 Turn Out the Lights
swansont writes: A New Push to Turn Off the Lights in 2009
Astronomers are fed up. One fifth of the world's population cannot see the Milky Way because street lamps and building lights are too bright. So scientists are mounting a new campaign, called Dark Skies Awareness, aiming to reduce light pollution as part of the 2009 International Year of Astronomy.

Milky Way Put On Weight this Holiday Season
swansont writes: Milky Way 50 Percent Larger, Astronomers Discover
[N]ew measurements of how quickly our galaxy is rotating have led a team of Harvard astrophysicists to conclude that our galaxy is 50 percent more massive than previously thought, and likely does have four arms.
"We should certainly think of the Milky Way no longer as the little sister of th… more» |
Belated Happy Perihelion
swansont writes: Calvin's dad is not a scientist, and the cartoon gets it almost exactly wrong.
He says it's colder because the earth's orbit is taking us farther from the sun.
The perihelion was Jan 4th, meaning we were closest to the sun then.
The seasons, of course, are caused by the axial tilt.… more» |

 Abiogenesis
... WOW.
Okay, let me give you a piece of advice. If you're going to summarize a scientific theory that evolved (oh yes, theories evolve too! ain't science cool) for a hundred years, and combine it with a mixture of theories from other disciplines (evolution is not abiogenesis), I think you...

Please offer a personal point of view on this, something to discuss. Pasting only the work of other is not the purpose of this forum.

Beauty: an evolutionary tool?
Right on. It'd be cool to see what you come up with. Another similar angle is how people are into the green/environmental movement. Much like having a high SES, those who have a strong awareness and commitment to the environment tend to do better sexually (at least, on college campuses, anyway)....

Why does the decrease in pressure cause the molecules of a gas to slow down?
This is fun. It is like the seven wise men and the elephant---each person tells a different aspect. of the same thing really.
I will tell you another way to visualize it. Imagine the gas in a cylinder with perfectly reflecting walls. To reduce the pressure, draw the piston back.

Mapping the universe in "real time"?
I was saying that you consider the forces that apply to the situation.

Let me guess that you are young because exponential growth of knowledge is apparent to me. However, I am old enough that I served in the Vietnam war. No reply to my last post indicates no...

Quantum Gravity
Martin -
thx for the response - I will surely take your suggestions as to contact persons...but, even theoretically, do you think there's a shot? I know that looking at graviton spin as a perturbable object is kind of out-of-the-box, but I haven't been able to figure out any shortcomings - what...
