Reply to comment by strvgglecity in A wormhole that connects two points in space where the strength of gravity is different would let you violate the 2nd law of thermodynamics. by chancellortobyiii

Then pass multiple stars worth of mass through the wormhole that connects places with different gravitational potential.

I’m going off my college physics and astronomy classes here. And I’m old. So things may have changed, and I may have forgotten things. But if I remember correctly, quantum foam, or the basic level of quanta is roiling with “wormholes” that appear and disappear like bubbles in a soda. My professor said it would be cheaper (from an energy consumption perspective) to catch one and manipulate it than it would be to create one fresh. Even then, the targeting, tracking, then trapping 1 end (Nevermind both ends), holding on to it, expanding the orifice to a useable size and then stabilizing it. Well, it isn’t just a matter of available energy. You would also need energy to produce the needed exotic particles and anti matter on an ongoing basis needed to feed and control this one end of the wormhole. I think we, as a class, calculated a guesstimation that you would need millions’s of Dyson spheres (around a red dwarf, meaning 100% of a star’s output) worth of energy just to produce exotic particles (that we haven’t discovered yet) to use to manipulate and stabilize the entry. Nevermind feeding it enough exotic particles and antimatter to make it large enough to use, or build a tunnel of safe passage for travelers. And you would still have the other end whipping around the quanta trying to evaporate. But it can’t because your dumping all this energy into it. so it’s constantly shedding all the energy, exotic particles, and antimatter that you are pouring into it, out the other end. This would require more energy at an ever increasing pace. There would be no way to recover all that energy as we understand physics today. I also remember that the interior of a wormhole would be lethal to human life as well? Again, I’m old and so is my information. A good book about this, even though it may be a bit dated now, is “Blackholes and Timewarps” by Kip Thorne. It was a great read.

Ok but to be clear, how would you know how much energy you need to produce exotic particles when you haven’t discovered them yet?

I feel like any calculation done with that assumption is pointless. For all we know it might be an easily mass-producible polymer that we haven’t discovered yet.

Depends on the definition of exotic particle, we have discovered some in recent particle accelerators experiments (I think they called them tetraquarks or pentaquarks). I don't know if it's as easy as simply discovering a way to mass produce them because of their properties, the standard model predicts they are only formed in the most extreme circumstances and for an extremely short duration.

I'm no expert but I do read about physics for entertainment

I understand what you are saying

But how are you supposed to know how much energy you need to make something without knowing what you are making?

Xelephis t1_j4820gn wrote

I think the standard model can predict they exist and we just smash particles together til we find out the energy when they are formed. It's not elegant but it's science lol.

Yes we know they exist, but again, how do you know those particles sustain a wormhole? There’s nothing suggesting that.

I mean I don't even believe in worm holes as a real object in our universe I was just advocating for exotic particles. I have not read the latest theoretical worm holes that "could" exist.

Sorry if I was misleading in that manner, you are correct nothing suggests that

Pretty sure Hawkins is the expert on workholes and said something down the lines of they can exist but would collapse as soon as any amount of matter (or energy?) attempted to pass through them?
