The real life Doctor Who who believes he can build a time machine
The Daily Mail ^ | 27th July 2007 | MICHAEL HANLON

Suppose it were possible to go back in time and meet the dead. To say all the things you never got a chance to tell a loved one who died before there was a chance to make your peace.

Just think if you could go back and warn someone that their lifestyle, their smoking or heavy drinking was driving them into an early grave.

You would not only be able to meet the dead - but to save them as well.

A new book tells the story of an extraordinary man whose life work is inspired by a longing to do just that.

It was the devastating sudden death of Ronald Mallett's beloved father which sparked his obsession with time-travel.

In pursuit of his seemingly impossible goal, he has overcome poverty and prejudice to become one of only a handful of top-flight black physicists in the United States.

He has enjoyed a glittering career as a professor at one of the country's leading universities - an achievement in itself.

But there has been only one motivation: to build a time machine. And, after years of painstaking research, Mallett is sure he's cracked it.

His journey began in the early 1950s, when this intelligent and inquisitive boy was ten years old.

He lived with his parents Boyd and Dorothy in a working-class Jewish area of the Bronx, in New York city. The Malletts were happy there, having escaped the terrible racism of the Deep South.

Boyd Mallett was a gadget freak, and a talented, respected electronic technician - one of his jobs was to wire up the new United Nations building being constructed in Manhattan.

His son worshipped him, and the pair would spend many hours in the evenings experimenting with capacitors and circuits, building crystal radios and other gadgets.

Then, the night after his parents' 11th wedding anniversary, Boyd died suddenly of a heart attack.

"For me, the sun rose and set on him," Ron Mallett said later. "It completely devastated me."

Boyd Mallett's death was probably preventable. He had always been a heavy smoker and workaholic and had started drinking too much.

His son sank into a despair that would not lift; indeed, he became severely depressed. Ronald simply could not accept that he would never see his father again. And he began to wonder if there was a way they could be reunited.

Mallett devoured the pulp sci-fi comics of the time, and began to realise that time travel was, at least in fiction, a possibility. Then he read what is one of the finest science-fiction stories ever written, HG Wells's The Time Machine.

In the novel, the time-travelling hero explains: "Scientific people know very well that time is only a kind of space. We can move forward and backward in time, just as we can move forward and backward in space."

Mallett was dumbfounded. If he could build a time machine, he could go back and change history and prevent his father's death.

From that day, Mallet became obsessed with time travel, despite having no clear idea of how it could be accomplished.

Wells's book was, of course, entirely fictional, and yet, just a few years after it was written, a German-Jewish physicist called Albert Einstein blew the science community apart. Einstein showed that time and space were indeed different aspects of the same thing - a concept called spacetime - which is at the heart of how physicists understand the way the universe is.

Mallett became obsessed with the German scientist - who had died in 1955, the same year as his father. Most importantly, Mallett realised - as Einstein had himself - that the new way of thinking about gravity, space and time contained in the physicist's Special and General theories of relativity meant that a time machine was at least possible in theory.

Einstein's equations showed that by twisting spacetime around, it is possible in theory to make a connection from future to past. Step into this timeloop, and you could emerge years later or earlier.

This idea would form the basis of Mallett's putative time machine. But, back in 1950s New York, he was a long way from his goal. Growing up poor and black, one of four children raised by a widowed mother who made ends meet by window-cleaning, is not an ideal recipe for academic success.

Undaunted, he studied hard at school and achieved good grades, particularly in the sciences. However, a university education was out of the question - there was simply no way his family could afford to pay for it.

So Ron Mallett joined the U.S. Air Force, in the hope of being granted a military scholarship so that he could later study physics. His test grades were so good that he was fast-tracked into the USAF's electronics school.

Despite his success, the past still intruded in the most horrible ways. Mallett's first tour of duty was in Biloxi, in the Deep South. There, for the first time in his life, he encountered the soul-destroying racism that had driven his grandparents north 40 years before.

