Book Review: ‘The Dent in the Universe’ by E. W. Doc Parris

Last year I published a review of a book entitled ‘Recursion’ by author Blake Crouch. In that review I praised ‘Recursion’ for having a very unusual slant on the old SF theme of time travel. Like ‘Recursion’, the plot of  ‘The Dent in the Universe’ by author E. W. Doc Parris also concerns a very different, and interesting kind of time travel, although as you might guess the results are every bit as chaotic.

One Corporation is a high-tech company operating out of California’s silicon valley in the near future, the 2030s. The company specializes in developing video games and their chief claim to fame is the sChip, an integrated circuit that uses Quantum Entanglement to achieve Faster Than Light (FTL) communications with other sChips. This property allows gamers all over the world to play One Corporation’s video games together without any nasty time delays because of distance. (Actually there are some theorists who think something like that might be possible.)

About ten years after the sChip is first introduced an accident causes a large portion of the network to crash, a gamer spilled his coke onto his terminal. An investigation by One Corporation’s chief scientist, the guy who invented the sChip in the first place, reveals that the crash originated when the coke spilling gamers sChip sent a conformation signal to his buddy’s sChip BEFORE it was asked for the conformation. It seems sChips are not only capable of FTL they can send messages into the past.

Time Travel is one of the oldest and most often used plot device in Science Fiction. In fact it’s been used so often that you have to be very cleaver to come up with a new approach to the idea! (Credit: Penguin Random House)

That’s the neat part about ‘The Dent in the Universe’. Here time travel is limited to only information being send through time, not material objects. Another constraint on time travel in ‘The Dent in the Universe’ is that time travel is only possible through sChips and therefore the farthest back it is possible to go is ten years, when the first sChip was made.

In ‘A Dent in the Universe’ sending messages back in time is only possible through a special integrated circuit, the ‘S Chip’ and hence you can only go as far back in time as to when the first S Chip was made. (Credit: In Compliance Magazine)

Of course it was a part of Stephan Hawkins’ work over decades that showed that information is still energy so it is a material object. Think about it, in a computer information is stored by flipping magnetic fields, something that requires energy to do. So sending information back in time is still sending a material object, the energy to flip a magnetic field, back in time. Nevertheless the unique take on time travel, and the consequences thereof, is the best part of ‘The Dent in the Universe’.

Stephen Hawking spend much of his career wondering if information is destroyed by entering a black hole. His research did show how information is a kind of energy however. (Credit: Nature)

The worst part is the villain, a serial killer of the Bind Torture Kill or Jeffery Dalmer type. I don’t consider myself to have a weak stomach but there were several sections of ‘The Dent in the Universe’ that were simply unpleasant to read, and that’s being kind. There were a lot of gory details that simply weren’t necessary for the plot as far as I was concerned. By the way the idea of a serial killer getting his hands on a time machine isn’t new. Back in the 1979 there was a movie called ‘Time after Time’ where Jack the Ripper, played by David Warner, got his hand’s on H. G. Wells’ time Machine and traveled to 1980s San Francisco. Wells was played by Malcolm McDowell.

All of that is quite a shame because much of ‘The Dent in the Universe’ is well plotted out, something very necessary in a time travel story and rather exciting. The story could have worked just as well without so much graphic gore.

I’m not a big fan of Slasher movies, which was a big problem I had with ‘A dent in the Universe’, the villain was just too gory for my taste. (Credit: Medium)

I do have one other complaint as well. Like many SF stories that take place in the near future ‘The Dent in the Universe’ is filled with techno-talk. The computer gamers all say things like “Rashad’s device processed a D-pad signal at the I/O bus”. Meanwhile the detective’s hunting the serial killer all say things like  “That’s inside the feeding zone. Walking distance to the MPWS station, Good eyes Detective Baker, good eyes.” Sometimes I wonder if authors are just trying to impress their readers with how in tune they are with the language spoken by experts in various fields.

Nowadays every profession has its own specialized jargon. Writing an entire novel using only those forms of speech can be a bit tiring after a while however. (Credit: Tech Talk)

And finally it turns out that ‘The Dent in the Universe’ is just the first installment in another series of novels. I haven’t made up my mind as to whether I’ll read the next installment. As I said  ‘The Dent in the Universe’ had some really interesting parts, as well as some very unpleasant ones.

Book Review: ‘Recursion’ by Blake Crouch      

We all know that our memories are to a large degree who we are. All of our loves, and hates, all of our opinions are formed from past experiences that are stored in memory. I suppose that’s why stories, real and fictional about people with amnesia are so popular. And then there’s always the idea of reliving a memory, of going back to either enjoy once again the best time of our life or perhaps to fix some mistake we made in the past.

The process of remembering something is actually a very complex mechanism involving many different parts of our brains! (Credit: Pinterest)

That last notion is the idea behind ‘Recursion’ a recent novel by Author Blake Crouch. Barry Sutton is a New York City Detective who is investigating a suicide that is linked to ‘False Memory Syndrome’ (FMS) a rare condition where a person suddenly acquires complete and detailed memories of a life they never lived, a mental jolt that causes many of them to kill themselves. Helena Smith is a neuroscientist who is trying to develop a method of recording memories in the hopes that it will lead to a treatment for Alzheimer’s disease, which her mother is beginning to suffer from.

