  1. Then please do that, because all of these threads about how smart you are have become very tiresome. This is a science discussion forum. If you want to discuss science, please do so. If you want to discuss how you intend to save the world in a few years, please do it elsewhere.
  2. Galindo, please stop going around bragging how smart you are without anything of substance to back yourself up. This is going nowhere. I think six pages of "I think I have an amazing idea" is quite enough.
  3. That is quite enough. Flaming is not necessary.
  4. I'm sorry; I don't seem to have received the mail. Could you please resend it? I do hope I didn't break the mail system. I tinkered with it a bit yesterday and perhaps something went wrong...
  5. If so, could you please respond directly to the email I sent to your University of Idaho address? I can see that you are who you say you are, and I'd like to help in any way possible. We do not promote fraud here. We can discuss what measures should be taken and any other details via email.
  6. Hmm. CO, per mole of gas, has: 12g of C 16g of O In total, that's 28g for each mole of CO. 12/28 = about 43%. In CO2, there's two oxygens, so it's 44g total. 12/44 = about 27%. So if you work it out by mass, the numbers are right. If you do it by numbers of atoms, they're wrong.
  7. Funny you'd say this, seeing as you are gafferuk. Could you kindly cut out the ban-evasion? This is your third account that I know of.
  8. You'll want to read the second link I gave, then, since it specifically is about evidence for macroevolution. Also, this post that I made recently.
  9. Why should macroevolution occur without species changes? Macroevolution means large changes in characteristics in an animal, and if enough build up, it's a different animal.
  10. I'm going to do a little audit some day of forums we should add or remove. This'll be on the list to add.
  11. http://talkorigins.org/faqs/homs/ http://talkorigins.org/faqs/comdesc/ There's plenty of evidence for evolution. See above.
  12. You should try to beat this beast: http://www.potrocs.org/pics/aurora/index.html
  13. We should be able to use the equations to make a Total Perspective Vortex.
  14. The distance from the thing it's orbiting. That's all. Far planets go slow, close planets go fast. Size doesn't enter into it, as I'll show you below. So, [math]F= G \frac{m_1 m_2}{r^2}[/math]. And [math]F = ma[/math]. If we make the planet [math]m_2[/math], [math]F = m_2 a[/math]. So: [math]F = m_2 a = G\frac{m_1 m_2}{r^2}[/math] Cancel out [math]m_2[/math]: [math]a = G\frac{m_1}{r^2}[/math] The size of the planet doesn't enter into it. It doesn't matter. Your OpenOffice calculations must have had a small rounding error or something -- the math it uses will only be precise to so many decimal places.
  15. Everything falls at the same speed, regardless of how big or heavy it is. Did you imagine the circles as I told you to?
  16. But if you're going sideways fast enough, you miss the Earth entirely. Imagine an object above Earth going very, very fast sideways. Gravity pulls on it. The object continues going sideways, but it's also going down a bit. Gravity continues pulling on it, so the path starts looking like a circle -- sideways and down. If you go too slow, you eventually fall into the ground, going both sideways and down. But if you go fast, the path you take looks like a circle that's bigger than the Earth. You go right around. Imagine that path in your head and what happens as you go faster and faster sideways.
  17. Nope. You're not listening. The Moon is actually getting farther away from Earth as it orbits. Gravity doesn't slow down things in orbit, if they're in a circular orbit. They're going sideways, not up or down. It just pulls them into a circle.
  18. If you're just sitting, you'd fall right back onto the seat. Now, if you were in orbit at 17,000 mph, that would be a different matter. Take a look at my earlier post about strings and balls again.
  19. True. They are falling. They're just going so fast sideways that they miss the Sun entirely, and go around in a circle. Nope. You're still being pulled on by gravity. Think of it this way: Imagine you're in an elevator. The elevator starts going down. Because it's accelerating down, you feel lighter, right? For a moment while it speeds up you feel light. Gravity's still pulling on you just the same -- it's just that the floor isn't pushing up on you as hard as it used to, since it's going down. Suppose someone cut the elevator cables and it starts falling. The elevator car starts falling as fast as gravity can pull it, and so do you. So the elevator and you are falling down at exactly the same speed. If you jump, you'll end up floating in the middle of the elevator, since it won't "catch up" with you and hit you. Same goes in space. You and the spacecraft are pulled on by gravity, and there's no resistance. There's no ground to push up on your feet, or up on the spacecraft. So you appear to float.
  20. Most planets won't eventually hit the sun. Read my earlier post about the ball and string. In fact, the Moon is actually getting several inches farther away from the Earth each year. Remember, the planets are going around the sun, so the Sun's gravity just pulls their paths into the circle. If there's something going in a straight line, and I hit it on the side, it keeps going forward at the same speed but now also goes sideways, right?
  21. Here's the deal with escape velocity. You know how you reach a certain speed if you fall from a certain height? (Ignore air resistance.) The higher you go, the faster you're going when you hit the ground. Now, suppose you're reeeeallly far away from Earth and you start falling towards it. You'll have a certain amount of energy/speed when you hit. In fact, you can calculate that energy all the way out to infinite distance away from Earth, and it's a finite number. (You won't hit the Earth with infinite speed.) So as long as you launch with an energy greater than that, the Earth's gravity will never be able to take away all of your energy.
  22. It'll slow down. It just won't slow down enough.
  23. Imagine having a piece of string with a ball on the end. Swing it over your head. The ball goes round and round in a circle. Now, the string's pulled tight, correct? And it stretches from the ball to the center of the circle. So it's pulling the ball in towards the center of the circle. If there was no string, or if it was cut, the ball would fly off in a straight line, but the string provides a force that pulls the ball into a circle. If the string pulled twice as hard as it needed to, or the ball went too slowly, the ball would fall towards the center of the circle. If the string were too weak, the ball would go flying off again. That's how orbit works. Gravity is the "string" that connects something in orbit (the Moon, a space station, whatever) to the Earth. If the space station isn't moving fast enough, gravity pulls it in to Earth. If it's moving too fast, it flies off into space. Here on the surface of the Earth, we're hardly moving at all.
  24. Most colleges are need-blind: they don't care whether you can pay when you apply. Most will give you grants and loans to make up for what you can't pay. Don't be defeatist. Go out and get things done. Yesterday.
