A Stunning New Image of The Pillars of Creation

January 20, 2012

The European Space Agency’s Herschel Space Observatory released a stunning new image of the Eagle Nebula and the area of star formation known as the Pillars of Creation. The Herschel Observatory focuses on the far infrared spectrum and is capable of seeing the coldest and dustiest objects in space. In this image the observatory shows this well know Nebula in Spectacular color in detail in spectacular detail. The Pillars of Creation can be seen sticking up in the central-lower part of the image.  Thanks to the Daily Mail for the image and  article:

This image is taken from the x-ray and infrared spectrum as opposed to the Hubble image below that is in the visible spectrum.  Hubble’s picture was taken in 1995 and is one of the most famous images in the legacy of the space telescope.

In other space news be sure to check out the Hubble 3D film at your local IMAX theater (probably at your local science museum). Here’s a look at the trailer.

The Bouncing Universe

December 17, 2008

One of the hot new theories in theoretical physics is Loop Quantum Gravity (LQG).  The new scientist has an article, Did our universe exist before the big bang? that discuss this radical theory.  Basically it bridges the gaps between quantum mechanics and general relativity by proposing a that the fabric of the universe is woven from quantum gravitational field lines (yeah, read the article).

The idea of the bouncing universe had always made more sense to me than that of endless expansion and a energy death.  Basically we are talking about a big crunch with a rebound, they even talk about the possibility that not all information would be lost at the end of the contraction phase (we’ll see about that).

How would this theory work with the possibility of the multi-verse? Could this theory be used to explain reincarnation?  How would earlier and later universe differ from our own?  Lots of interesting questions to ponder.
