Today's preoccupation with physical theories of everything takes a wrong turn from the purpose of science - to question all things relentlessly. Modern physics has become like Swift's kingdom of Laputa, flying absurdly on an island above the earth and indifferent to what is beneath.
Amazingly when you add life and consciousness to the equation you can actually explain some of the biggest puzzles of science.
We have failed to protect science against speculative extensions of nature, continuing to assign physical and mathematical properties to hypothetical entities beyond what is observable in nature.
Modern science cannot explain why the laws of physics are exactly balanced for animal life to exist.
Our science fails to recognize those special properties of life that make it fundamental to material reality. This view of the world - biocentrism - revolves around the way a subjective experience, which we call consciousness, relates to a physical process. It is a vast mystery and one that I have pursued my entire life.
In fact when you combine stem cell technology with the technology known as tissue engineering you can actually grow up entire organs, so as you suggest that sometime in the future you get in an auto accident and lose your kidney, we'd simply take a few skin cells and grow you up a new kidney. In fact this has already been done.
I do not think that there is a reputable scientist on this planet who would advocate using this technology to generate a human child as was just announced.
I think it's science and physics are just starting to learn from all these experiments. These experiments have been carried out hundreds and hundreds of times in all sorts of ways that no physicist really questions the end point. I think that these experiments are very clearly telling us that consciousness is limitless and the ultimate reality.
