Science & Mathematics - 26 August 2007

I was wondering what is the most accepted theory on what the shape of the WHOLE universe is? I have heard it is a globe shape much like a planet, I have also heard that if you were to look at it from a distance it is like a sheet of paper. And I have even heard that it is ever expanding in 360 degrees. Which is the most accepted?

Is there a good website or video that clearly illustrated an unbiased view of wiether or not we landed on the moon. Or any good information that someone has compiled from researching this. I have always wondered if this rumor were true.

There've been questions lately about the Moon and Mars appearing as twins in the sky lately. I took them to mean a conjunction of the two. Even answered one on that basis.

But it occurs to me that an eclipse of the Moon is coming. When totality occurs, the Moon is often reddish colored. Are these folks claiming that this red Moon is actually Mars, somehow very near?

Is that what this is all about?

A friend of mine told me this.... I dunno if it's really real, but if it is, I think I'll check it out!! :) I'm gonna be working all night tonight so I thought I'd be sure and take a smoke break at about that time...:)



27th Aug the Whole World is waiting for............. Planet Mars will be the brightest in the night sky starting August.

It will look as large as the full moon to the naked
eye. This will cultivate on Aug. 27 when Mars comes within 34.65M miles of earth. Be sure to watch the sky on Aug. 27 12:30 am. It will look like the earth has 2 moons.

The next time Mars may come this close is in 2287. Share this with your friends as NO ONE ALIVE TODAY will ever see it again.

What about with constant speed?

Theoretically, and if you were going slow enough, I'm sure you could keep your velocity and speed constant. Or am I missing something fundamental?

If you have a circle, you put a dot in the middle and call it O
Then you draw a straight line from one end of the circle through O to the other side, and you call one side A and the other side B.
BA is the Diameter
OA is the Radius
O is the Circumference

Is this correct?
