Time Travel with Tachyons

The design for a theoretical teleporter made me think. Here’s the basic idea: Scan the contents of the teleporter at the subatomic level, including their energy patterns, dematerialize it, and send the energy along with the data to be rematerialized in a new location. Would it be necessary to actually send the energy produced by absorbing the object? What if you only sent the scan data, and used energy from another source to rebuild said object?


Heisenberg’s Uncertainty Principle

I’ll break it to you easy. . . or not. You cannot scan all the properties of a particle governed by quantum mechanics. Basically Heisenberg’s Uncertainty Principle states the more you know about the velocity of a particle, the less you can know about its location. This may make things difficult to make a teleporter, but I’m sure some physicist will come up with a brilliant idea around this in the future.



To those who don’t know, tachyons are theoretical particles that violate the speed of light, therefore locality, and henceforth causality, and even more henceforth travel back in time. It would probably take a lot of energy to generate them, so make sure you have a good reason to travel back in time.

Bad Reason
I’ll dig the pool, but you’re filling it with saliva yourself. I know I always say that, but this time I MEAN it.

You could send them back through time, with the first few describing what point in time they’re destined. The following could be a binary message about what is to be rebuilt. By standards of physics, since the new creation is exactly the same as the old. See more on this here.



  1. Tachyons don’t necessarily exist.
  2. If they do, they might not be able to be aimed at a certain time.
  3. Heisenberg’s Uncertainty Principle.

The idea is in place. Even with difficulties encountered, we will find ways to cheat them. It’s human nature.
