So you know how all those "smarty-pants scientists" say that the universe is constantly expanding? Well anything outside earth is the universe and it goes on forever you know? Well if it is constantly expanding, where can it expand to? There is nothing beyond it....HA NO SO SMART NOW ARE YA SUCKERS!

According to Conrady's standard a 70mm achromatic refractor must have f/14 - many are close to this.But a 125mm aims fot f/25 and 150mm - f/30!!!
The big achromats on the market are f/10 - f/8 and they cost hell a lot of money and if that above is right they should perform way worse at the same magnification and you would be better off with the mid ones and is that the case???Sure not!
If chromatic aberation is caused by rays falling at steeper angle and thus get more refracted then if the f-ratio is kept same it's fine.The only possible explanation I see comes from the fact that a bigger f/10 refractor will give more magnification with same eyepiece than the smaller refractor so if the smaller one is given such an eyepice (to reach that mag.) It will suffer the same chromatic aberration at f/10 but because of diffraction and other optics limitations it will be out of the question to detect it in so deteriorated image.

If you watch high altitude balooons, they just float into the upper atmosphere. Gravity does not hold them back. Can't we use a slower, gentler means of thrust to lift satellites and space shuttles into orbit? Just trying to think outside the box here... What would keep a ship from breaking out of orbit at a very slow speed? It seems this would be much safer than strapping a highly explosive fuel tank to the capsule.

I'm thinking this may happen, because you can say that the Earth and moon are one body becuase they are connected by gravity, and so if the body suddenly lost a lot of its mass, this would decrease the Earths momentum, and so our balanced orbit around the Sun would be lost, and we'd begin falling towards the Sun... is this correct?

... was going on a trip. And on its way back (approx 2 years) it would do a fly by of the moon landing site close enough to take photos, as obviously the flag and equipment would still be there, and there by prove or disprove conclusively the moon landing! Any body know anything about it?

do you think they exist, and one day we'll be able to find away into them.

I remember reading something a while ago about how the massive black hole at the center of our galaxy creates an extremely thin disc that streches throughout our entire galaxy and we will be passing through it sometime in 2008. Does anyone know what this is called or a website that can provide me with more information on it?

I figure that everyone should be able to go into space if they wanted to, but N.A.S.A. doesn't let civilians go into space, why should N.A.S.A. get to hog all the trips into space?

The Milky Way is not a constellation, but a bright band of stars that stretches across the entire night sky. The Aztec Indians called this part of the sky "Centzoni" {which means many, many because there are too many stars to count.
