Dr. Michio Kaku discusses the future. The first video is a wider view of the futer, the second is about the super car. This is a car that I have been wanting for a super car for years but it is getting closer all the time.
Michio Kaku is great at explaining physics in an interesting way. If you're interested in Science Fiction then he's a great source for learning about some of the things that scientists are looking at.
Michio discusses Type 1, Type 2 and Type 3 civilizations
Michio discusses time travel
Aging and the fountain of youth
The first part of this covers the same subjects as the first but the second half is quite interesting.
