Is there any where in the universe that would not have any atoms?

Or is that the definition of space...that it has things in it?

UFOS: SECRETS OF THE BLACK WORLD Area 51 in the U.S. State of Nevada - also referred so as "Dreamland" is the most secret military test site in the world. Insiders claim that even recovered spacecraft from an extraterrestrial civilization are back-engineered and test flown here. Indeed, over the years hundreds of witnesses have observed strange maneuvers of disc-shaped craft over the "Black World" of Groom Lake. In a three-years investigation, a German film crew dove deeply into the secrets of "Dreamland", interviewing top scientists and security personnel who worked inside Area 51 and claim to have seen the recovered discs and even alien life forms -"guests" of the U.S. Government! And finally they captured on film the remarkable maneuvers OF THESE MYSTERIOUS UFOS... 135 Minutes. PAL Video. NLG 70.00 o Euro 31.90 o £ 21.90. Code: UBWV

UFO ABDUCTIONS A Global Phenomenon Over 4 million Americans believe they were vitims of the most frightening aspect of the UFO phenomenon: Alien Abductions. In this breathtaking documentary both, witnesses and internationally respected researchers, reveal the evidence. And they demonstrate that the closest encounters happen all over the planet: *Strange implants of an unknown technology were surgically removed from an abductee's body in the U.S.. *A British policeman in Australia was abducted by small aliens - and photographed one of them. *Two couples in Australia met for the first time during an abduction aboard an alien spacecraft - and later recalled their experience under hypnosis. *Strange landing marks and magnetic anomalies found on the ground after abduction experiences. A man from Nazareth suffered from severe inflammations after being covered with yellow dust during an abdcution. 78 Minutes. PAL Video. NLG 70.00 o Euro 31.90 o £ 21.90. Code: UGPV

Where is all the missing antimatter? Instead of doing a dance and positing near total mutual annihilation after formation of both leading to today's matter universe, could time reversal really mean something here, and the antimatter produced be moving in the reverse direction? Number lines in one dimension can extend both before and after zero point. Spatial dimensions extend on both sides of any reference point one defines- why not time? And in a spacetime closed universe these two ends will meet- so time too? If so, then antimatter will be coming at us from the 'future' which is also before the past. What little we see today in cosmic rays may be partially all that's left after future annihilations, which will have eaten the bulk of all matter and antimatter (but not today).

Of course this scenario requires a little fuzziness about the time between the Bang and matter formation. Unless there was some sort of linkage through the singularity to the other side, now lost.

Thoughts?

From a 100% stationary observer existing outside our Earth, solar system, and galaxy, how fast would a person standing on the equator be traveling through space?

Earth's equatorial rotational speed is 1041.666mph + Earth's orbital speed around the sun is 66,660 mph + .... + .... = ?

I guess I need to learn how fast the solar system rotates/orbits within the milky way, and how fast the milky way rotates/orbits within the entire universe, to get the final answer.

Ok, I have a grade 11 physics question that I really need help with. I can't ask my teacher because it's an assignment and he won't answer any questions and I can't ask my classmates because we each have a different assignment.
I've been sitting here for very long trying to figure out but I'm getting stuck at parts and I'm getting cramps and aches because I can't figure it out.
I'm asking for someone out there to please...if you have a little time...help me out. If you can explain them to me as to what I have to do, scan your answer back to me or just any sort of help would be appreciated.
So, if you like physics please answer this question and please give me your email address so I can send it you..only 1 question.
And my email address is: ashamon32@aol.com
If anyone out there can help me, you have no idea how much stress will be taken off my back. Thank you.

Why are silicon wafers always circular in shape?. Is it because it has least wastage after etching the dies?. I see that we have a die, the edges of the circular wafer are always covered with partial dies. This is a lot of wastage, so why not the wafers be rectangular or squarish. I beleive there will be more wastage of die space if it is squarish/rectangle. Please confirm this.

If there is any other reason please let me know.
