Why Star Trek transporter technology would never work in the real world or even in the Star Trek world:
Let’s start off by thinking about the food replicator. The technology is similar to transporter technology. In the food replicator, matter in the form of atoms and molecules are rearranged using a pattern in order to produce an item of food. For example, if you say “ribeye steak,” the replicator will look in its memory banks for the pattern for “ribeye steak.” Then it will take the necessary atoms and molecules to form a ribeye steak. It will take carbon, oxygen, hydrogen atoms, etc. all the building blocks of that steak and then put them together in the right order to make a steak. It may even just convert energy into the constituent subatomic particles first, then make the atoms, then make the molecules, then produce the steak.
But here’s the key thing. That steak never came from a cow. It didn’t exist before you ordered it. It’s taking the basic building blocks of matter and manipulating them to make something you want. It’s similar to taking Legos and using a pattern to build a house. The house was just a jumble of Legos until you built them into a house. My point is that the replicator uses energy to create things that didn’t originally exist.
Let’s put that aside for now.
Let’s say you’re unconscious and I want to bring you next door to my neighbor’s house. You’re hard to transport, so I cut you into two pieces right through your midsection. Do you think you’d survive the process? Do you think I could put you back together and you’d be alive when you got to the neighbor’s house? What if I cut you into 4 pieces? What if I separated you into 1,000 pieces? Or 100 quadrillion?
So, the transporter, supposedly breaks you down into your constituent subatomic particles, then converts them into energy and then beams them somewhere else. Why, if you cannot be separated into 2 pieces and survive do you think you’d be able to survive being separated into trillions upon trillions of pieces?
Let’s go back to the Lego’s example. Let’s say you have a Lego house. Then you take that house apart and put the Legos into their individual pieces. Do you have a house? No, you have a pile of building blocks.Then you use a pattern and make the house over again. Difference is, houses aren’t alive. Neither are building blocks. Neither are individual atoms and subatomic particles and energy.
What if I took all the carbon atoms out of your body, along with all the other atoms and piled them on a table, would that pile be alive? No. What if I took those atoms and then turned them into pure energy, would that energy be alive? And if so, would it have your personality?
Here’s the sober reality of Star Trek transporter technology: A machine scans you and makes a pattern from all the atoms and particles in your body. Then it separates all the particles, in effect KILLING YOU, turns those particles into energy that is then beamed somewhere else. Then, using the pattern created earlier, the basic building blocks of matter (which are not alive) are then reformed into a replica of you which was never alive before the atoms were put together (just like the ribeye in the first example).
Simple version: You—You broken into building blocks: killing you—Building blocks used to make copy of you from your pattern.
The reality is that you die and a copy is made. There isnothing magic to keep you alive when you are separated into trillions of pieces.
Here is the other horror: This means that in the Star Trek universe, anyone who has ever used a transporter is dead and a copy of them is running around thinking they are the original person (or the last copy that went through a transporter.) Apparently, the transporters are so good at scanning that it knows the properties of all the particles so that the copy has the memories of the original. So, there is no way to tell them that the process is killing them. Why? Because the people who would know are dead!
Example: Let’s say James Kirk is born, then grows up to become Captain. Then he steps into a transporter. His body is turned into building blocks thus killing him and then a copy of him comes out the other transporter pad. The copy has all the properties/memories he had and doesn’t realize he’s not the original. The original can’t say anything because he died when he was torn apart. Then, the copy goes through a transporter and he gets killed when he is torn apart and a copy is made again, and so on and so on. Depending on how many times someone went through a transporter they could behundreds of generations away from the dead original.
Sorry, but you just can’t get around the fact that when you are turned into space dust and energy, you will be dead.
