The Big Bang Theory – Part II

Posted on November 20, 2008 by Manoj

This post is a continuation of my earlier musings on the Big Bang theory. This one looks at the foundational assumptions of quantum gravity. In management speak, it is a high level overview, which sounds like I understand it. In a physicist’s lingo, it is merely a layman description or a hand-waving argument. In other words, the management types out there may like it better than the smart ones. You be the judge! Continue reading →

The Big Bang Theory

Posted on October 21, 2008 by Manoj

People present the Big Bang theory in physics pretty much like Evolution in biology. But I feel that it is disingenuous to do that. To me, it looks as though the Big Bang theory is so full of patchwork, such a mathematical collage to cook up something that is consistent with GR that it is hard to imagine that it corresponds to anything real. Here is a short list of my trouble with the theory. Continue reading →

Universe – Size and Age

Posted on March 26, 2007 by Manoj

I posted this question that was bothering me when I read that they found a galaxy at about 13 billion light years away. My understanding of that statement is: At distance of 13 billion light years, there was a galaxy 13 billion years ago, so that we can see the light from it now. Wouldn’t that mean that the universe is at least 26 billion years old? It must have taken the galaxy about 13 billion years to reach where it appears to be, and the light from it must take another 13 billion years to reach us. Continue reading →
