Where do missing socks go? Would you believe they drop into a mini-black hole?
|
Now let us consider cosmic mysteries of a completely different sort ... for instance, why do socks disappear in the laundry?
Many hypotheses have been put forward: The eminent thinker Jerry Seinfeld once proposed that socks carefully plan their escape. Another researcher invokes quantum mechanics. Some crackpots even suggest looking under your washer's agitator or in your closet. Can you believe that?
Last weekend, an eminent panel of theorists (including myself) gathered to reflect upon "cannibalistic socks" and other riddles at the SpoCon science-fiction and fantasy convention in Spokane, Wash. I think we may have made as much headway as the Solvay Conference did back in Einstein's day. Here's the rundown on our results:

Even the highest-resolution camera in orbit around the moon can't make out the mark left behind by Neil Armstrong's "one small step" 40 years ago - but NASA's giant leap left a huge mark on men and women around the globe. For proof, all you have to do is page through the more than 1,400 messages answering the question posed 10 days ago: "Where were you when Apollo flew?"

On July 20, 1969, I was an Iowa farmboy watching every black-and-white move of a fuzzy-looking, spacesuited figure on our living-room television set. Astrophysicist Neil deGrasse Tyson was doing pretty much the same thing in New York City (though he was a mere 10 years old, four whole years younger than I was).
Sen. John McCain was sitting in a Hanoi prison - and wouldn't even find out that someone landed on the moon until a year and a half later. But for myriad millions of people around the world, even for McCain's Vietnamese captors, the Apollo 11 landing and that "one small step" on another world was a red-letter day that would be remembered through the decades.
Now it's your turn to share some moonshot memories: Where were you when Apollo 11 flew? Even if you're took young to have been around when the first moon landing took place (which is the case for more than half of the U.S. population), you can still feel free to comment on the past, present and future of space exploration.

Where can you find Stephen Colbert, President Obama, Cleopatra and Leonardo da Vinci all in one place? The Technology & Science section here at msnbc.com, of course. All these celebrities, past and present, were in the news over the past week.
The big question is, why were they in the news? Let's make that 10 big questions. Today, we're rolling out the celebrity edition of msnbc.com's Science and Space Quiz - or the Sci-Q test for short.

When gasoline prices crossed the $4-a-gallon milestone, that got a lot of people thinking about ways to reduce transportation costs. Many are taking a second look at pedal power and mass transit. Others are looking at energy technologies that offer alternatives to fossil fuels. Longtime Cosmic Log correspondent Christopher Eldridge takes a totally different view: Instead of figuring out cheaper ways to travel, how about figuring out cheaper ways not to travel?

In the wake of the X Prize Cup, one reader wrote in to ask why anyone would pay $200,000 for a quick space trip on a rocket plane. "I assume it means much quicker travel time coast to coast, but your story never mentioned anything about why this is the next step in aviation evolution," said Cutter Garcia of Los Angeles.
Point-to-point travel is definitely on the minds of spaceship developers - but before they get to that point, all they can offer are up-and-down sightseeing trips. At least at first, rocketeers will be banking on a luxury market ... the kind of people who are willing to pay $95,000 to go on a North Pole expedition, or buy a cell phone for $20,000. So who better to design the interior of the spaceship than Frank Nuovo, the man behind that $20,000 cell phone?

Some astronomers would be delighted if a super-bright supernova blast like the one reported this week were to occur in our own galaxy. One says it could be "the best star-show in the history of modern civilization." But if the blast was pointed right at us from close quarters? Well, that would be bad.
How so? And how bad? For the answers to those questions, you can turn to some cool Web sites, a few good books ... and a couple of bad movies.

As physicist Stephen Hawking tours America in advance of his April 26 date with weightlessness, he’s clearly hyped up about the trip, says Zero Gravity Corp. founder Peter Diamandis, who saw the great man up close and personal at the California Institute of Technology last week. "He is so excited about the flight,” Diamandis told me. “It was wonderful to see him smile."

There are plenty of ways to become a virtual traveler in outer space. Second Life may be the simulation flavor of the week, and NASA may be carving out its own space there, but there’s a long history of virtual worlds that give you the feel of the final frontier.

Sometimes all you have to do is point to a couple of items, then stand back and wait for the messages to roll in. I'm hoping that will be the case with these items.

We're running
this Associated Press story about the worries that NASA officials and members of Congress have about the "spaceflight gap" - the period between 2010 and 2015 when the space shuttle fleet is retired and the next-generation Orion spaceship is not yet ready for launch. The worry is that NASA might have to rely on (gasp!) the private sector or other countries to provide space services. To be sure, the United States should have its own spacefaring capability, but I'm betting that some people might say the best thing for NASA to do is to
leave the spaceship-building business to the private sector. Others might say that the government has to take the leading role in such a risky business. What do you say?

I was struck by this
comment from John in Kansas: "I want to thank you for the occasional postings of amateur astronomy tools - if you could do more of that, I might be more prepared for next year, when I take my kids out to rural Kansas for the first time to look at the moon, planets and stars. So if an astronomy expert has some sound advice on the best (affordable ... which is subjective, I know) available tools and gadgets for seeing craters on the moon, keep 'em coming!" Now if that's not an invitation for feedback, I don't know what is. Do you have any suggestions for John? Leave them below - and if I think of anything, I'll do the same.
