I think quantum teleportation could work.

But I think it would be very important to make very sure there were no flies in there with you when the experiment begins....

- sorry, just couldn't resist!

Answerer, you realise that in the context of scientific methodology, you would actually remain agnostic to all open QM interpretations, including the consciousness variant of the Coprenhagen Interpretation ? Although out of favour, it’s not disproved & still commands discussion. I think only the Hidden Variables models are close to being disproved.

Similarly when you dismiss the TI,

… you actually need to do it scientifically rather than simply because it conflicts with randomness. And when you “don't believe in the 'absolute power' of the observer”, theists can rightly argue that your scientific belief is little different to their religious belief.

There’s a lot of widely differing models out there. The problem is that few offer provable predictions to give them veracity.

Answerer

Well, those interpretations are not yet experimentally proved. Furthermore, most of this interpretations can't be reasoned logically in a scientifical way. These two factors give me enough reasons to see the incompletely or invalidness of those interpretations.
If an observer has the power to define the outcome of a quantum state, why does that power come from? Mind? Or soul? Therefore, clearly, this
is a violation of scientific reasoning(which doesn't include spirtually factors) and I supposed no one could really give that 'power' an exact scientifical source and I think this is why Einstein reject the CI.

The photons actually did not transfer/teleport from 1 location to another. There are certain conservation laws which apply to sub atomic particles.(Excuse me, I am no scientist, but this is my take.) When these particles are separtated, this must conserve motion, spin, etc. So if you causea change in one particle, i.e. direction spin etc. the other particle must also change according to Quantum theory. This particle will change, no matter where it is located in the universe. Apparently the beam was destroyed in such a way as to create a new beam elsewhere. It was never really transferred, just duplicated, with the original being destroyed. Seeing how complex this is, I doubt seriously if they could ever do this with atoms. Am I wrong on this? Some science nerd help me out.

Interesting thing about weather prediction. I remember when computers would one day tell us the weather anywhere in the world at any date in the future, even 10 or a hundred years from now. Turns out, they can't do it, and most likely will never do anything like that because there are too many variables, like the wings of a butterfly.

There was an article in "Scientific American" on this subject about a year ago. It is part of the reason I didn't renew my subscription. There was only wild speculation thinly guised in science.

Answerer

Well, do anyone have an idea to why the original object had to be destoryed in order for teleportation to take place?

I'm no expert on quantum theory, but I gather that it is utterly deterministic, possibly the most accurate theory we've had to date. The probability of one thing or another happening only occurs when we move quantum phenomena into the classical world.

I would agree with that and add...
The easiest way to describe QM is to say that everything is deterministic. It's only when one assumes free-will of the observer that there is a need for extreme interpretations.