"The first thing I noticed," he writes, "were the signs, the likes of which I had never seen before. 'Whites only'. 'No Colored'."

There was talk of beatings and worse for black servicemen who strayed off base. Mallett made a vow to remain on base for the entire duration of his training, which included courses in electronics and computing. He also spent hours in the well-equipped library, devouring everything he could both by and about Einstein.

His studies paid off. After he was discharged, he won a place at Pennsylvania State University, and began a degree in physics.

Eventually, in 1973, he won his doctorate, only the 79th black American ever to do so in this subject. Part of his thesis was an investigation into the theoretical possibility of using gravity to reverse the passage of time. In 1975, he was awarded a job as a professor of physics at Connecticut University - where he has worked ever since.

He remains the only black physics professor in America.

Despite the respectability of his CV, he still felt he couldn't discuss his ideas openly. "I feared professional suicide," he says now.

But, as his work continued, the story got out. Mallett's time machine went public in 2001, when New Scientist magazine ran an article about his design, and TV appearances followed.

"Mallett isn't mad," the New Scientist article said. "None of the known laws of physics forbids time-travel.

"In theory, shunting matter back and forth through time shouldn't be that difficult."

So, how do you build a machine which will take you back into the past - or forward to the future?

In fact, there have been several plans for a time machine devised by physicists since Einstein's mind-blowing discovery that reverse timetravel should be possible.

In 1974, Frank Tipler, a physicist at Tulane University in New Orleans, calculated that by constructing a huge cylinder in space and setting it spinning, it would be possible to drag spacetime into loops, creating lots of backwards time portals into which you could leap and then emerge in the past.

But he calculated that the cylinder would have to weigh about as much as the sun, and be compressed into a tube 60 miles long and 40 miles across.

Alternatively, as physicist Kip Thorn proposed in the 1980s, you simply need to create a 'wormhole' - a tear in the fabric of spacetime, using perhaps a tame black hole or dozens of nuclear bombs.

These ideas, while scientifically correct, were hardly practical. Squashing the sun into something the size of Dorset is likely to be beyond our ken for some time, and harnessing the power of a black hole sounds even harder.

Mallett's solution is much simpler. He thinks he can reverse time by using just a circulating beam of light. Light is energy, and energy can cause spacetime to warp and bend, just like gigantic spinning cylinders, he explains.

In 2000, he published a paper showing how a circulating beam of laser light could create a vortex in spacetime. It was, he says, his eureka moment.

The details are complex, to say the least. But, in essence, Mallett believes it is possible to use a series of four circulating laser light beams swirling spacetime around like "a spoon stirring milk into coffee".

If you were to walk into this 'timetunnel' - which would resemble a large vortex of light a few feet across - you could emerge at some point in the past. He thinks he can build a prototype machine in the lab, using today's technology, with funds of just $250,000 (£120,000).

However, Prof Mallett is fussy about who gives him the money. "We want non-military sources. I don't want to get to a certain point and get 'top secret' slapped over the project and have it taken away from us."

There are several important things to realise about Mallett's time machine. For a start, it would only be possible to travel back in time to a point after the machine was first switched on.

If you turned on the machine, on January 1 say, and left it running for three months, you could enter the machine in March and only travel back as far as January 1.

So no trips back to the Middle Ages or to Ancient Rome.

This would be staggering enough. Just think: a time-traveller could go back and meet himself. Or he could send back information into the past - including the results of horse races, stock market movements.

But consider, too, all the weird paradoxes that the time machine would create. You could come face-to-face with your past self, causing untold confusion. What, for example, would happen if you killed your past self? Would both versions of 'you' die at the same time?

Mallet believes these paradoxes would not in themselves prevent the construction of such a machine. But there are plenty of sceptics.

Some physicists think that the laser upon which his machine depends would need to be impossibly large or powerful. Others point to Stephen Hawking's 'chronology protection conjecture', which says that quantum effects may conspire to prevent the possibility of a time machine.

But, while some physicists have questioned Mallett's approach, no one has yet proved with absolute certainty that the machine would not work.

