Cosmsology and Blackhole/Space travel articles

Post by Arrow »

This article is on the inflationary theory:
http://www.spacedaily.com/news/cosmology-03k.html

And this one is on the possibility of singularities being different than we currently think, and the possibility that they might be use for space travel:
http://www.spacedaily.com/news/blackhole-03c.html

Both are from SpaceDaily.com

Thoughts? Comments?

Hype with little content. Typical SpaceDaily. No mention of how such singularities occur or what they are.

Also wrong. Their claim that inflation "expanded ("inflated") to a size trillions of times bigger than what we can observe today" is poppycock; astronomers have a pretty good idea of what size the universe inflated to from studying the Cosmic Microwave Background and it is a good few orders of magnitude smaller than todays observable universe. It DID expand the universe to trillions (and more) times its hypothetical pre-inflationary size, but that isn't what they said.
There is a little good info on WMAP, but there is plenty out there that's better.
My black hole knowlage isn't comprehensive enough to pick apart the second article, but it smells a little bit off also. Nothing that jumps out at me like the first article, but black hole geometry is weird, and easy to misunderstand if you aren't reasonably knowlagable.

I may have posted this link before, but here is the Black Holes and Relativity website of Andrew Hamilton, an astrophysics professor at my school. As you would expect, it has accurate (for when the webpage was made, at least) info on black holes, relativity, and links to other good pages on cosmological stuff. link is http://casa.colorado.edu/~ajsh/home.html

Well since SpaceDaily is full of BS, any one have a link to a site that keeps up with the latest in cosmology (and perhaps other space news) and writes layman understandable articles?
