Bye Bye Einstein
This last post in the series explains why I believe it is time to say goodbye to Einstein, and why I look forward to how our worldview develops in the light of this CERN discovery of material superluminality. Continue reading

Why not Discard Special Relativity?
This second post in my series on the superluminality observed (or suspected) at CERN looks at why we cannot accept it.

Faster than Light
When they discovered particles going faster than light at CERN, they didn’t want to believe themselves. They were practically begging the rest of the community to find a mistake in this discovery. Why would they do that? This post and its follow ups will try to shed some light on this strange lack of faith.

What is Unreal Blog?
This post is an expanded version of a Web interview regarding my blog. It attempts to answer the question why I blog. And why one should take philosophy seriously. Seriously!

Ghost of Gravity
Some beliefs are superstitions, while some others are scientific theories. What exactly is the difference between them? Let’s listen to what Pirsig has to say about it. Continue reading

Only a Matter of Time
Here is an unreal look at the what and why of time. Why do we have a sense of time when none of our five senses can sense it? Continue reading
Half a Bucket of Water
When philosophers look at anything, it becomes a bit technical. Their technical analysis may sound boring and irrelevant. Here is an attempt to tilt things in their favor. Continue reading

Modeling the Models
Mathematical finance is built on a couple of assumptions. The most fundamental of them is the one on market efficiency. Is it wise to trust this assumption? Are there limits to it? Are we operating at the right scale to ignore the shakiness of the market efficiency assumption? Continue reading

Global Warming and the Flu
An unreal look at global warming. Are we a virus on the earth? And is the global warming a bout of fever? Published in the Singaporean newspaper, Today, on 1 Dec 2008. Continue reading

The Big Bang Theory – Part II
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

Chaos and Uncertainty
This article appeared in the Wilmott Magazine in Jan 2009, and talks not quite about the chaos and uncertainty of the last few months in finance industry can be summarized in two words. It is more about the physics concepts bearing the same names, and how they can be applied to the turmoil in the financial and economic world. Continue reading
What is Space?
This post examines the realness of our space perception. (Why did you think this blog was called Unreal?) Continue reading

Are Radio Sources and Gamma Ray Bursts Luminal Booms?
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
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
