I don't know much about it. Are they a religion-oriented group? I saw a model with the ice wall holding in all the water. I thought it was a joke at first. the idea is interesting, but the only ounce of doubt i have that they are not totally insane is our lack of true understanding of gravity. what do you think about it? any merit to their claims?

I actually think it happens.

I mean, the time goes so quick till the minute we wake up. Time flies when we sleep.

Aren't we actually traveling through time?

I been reading an article about an asteroid, Apophis, that may pass, just barely hitting Earth in the year 2029, then possibly entering a gravitational "keyhole," shifting its orbit far enough to make it strike Earth in the year 2036.

My question is what exactly is a gravitational "keyhole"? I've tried to google it, wikipedi it, my research was unsucessful. The only answer I've found that it is some sort of imaginary hoop in space.

substanstial food supply for all of us as well as the animal kingdom? This is excluding any natural diasters and the possibility of a panademic or some space debris hitting us. Does this rattle your cage? Whats the chance of something like this happening within the next 50 yrs? I predict it will happen b4 then not to mention some nut who wants to send a few big bombs into us wiping out life as we know it.This is not ask to scare people but is ask to make people realize how vunderable we really are ..We really have control over very little do we?

Ok so I've heard prolly 10 different reasons why ppl think the world will end in 2012. But my question is....whats the hype? I mean why do ppl think that an alignment of the center of the galaxy and our sun would end anything! It makes no sence and just doesn't add up!

So apparently that's why the Mayan Calandar stop on Dec 21, 2012, cause because of a polar shift, they can no longer make the calculation.

At this date, the earth and sun, will be in a perfect alignement with the center of our galaxy (something happening only once every 26000 years).

Apparently this will cause major problem with our planet, a possible polar shift. Do you believe in that ? It has been proven that earth poles shift on several occasions before and they will do it again.

Read my question carefully because it's difficult to explain. I'm in the northern hemisphere (about 35 degrees north lattitude). Late in the evening (Halloween) I saw the moon was up about 45 degrees. It's a half moon. What's weird is that the line between the dark half (top) and the light half (bottom) wasn't parallel to Earth's horizon. I would expect the sun to be south to the equator so the line through the moon would go from the top right (left is Earth's north) to the bottom left. Instead, it was the other way as if the sun was even farther north than I am. Why is that?

since stars are born in molecular clouds. Is our solar system in or near a molecular cloud?

I don't know if the stars that make up the dippers are near each other or just line up because of the position we view them from. Since interstellar travel is likely an impossibility perhaps an advanced alien civilization sent the only message it could by spawning suns in a pattern?

I firmly believe that extraterrestrial races have been visiting earth for thousands of years. I have read hundreds of accounts of contact, and carefully reviewed transcripts of radar showing impossible aerodynamics. There are thousands of documented cases, each with hundreds of witnesses. It can't all be a hoax or mistaken identity.

However, when it comes to stories of human contact with aliens, something doesn't seem quite right. I have never read about aliens being fascinated with our culture. You would think that they would comment about the astounding array of human arts, everything from sculptures to modern painting. If aliens really have had contact with humans, why have I never read any account of their impression of our culture?

Also, unless there is some "Prime Directive" about non-interference in another culture (ala Star Trek), why has no alien ever offered some new technology to help make wars obsolete?

Something seems to be amiss. What is your opinion?

If the earth has great mountains, such as the Himalayas, in some places and great valleys, such as Death Valley etc. in other places, how does it appear perfectly round and why do all the planets in our solar system appear perfectly round?

A comet with an elliptical orbit with one focus at the sun. The maximum distance to the Sun (aphelion distance) is rA = 5 x 10^9 km. The minimum distance (perihelion distance) is rP = 5 x 10^7 km. Find the speed of the comet at the perihelion position.

I have heard that the sun is apparently expanding and will eventually burn all life on earth. In that context, should govts seek to colonise and find other planets that can support human life?
