At the least light should escape a wormhole, and we should "see" what is on the other side. Otherwise I'm not sure how it'd be possible to detect any difference

At the least light should escape a wormhole, and we should "see" what is on the other side. Otherwise I'm not sure how it'd be possible to detect any difference between a wormhole and a blackhole.
- gizmo686 6y agoThats the question. Even if wormholes exist, the Universe is under no obligation to make them observable to us. If they are always on the other side of a black hole event horizon, then there would be no way for us to detect them, even in principle.
- Johnjonjoan 6y agoWould we not be able to infer their existence by finding a white hole? I do see how calling that a detection could be a stretch.
- nine_k 6y agoActually, GR describes white holes, along with black holes, but no ideas how a white hole would form in the real universe apparently exist.

- maxcan 6y agoIt is true no physical law obligates the universe to make them observable to us. But, this is the same universe that gave rise to Star Trek, Firefly, and especially The Expanse making so many of us dream of interstellar travel. So, I’d say ethically it’s pretty damn obligated to make them observable :) /s (Sort of.. not really)
- unkulunkulu 6y agoLife imitates art, the universe will surely give :)
- iso947 6y agoFirefly is all STL. It’s ambiguous how they got to the system they now occupy.
- Filligree 6y agoWait, really? I haven't watched the show, but aren't there like six different habitable planets involved? You can't have that all in a single star system.
- AnIdiotOnTheNet 6y agoThey kinda try to patch it up in the movie "Serenity". Supposedly the whole show takes place in a gigantic star system full of giants with dozens of moons amounting to hundreds of worlds. They also have some form of terraforming tech to make inhospitable worlds habitable. Frankly I find that whole set up only slightly more plausible than some kind of FTL, especially since they also have gravity manipulation tech already.
- iso947 6y agoMore. All geo engineered. Ambiguous how humanity got to the system though. That said recent talks about habitable zone around a black hole made me wonder if that would work.
- maxcan 6y agoI honestly did not remember that. Good point.
- int_19h 6y agoIIRC it's spelled out somewhere that the colonization fleet was generation ships.
- raducu 6y agoThis is the same universe that gave rise to the Tide Pod challenge. Perhaps in the far future there will be a Find a wormhole challenge where future human teenagers will dive their spaceships into a blackhole they think is in fact the entrance to a wormhoe and scream YOLO just before entering the event horizon.

- de_watcher 6y agoIf they're not observable then they're all unidirectional from here to somewhere over there (or from there to here but there is nothing over there, not even vacuum fluctuations).
- nine_k 6y agoIf they are undetectable, that is, never ever influence anything in the observable universe, the Occam razor instantly shaves them off.
