Cosmological Recycling

This will be a multi-part post,

When people get together to discuss how scientists believe the universe began the most powerful example is something called the Cosmic Microwave Background Radiation (dubbed the CMBR). Many scientists believe the CMBR is the leftover "echo" of the extreme temperatures that occured towards the beginning of the universe. What it really is, as far as most of us are concerned, is a very slight amount of heat (or just energy, however you want to think about it) that exists everywhere in the noticable universe. The first two images at the top of this article refer to the time periods of expansion as the universe began to cool, I will discuss these at greater length later. Whats most important to us is the third picutre, that is supposed to be a picture of the entire viewable universe done in the levels of temperature. Blue areas represent the great expanse between galactic clusters (large groups of galaxies) and the warmer areas represent the heat generated by those clusters.

So to summarize all this stuff,
There is a level of heat or energy that exists everywhere in the universe, even in the space between stars and galaxies, and many believe that this is the leftover radiation (or heat/energy) from the expansion of the universe. It is hard to deny the reality of the CMBR but it may not mean quite as much as modern scientists believe, more on that next time in the Laymans' Laboratory.

  4. I'm really happy someone is writing about this. I study astrophysics (not academically) constantly in my free time and love it. I'll add your blog to my list of sites to visit for reading. Be sure to check out my blog (how-do-they-do-that.blogspot.com) if you are interested.
