So someday in the near future hopefully rather than having a foot or a leg amputated we'll just give you an injection of the cells and restore the blood flow. We've also created entire tubes of red blood cells from scratch in the laboratory. So there are a lot of exciting things in the pipeline.

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.

We don't have time to wait for President Bush to change his mind. How many breakthroughs have been missed as a result of this policy?

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.

Sometime in the future, science will be able to create realities that we can't even begin to imagine. As we evolve, we'll be able to construct other information systems that correspond to other realities, universes based on logic completely different from ours and not based on space and time.

Without consciousness, space and time are nothing.

Religion and science look at reality differently.
