Time Travel

Michael Coughlin and Time Travel

This intriguing idea is from Michael Coughlin!

* * * 

I’ve been working on an article for Lisa and Mused for years.  It is not going well. The subject is complicated and has a vast literature.  I want to summarize everything ever thought of in a few  paragraphs. So I must take a bold step to at least get started even  tho I can’t write logically flowing steps the way I’d like. I reserve the right to make radical changes, especially if you send me suggestions.

I still can’t find an easy way to get 64 characters per line. 

Michael Coughlin


Years ago my mother told me she did not enjoy science fiction stories about time travel. The idea was too impossible. How could I have a mother with such a limited imagination? I decided to think of a way to build a time machine and expand her horizons. After a while I realized all you would have to do is place every atom and subatomic particle in the universe back exactly where it used to be and travelling in the same direction at the same speed. Oh, wait a minute, that is impossible. It is even more impossible than anything I’d ever read of why a time machine is impossible. My mother was right! 

Making up a story about time machines creates many paradoxical ideas. The past has never gone away and the future has a short cut to visit it. Where does our imagination stop and reality start?  The past does not exist, except in our minds. The future has yet to happen. What we see is what we have.  And not only can’t we put everything back the way it was at some distant time, we can’t know exactly where everything was there in the first place. 

Travelling forward in time presents a different set of impossibilities then going backwards. Actually it is possible to travel forward in time a little bit as shown by Einstein’s theory of the relativity of simultaneity. Global positioning satellites need to take this into account. Suppose you wanted to make a big trip into the future? Then Einstein’s paradox of the twins comes into play. Build a space ship that can accelerate constantly forever. This is, of course, not possible. But I think this idea is more interesting than the usual fictional space ship magic of disappearing from one part of the universe and instantly showing up in another. As this space ship travels thru the galaxy constantly accelerating at 32 feet per second per second, all the people on-board will comfortably experience the same force they do on earth from gravity. Makes filming the story very easy. The space ship will travel faster and faster till after only a few months it will be travelling close to the speed of light. The passage of time and the view of space will be radically changed. After a few years the ship can be anywhere in the galaxy or even beyond. Half way thru the trip turn the ship around and decelerate at 1 G. Then travelers can explore their chosen stars and planets at their leisure. Reverse the procedure and come back to Earth. Surprise. Time on Earth has gone forward much more than time on the travelling space ship. 

The idea of a 1 G space ship was written about years ago and it didn’t catch on. Too bad since it might have been an educational lesson for the theory of relativity. What was not known at the time is that the universe is not as empty as it looks. The night sky looks really dark and black but we now know there is a faint glow of light at various wavelengths. When the space ship accelerates to interesting speeds this light becomes blue shifted and strong enough to destroy things. Also the universe is filled with unknown “dark matter” that could also collide with and destroy speeding space ships. Then there is interstellar ordinary matter of various sizes. Colliding with a grain of sand while travelling near the speed of light is a very bad thing. Never mind colliding with a rock or comet. 

Time machines have nothing to do with “science” fiction. They are fantasy. Mark Twain had the right idea when he wrote “A Connecticut Yankee in King Arthur’s Court”. No machine needed, just a strong blow to the head to go back and then the right spell cast by Merlin the Magician to return. Time travel is an exercise for our memory and imagination. You can’t put things back the way they were. But you can look back and decide how things could be different so you might know what you should do when similar events show up. 

The laws of Physics are the same for time going forwards and backwards. Maybe time does go backwards, sometimes, for a little bit. Time might not apply to subatomic particles colliding. Maybe time does not exist and can be replaced by rules of how parts of atoms bump into each other. Physicists want to compute the state of the universe forward and backward without limit. And also account for things that happen in the smallest possible spaces in the shortest amount of time, as well as the largest things we can see and beyond what we can see. 

This is not a subject only for Physicists. Impossible time machine stories are a refection of how we perceive reality as well as the passage of time. In many stories, the hero goes backwards and creates a disaster that prevents him from returning to the time from where he started. Perhaps other events occur to cancel his actions, or he needs to do something amazing to happily return home. The author has decided that the passage of time actually cannot depend much on what we do. Our lives are fixed by fate and  we must follow a path that we have little ability to change.  At certain places and at certain times people have thought that way.  Now that I have invented an imaginary impossible time machine, I can look at things in a different way. It is not possible to go back in time since all the atoms can’t be put back where they used to be. At least in the past the atoms were in a certain place at a certain time. Travelling into the future is a whole different situation. The atoms of the universe have never been where they are going to be. Our impossible backward going time machine can’t just shift into reverse to go forward in time. It must be able to calculate where everything is going to be to put it there. An impossibility piled on top of another impossibility. 

