Discussion: Gravity

Big Think presents Erik Verlinde, who is a Dutch theoretical physicist and string theorist. The theoretical physicist believes that gravity is an emergent phenomenon, not the elemental “force” that Newton and Einstein theorized it to be. He thinks it is the result of patterns of complex, microscopic phenomena.

By NASA on the mission of the Gravity Probe:
NASA’s Gravity Probe B (GP-B) spacecraft has confirmed two key predictions derived from Albert Einstein’s general theory of relativity. Launched in 2004, GP-B was designed to test Einstein using four ultra-precise gyroscopes to measure the hypothesized geodetic effect, which is the warping of space and time around a gravitational body, and frame-dragging, which is the amount a spinning object pulls space and time with it as it rotates. (News briefing held May 4, 2011 at NASA Headquarters in Washington.)

By SETI and Barry Muhlfelde who has been at Stanford University for the past 23 years working on the Gravity Probe B Experiment. With an educational background as follows; BS from RPI, MS & PhD from University of Rochester and Post-Doctorate at IST, Boulder, CO.

And lastly a presentation by Big Think and Michio Kaku on the Higgs Particle and its relation to gravity. Dr. Michio Kaku is an American theoretical physicist, the Henry Semat Professor of Theoretical Physics in the City College of New York of City University of New York. Answering the question; What is the Higgs boson? Michio Kaku describes the so-called “God particle” as a fuse. “It’s a match. It’s the spark that set off the Big Bang. It put the bang in the Big Bang.
