Mad, Mad, Mad, Mad Scientist: Lisa Randall

While doing research for an upcoming article on string theory (a "big idea" if we ever saw one), I ran across this interview with Lisa Randall. It contains the following wonderfully wacky three questions, in which Randall applies her brain to "branes," higher dimensions, and alternate universes. Gotta love physics:

If there are more than three dimensions out there, how does that change our picture of the universe?
What I'm studying is branes, membranelike objects in higher-dimensional space. Particles could be stuck to a three-dimensional brane, sort of like things could be stuck to the two-dimensional surface of a shower curtain in our three-dimensional space. Maybe electromagnetism spreads out only over three dimensions because it's trapped on a three-dimensional brane. It could be that everything we know is stuck on a brane, except for gravity.

Yet we very clearly see only three dimensions when we look around. Where could the other dimensions be hiding?
The old answer was that the extra dimensions were tiny: If something is sufficiently small, you just don't experience it. That's the way things stood until the 1990s, when Raman Sundrum and I realized you could have an infinite extra dimension if space-time is warped. Then with Andreas Karch, I found something even more dramatic—that we could live in a pocket of three dimensions in a higher-dimensional universe. It could be that where we are it looks as if there's only three dimensions in space, but elsewhere it looks like there's four or even more dimensions in space.

And there could be a whole other universe set up that way?
Possibly. It would be a different universe because, for example, bound orbits [like Earth's path around the sun] work only in three dimensions of space. And the other universe could have different laws of physics. For example, they could have a completely different force that we are immune to. We don't experience that force, and they don't experience, say, electromagnetism. So it could be that we're made of quarks and electrons, while they're made up of totally different stuff. It could be a completely different chemistry, different forces—except for gravity, which we believe would be shared.

Finally, for those of you who think that theoretical physicists are all nerdy old men wearing pocket protectors: check out Randall's picture after the jump, which could inspire a person who make all kinds of jokes about gravity and attraction.

The Real Bay of Pigs: Big Major Cay in the Bahamas

When most people visit the Bahamas, they’re thinking about a vacation filled with sun, sand, and swimming—not swine. But you can get all four of those things if you visit Big Major Cay.

Big Major Cay, also now known as “Pig Island” for obvious reasons, is part of the Exuma Cays in the Bahamas. Exuma includes private islands owned by Johnny Depp, Tyler Perry, Faith Hill and Tim McGraw, and David Copperfield. Despite all of the local star power, the real attraction seems to be the family of feral pigs that has established Big Major Cay as their own. It’s hard to say how many are there—some reports say it’s a family of eight, while others say the numbers are up to 40. However big the band of roaming pigs is, none of them are shy: Their chief means of survival seems to be to swim right up to boats and beg for food, which the charmed tourists are happy to provide (although there are guidelines about the best way of feeding the pigs).

No one knows exactly how the pigs got there, but there are plenty of theories. Among them: 1) A nearby resort purposely released them more than a decade ago, hoping to attract tourists. 2) Sailors dropped them off on the island, intending to dine on pork once they were able to dock for a longer of period of time. For one reason or another, the sailors never returned. 3) They’re descendants of domesticated pigs from a nearby island. When residents complained about the original domesticated pigs, their owners solved the problem by dropping them off at Big Major Cay, which was uninhabited. 4) The pigs survived a shipwreck. The ship’s passengers did not.

The purposeful tourist trap theory is probably the least likely—VICE reports that the James Bond movie Thunderball was shot on a neighboring island in the 1960s, and the swimming swine were there then.

Though multiple articles reference how “adorable” the pigs are, don’t be fooled. One captain warns, “They’ll eat anything and everything—including fingers.”

Here they are in action in a video from National Geographic:

The House From The Money Pit Is For Sale

Looking for star-studded new digs? For a cool $5.9 million, Top10RealEstateDeals.com reports, you can own the Long Island country home featured in the 1986 comedy The Money Pit—no renovations required.

For the uninitiated, the film features Tom Hanks and Shelley Long as hapless first-time homeowners who purchase a rundown mansion for cheap. The savings they score end up being paltry compared to the debt they incur while trying to fix up the house.

The Money Pit featured exterior shots of "Northway," an eight-bedroom estate located in the village of Lattingtown in Nassau County, New York. Luckily for potential buyers, its insides are far nicer than the fictional ones portrayed in the movie, thanks in part to extensive renovations performed by the property’s current owners.

Amenities include a giant master suite with a French-style dressing room, eight fireplaces, a "wine wall," and a heated outdoor saltwater pool. Check out some photos below, or view the entire listing here.
