SCIENTIFIC MYSTERIES

WHY ARE 9 OUT OF 10 PEOPLE RIGHT HANDED?

In the 160 years in which “handedness” has been studied we have

learned quite a lot, but we still cannot precisely describe why human

populations are biased toward right-hand use rather than left-hand use.

WHAT CAUSES ROCKS TO SAIL ACROSS

THE DESERT FLOOR?

In several locations around the world, rocks have been shown to

scoot along the desert floor, sometimes turning or reversing

direction with no good reason.

HOW DO BIRDS MIGRATE TO THE SAME AREA EVERY YEAR?

Short of hiding a GPS beneath their wings, the best explanation

thus far has to do with Earth’s magnetic poles.

EVEN CRAZIER, HOW DO MONARCH BUTTERFLIES

KNOW WHERE TO MIGRATE?

Like birds, monarch butterflies take part in an annual migration of

thousands of miles. The only weird thing is that they only live

6 months and no butterfly ever makes the migration twice.

So how do they know where to go?

WHY DO GIRAFFES HAVE SUCH LONG NECKS?

Although there are theories as to the reason, it has long been known

that they do not use them for feeding.

HOW DO CATS PURR?

You’d think someone would just grab a stray cat and take a look right?

Well, apparently it’s more complex than that. With theories

ranging from blood surging through the vena cava to

the laryngeal muscles.

IS LIGHT A WAVE OR A PARTICLE?

The consensus is that light is both…at the same time.

No one is really sure how that works though.

WHAT CAUSES GRAVITY?

This one has stumped scientists perhaps more than any other mystery.

Once again, classical physics and quantum mechanics butt heads.
