Want to learn a thing or two about time travel, teleportation, or simultaneous existence? A fun and easy way to make that happen is to listen to a weekly radio show hosted by Michio Kaku by the name of Explorations.

Dr. Kaku is a theoretical physicist and my all time favorite popularizer of science. Many people out there consider him to be towards the top of the smartest people on the planet list, not just because he looks good on television, but more for his incredible talent of distilling down esoteric concepts to a level that's easy to understand and fun to listen to.

In November of 2007 he reaffirmed his belief on the Coast to Coast radio show that there is a 100 percent probability of extraterrestrial life out there in the universe. It might be the most grounded statement on life beyond our planet, but Michio is quick to point out the vast distances between possible locations and doesn't seem to put much credibility to the hypothesis that other life forms have already visited Earth and may be watching us right now.

Explorations is a great place to stay up to date on the latest developments in science, technology, politics, and the environment. You can actually feel your brain expanding as his words add more understanding to a world view that is becoming more and more complete with each episode.
