Question: Since we are all made of fundamental particles, would it ever be possible to split ourselves apart and teleport our selfs across a vacuum or free space and be reassemble ? If we were able to keep track of the millions of fundamental particles that we are made of?

Great question, thanks!
Firstly, teleportation HAS happened in the form of quantum teleportation, but only with individual fundamental particles, and at the most one atom!
To get a handle on the complexity of your question, I had to find out how many atoms there are in a person, and its about:
7,000,000,000,000,000,000,000,000,000
That’s a lot! Now each atom might have hundreds of subatomic particles, but for now lets work just with the atoms. If we wanted to teleport someone we’d have to not only keep track of all of those particles but we’d have to be able to reconstruct them into EXACTLY the right place. Even a tiny bit out and we’d probably give the person some neurological or genetic disorder… probably it’s the reconstruction bit that is the most difficult. I know from my work that aligning things to within the width of a hair is extremely difficult and time consuming… so I have no idea how you’d do that part.
So I don’t have a final answer, I’m not saying we could *never* do this but I’d have to say I don’t expect it to happen in my lifetime!
