http://blog.lib.umn.edu/itcomm/discover/physics/ Hundreds of questions have been submitted to the University of Minnesota's Driven to Discover Web site. Here, faculty and staff from the Institute of Technology answer your "single greatest questions." en Copyright 2007 Fri, 12 Jan 2007 15:49:33 -0600 http://www.sixapart.com/movabletype/?v=3.33.uthink http://blogs.law.harvard.edu/tech/rss Neutrinos are particles with the smallest mass, the weakest interaction, and no electric charge. Neutrinos change as they travel and their oscillations could tell why the universe exists. U of M physicists discovered the third of the three neutrino types and are measuring the oscillations of neutrinos shot through the earth from Chicago to the U of M laboratory in northern Minnesota.

Gravity, he says, is the manifestation of that distortion.

That's because, according to their scientific analysis, the Big Bang was the event that created both space and time. Therefore, there was no "around here" and no "before" until the Big Bang occurred.

But how much would you have to eat -- and would you breathe all of the Earth's oxygen as you ran? Those are some of the questions posed by U of M physics professor, James Kakalios in his popular seminar "The Physics of Superheroes."
