BEC = Dark Matter?
|
|
The last post in this community was over a month ago, so I figured it was time to spice Shuzak up with some neat physics.
As I was trolling www.arxiv.org, I came across this paper: http://www.arxiv.org/abs/0705.4158 . It discusses the possibility of Bose-Einstein condensate(BEC) as being what is behind dark matter. I personally think this is a great idea since I don't quite buy the whole WIMP thing. I like stuff that we can at least understand to a point.

Apparantly liquid water discovered on mars.
|
|
http://space.newscientist.com/article/dn12026-mars-rover-finds-puddles-on-the-planets-surface.ht
From Digg, the rovers found what appear to be puddles of liquid water (though some say they are just very clear ice).
It is my opinion, that it might well be liquid judging by the apparant erosion shown in the photograph, as well as the lack of surface traits (scratches, cracks, discolorations, etc. indicative of ice.
If this is the case, then ther...Click Here | By Ati

This is the way the world ends / This is the way the world ends / Not with a bang, but a whimper.
Thank you Mr. Eliot, but I beg to differ.
Ran across this article the other day and it made my head spin that it even got published. Compare and contrast with ...Click Here | By zenmonk

Hubbles replacment unveiled.
|
|
Nasa has revealed the James Webb Space Telescope. The new telescope is much bigger, much shinier and provides a huge improvement over Hubble. A combination of its much bigger primary mirror, its placement at lagrange point 2 and its sun shield will give it vastly greater sensitivity. ...Click Here | By poss

Dark Matter Found?!?
|
|
It looks like Hubble has found dark matter! Nasa has announced a press conference to discuss the apparent discovery of a ring of dark matter in the cluster CL0024+17. If this is true, it will be the first actual sighting of dark matter. ...Click Here | By poss

Dark Stars
|
|
a group of scientists have put forward the idea of dark stars these as yet theoretical stars could be powered by dark matter reactions rather than regular fission. The team put forward a few alternate theories on the life cycle of these stars, one of those theories these dark stars could have survived since the beginning of the univer...Click Here | By poss

Blank Sun
|
|
I saw this on Spaceweather.com ... its pretty awesome.
BLANK SUN: The sun is entering its 11th day in a row with no sunspots. This marks the longest string of blank suns since 1996. That was a year of deep solar minimum, featuring blank intervals as long as 37 days. 2007 is shaping up to be the same--a deep nadir of the solar cycle.

Full Moon
|
|
Have you guys noticed the moon the last couple of nights to be unusually small? It's a little weird... It might be because the moon's orbit is an ellipse not a circle... mayyyybeeee it was at its farthest point. but im not sure. it might be something else. does anyone else know?...Click Here | By Lacey

Pluto Occulation
|
|
On sunday morning (march 18th), Pluto will pass directly in front of a star in the constellation Sagittarius. This occultation will be visible through large backyard telescopes in the western & central United States. (It will also be visible from northern and possibly central Mexico & southwestern Canada.) You'll be able to have a rare look into Pluto's ...Click Here | By Lacey

320 EeV?!?!? (paper discussion)
|
|
This is an experimental thread. There is an article available on arXiv (www.arxiv.org), numbered astro-ph/9410069v1
it is about a 320EeV event detected by the fly's eye observatory in utah. this is an ENORMOUS amount of energy - a particle with a momentum literally equivalent to a major league fastball. the paper is entitled "in search of a source for the 320 EeV Fly's Eye Cosmic Ray".
i am currently in the process of reading this paper, i would invite interested...Click Here | By jared.nance
