

No stars seen in the pitch black sky lunar sky, stars that should have appeared brighter than anywhere on earth.

I often wondered how back in a time when computer technology wasn't even invented, we so easily walked on the moon. Now with all our technology we have never attempted to do this again.

Did we really walk on the Moon?

How can you measure the speed of light yourself?

I have read about Armand Fizeau used a rotating wheel, And Albert Michealson's device, but nothing that i have read has given real exact instructions how to construct a device that could do it. I am not looking for accuaracy as much as i am consistancy. Dont bother giving me a post saying its not possible, because it is. I just want some brilliant mind to explain how the different machines worked, and how i could build one.
