Bored by real-life levitation, already? All of a sudden, a bunch of respected physicists are started to claim that time travel may be theoretically possible. For some kinds of particles, maybe.
Heinrich Päs at the University of Alabama believes neutrinos - "those ghostly subatomic particles that flit through the
Earth as easily as raindrops through a spring sky" - might exist partially outside of our three dimensions, and, therefore, could have the ability to travel through time. Fermilab experiments seems to offer what may be partial confirmation.
Meanwhile, Technion-Israel Institute of Technology physicist Amos Ori "has developed a theoretical model of a time machine," according to a press release. The theory calls for a "time loop to form as a donut-shaped vacuum, inside which time would curve back on itself, so that a person traveling around the loop might be able to go further back in time with each lap."
Um, OK. But before you start planning to send our
back to the past to kill Osama's mamma, keep in mind Päs' words, as he introduces his presention, "Travelling back in time: Neutrinos in extra dimensions,"
