Brian Greene's excellent series examining string theory and modern physics.

There is a world where nothing is what it seams. A world so small that you can't even see it. The world inside the Atom. To see the atoms in a basketball you would have to blow it up to the size of the world. Then the atom would be the size of a grape. To see inside the atom then blow it up to the size of Saint Peter's in Rome (14 stories ...

Michio Kaku explores temporal concepts in regard to the human animal.

Michio Kaku explores temporal concepts in regard to the planet.

Particle physicist Dr. Brian Cox believes that the answer to the meaning of the universe lies in gravity. On a road trip across the USA, Brian fires lasers at the moon in Texas and goes wild in the desert in Arizona. He encounters the bending of space and time at a maximum security military base and tries to detect ripples in our reality in ...

This documentary, featuring Michio Kaku and numerous physicists and nuclear experts, examines the devastating what-if scenario, as well as the all-too-real history of public exposure to radiation - the silent, invisible and odorless killer - from x-ray exams, to Hiroshima, and to the recent accidents at Three Mile Island and Chernobyl. While ...

The universe began with a massive expansion, billions and billions of years ago, and it continues to expand with every passing second. The idea that the universe, and man's very existence, began with a ''Big Bang'' is no longer a topic of debate among most scientists--it is essentially taken as fact. How has man come to this ...

Wielding laypeople's terms and a sense of humor, Nobel Prize winner Murray Gell-Mann drops some knowledge about particle physics, asking questions like, Are elegant equations more likely to be right than inelegant ones? Can the fundamental law, the so-called ''theory of everything,'' really explain everything? His answers will surprise you.

Scientists now believe there may really be a parallel universe - in fact, there may be an infinite number of parallel universes, and we just happen to live in one of them. These other universes contain space, time and strange forms of exotic matter. Some of them may even contain you, in a slightly different form. Astonishingly, scientists ...
