Biomedical researcher Robert Lanza has been on the frontier of cloning and stem cell studies for more than a decade, so he's well-acclimated to controversy. But his book "Biocentrism" is generating controversy on a different plane by arguing that our consciousness plays a central role in creating the cosmos.

"By treating space and time as physical things, science picks a completely wrong starting point for understanding the world," Lanza declares.

Any claim that space and time aren't cold, hard, physical things has to raise an eyebrow. Some of the reactions to Lanza's ideas, first set forth two years ago in an essay for The American Scholar, brand them as "pseudo-scientific philosophical claptrap" or "no better than any religion."

Lanza admits that the reviews haven't all been glowing, particularly among some physicists. "Their response has been much how you'd expect priests to respond to stem cell research," he told me Monday.
