A Void In The Heart Of The Great Pyramid

The oblong cavern, above the Grand Gallery (a long inclined passageway that leads to the King’s Chamber.)

There’s a hidden “void” inside the Great Pyramid of Giza, “a space 100 feet long, similar to the Statue of Liberty from her heel to her head.”

A team of researchers got a picture of what’s deep inside the stone structure, employing a technique from the field of particle physics. Standing in the Queen’s chamber, they sent a beam of muons—heavier siblings of electrons that can penetrate rocks.

As the muons pass through matter, they lose energy and decay. So, if they detected a small quantity of muons, it’d mean they were passing through matter. But if they detected a lot of muons, it’d suggest they were traveling through empty space or less dense material.

When they analyzed their data, they found an unexpected excess of muons. They don’t know if it’s a chamber, a tunnel, or an enormous gallery, but its steep incline makes it unlikely that it was room of some sort.

Hop On And Fly Away … In A Taxi

Like the flying saucer-shaped car, envisioned in the Fifties, commuters in Dubai will soon be able to hop aboard flying taxis and “soar over busy streets and past the desert city’s gleaming skyscrapers, all—quite literally—at the push of a button.”

The eight-rotor passenger drone, capable of carrying a single, 220-pound rider and a piece of small luggage, can fly up to about 30 miles or about 30 minutes, on a single battery charge. It has a top speed of 100 m.p.h., but it’d, typically, operate at 62 m.p.h.
