"The moving finger writes and having writ moves on, nor all your piety can lure it back nor your tears wash out a word of it." Jon Donne.
If Prof. Ron Mallett has his way, the words of Jon Donne will be a quaint aphorism that people used to say. The reason Mallett says this is because he believes that the time barrier can be broken and that -- someday -- people will have the technology to travel into the past.
Almost immediately on announcing his speculations, Mallett became the topic of intense media interest including a Learning Channel special and great media coverage. And this is rightly so because the back story of Mallett's motivation -- so ably told in this book -- is itself so compelling.
In 1955, while still a child, Ron Mallett lost his father who died of heart failure at the age of 33. Loving his Dad as intensely as he did, Mallett began to dream of breaking the time barrier to rejoin his father just to tell him "I love you."
Just as everyone can easily connect with Mallett's motivation, mostly everyone will find themselves somewhat befuddled by the science behind Mallett's speculations. This isn't because he doesn't do a good job of explaining himself, but rather simply because scientific explanations typically tend to tax comprehension.
That being said, his theory is an ingenious one: that just as gravity can used to distort time, so can concentrated light. In this way, Mallett must now consider it the sweetest serendipity that he worked in the private sector with lasers for a formative part of his early career. In this way, he became immediately acquianted with the very device he intends to employ in his time travel device.
The typical time travel scenerios that have been set out involve a radical twisting of space. If we were bugs living on a sheet of Christmas wrapping paper, our travel from one end of the sheet to the other would be greatly speeded if we could somehow get the paper from the ends to connect with each other. And indeed, this is what the tradition theories of time travel all propose: that somehow -- whether it's through cosmic strings as speculated by J Richard Gott or black holes as speculated by Kip Thorne -- a force so great is created that space is litterally forced to warp back on itself.
Unfortunately, at the end of the day, Mallett's theories will probably face the same fate at those of Gott and Thorne respecting time travel by people into the past...failure. However, having opened by quoting Donne, it's perhaps best to close by quoting Theodore Roosevelt who said:
"Pity not those who have failed but those who live in that grey twilight that knows neither success nor failure."
By dint of genius, Mallett -- ultimately successful or not -- has irrevocably taken himself out of that "grey twilight" and us with him...if only in our hearts and imaginations.
