Physicists Release Step-by-Step Instructions For Building a Wormhole (space.com) 73

Posted by EditorDavid from the across-the-universe dept.
schwit1 quotes Space.com: A recent paper, published to the preprint journal arXiv on July 29, has found a way to build an almost-steady wormhole, one that does collapse but slowly enough to send messages — and potentially even things — down it before it tears itself apart. All you need are a couple of black holes and a few infinitely long cosmic strings.

      OK, my USB cable box has the infinitely long cosmic strings.

      And another box has PCMCIA Ethernet, IBM Token Ring and ISDN cards in it. So they could classify as Black Holes.

      Years ago I worked in a research lab. The guy who ran the lab had, in his younger days, had a rubber stamp made with the phrase “This is not science” which he purportedly would use on particularly bad papers which had been sent to him for peer review.

    • This is falsifiable, for example we could find that gravity does not work according to their assumptions. They do assume the existence of substances that don't actually exist, but that is still falsifiable. For example, you could do some math and find that even if they did have unobtanium, they still couldn't build a wormhole. Unfalsifiable would be if they said, "you are really just my dream." there is literally no way to test that because even if you devised a test that worked, the counterargument is "I d

      Science is falsifiable, i.e., it can be proven wrong given the case.

      Technically this is science because, at least in theory, it can be proven wrong even though we do not yet have the technology to check the prediction. This is often the case: it took over 100 years to develop the technology to show that gravitational waves exist after Einstein predicted them.

      However, it does seem somewhat useless since it first requires an infinite cosmic string. So it seems to have merely replaced one almost-impossibility with another. The only way it might turn out to be useful is if it inspires someone else to find a more probable/easier to create situation.

      • However, it does seem somewhat useless since it first requires an infinite cosmic string.

        That's only to make the whole system work as described.

        In order to prove it could work, all you need is a medium length cosmic string long enough to dip into the black hole. Then you can monitor if the charge of the black hole changes as predicted, possibly also monitor the vibration of the cosmic string is as described.

        So it might only be thousand years or so before we can validate it...

          Well I suppose one could prove the concept has some merit using "just" a really long string. But if it's physically impossible to use an infinite string, then ultimately it's not fully testable.

          Can somebody think of a scenario where one could obtain or tame in existing infinite string? Assuming one could tap the energy

          • Can somebody think of a scenario where one could obtain or tame in existing infinite string?

            Yes, it's quite simple really. All you need to do is create your own universe and, if they exist at all, they should form naturally.

      • This is often the case: it took over 100 years to develop the technology to show that gravitational waves exist after Einstein predicted them.

        60 to 70 years actually.

        Einstein's GR was published in various papers up to about 1915.

        In about 1975 astronomers discovered a pair of mutually orbiting neutron stars (one a pulsar), and careful timing of their individual rotations and mutual orbits showed by 1982 or so that the system was losing energy which wasn't coming out as light (we'd have seen it), magnetism

        • True, but that is indirect evidence and the Nobel was not awarded for discovering gravitational waves, only "for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation.". Seeing behaviour that is consistent with a phenomenon is an important discovery but it is still not the same as actually discovering the phenomenon itself.

          We see lots of evidence consistent with Dark Matter out in the universe but nobody would claim that we have discovered Da

    • All they need now is to get the Flogrondifier in phase with the Kersitritron, and adjust the plasma ionic quantum frequency to 23.340Thz, and the azimuth of the particle nuclear beam to 40 degrees and tie it into the Lazerphasetransmogrifier, and they can do what they need to do easy peasy!

        Every respectable physicist knows this!

    • ... you couldn't build the box for "Schrödingers cat" either, yet it was a contribution to science, since it provoked people to think. Another great example is the EPR paradox, that started as an attempt to poke holes into quantum mechanics. It led to the formulation of the Bell inequality which was then experimentally tested.

      It's completely ok and scientific to "play around" with physical theories and see what comes out of it. If nothing else it might reveal a weakness/gap/inconsistency in the theory.

      yes, the extent of the whole universe (including what is outside observable) might be infinite with infinite amount of matter. it's an open question. the "big bang" doesn't mean everything expanded from 1 point, that idea is long dead in cosmology, the "big bang" is a moment before which known physics doesn't apply.

      • For certain values of "infinite".

        • space and matter without finite limit in all directions beyond the observable universe is what cosmologists are wondering and can't answer. We already know the present visible universe is less than one part in 10 to the 23rd of what existed earlier.

        The universe itself, perhaps?

        It's only been expanding for a finite amount of time, and as such is still finite in size (approx 55billion light years if I recall correctly).

        Which is vastly different from being infinite.

        And I realize that I am only talking about the observable universe here, but to talk about things outside of the observable universe as if they could ever influence anything inside of it is pointless.

    All you need are a couple of black holes and a few infinitely long cosmic strings.

    There was a Saturday morning kid show called Wonderbug. Whenever they were in a jam, one dude would say something like, "I have a plan, but it requires a spring, 2 horses, the Osmonds, and 30 lbs of dental floss."

  • Experimentation has shown the longest time a wormhole has remained stable was 38 minutes. There's been some dispute on this as wormholes were timed to be stable longer but this was only in the presence of strong gravitational forces in which time dilation effects likely extended this time to an observer outside of this field.

    While matter may pass in only one direction there is the possibility of two way communications by means of electromagnetic forces influencing the event horizon and propagating through the wormhole with a delay so short as to allow for casual conversation by radio.

    The event horizon has been able to be contained with a ring like device made of a super conducting and highly dense element.

  • I am sure unicorn horn would work just as good as infinitely long cosmic strings.

    • just like the Alcubierre drive with its "high negative density exotic matter" that so many go gaga over, no it can't be built with anything that actually exists.

      Zero evidence for strings, after jacking around for decades the string theorists have nothing. They've essentially proven the well known fact that an infinite number of functions can be used to go through any finite set of points on a graph. Nothing useful, nothing testable.
