- curios, on 10/12/2007, -0/+3I like the way this website has a list of further information on the scientists and professors who are contributing, unlike many other science websites which only focus on there work and results and not the people who are creating these discoveries and ideas.
It is more respectful.
Much of the research that can be summarised on one page, is often the fruits of a lifes work, both studying and experimenting, and overcoming many failures and hurdles to achieve these successes.
Each one could tell an intricate and fascinating personal story. - alexkorova, on 10/12/2007, -0/+3I've read parts of the book, and it's... nice. Except it's filled with wrong math and other errors.
"The paper that Lerner cites as evidence for a lack of dark matter, Valtonen and Byrd (1986, ApJ, 303, 523), claims that the Coma cluster of galaxies and the other great clusters of galaxies are not bound objects. However, the observed velocities within the cluster would cause them to disperse in much less than the age of the Universe, so this claim is quite strange. Furthermore, the X-ray and gravitational lensing evidence now available show that Valtonen and Byrd were incorrect." - http://www.astro.ucla.edu/~wright/lerner_errors.html
Was too lazy to write something myself, but you get the point. Doublecheck alot of things written in that book, becouse alot is just plain wrong. - curios, on 10/12/2007, -0/+1Have astronomers considered the light in a galaxy as a possible source of hidden energy/mass, as much of the light is invisible - it's not coming towards us - thus it is dark matter - unseen.
Also, on average there are about one supernova per century in a milky way sized galaxy which can emit more light than all the other stars combined, we don't see this light until it arrives, yet it is still there and part of the mass energy of the galaxy. Over the course of a few hundred thousand years, there would be the energy equivalent to a few thousand supernova in photon energy travelling through a galaxy - all of it unseen; dark! - tdawson2012, on 10/12/2007, -0/+1Pretty awesome stuff man. Maybe its just hype but it seems like theoretical physicists are closing in on some of the fundamental mysteries of the universe, not to mention a unifying theory that could end the mystery altogether.....well in the next few decades anyways.
- Spamiclese, on 10/12/2007, -1/+1Dark Matter does not exist. Check out the book by Eric Lerner entitled "The Big Bang Never Happened". He breaks down all of this pseudo-science with hard facts and scientific data. He systematically disproves all of the aspects of the Big Bang Theory, including Dark Matter. It is a wonderful read for anyone interested in science. You don't need a degree in anything to understand this book.
- toddsherman, on 10/12/2007, -0/+0Yeah, that's pretty wild that they have all their contributors listed. Neat site.
FYI: Only about 4% of the total energy density in the universe (as inferred from gravitational effects) can be seen directly. About 22% is thought to be composed of dark matter. The remaining 74% is thought to consist of dark energy, an even stranger component, distributed diffusely in space.
