Ahead Of It’s Time

One should read The New Time Travelers only if they elevate their thinking. If they are somewhat technically short-gifted, forget it. If they’ve never considered the possibility of actual time travel, this is not their kind of book. If they’ve never opened their mind realizing just how big this universe is, this is not their cup of tea. If they don’t think there’s a God, or if they can’t conceive of any dimensions in this world beyond three, this book is well beyond their comprehension.

But if your mind is allowed to escape the confines of our known universe, you may decide to read on. The book is about time machines, but relate directly to universal laws.

English Major Toomey, Breaches Science Fiction

Author David Toomey, literally makes this book the place where science-fiction blends into reality. Toomey received a PhD in English Literature, and graduated from the University of Virginia (1988). How he understands items described in this book—such as an Event Horizon, Alcubierre Warp Drive, Cauchy Horizon, Copenhagen Interpretation, black-hole, “frame-dragging”, “grandfather paradox”, hyperspace, negative energy, neutron star, quantum foam, “supraluminary”, time dilation, string theory, singularity, wave-particle duality, etc., etc…—cannot be known.

Toomey begins with how a “wormhole”—a hypothetical shortcut through space—was discovered by Ludwig Flamm to solve Einstein’s field equations (1916). It was studied by Einstein again in the 1930s. As H.G.Wells [author original “The Time Machine” (1890)] puts it, “Education becomes more an more a race between education and catastrophe”.

Understanding The Fourth Dimension

Sixteen-hundred years ago, St. Augustine produced a reasonable description of the difficulties in understanding time. “I know well enough what it is, provided that nobody asks me, but if I am asked what it is and try to explain, I am baffled.”

He explains ‘future-ward’ time travel—which has been proven to exist—occurs when a body increases its velocity, and will experience time dilation. The accelerated body’s clock will tick slower than the clock of the universe outside.  Travel to the star Arcturus (36 light-years from earth) and back at near light-speed, will reduce the trip time ten years for the traveler.

It turns out many of Einstein’s ideas came to fruition, including the fact time slows in the vicinity of gravitational fields, and slows greatly in the vicinity of intense gravitational fields. Black holes are so massive, and their gravity so great, light itself cannot escape. Hence, “black” (as in black-holes) with no escaping light.

Backward Time Travel

“Backward” time travel, is also considered possible, after close examination of Einstein’s theories in the 1920s and the late 1970s. The dictum “Absence of evidence is not evidence of absence” propelled many scientists to forge ahead on backward travel.

Most cosmologists are convinced a collapse of the universe is not likely, and the rate of expansion is accelerating.

Where’s Other Time Travelers?

Toomey suggests one of the reasons why we haven’t seen any time machines from the future, is their civilization did not survive long enough to develop time travel. More candidly (and directly hinting God must exist ), he says if one imagines the universe starting over with even one of the values adjusted up or down a fraction, “life” could not have appeared. Had the interaction between neutrons been slightly weaker, we would have a universe in which chemistry, and hence biology, would have been impossible.

Had the force of gravity, or electromagnetism, or even one of the many other constants adjusted up or down even slightly, the universe simply would not exist. He says our existence is either a miracle, or a fluke.

Carbon Most Delicate

The basis of all terrestrial life—the carbon atom—fought against all odds. If the resonance level was only 4% lower, carbon atoms could not form, and life would not exist. In the 1970s, cosmologist Fred Hoyle had an intellectual crisis. While researching resonance states of carbon atoms, his atheism was “shaken” by this discovery. Per Hoyle: “A commonsense interpretation of the facts suggest that a super-intellect has ‘monkeyed’ with the physics, as well as with chemistry and biology, and that there are no blind forces worth speaking about in nature.”

The odds against all the constants having vales conducive to life are higher than astronomical. Lee Smolin (Penn State physicist) estimates chances of randomly chosen constants in elementary cosmological particles leading to a carbon chemistry necessary for life are 1 in 10 to the two-hundred and twentieth power. [Smolen; Three Roads; p. 202] 

Toomey says in the late 1980s physicists have found general relativity allows for ‘past-ward’ time travel through an effect called ‘frame dragging’. They have learned the effect must employ the unphysical—or, impossible, in the universe we know. It took Toomey the last few pages of the book, to reveal ‘learned ignorance’ is inextricable with knowledge. That is, the more we learn, the more we learn how much we do not know.
