Well I was on a boat and the boat was going in...um...lets say west. And I was going to the opposite direction (East). So in going the opposite direction as the boat i go faster and if I walk in the same direction as the boat is then I'll go slower. (Remember that this is just a theory)

I have thought about this for years and no one has been able to give me an awsner. All this talk about evolution and creationism. I just want to know how all this stuff just appeared. I know how the universe was fromed by the big bang. But where did that stuff come from? For creationists who say god created it then where did god come from?

Here are some example awsners
MOM : God just is there should be no questioning it. We were not meant to understand.

Nope sorry mom doesnt cut it

Biology professor: Well were not quite sure yet but we will soon figure it out.

Nope doesnt cut it

Many other people: Just dont worry about it or think about it. Who cares.

Nope sorry I have to.

Anyone else have a better awnser to help relive me of my pain.

and 1/4 across the middle and about a quarter of an inch across the ends. It's made of a smooth, shiny gray metal. It's round like a cylinder that tapers toward both ends. There are no seams or holes or anything that would enable it to be attached to anything else like a fishing weight would have. It weighs about 2 onces and I noticed when I put it on my metal postal scale that it's magnetic. I asked some people in the park if they knew what it is and no one did. One woman looked at it and said "I don't believe in that." and fled. Based on the knowledge I gleaned from 1950s sci fi movies I would have to say it's from another planet in which case I can't believe in it either. It's very attractive object, pleasant to touch. I hope it isn't toxic or explosive. Anybody know what it is?

I usually don't answer many questions in physics, I passed my only phsysic class and then forgot everything. But I was wondering is there as many anti-Bing Bang creationist questions/answers here. Because in Biology there is always a creationism/evolution question. Also why is it that many are not enraged over the Big Bang as they are evolution. Could it be that evolution is taught more in school? because i dont remember learning much about it. What i learned about it came from wikipedia on my own research. So whats your thought on this?

So scientists say that 65 million years ago, a giant asteroid 10 kilometers across struck just off the coast of the Yucatan Peninsula.

Have we found pieces of this theoretical giant asteroid, or would have been obliterated on impact?

With such a force of impact, would it have thrown the Earth into our current orbit and maybe alter the tilt of the Earth? If so what kind of orbit did the Earth previously have, and would it have had a different climate?
