Dark matter makes up more than 80 percent of the matter in the universe. But up until now, it’s eluded scientists. Yesterday, however, NASA announced a possible breakthrough. A particle detector mounted on the International Space Station may have detected dark matter. Theoretical physicist Michio Kaku explains.

Dr. Joseph Lykken of the Fermi National Accelerator Laboratory posits that "vacuum instability," that a universe will blow up like a bubble in our universe and sweep across it, consuming everything in its wake. It's pretty serious stuff, but the notion still relies on some far out cosmological theories.

It was announced this morning that this year’s winners of the Nobel Prize in Physics are Serge Haroche and David Wineland "for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems."

A look back at Sally Ride: Her legacy, first space mission, and her work to bring science to the youth of America.

On Wednesday, scientists from the CERN lab in Switzerland will announce the latest evidence about the existence of Higgs Boson particle, otherwise known as the "God particle." Dr. Michio Kaku discusses the basics of the Higgs Boson particle and what makes Wednesday's announcement so significant.

And according to our partner the BBC, the contract for a project called "Solar Orbiter" is set to be signed today. A project of the European Space Agency, the Solar Orbiter will get closer to the sun than any satellite up until now. Dr. Michio Kaku knows a lot about outer space and about future possibilities. A theoretical physicist, he’s the author of the New York Times bestseller "Physics of the Future." He’s here to walk us through what we might learn from this new space project.

2010 may be coming to an end, but a whole new year of news and culture awaits in 2011. All week long, we'll be talking with big thinkers about what they’re anticipating …from new movies to world events. Today, our subject is science, and our guest is the one and only Dr. Michio Kaku, theoretical physicist, bestselling author, professor at the City University of New York, and host of “Science of the Impossible.”

Today, the widely anticipated John Cusack/Rob Corddry vehicle, "Hot Tub Time Machine" hits theatres nationwide. As the title suggests, the film centers on a hot tub that transports its characters through time, back to the more innocent year of 1986.

Rafer Guzman, Takeaway movie contributor and Newsday writer talks about the most memorable time travel movies, and why audiences find these tales so compelling.
