Are Radio Sources and Gamma Ray Bursts Luminal Booms?

Posted on November 7, 2008 by Manoj

This post is the blog version of my article published in the International Journal of Modern Physics D (IJMP-D) in 2007, soon to become the Top Accessed Article of the journal by Jan 2008. Although it might seem like a hard core physics article, it is in fact an application of the philosophical insight permeating this blog and my book. 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 →
