Constraints of Perception and Cognition in Relativistic Physics

This post is an abridged online version of my article that appears in Galilean Electrodynamics in November, 2008. [Ref: Galilean Electrodynamics, Vol. 19, No. 6, Nov/Dec 2008, pp: 103–117]
It can be viewed as a good summary of my book, The Unreal Universe, with all the gory mathematical details. Originally written for a professional audience, this post may interest my physicist friends, especially those with a philosophical openness in their beliefs.

The Philosophy of Special Relativity — A Comparison between Indian and Western Interpretations

11 of 12 in Popular

In this blog version of an article published in Omega, I discuss how Eastern and Western views say essentially the same things when it comes to the nature of space and time. And how that view can be interpreted as a basis for understanding Einstein’s theories. [Journal Ref: Omega – Indian Journal of Science and Religion, Vol. VI, (Dec. 2007), pp 138-150.]

Universe – Size and Age

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.
