Science fiction as I understand it is when you answer a “what-if” question and follow it through its consequences on society. In The Fly, the question asked is “What if human beings can teleport?” The answer explored in the movie is that while at its best the technology is convenient, the invariables associated with the technology are too dangerous to consider. In short, you never know if something will come out on the other side, or, if it does, what. But there is a much greater issue at hand with transportation not addressed in the movie. It all boils down to the fact that your body technically dies. To understand this, one must look at the hypothetical physics behind teleportation.
The standard science fiction teleportation device consists of two parts, the entrance portal and the exit portal. When a subject enters the entrance portal, every single atom in there body is identified and their information is sent to the exit portal. The exit portal, using the information sent by the entrance portal, constructs matter by rearranging the atoms in that area. The matter itself is not sent, only the information on how to replicate it with existing substances on the other end. It is like a matter fax machine. However, unlike a fax machine, the original is destroyed in the process. Yup, completely disintegrated. Technically, your body dies in the entrance portal, and a completely new body reappears on the other side. I have been careful to say that it is your body that dies, because I do not believe that you, your self, dies. This is where my roommate and I disagree. We got into a heated debate on whether or not “you” die, what “you” is, and if would use the transporter.
I understand that your body does not actually teleport from one space to another. That point is clear. My roommate thinks that because your body disintegrates, you die. That is on the supposition that your body is the essence of you. If transportation works like it theoretically should, your consciousness, your thoughts, your memory, your personality—everything, is transported. It is the concept of a thing that make it a thing, not its physical properties. Physical properties (the only thing truly lost in the disintegration process of transportation) change all the time: skin cells die off and are replaced. The hair you have now is not the same hair you had two years ago. If you look back at old photos of yourself, you could say “My hair was longer/shorter then.” In reality, your hair did not exist back then, it was a completely different set of molecules, but it is essentially still “your hair.”
Let’s dissect this even further; say your arms got cut off and were replaced. You’d still be you. Now what if they replaced them with exact DNA replicas of your old arms? You’d still be you. Now, what if they replaced more than just your arms? What if they replaced every single part of your body? It’s a more extreme case, but the same thing. Furthermore, what if they did this instantaneously, with all your new body parts constructed elsewhere while your old ones disintegrated in the blink of an eye? You’d still be you. That is exactly what transportation would do.
My roommate insists that transportation is death and that he wouldn’t want to die. Death is as death does. As we understand it in our day and age, death is loss. It’s separation, mourning, emptiness, a change in others’ lives. These are the reasons we don’t want to die. If these don’t occur, why would it matter if you “died” in the transportation process? If someone were to say that they were going to cut off your arm, but it was going to be replaced right away with an exact copy, you wouldn’t feel an ounce of pain, there wouldn’t be permanent scars, and that neither you nor anybody else could even remember the event, what would be the problem? Technically, you have a completely new arm, but what does that mean if there’s no change? This is why I don’t have a problem with “dying” during the transportation process.
