1. i was watching a clip the other day with Michio Kaku on teleportation (you can find it on youtube). in the clip, he stated that scientists have succesfully teleported an atom across the Danube and even as far as 100 miles.

i also saw in another clip that it takes around 8 minutes for light from the sun to reach earth and that nothing can go faster than light (dunno if that's true) and for something to seem to do so involved time dilation or time travel.

my question is this:

if i teleport myself from the sun to earth, i would be, in essence, traveling faster than light since it would take me 1 seond (?) and light 8 minutes (this is where i'm unsure). but since nothing can do this, doesn't it mean that i'm actually traveling in time?

i'd love to hear your thoughts on this.

3. Although this is very hypothetical, I would assume that this depends on how you get there. If you really travel through space - I do not see, how this would be possible without violating relativity - then yes. But if this teleportation is only a jump between two points in space without actually passing all the points in between, then I guess no. But as I said - it is very hypothetical.

This experiment only involved a single particle. Extrapolating this to the macroscopic space would be similar to expecting a quantum-mechanical double slit result on macroscopic bodies. So, if you manage to pass a double slit and produce a fringe pattern on a screen, I'd say, you can teleport, too.

well the way i see it, if we ever managed to teleport a macroscopic body, we would have to do it on a quantum scale. by that i mean, break the body into pieces down to its quantum state meaning you could produce the fringe pattern(right?).
also, in the teleportation involving the single particle, do you know if it was a jump between two point or all the points?! and if it was through all the points , again, would it not have travelled through time?or does it not matter on a quantum scale. does the theory of relativity or which ever it is not apply?

forgive me if i wrote anything silly but i'm not to good with physics. just have a very basic understanding and an advanced curiosity

5. I'm fairly certain that the teleportation of a single particle was done with entanglement. That is, they didn't exactly teleport a particle, but they teleported it's quantum state. Since that's all that really matters, it looks and acts like the particle was teleported.

6. How did the guy know that it is the same atom?

I read a few theories on this: (but none seem remotely possible)
1. You have a copy machine on one end and a somewhat printing machine on the other end.
The copy machine copies the body to be transported down to the to the atomic level.
The somewhat print machine then reconstructs the copied body.
Comment: This is way tooo complex. An error can make you end up with butt in your face.

2. The famous breaking of time-space continuum.

3. The use of light and quantum physics.
Comment: Seems to complex for our understanding as well.

7. If you haven't read Physics of the Impossible yet I suggest you do. It's by Machio Kaku and has an entire chapter on the possibilities of teleportation on a macro scale.

8. There are tons of possibilities. The question is, which of these is actually proven. We may have foresight of what is to come, but do the path to that feasible enough for our resources and limitations.

I would say yes. It's like traveling out of time a little. But, if there are other species in space who have an other time set according to the natural conditions on their home planet, than, well, you would probably travel in time again. Not in earth time, but might be you'll meet interesting new folks.
