Teleportation. The development of this tech could be monumental in man's exploration of the galaxy.

Let us say that man creates a Mars colony/space station and we start teleporting people and materiels there. Speed of light correct?

Then from that point they leave to go to Jupiter's moons. Set up another space station/colony. Teleport there. Then Pluto...then outside our solar system.

What do you think of teleportation in this light Siro? Yes it is probably decades away if not longer but the development has started.

Edit: Even at the speed o flight it is not instantaneous over this vast distances. How would that affect a person's psychological state? Would they have to be sedated?

Reminds me of a short story I read about the future and teleportation. This society develops teleportation between planets but as it was developed they discovered that all life, even down to rats, birds...had to be sedated first or they went completely insane and dies shortly after arrival. So in this story there is mandatory, enforced sedation before teleportation.

Well this family is going on a vacation and getting teleported. The son (like 10 or so) has never been teleported and is scared. Well he doesn't want to be sedated so he fakes taking his meds and pretends to sleep. All his family goes thru and is woken up on arrival. Then his turn comes and when he arrives he is insane and dies after a minute or two. but as he is dying he keeps screaming about eternity. Apparently to the mind the teleportation is literally eternity. The brains feels as if it has had 0 stimulus for eons and then bam. It is all back and the brain basically crashes and the person dies. Family watches has their son dies in front of them and realizes he has experienced eons of isolation and the eventual torture of that.

That kind of entanglement based teleportation is probably not possible for transference of physical goods. Let me dig in my post history to find where I explained the phenomenon since I don't have as much time to explain now.

So each entity in the universe exists as a wave described by a wavefunction. These wavefunctions contain all the properties of the entity. So a proton, for example, has a wavefunction that can be used to calculate its energy and charge and so on. But a proton is made up of other particles called quarks. Quarks also have wavefunctions. In a particle accelerator, like the LHC, protons are smashed together so hard that they disassociate into other particles, including quarks. Those particles that come out of the protons are all entangled with one another. Why? Because they came from the same source wavefunction. The proton had a charge of +1. All the particles that come out of it must have a charge that add up to +1. It had a certain spin, energy, momenta, and they are all subject to conservation laws. So when physicists gather all the signals they received from smashing a particle, they add them up. If they add up to less than the original particles, then a discovery is possible!

The opposite is also true. Just like one particle can break apart into a bunch of entangled particles, a bunch of particles can be combined into a single system. In other words, you start with two particles, and you put them in a situation where their once separate wavefunction merge into one. The original wavefunctions can no longer be separated from the combined one. It is now a single system that contains the combined properties of the constituents (similar to the way quarks and gluons make up a proton).

Taking the simple example of spin, you start out with one electron with an up spin and another with a down spin. Once the two electrons entangle, they will form a new entity with zero spin (up + down = zero). Now you perform a spin measurement on the first "particle" (on the entangled system), and since nature won't allow you to see a particle than is spinning up and down at the same time, it will either give you up or down. But now the wavefunction that contained both spins is depleted! If you measured one spin as an up, then all that remains in the function is the down spin. The second particle is forced to take the remaining spin. So knowing the property of the first will ensure you know the property of the second.

This works for all properties, not just spin. For example a photon with no charge can transform into an entangled positron-electron pair with zero net-charge, even though both components are charged.

So the "teleportation" of properties across two particles happens instantaneously, and not at the speed of light. However, information is bound by the speed of light. You can't just entangle the particles of a human being and teleport them to a different place. What you'll get is a particle soup with similar properties, which doesn't really help. For teleportation to work, one side has to know the exact attributes of the particles in a person, and their relation to one another, transmit the information to the receiver, and then have the receiver construct a new human. I guess it is similar to the method used in Star Trek.

But the computing power and general level of technology required to do this is unfathomable. It won't happen in the next few decades, and I doubt it happens in the next few centuries. By the time humanity is able to teleport matter across such distances on such scales, off-Earth expansion will have become trivial eons before.

Hmm, interesting. So any materials would probably need to be shipped to such stations instead of teleported. Communication would be feasible but not transportation of goods and personnel.
I knew you'd know more about this.

Not faster than light communication. Information has to be transmitted at the speed of light. However, I have read some speculative papers that try to propose ways of "guessing" information in entangled particles using probability machines and predictive algorithms. It is an interesting idea, but I have serious doubts about their feasibility.

I was thinking speed of light.

As for the future and what it holds I guess we will just have to see what we make of it.

Well, we're communicating at the speed of light right now. So I accept the reality of that.

I think it's possible is asteroid mining is as easy and as profitable as Siro is making it out to be that it will be something tackled by private enterprise, so it may not end up being a matter of divided focus and funding. It could still be possible for government run space agencies to send people to Mars.

Siro, would it change your mind if there was a better than not chance of finding evidence of life on Mars and human explorers greatly improved the chances of finding the best evidence? I think finding evidence of extraterrestrial life would be absolutely massive as far as getting the gears turning in the direction of space exploration in many forms.

Until I see a private company take on either of these projects I'm going to assume it's going to require government involvement to make it happen. It would not surprise me if private enterprise partners with the government, and even eventually takes over the project, but it makes no logical sense to me to pursue a second project that has the probems Siro has outlined. I have not done research outside of this thread on either of the projects, though, so I'm relying on Siro's information to form my opinion at this point. If it turns out that the what he is saying is substantially wrong my opinion may change.

Private companies are now moving into space flight and space tech. In time who knows what will happen. Either way I think America needs a push.

Come one Russia and China! Reignite the space race. Americans love to compete, it's in our blood.

What scientists refer to as "quantum teleportation" is light years away from what lay people think of as teleportation. Don't hold your breath.

Guess Siro beat me to it, LOL. Nice job.

I will take your and Siro's word on it lol.
