mass

So, if the Moon really is formed from the conglomeration of debris created from the collision of another planet with Earth billions of years ago, how is it that as the particles combined, and the mass increased as a result, the orbit of the forming Moon didn't reduce increasingly to the point...

Some years ago I read The Elegant Universe by Brian Greene, and in that book he laid out a way of thinking about relativity that made things click for me like no other explanation had before. Professor Greene wrote that any object, particle, or photon, is always moving at the speed of light...

This question came up, in all things, during a Philosophy lesson I was in earlier today. We were discussing the nature of immaterial substances (i.e. Substances without mass) and how they couldn't affect the world. This was in relation to Mind/Body duality, specifically the 'Mind'. Anyway, I was...

At this stage, my vote is no.

I was recently re-reading David Bodanis' "E=mc squared". He explained somewhat vaguely how Einstein had discovered the link between matter and energy, and said that if you wanted to know more, you could go to Bodanis' web site and the full rationale for Einstein's conclusions would be explained...

A real "mass conspiracy" so to speak. Rather tedious reading, but constructive comments would be appreciated. Mass and Potential Energy of World Trade Center Tower 1

I have reworked my mass and potential energy calculation for WTC1. I haven't formally written it up yet but I include here images of my spread sheet and a description page. Thanks to Mackey, 3body, Newton, Dr. Greening and others for providing useful criticism of my previous calculation and...

http://tinyurl.com/h8nvf Australian Skeptics show, once again, that Homeopathy does not work. Before the 2004 convention, we marched into a Sydney Pharmacy, yes, a pharmacy, and bought almost $100 worth of worthless sleeping pills. Then, as you can see in the video, Richard Saunders, Prof...

As some of us who follow Dr. MAS's career with barely stifled giggles will know, he supposedly made a major presentation on the 23rd of April to a packed house. And what was the subject of MAS's presentation? I quote: Transmission of material doses from potency to another Not that you need...

http://news.yahoo.com/s/nm/20060118/pl_nm/rights_massachusetts_dc Will old mistakes be repeated? Will Frist keep his mouth shut? It will be interesting to see how this one pans out. Poor little girl. I highly doubt she had any form of living will. So what will be the breaking point in this...

Zimbabwe is in "meltdown" says United Nations humanitarian chief Jan Egeland following a visit to the country. He also said President Robert Mugabe's rejection of tents for hundreds of thousands of people evicted and made homeless this year is "puzzling". Some 700,000 people lost their jobs or...

I'm not really sure if I'm asking this question properly or not, as I'm not experienced in physics, but here goes: Does an infinitely large, or even better, any size vaccum, have a mass or a gravitational pull? I'm virtually illiterate in the study of physics, so where possible please respond...

For a class I am taking (it is called "Testing Psychic Claims") at UC Davis I am doing a group project on the "mass consciousness" effect, similar to what the Global Consciousness Project does (I'm sure you are familiar with them). I'd like to describe the experiment we are going to perform...

Does energy contain mass? If it does not, why E=mc&sup2?:confused:

http://news.bbc.co.uk/2/hi/americas/4161983.stm Does this idea bother anyone else? Kinda seems like the govt saying, "Voluntarily give up some of your privacy, or we might take it from you anyway." I think every one of the 790 men ought to refuse. That way the police can "closely check" ( I...

From the Article: It is particularly greusome to me as a father that people can be so personal as to put a handgun to a woman clutching her child or a child's head and squeeze the trigger. Link to CNN Article

http://www.cbc.ca/stories/2004/05/28/canada/hysteria_040528 A leading epidemiologist at the University of British Columbia says a suspected poisoning on a Vancouver bus earlier this week appears to be a case of mass hysteria. (snip) A suspicious passenger and mysterious pellets were suspected...

I was watching a show on Discovery Sci. last year. On the show their is a high mass planet(a rocky world the size of jupiter). I read that such a planet is impossible. Is it? If so, why?

Todays the first day for same sex marriage certificates to be issued. Funny thing I did not know. Mass has a 3 day waiting period for marriage. Not for guns. WHICH IS MORE DANGEROUS I SAY!!!!! (You can get a waiver ofthe waiting period bythe way.)

Put on your tinfoil hats and tie 'em on tight. The Tehran Times says: U.S. Unloading WMD in Iraq. Is this another October surpise in the baking? Stay tuned, but remember: keep it Hush Hush... ;)

Can anybody explain what the "mass hysteria" term used by skeptics means and how it is applied? The abstract above was from an article about the theories of ghosts. Whistler.

Folks ... remember the mass meeting/rally today. For those that can't make it I will have a report and images late on Sunday, if it doesn't turn violent. On the Politics and Current Events forum. We need your support on this important issue. It is important because it affects moi. Featured...

I just saw an ad for a movie on TV. The movie is named "21 Grams." The first line in the ad said, roughly, "They say you lose 21 grams when you die." I'm not sure but I think their idea is then when you die, you suddenly weight 21 gram less, which means that 21 grams is your soul (or whatever...

I hope somebody in-the-know will leek info to authorities so they can catch the rap-scallions responsible!

I have a dictionary that defines "center of mass" as: What does that mean? I know what center of mass is. What I'm curious about is whether the above definition, understood properly, gives some extra insight into the concept, or whether it is nonsense. (P.S. Hey, how about that? My 127th...

Looks like someone is trying a mass hack tonight via the the RPC service vulnerability. Make sure you're all patched up! The patch is here

Over the past few weeks my wife and mother-in-law have gone to church to say a pre-arranged mass for the mother of another couple. The mass is applied for, announced, and time is set aside at the church for people to attend. It got me to thinking about when I am dead. I am an atheist, have been...
