Hi All,
I read the following article on a nasa website and they claim that the universe if flat with only a 2% margin of error.
I am aslo reading from reliable sources that the univers is football shaped or likened to a baloon.

Like to know some of your opinions on this.

Recent measurements (c. 2001) by a number of ground-based and balloon-based experiments, including MAT/TOCO, Boomerang, Maxima, and DASI, have shown that the brightest spots are about 1 degree across. Thus the universe was known to be flat to within about 15% accuracy prior to the WMAP results. WMAP has confirmed this result with very high accuracy and precision. We now know that the universe is flat with only a 2% margin of error.

Why do I keep imagining a similar scene 600 years ago with a bunch of people confidently proclaiming, with absolutely no doubt at all, that the Earth is flat? :blink:

The Earth isn't flat? What you talkin' about Willis?

:D Fall of the edge :D
This reminds me of Cosmos (TV Series), presented by carl sagan if my memory serves me , (it frequently doesn't) he used a 2 D universe, width and width, no height, Ahh I'm having nightmares, no such thing as up! I'm gonna fall of the edge :o

I didn't mention this before but this site is very tongue-in-cheek... I don't know what happened to the real Flat Earth Society, but I'm sure it's not these guys LOL

RE Cosmos... Sagan actually demonstrated how a Greek scientist named Eratosthenes proved the Earth was round several thousand years ago. And he got the circumference of the Earth right with only a small margin of error.

He'd observed that the shadows at noon in one city were shorter than in another, so he theorised that the light from the Sun was hitting the objects at different angles... he got someone to pace out the distance between the two cities, he measured the angular difference between the two shadows and from that he was able to calculate the circumference of the Earth.

I know how he did it, but I'm not explaining it very well LOL It's something anyone could theoretically do today...

For example, let's say it's on the Spring or Autumn equinoxe... the Sun would be directly overhead on the equator - ie, 90 degrees above your head. From the north pole, the Sun would be on the horizon - ie, 0 degrees above your head.

So you have the angular difference between the two shadows - 90 degrees. You know that a circle is 360 degrees. Dividing 360 by 90 gives you 4.

All you need to know now is the distance between the north pole and the equator (ie, 6214 kilometres)... you just multiply that figure by 4 (ie, 360 divided by the angular difference of the shadows, ie 360 / 90)

...and that gives you the rough circumference of the Earth 24,856km - . You won't get a truly accurate figure because, of course, the Earth is slightly flattened at the poles but you'll get a good estimate :)

The true circumference of the Earth around the equator is 24,901 km and about the poles it's 24,860 km. (http://geography.about.com/library/faq/blq...rcumference.htm (http://geography.about.com/library/faq/blqzcircumference.htm)

i direct your attention to Flat Earth (http://www.flat-earth.org). QUITE the crack up!