Turns out that what Doctor Smith has invented is a time machine, a way of literally going back into a memory in order to change the past. One interesting thing about the time travel in ‘recursion’ is that making the jump requires the release of the strong hormones that accompany death. In other words you have to die in the present in order to pop back into one of your memories. And if you do change the past those people whose lives you’ve altered will suddenly acquire the memories of their original lives when time progresses to the moment when you used the time machine to pop back, that’s the FMS.

Now the physics of time traveling through memory in ‘Recursion’ is never really explained and the ‘Grandfather Effect’, the logical loop where you go into the past and kill your grandfather as a boy so you are never born so how can you go into the past to kill your grandfather, is barely mentioned. That said once you accept the rules of time travel in ‘Recursion’ the novel is tightly written and very well thought out.

The Grandfather paradox is a logical absurdity that stories about time travel have to deal with, although many simply choose to ignore it. (Credit: Medium)

Doctor Smith’s research is funded by one of those techno-billionaires named Marcus Slade who somehow seems to understand the full capabilities of the machine before Helena does. Slade is the first to try to exploit the possibilities of time travel but it isn’t long before the DoD gets involved and when the technical information for the machine gets hacked there are soon a dozen different entities trying to impose their preferred version of the past and reality itself begins to crack under the pressure of multiple pasts.

Have you noticed how techno-billionaires have become to stock villains of choice in Hollywood lately? I wonder how that got started? (Credit: (l to r) Salon, The Ringer, Timeslive)

I won’t go any further but the breakdown of time itself, along with Helena and Barry’s attempts to fix it are very well written. It fact the whole of ‘Recursion’ is very well thought out and composed.

I do have a couple of very minor complaints. First of all the use of a techno-billionaire as the villain is becoming trite even if Blake Crouch does put a nice twist on him. Second, the novel was written around 2018 and the main action of the story, the breakdown of time occurs in 2018 so it’s already not happened! I would have placed the story at least a few years in the future, say 2028 in order to not have the problem of time making it false even as it was being published.

Other than that I cannot recommend ‘Recursion’ strongly enough. This is one of the best time travel stories I’ve read, right up there with Wells’ original ‘Time Machine’ and Bradbury’s ‘The sound of Thunder’. If you like Science Fiction in general you will certainly enjoy ‘Recursion’ but if you like time travel stories you absolutely have to read it.

Book Review: ‘This is How You Lose the Time War’ by Amal El-Mohtar and Max Gladstone

Somewhere in the Multiverse two ideologies are at war, The Agency is a Techno-hierarchy while The Garden is an organic consciousness. Each organization sends out agents who travel up and down time streams, back and forth across dimensions altering the future here, deleting a bit of the past there in their efforts to bring themselves into existence. Red is the top agent for The Agency while Blue is her counterpart for The Garden.

Such is the background for ‘This is How You Lose the Time War’ by authors Amal el-Mohtar and Max Gladstone. As the story begins Red has emerged victorious in a large battle in some corner of reality when she spies a piece of paper with the words “Burn before Reading” written upon it. Although they have never met Red immediately knows that the message is from her enemy Blue and guesses that the message could be either a trap or an attempt to turn her to Blue’s side. Knowing that even reading the message could be a betrayal to her side she burns the paper and in the fading ashes she reads the first in a series of letters passed surreptitiously between the two time warriors.

As you have probably guessed by now ‘This is How You Lose the Time War’ is a different kind of Science Fiction novel, written in a technique as much poetry as prose, with world building that is both abstract and minimalist. The rules of plausibility, so often broken in Science Fiction are here gleefully ignored. This is a story that is more about style than plot and indeed its plot is really a very familiar one.

I like this drawing showing the two protagonists Red and Blue of ‘This is How You Lose the Time War’. Notice that, like the ying yang symbol there’s a bit of red in Blue and a bit of blue in Red. (Credit: Laya Rose Art)

The two agents are soon passing notes back and forth and of course they soon fall in love, both are female by the way. To be honest I didn’t see the parallels to ‘Romeo and Juliet’ until Shakespeare’s play was explicitly mentioned. “Two houses alike in dignity…From ancient grudge break to new mutiny.” and “Two star crossed lovers” but it was pretty easy to see where the plot was going. As I said ‘This is How You Lose the Time War’ is more about style than plot.

After about a dozen messages between Red and Blue I was starting to find the story becoming repetitious but the authors must have also realized that because at this point the two agent’s superiors begin to suspect that something is going on and Red and Blue are soon put in a situation reminiscent of Romeo and Juliet’s in Act 4. The ending is quite different however and I was pleased that I managed to figure it out ahead of time.

Just like in Romeo and Juliet the two houses cause all the problems for the two lovers Red and Blue. The ending however is quite different. (Credit: No Sweat Shakespeare)

As I said ‘This is How You Lose the Time War’ doesn’t have a very intriguing plot, and if you really like the details of world building you’ll be disappointed. However the writing of Amal El-Mohtar and Max Gladstone is very clever and interesting, again something like poetry.

