Nothing can go faster than the speed of light. Or so goes the conventional wisdom. Michael Salomon is a physicist who works with tachyons, which are particles that not only travel faster than light, they travel at up to 5 times the speed of light. His experiments with these faster-than-light particles prove that breaking the light speed barrier causes travel backwards in time, so that you get to where you’re going before you started. So, if this review prompted you to read “Multiverse” while traveling with a tachyon, you would find that you had already read “Multiverse” before you read this review. Effect paradoxically comes before cause.
Somehow, Professor Salomon figures out a way to use this tachyon effect to send people back in time. Another character, Alicia Yoder, has figured out how to encode memories, and when she teams up with Professor Salomon, they send these memories back in time to their younger selves, creating a situation where people can remember the future. You can see now how all this could get rather complicated, as people try to change the past so their future bad memories don’t come true.
Of course, the government is involved in these experiments, and wants to use the technology for its own nefarious ends. When Michael and Alicia realize this, they try to change the past and erase the technology from ever being developed. Along the way they go through different timelines, and they have different relationships, with different levels of intimacy. Michael also has a wife and child and sometimes is divorced and sometimes has a happy marriage.
The first part of the novel may turn off a lot of readers with all the physics talk, but that does end eventually, and the story becomes more action and adventure oriented without the physics mumbo jumbo. Although, the concepts this book explores have been done several times before, it is still an interesting read, and if you start now, you may find that you already finished this book before you got to my review.
