>>13954930Okay, first I am going to assume that by teleportation we mean the following: determining the entire molecular structure of a human body, disintegrating it in a way that is not painful, transmitting that information (the chemical structure) to a far away place and assembling it from scratch in a way that doesn't cause pain while at the same time being fast enough that cells don't die because of the lack of oxygen and nutrients and that it is actually useful. I guess that you can already imagine the kind of challenges that you have to deal with.
My TL;DR answer is that we don't know enough about biology and chemical synthesis to do it.
First of all, I am not a scientist, so take everything that I say with a grain of salt. That being said, the first problem is determining the molecular structure of the human body. We still can't determine the structure of systems that are so complex. Determining the structure of DNA led to a Nobel Prize. I believe that the structure of the ribosome (an important component of cells) led to another one around 10 years ago. We are still working at this small level, so an entire human body is out of the question. See pic related, which shows what trying to determine the structure of the ribosome was like
Assembling molecules is a hard problem too. We tend to think of matter as lonely molecules because of pop-sci, but the truth is that even microscopic pieces of matter are a chaotic swarm of particles moving in all directions. When you want to synthesize something, you need to make these randomly moving particles react in the way that you want. You can't "assemble" compounds atom by atom. The synthesis of ammonia led to a Nobel Prize in 1918, even though the compound only has four atoms (NH3). The synthesis of Vitamin B12 was another big breakthrough in 1972 even though the molecule only has 181 atoms (chemical formula: C63 H88 Co N14 O14 P). Imagine synthesizing an entire human body, which has more than a billion atoms.
