Thanks. Scientifically, I don't see how teleportation will be ever possible the way the Trek depicted it. From what I've read even if many of the problems related to computer speed and storage are solved in the end basically the process would be to create a complete copy of your body including your memories and incinerate your existing body. And then reconstruct that copy as a perfect replica some where else.
Couple of things occur to me if that ever became possible:
1. Humans could become immortal by re-creating themselves at a younger age as a clone with existing memories
2. Who in their right mind would want to transplanted into a clone of themselves?
Because of these and I'm sure other moral issues surrounding cloning and in theory immortality - these issues would make teleportation problematic regardless eveb if it is ever technically feasible.
As an aside - even in Trek they are inconsistent on this issue. In Enterprise the inventor of the Transporter [forget his name] strongly refutes the notion that it's cloning.
However in Next Gen - we have at least three episodes that suggest that cloning is at least part of the transport process.
The episode where Thomas Riker is created. And the episode in which Dr. Polaski [sp?] is de-aged using the machine.
And the episode in thish Guinian et al are turned into children and then turned back into adults.
Another interesting article about how it is impractical. However it's interesting to note that the author says only 1 zetta byte exists world wide when we know now the NSA is building a 5 zetabyte storage facility right now
Destructive scanning of a body, transmitting the information, and then reconstructing the body: To have a scanner that can record the position of every atom in the body to an accuracy of the order of the size of a hydrogen atom would require position accuracy of about 10-10 meters. To get that accuracy over a distance of order 1 meter, this would require 30 decimal digits, which would be about 100 binary digits per atom. However, there would be a lot of redundancy in this data, so let's be optimistic and assume you could compress this down to 1 bit per atom, so we still need approximately 1027 bits of data to just specify the positions of all the atoms in a human body. According to Wikipedia (Exabyte), the approximate data storage capacity of all the computers and storage devices in the world today is roughly 1 zettabyte = 1021 bytes = 1022 bits. Therefore, the data for the scan of one human would require at least 10,000 times the total storage of all the data stored on Earth right now.
