Dark energy, dark matter, black holes and stretched light

New Scientist.com features an article on how dark energy, dark matter, and black holes may all be related. If this new idea holds true, what we think of as a black hole will be changed forever.

Black holes were once thought to be a star that collapsed on itself, becoming so dense that their gravity pulled in everything, including light. Nothing could escape.

That sounds simple enough, but the black hole theory is filled with strange possiblities. One of these theories was how light would become so enlongated by the pull of gravity that it might leave a "ghost" image...lingering at the black hole's edge forever.

This new dark energy theory could solve some of these problems, but it helps if you are aware of what dark energy is, and you know it has nothing to do with "The Force" from Star Wars.

The most mind-bending concept in the article is that our whole universe might be a giant dark energy star. How such a star would come into being...who knows?

I love it. It takes us back to the 'Horton Hears A Who' theory of the universe. My personal favourite.