We can do much more than cavemen could, not because we are more intelligent, but because we know more about the world and how things work and don’t work. Learning about what is impossible is as important as learning what is possible. Right now the science of Physics has not neatly connected the radical new ideas from the 1920s of quantum mechanics combined with general relativity. Thinking about time machines is another way to try to learn what time really is and how to keep track of it.

Horror Stories

Hurrah! Hurrah! Victory!!

All seven horror short stories plus the full horror compilation book are now loading live on Amazon. And there’s still over two months until Halloween!

I actually got a project done ahead of schedule! It can be done!

Three Free Books on Publishing

I’m running a FREE promotion on Kindle for books 3-4-5 in my Author’s Essentials series. Get whichever ones you want or grab all three. These are part of what I teach in my in-person free writing seminars. Ask with any questions!

Book 3 on Choosing a Path is here-


Book 4 on Traditional / Large Press / Small Press publishing –


Book 5 on Self-Publishing step by step (including Amazon paperbacks, Amazon Kindle, and other systems) –


Free Mentoring Session

Reminder! Free! Tonight! I’ll be doing a LIVE video mentoring system from 6-8pm EST at


 – it’s free to participate. Ask me anything about writing, editing, book cover design, publishing, marketing, and more. You don’t need a video camera or microphone or anything – you just type your questions. This will be a test run for me to see if it’s an efficient way to help many writers at once. I also have free in-person seminars but I know many of you aren’t in Central Massachusetts to attend those. I’d love to hear any feedback or suggestions on this! And I hope to see you tonight as part of my test 


Flustered Flamingo

Hurrah! My life has been so busy that my to-do list got away from me. I’ve FINALLY hit publish on book 10 in my cozy zoo mystery series. It should be live soon! Then I’ll need to re-edit all ten books to link properly to each other and to the full compilation. And then this series will be set, at least for this arc! One step at a time! If you haven’t read book 1 yet, it is FREE and here: https://www.amazon.com/gp/product/B014GRKH0K/

What are you up to?

Writing & Cover Design Books FREE

For the next five days, I have put the first two books in my Author’s Essentials books FREE on Amazon. You can download these both wholly for free now. I suggest doing that before Amazon ends that free period.

Please share the news with any family and friends.

Here’s the link for book 1 on writing and designing the book: https://www.amazon.com/Writing-Designing-Successful-Book-Experienced-ebook/dp/B01MRRVFLB/

Here’s the link for book 2 on designing the cover:

I am doing this as part of a push to begin offering more services online. Up until now I’ve only helped people via the in-person library seminars. That is nice, but some people end up driving an hour or more each way to get to one. Also, there are many people who can’t attend due to scheduling issues or they are just too far away.

Here are the two options I’m trying out.

First is Patreon. I will be offering various options here for readers to support my writing and for writers to get personalized one-on-one support with me, via email or phone or Skype, to make progress on their writing, publishing, and marketing. I’m new to Patreon, so please let me know if you use that or if you’re able to help me test it. I am still in the ‘review’ stage so all the options are not yet live. 

Second is Twitch, which is a live video streaming service. You will be able to log on and watch me, live, as I talk about writing, editing, publishing, and marketing a book. You can type in questions live for me to answer right there for you. I’m new to Twitch, so I’d like some guinea pigs (ahem, writers) to test this out with me. Please let me know if you’re willing to give this a try!

My next free in-person seminar is this Tuesday, June 4th, 2019 at the Sutton MA library from 6-8pm. The focus of Tuesday’s seminar is on all forms of publishing. Traditional publishing. Small press publishing. Self-publishing. I’ll go step by step through screens to show how it works. Come on out if you’re free!

Let me know if you have any questions!

Diner Days are Here Again

Diner Days are Here Again

I’m so so thrilled! My audio narrator for my Asperger’s mystery series set in Worcester lunchcar diners just finished book 2. That book is Diner Days are Here Again. I had tears in my eyes laughing while listening to her reading! She did an awesome job. It should be live soon.

Book 1, Diner Deeds Done Dirt Cheap, is free in Kindle format. Let me know if you’d like a coupon to hear book 1 for free in audio!

I’d love one more review to reach 30 ratings!
