Sorry Trekkies: Science proves time travel and warp drive not possible

Not long ago, Vanderbilt University physicists planned to use the world’s largest atom smasher, the Large Hadron Collider, to cause matter to travel backwards in time and things were looking up for time travel. Now, Hong Kong University of Science and Technology physicists say they have proved that nothing can travel faster than the speed of light which pretty much puts an end to the dream of time travel as well as faster-than-light warp drive.

“Einstein claimed that the speed of light was the traffic law of the universe or in simple language, nothing can travel faster than light,” the university said on its website.

The possibility of time travel was raised 10 years ago when scientists discovered superluminal – or faster-than-light – propagation of optical pulses in some specific medium reports HeraldSun.com.au. It was later found to be a visual effect, but researchers thought it might still be possible for a single photon to exceed light speed.

“The study, which showed that single photons also obey the speed limit confirms Einstein’s causality – that is, an effect cannot occur before its cause,” the university said.

The team found that, as the fastest part of a single photon, the precursor wave front always travels at the speed of light in vacuum. The main wave packet of the single photon travels no faster than the speed of light in vacuum in any dispersive medium, and can be delayed up to 500 nanoseconds in a slow light medium. Even in a superluminal medium where the group velocity (of an optical pulse peak) is faster than the speed of light in vacuum, the main part of the single photon has no possibility to travel faster than its precursor.

Warp drive, proposed a faster-than-light propulsion system where a spacecraft so-equipped might have traveled at velocities greater than that of light.

In other words, time travel and warp drive are out but Photon Torpedo’s are still possible.

Time lapse video reveals very slow man

Time lapse videos are all of the rage in the travelsphere these days (bonus points if the camera moves at the same time!) so there’s no surprise that the genre has made its way to subjects as bland as intersections.

Youtube user DENJCA29 had his camera trained on the corners of 5th and Spring in Los Angeles when he noticed a strange anomaly. When played at 8 times the normal speed, cars and humans whiz past in streaks of color and light — except for one man. Shown entering the frame from the left in a red shirt, the man slowly drifts across as if floating through time unnoticed, calmly standing with his hands in his pockets and moving inch by inch.

Whether he’s just not in a hurry or he’s actually player in the time lapse game we’re not sure. But the video is a pretty cool product.


Elvis road trip has more stops than Graceland

Themed road trips can take on a whole different meaning than simply loading up the car and heading out on the highway. Choosing to stop along the way at everything from each National Park for a photo by the entrance sign, every major sports venue and coming away with a home-team ball cap or all airports along the way just to watch planes take off can transform a simple drive into a memorable road trip of a lifetime. Whatever your interest, a well-planned and themed road trip can be a lot of fun. Even a tour devoted to Elvis Presley can work.

The Musical Instrument Museum (MIM) in Phoenix, Arizona will be All Shook Up next month with the introduction of an Elvis Presley exhibit in the museum’s newly renovated Artist Gallery on August 6th.

Guests will get to experience The King of Rock ‘n’ Roll through a collection of personal items, clothing, and musical instruments. One highlight of the exhibit will be the priceless 1975 Martin D-28 acoustic guitar that Elvis played during his 1977 tours, including his last concert on June 26 in Indianapolis, Indiana. In addition to displaying it, MIM has been chosen by Elvis Presley Enterprises to restore the guitar to the condition in which Elvis last played it.The new Elvis exhibit, opening August 6, 2011, will also feature a collection of items on loan from Elvis Presley’s Graceland in Memphis, Tennessee and is located at 4725 E. Mayo Boulevard in Phoenix .

Other choices for stops on an Elvis road trip might include a stop by Elvis’ favorite roller coaster, a classic wooden coaster known as the Zippin Pippin in Green Bay, Wisconsin. Earlier this year, Gadling’s Joel Bullock told us:

“It was known to be Elvis Presley’s favorite roller coaster as he often rented out the park so that he could ride it without being bothered by fans. Reports are that Presley rode Zippin Pippin eight days before he died. To support the ride’s history, Bay Beach Amusement Park is working on adding Elvis’ favorite food, peanut butter and banana sandwiches.”

Surely no Elvis road trip would be complete without a stop by Las Vegas to visit the city’s official Elvis, Jesse Garon. Garon sponsored rescued miner Edison Pena in 2010 after the music and movies of the King including the 1960s Elvis movie Viva Las Vegas and Jailhouse Rock were to pass the time and keep up the spirits of all the miners trapped underground. Stick around Vegas for a while too, Cirque du Soleil’s show Viva Elvis at ARIA Resort & Casino is worth the overnight.

Even Branson, Missouri has a Elvis stop to consider with their Elvis and the Superstars show where they throw in Tom Jones and Stevie Wonder (impersonators) for a two hour show that AOLTravel says “you will forget that the people on stage are not the real thing”.

As with any travel, planning is half the fun and a themed road trip is no exception.

I remember a high school road trip I took once: stopping at (what seemed like) every Ford dealership between Kansas City and St Louis for repairs. That wasn’t the original plan, a theme we had thought of in advance or realization of any dream but one we won’t forget any time soon.

