    that's true, but you see what I'm getting at. as long as we don;'t have quantum gravity we can't rule out an inconsistency, and that applies for wormholes as well.

No. It simply means that we do not have a complete understanding. I never claimed complete understanding of wormholes either. But we do know enough to make many statements on feasibility of wormhole travel.
    the difference is heavy nuclei actually exist, whether wormholes exist is questionable.

    You are making a big mistake comparing FTL transport and FTL propagation. Nothing propagates faster than light. In fact, I'll say more. Everything propagates at the speed of light in the 4-space. That's rather fundamental, and we aren't going to break that one. But that doesn't mean you can't have FTL transport. Tunneling is a mode of FTL transport. Information can be conveyed from point A to point B in time less than required for light to cover same distance.

    The important feature of tunneling is that the wave function doesn't simply happen to be on the other side of the barrier. A packet arriving from extended location will be partially transmitted, and the transmitted packet will continue propagating to another extended location. Extended, in this context, meaning that it is far outside of uncertainty of the packet. The time for signal to get from origin to destination, again, far outside of its uncertainty range, can be shorter than time required sans barrier.

    I can write out equations clearly demonstrating this, if you really need it.
    you're right that transport isn't exactly the right word, but you see what I mean, the gap is due to the quantum wave nature, not something we can manipulate.

      Sure we can. We know exactly the conditions when the conventional GR breaks down and quantum gravity is required. You've probably heard of Plank Scale. That's basically it.

      Can't argue with that. And whether or not we'll ever be able to find or manipulate them is an open question. Point is, if a macroscopic wormhole does exist, we can describe it. Because it is just a section of manifold that happens to have peculiar topology. Since no specific topology is assumed in GR, we can say a lot of things about it.

      What General Relativity absolutely does not tell us is how to create/destroy a wormhole, because that requires alteration of space-time topology. This I admit, we know absolutely nothing about, and we cannot make any reasonable prediction on that part. So you'll notice that when wormholes transport is being discussed, I never go into how connection may be established. No way to know how and even if it is possible.
      you're right that transport isn't exactly the right word, but you see what I mean, the gap is due to the quantum wave nature, not something we can manipulate.
      Chemistry is due to the quantum wave nature of electrons. Doesn't mean we can't use it.

      By the way, a photon packet tunneling across gravitational barrier will not be distorted, and transmission ratio will not depend on packet amplitude. Furthermore, if the barrier height is just right, and gravitational noise is minimal, the transmission coefficient can be rather high for rather large distances. So I'm kind of hoping for quantum black holes as potential means of "sub space" communication.

        Honestly, I don't know. Anything can be possible if we put our minds to it.

          In the show or for real?
          In the show: mabey. I bet Carter and Mackay could do it.
          In real life: probly not. You would need naqudah, the quantom compnents and in dept knoloage of the gate's systems and structure.

            In the show yes, the plans for the stargate would be in the Atlantis and maybe Destiny's database's and maybe the database of a seeder ship if the SGU crew ever come across one. Plus they have the toaster gate Orlin built that they probably took to area 51 for study, along with the list of parts that he ordered online using Sam's credit card. X'D

            As far as us in rl, maybe one day if we ever break our dependency on fossil fuels.

              Orlin also created an emerald out of nowhere, so he could have done some fancy magic with the toaster to make it a gate. Good luck Area 51.

              I don't see what the use of fossil fuels has to do with interstellar travel using artificial and easily-creatable wormholes.

                well as fast as our tech grows we will have wormhole in the next 180 years .

                    Sorry, you're right. Nevertheless, it shows he could do some crazy things we couldn't possibly replicate. Anyone know how to turn a microwave into an Emerald?

                      Actually emeralds are very easy to make for mere humans - piece of cake for an ancient.

                        How does one take a microwave and turn it into an emerald?
                        It's as likely as us building a Stargate with current technology.

                            Well it's gonna need something to power it up, especially 8th and 9th chevrons. lol

                              Emeralds are tricky, but as with most artificial crystals, they are grown at very high temperatures, so a microwave makes sense. Stock material for a Emerald is a bit difficult to come by. You need a superheated solution containing beryllium, aluminum, and silica. A ruby or sapphire would be a lot easier to come up with. So I'm guessing Orlin was showing off.

                                and look at the size of that Emerald i am thinking why didn't he made a diamond and Sam would be rich by selling it on Ebay .
