Michio Kaku: The Universe in a Nutshell

Michiko Kaku is like the Asian version of Einstein, he has become famous after writing several best selling books on theoretical physics. He has demonstrated his genius from early age by creating a homemade particle accelerator in his backyard for his third grade science fair. His major achievement are his discoveries in string theory where he describes the universe as music, and the string’s elemental particles as musical notes.
On this 40 minute video Kaku simplifies the universe in its most comprehensive and simple manner from the Big Bang to string theory and the future of mankind.

Stephen Hawking’s Ted Talk

Stephen Hawking was invited to this Ted talk to answer some questions about the universe.  How did the universe begin? How did life begin? Are we alone? — and discusses how we might go about answering them.

On his wheelchair and his voice synthesiser patiently delivered his 10 minute speech and answered a question from the audience.

Time Travel Explained by Michio Kaku

One of the greatest enigmas of modern science is the possibility of time travel.  Einstein proved through the general theory of relativity time travel into the future.  However, time travel into the past is much more complex to understand in modern physics.

Michio Kaku explains in this video a theoritical model where the fabric of space time can be manipulated to travel into the past.  This model impossible to build today with our current technology might be a reality in the distant future, making possible time travel possible in a commercial scale.