Six Driving Tips from a Summer Spent on the American Road


This summer, I’ve driven more than 5,000 miles, from the Great Lakes to New England to Florida and beyond. Operating my car for more than 150 hours in about six weeks doesn’t make me a professional driver, but it certainly has exposed me to heaps of stupidity on America’s highways, interstates and surface roads. With my summer’s experience, I respectfully submit the best six ways you can be a better driver by this evening’s commute.

Keep an open mind: Driving is a lot like Garrison Keillor’s Lake Wobegon: Everyone thinks they’re above average behind the wheel. Sadly, the real world doesn’t work like radio, and statistically half of people are worse than average drivers. As Tom Vanderbilt points out in his phenomenal book Traffic, it’s not really anyone’s fault: psychology, society and plain old habit conspire to make driving one of the most difficult undertakings of our daily lives, even if it seems natural. Admitting that you may not be the world’s best driver paves the way to the second most important thing you can do…

Pay attention: A great number of car crashes could be avoided if drivers were simply paying attention. It’s not easy! Radio, cup holders, cell phones, iPods, kids, pets and navigation gizmos all vie for our attention in the cockpit. But good drivers banish distraction and watch the road–in front of them, beside them and behind them. It takes more mental energy and you’ll feel a little silly constantly checking your surroundings but at least you won’t be reading the newspaper behind the wheel. (I’ve seen it happen.)

Cruise carefully: The thing about cruise control is that it doesn’t actually drive the car for you: It’s up to the operator to actually slow and steer the vehicle. But that’s changing with adaptive cruise control, a feature I have in the Explorer that Ford’s loaned me this summer. (Other carmakers are starting to add the feature, too.) Rather than simply plow ahead at a constant speed, this new cruise system adjusts the throttle and brakes to keep a minimum distance between my vehicle and the one in front of me. Safer, yes, but still not autopilot.

Respect truckers: The idea that truckers are out to crush all four-wheeled cars is as outmoded as tail fins. But pros in big rigs have, by virtue of their size, a harder time accelerating and braking than those of us in passenger cars, meaning it often feels threatening to be around fully loaded trucks. By giving these drivers a wider berth, you’ll make their day and your day a little bit easier–not to mention safer.

Press the pedals: In an attempt to drive more safely, drivers often don’t push their machines anywhere near their mechanical limits. Driving on a race track earlier this summer gave me a better appreciation for my vehicle’s capabilities. Defensive driving or race training courses can help train you to trust your car to do its job at high speeds, under stressful driving conditions–leaving you to think and react rather than scream in terror.

Don’t drink and drive: This advice sounds obvious, but more than 10,000 people were killed in accidents involving alcohol in 2009. Driving drunk is wildly dangerous–and it’s unnecessary. Think a cab ride home at the end of the night is too expensive? How much are court costs, lost employment and possibly much worse? In one case, more than $5,000.

Beatles cruise promoter asks: “What if Paul or Ringo came along?”

Lately, the focus of themed cruises has been on popular musicians like rock star musician and reality TV star Bret Michaels, Taylor Swift and Kid Rock among others. Themed cruises appeal to groups of people varying from broad interests like “motorcycles” and “rock music” in general to smaller, more specific interests like Harley-Davidson motorcycles or a specific band like KISS. Gaining in popularity, promoters book huge blocks of cabins on existing sailings or charter entire ships to meet the demand and cruise lines are paying attention.

Beatles Tribute Cruise (BTC) 2012
is on sale now and filling up fast. That’s prompting offers from other cruise lines looking to woo the annual event away from Royal Caribbean and a call to invite one of the remaining Beatles along for the ride.

“It’s a bold move….what’s happened is that the cruise’s popularity has initiated some amazing–and I mean AMAZING—offers from other cruise lines to “jump ship” and sign on with them, and they are asking if we could get Ringo or Paul to join us!” BTC promoter Woody Lifton told Examiner.com.

What would cruise lines offer to get the Beatles cruise and Paul McCartney or Ringo Starr on board?”Basically anything they wanted, I suspect” said Lifton adding “With a private ship and (the) high quality cruisers we get on BTC, they would have a really nice time with the ability to interact with fans to the extent they wanted, in a safe atmosphere with whatever security they would need.”

An annual event, the 2011 Beatles cruise was a fundraiser for Thrive/Survive Los Angeles to support young adult cancer survivors. On-board, a raffle was held with close to 100 Beatles-related item given away during the sailing. Beatles Cruise 2012 sails from Ft Lauderdale on 2/4/12 aboard Royal Caribbean’s Oasis of the Seas and set to coincide with the 48th Anniversary of The Beatles first U.S. Television appearance on the Ed Sullivan Show in 1964.

Will Beatles Tribute Cruise 2013 or 2014 be able to land the biggest fish of all, Paul McCartney or Ringo Starr?

“Yes we feel we could make this happen” concluded Lifton “and as with all of our past cruises I’m sure we’ll exceed everyone’s expectations”