Of Course Time Wars are right up The Doctor’s alley. But Aml el-Mohtar and Max Gladstone have done a pretty good job with ‘This is How You Lose the Time War’. (Credit: Wikipedia)

And another thing, it’s a quick read. It took me less than two days to finish the novel. So if you’re looking for a light desert after a heavy meal like Dune or GOT maybe you should try ‘This is How You Lose the Time War’.  While it may not be memorable it is nevertheless certainly enjoyable.   

Is Time Travel Possible? Two Physicists from the University of Queensland think it is.

If you think about it, over the last four hundred years humanity’s growing science and technology has given us an enormous amount of control over many aspects of nature. The speed and distance we can travel has steadily increased, as has both the size and number of structures we can build. We grow more food than ever and whether we like it or not we are even changing the weather. Can you say climate change! We have discovered the very code of life itself and begun to understand how to alter and mold living things to suit our desires. We now have many ways of controlling space and material objects that would seem like magic to our ancestors of a thousand or more years ago.

Thanks to our control over Nature we have been able to build ourselves a world completely unlike anything in Nature. (Credit: Invisiverse)

But we still have virtually no control over time. Oh, we can measure it’s passing with an accuracy that, at the risk of repeating myself, is almost magical.  We can’t stop time of however, and although Einstein’s two theories of Relativity do describe how the passage of time can be slowed that slowing requires either velocities approaching the speed of light or immense gravitational fields such as those around black holes.

And even theoretically we can’t go backward in time. In fact many scientists have steadfastly maintained that time travel to the past is logically impossible because of something known as the grandfather paradox.

What is the grandfather paradox? Well it works like this. What if you were to travel backward in time and murder your grandfather before he fathered your own father? In that case you would never have been born and if you were never born how could you go backward in time to kill someone?

In the Grandfather Paradox the very existence of a Time Machine leads to a Logical Absurdity. (Credit: YouTube)

This idea of the dire consequences to the present of doing anything in the past has been the central idea in many Science Fiction stories like Ray Bradbury’s ‘The Sound of Thunder’ as well as movies such as ‘Back to the Future’. Many scientists feel that the logic of the grandfather paradox is so tight that traveling into the past is simply a pipe dream better left to science fiction writers.

Still theoretical physicists and mathematicians looking for solutions to Einstein’s field equations occasionally came up with equations that, while physically hard to interpret seemed to include the possibility of going backward in time. Collectively these solutions are known as ‘Closed Timelike Curves’ or CTCs and where initially discovered back in 1937 by Jacob van Stockum and later extended by Kurt Gödel in 1949. Basically a CTC describes the movement of a material particle that loops endlessly through time and space in a circle. This would imply that the existence of a particle following a CTC would be extremely limited in both time and space.

Every observer exist at a single point in space-time. Since nothing in the Universe can move faster than the speed of light that observer can only be effected by events within his Past Light Cone while he can only effect events with his Future Light Cone. (Credit: Wiktionary)
Under Certain conditions however, such as near a black hole, a light cone can be tilted. Continuous tilting results in a Closed Timelike Curve. (Credit: SlideShare)

Physically it is hard to understand how any particle following a CTC could interact with other more normal particles. Such a path in Space-Time would seem to imply the possibility of events happening without causes since to the normal particle the CTC particle can appear to pop into existence without reason. At the same time to an outside observer a particle inside a CTC might appear to experience an event before its cause!

Because of such paradoxes many physicists expect, or perhaps hope that an eventual unified theory of gravity with quantum mechanics might eliminate CTCs as even being mathematically possible. Other physicists however prefer to try to make sense of these weird solutions to the field equations.

One of those physicists is Germain Tobar, a student at the School of Mathematics and Physics at the University of Queensland in Australia. With the assistance of his colleague Dr. Fabio Costa, Tobar has analyzed CTCs in such a way that he maintains opens up the possibility of time travel into the past.

But what about the grandfather paradox? What about the problem of actions in the past changing the present? Well in Tobar’s analysis what happens if you were to try to change the past then the universe would react so as to avoid the paradox, to repair the damage you have caused in other words.

I won’t go into the math. (Actually I am going through the Math, trying to remember what I learned in my course in General Relativity but I won’t impose it on you.) However, it appears to me that in Tobar’s treatment if you were to go into the past and kill your grandfather then when you returned to your present you would find yourself with a different grandfather or something equivalent. Sounds to me kind of like what Marty and Doctor Brown did to repair things in ‘Back to the Future’ except that this repairing would occur naturally, automatically.

I have to admit I have real problems with that idea. Remember, the past starts just an instant ago! What if you were to step into a time machine and go back ten minutes and murder yourself just as you’re stepping into your time machine? I’m sorry but I can’t imagine how the Universe could repair that damage, how it could change things so much so quickly in order to somehow avoid the paradox!

Maybe it would work something like this? (Credit: xkcd)

Time Travel would be the ultimate power, the ability to undo all of our mistakes, to right all of the wrongs we’ve done. Perhaps for that very reason it is the one power that will always elude us.
