Why do we need humans to collect and send data from outer space when we can just send light signals and interpret the data?

Why doesn't NASA send LASER or robots or machines instead of humans on space missions?

"Science n. systematic knowledge of the physical or material world gained through observation and experimentation."

How can one "observe" something that supposedly happened millions/billions of years ago?

I am a creationist, but I don't run around trying to say that creation is a "science" because it can't be actively observed. One can see evidence of it, but anyone can twist evidence their own way to say what they want.
It just irritates me that people of any sort try to pass off microevolution as being a "science" when it's unobservable. If we evolved from monkies, why are there still monkies around? wouldn't they all be humans?
I just wish that schools would put more stress on evolution being a theory as opposed to fact.
And I wish those people with the darwin-fish on the back of their cars would evolve themselves some working eyes and some more brains, they still seem a bit too much like primates to me.

I have heard that Roger Lenard expressed an interest in testing Heim Theory using the Z Machine at Sandia Labs. Will he or others run an experiment soon?

I just tell my students that because the sun is fluid, it spins at different speeds. I'm always hoping they don't ask for the physical explaniation.

Somewhere in south china (?) squirrels natural food like nuts, seeds and berries is so low they've started hunting in groups and attacking stray dogs, killing them and eating bits of their flesh!!!

Are squirrels omnivores then?? It's new to me. Doesnt it sound scary??!

This is (probably) the same size as 2 chessboards full of rice in a pattern of powers of 2s. So it starts of as 2 grains of rice on the first square, 4 on the second, 8 on the third, 16 on the fourth, 32 on the fifth, 64 on the sixth, etc. etc.

This is a bit of an odd question but a debate in my household for a while. Are you suppose to wait until the microwave stops beeping for all the harmful radiation to disappear before taking out something that you have just warmed up? Or does anyone know the real purpose of those extra few seconds of beeping after the timer has gone off?

You know how people say, women who are so specialized in medicine might not be able to manage their career and their family at once...I was wondering if that was really true.

Each letter in the word 'spearmint' has a value. By adding the value of the letters together compute their total.

CLUES

R A N x T I M = 279,823,411,864.

(rain=270, spin=181, taint=275, near=200, and pine=188

There is low water pressure in the house, about 25 psi. When taking a shower the water never seems to get hot. The showerhead has a 1.5 GPM flow restrictor in it. Is this adding to the problem of the hot & cold water mixing?
