Off topic for a software blog, but just a quick thought - if matter can be converted into energy and reconstituted back into the exact same form of matter again (all particles arranged as they were before), then yes...that would be one way of moving mass at light-speed. Ah...providing that the form of energy could be moved at light speed. Might take a while to convert matter to energy and back again though.
It's kind of like a chicken and egg problem isn't it? What converts the energy into matter? Wouldn't the transducer need to be in position at the destination first (e.g. light-years away)? Or perhaps there is some way to remotely manipulate particles from afar in such a way that they can be rearranged into a predefined arrangement. And only the energy would be sent across. Guess that would be more or less making a copy of the matter rather than actually moving it via its energy form. Guess that would be more or less cloning matter than transporting it.
Bah, can't help myself, let's do a software thing...they say that a 64-bit number (a long) can hold a number bigger than all the atoms in the Universe times 200. And we can store those numbers all day long. How many numbers, bits, etc...would it take to store all the atoms in a frog? Assuming we had the necessary transducers to take in a signal and reconstruct the matter, what would it take to beam up a frog Scotty? Assume also that we can digitally encode matter and send it to the other side. Hint: Apply problem solving technique from last post to solve this problem.
Someone should make a GitHub project out of this...oh wait, I'm on it...here it is.
