Perhaps a useful resource for further developing wormholes

13 Dec 2016 01:33

Hello,

I stumbled upon a Github project that implements Interstellar-style wormholes in WebGL, with some demos: https://sirxemic.github.io/wormhole/ and https://sirxemic.github.io/Interstellar/

Since wormholes are still experimental, perhaps the developers can use these as examples and/or sources of inspiration?

EDIT: I particularly like the second link, where the wormhole is like a "spherical portal", that is, without a "tunnel". You can move sideways, be partially in one place, and partially in another.

Wow! I've seen the renditions of wormholes based on the appropriate general relativistic formulas, but never ones you could explore like that.  Those are really cool, thanks for sharing them!

The wormholes in SpaceEngine are fairly accurate, but the hard part is programming the link.

Wait, where are the wormholes?

You can make a wormhole from a black hole by simply editing its type from X to Z in the editor (shift-F2).
Not implemented yet, though.

And that method will never work, even when bridging is possible.  Wormholes were added for setting up presentations and for mod systems.

maybe the supposed dark matter filaments are possible intergalactic highways, stabilizing wormhole, einstein rosenberg, bridges. someone must have posted that somewhere. i remember seeing a part of a semi educational video that mentioned how something like filaments could, in theory, have been created during the big bang and could be natural wormhole routes.

so if the simulator included known and procedural galaxy filaments, then maybe wormholes could be made along them somehow, but realistically, i don't know how to survive it, if the gravitational forces would crush and rip people, unless a shield of dark energy or something could nullify the effects on the traveler like a bubble shield and use the transmuted energy of the gravity from the wormhole as a power source to do it.

No, this confuses dark matter with some hypothetical (probably impossible) form of exotic matter necessary to keep a wormhole open.  In terms of gravitational effects dark matter is just like regular matter and can't do that.  The filaments also did not form in the Big Bang, but later as a consequence of denser than average regions collapsing gravitationally to produce the cosmic web.

is that the negative mass or something else. also, how does dark energy compare to that idea. all i could get so far is that is pushes things apart.

if it is dense, how does it collapse?

thanks

Those actually remind me of the one I made a few months ago. Great minds think alike I guess ^^;

P.S.: @darkenergywarpdrive - keep in mind that this is on a cosmic scale. A "dense" region is denser than its surroundings, meaning it contains more matter, but that doesn't mean it's rigid or under any significant pressure - it's still very much outer space. Since matter attracts other matter gravitationally, anywhere matter is built up it will draw itself closer together. Over time any slightly denser region of space tends to contract into a clump, or if matter is in between two or more clumps, it will collect into a filament or sheet. This will continue until something happens to create outward pressure, such as a star or quasar forming - hence today we find galaxies in clusters, filaments, and sheets.

wow these are some nice wormholes, thanks for sharing!

I wouldn't say no to stable wormholes, especially if sterile neutrinos (which may be able to travel through time since they do not respond to any force but gravity) are found one day.