Mallett is now 62 years old. He still believes he will live to see the creation of the first time machine.

Sadly, the way it works means that he will never be able to fulfil his original wish - to warn his father about his deteriorating health. "My solace is that if this works, future generations will be able to use this technology to prevent the tragedy that I went through," he says.

If he is right, the little boy from the Bronx who lost his beloved father all those years ago will end up being the most famous inventor in history.

Something is warped and it isn’t time.

I’ve never understood the principles of time travel but it seems that if he were to succeed and go back in time and prevent his dad’s death, wouldn’t that also change his motivation to build the time machine in the first place? Like it never would have been built had his dad not died? How does that work? Or does he just get to create some parallel universe?

I know this shows my age, but it reminds me of the TV series from the ‘60s, Twilight Zone.

I hope this guy is successful, cause the first thing I’m going to do is go back to 1970, and change the way I responded to that boy with the (then) classic Ford Fairlane (black, white top, with red leather interior), the one who broke my heart (grin).

Yeah, maybe like Nikola Tesla.

Tesla was the greatest inventor of all time, yet hardly anyone knows who he was.

I read a short article about an interesting time travel theory. A physicist had figured out a way to make time travel permissible without breaking any physical laws; however, the same equations also showed that any event you went back to observe would have a probability of one. In other words, there wouldn’t be a 50:50 chance of a particular toss of a coin coming up heads. If it came up heads before, it will come up heads every time you go back to relive the event. Conversely, the odds of something happening that didn’t happen before would be zero. A car crash that didn’t happen won’t happen when you go back to see that period again. (Of course, on a quantum level, this means that you wouldn’t see anything anyway. Since the photons necessary to form the image did not impact upon your retina the first time around, the odds of them doing so again on a replay of the event would be zero.)

I picture this guy with a basement full of old toasters that somehow figure into his plan.

LOL!

Perhaps, but 200 years ago, no one was particularly serious when they spoke or wrote about 'flying' to the moon.

Well, people can laugh, but I’m sure many of the famous inventors were thought of as kooks. I think one day someone will figure out time travel, if our planet survives long enough.

So many alternate realities that nobody’s enjoying. We really do need time machines so we can experience the unexperienced, the might-have-been.
However...you know how you play solitaire on the computer and it has an option to restart the game? If you lose, do you opt to restart the game and try again with that exact same layout? Nah.
If I had the choice to live my life (and maybe botch up a little differently), or start a whole new one, you wouldn’t see me grabbing the keys to the time machine.
Besides, I like where I am now, and my mistakes got me here, just as surely as my efforts did.

Well, here's how it works. His drunk dad tells him to get the "F" lost and downs another three belts of booze before falling asleep with a lit cigarette in his hand, thereby saving his preciious time machine.

If he's particulary unlucky dear old dad pulls a gun and his time saga ends on the first trip. Just as well, imagine the tediousness of dragging dad's drunk rear to countless AA meetings, just to learn the lesson Bill Murray went through with the old codger in Groundhog Day?

I think, you said think, not know, that the author of this piece has no interest in giving a single soul peace; if anything he is hell-bent on harrassing the less-perfect until eternity.

What better insight to his “reasoning” than this statement near the top where he says:

“Just think if you could go back and warn someone that their lifestyle, their smoking or heavy drinking was driving them into an early grave.”

Usually we say something meaningless and stupid when somebody dies, like, “Don’t he look nice,” but this guy will be standing there with a club ready to beat you back to life just so he can beat you into submission again.

When will we be rid of these fools?

That is incredibly cheap. You would think that some billionaire would finance this project just on a lark.

However, Prof Mallett is fussy about who gives him the money. "We want non-military sources. I don't want to get to a certain point and get 'top secret' slapped over the project and have it taken away from us."

I don’t think using private money is going to prevent the DOD from taking this project away from him if they think he will be successful. On the other hand it may be the DOD that has prevented him from getting a private backer so far.
