That mostly depends on the specific definition used for "touching", but yeah, that relates to the "various field effects" I mentioned before. Van der Waals effects and exchange interactions in particular. And it's also more complex than molecules not wanting to touch each other. At molecular scales, electron orbitals near each other attract and repel each other due to electrostatic polarization (both from asymmetrical bonds and induced fluctuations in symmetrical bonds). This (Van der Waals) is responsible for things like surface tension, and the particulars of how molecules interact like this are why water mixes with alcohol but not oil, and why Teflon (coated with uniformly highly polarized fluorine atoms) doesn't mix with much of anything. But the Pauli Exclusion Principle also comes into play. It is the reason why electrons form different orbitals, and it also means that two of the same kind of orbital in different atoms can't occupy the same location. When atoms get very close, to the point where the orbitals would start to overlap, exchange interactions act to push them apart, so that the orbitals act a bit like springy rubber balls that bounce off each other. This is what makes solids and liquids relatively incompressible, though large pressures (as found inside planets and stars) can noticeably compress them anyway. Extreme pressure can cause the orbitals to collapse and form degenerate matter supported by a stronger exclusion effect. So like I said, it kind of depends on whether or not that counts as touching.

Anyone know if quantum entanglement allows 'teleportation' - of matter or information. I've heard a lot of conflicting things about it. According to Einstein's theory of relativity, neither matter nor information can move faster than the speed of light, but the "update" happening when entangled atoms are observed happens instantaneous, regardless of distance. But apparently information isn't actually transmitted, or it is, or something.

Point being: Lag free multiplayer with people in Australia, yes/no?

You mean this?





Also, science.
It did, back when I was 15 and I found out how it really worked.

It allows teleportation of quantum states, which is kind of like teleportation of matter and information but different in rather important ways. You can read about it here, but the gist of what relates to your question is that matter does not move from Location A to Location B, and the reproduction of quantum states from Location A at Location B requires a classical information (lightspeed max) communication channel between the places involved. As far as Location B is concerned, entanglement-based spooky action at a distance isn't apparent until the classical signal from Location A arrives with information about the entangled partner. With that information, the entangled partner at Location B can be given the same quantum state as a particle at Location A, so while the particle hasn't moved from A to B, it's functionally like it has. This isn't useful for a Star-Trek style teleporter, but it is useful for quantum computation.

No. Also, the bit Q.U. mentioned about special wave propagation setups isn't useful for transmitting normal communication, and is unrelated to quantum teleportation.

is there any way for things to teleport?

Difficult to say. Technically it would be possible to scan an object, then destroy it, send the information of it's composition elsewhere and reconstitute it in the same manner. Would it be the same object though? It would have been made of different bits of matter, although of the same kind. Would "teleporting" you like that still re-create YOU on the other end, or would that be someone else is more of a philosophical question than a physical one.

All that's required is the digitization of the consciousness, and the brain's contents.

Then, you transfer to new body, and bingo.

There ya go.

Not really, at least in the Star Trek sense. Real physics has logistical and metaphysical problems, as Q.U. pointed out. The teleporter was put in the show to save money and effort by not requiring people to go around in shuttles all the time, but for it to work the way it does, it should be one of the most powerful weapons/tools in the ST universe if not constrained by the needs of the plot (e.g. who needs antimatter or fusion when matter can be converted to energy so easily?). The energy and control involved in macroscopic quantum-level rearrangement of matter is enormous, and a civilization that can do that should look more like the Culture.
