The biggest mystery of all is love. Science, explain why! Why does it hurt?

Parallel Universes

Everything you're about to read here seems impossible and insane, beyond science fiction. Yet it's all true.

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 believe that these parallel universes exist less than one millimetre away from us. In fact, our gravity is just a weak signal leaking out of another universe into our.

The 10th Dimension

In string theory, physicists tell us that the subatomic particles that make up our universe are created within ten spatial dimensions (plus an eleventh dimension of "time") by the vibrations of exquisitely small "superstrings". The average person has barely gotten used to the idea of there being four dimensions: how can we possibly imagine the tenth?

Astrophysics taking off on Superman

It is the flying that seems to baffle everyone.

How, exactly, does Superman fly? Or does he, really?

(...)

"The flying always bothered me,'' admits Richard Muller, a professor of astrophysics at Cal and a Superman fan. "I think what he really does is leap and guide himself along the air currents. Or, if you can't really rule out flying, maybe he has a mechanism for somehow forcing air backward -- what if the pores on his skin eject microscopic amounts of excess moisture, like sweat?''

Uh, OK. The real point is that the physicists get it.

Light so Fast it Travels Backward?

In the past few years, scientists have found ways to make light go both faster and slower than its usual speed limit, but now researchers at the University of Rochester have published a paper today in Science on how they've gone one step further: pushing light into reverse. As if to defy common sense, the backward-moving pulse of light travels faster than light.

Confused? You're not alone.
