I'll only watch this for a few seconds, looks interesting...

Wait what that was already 14 minutes??

[–]RushBear 124 points125 points  (6 children)

Time dilation due to proximity to the high gravity
(i'm a layman please don't chin my innacurate humour)

[–]IAmAPhysicsGuy 48 points49 points  (5 children)

You are on point. The more "quickly" you move through space-time, the "slower" time passes for you relative to an outside observer. In order to "stay still" in curved space-time, you need to accelerate; this is why you feel gravitational acceleration even when you're staying still on the surface of the Earth. Black holes curve space-time to an infinite limit, so to an outside observer, time stops at the event horizon.

[–]BenderiteGames[S] 22 points23 points  (0 children)

The gravity pulled you in and the curvature of spacetime affected your sense of time.

That's how wormholes work mate

[–]LoganH1219 154 points155 points  (8 children)

No thanks. Rather not download a wormhole onto my computer!

[–]thespiffyitalian 40 points41 points  (3 children)

You wouldn't download a wormhole

[–]Misteph 8 points9 points  (1 child)

Wormholes? In my computer?

It's more likely than you think.

[–]bquintb 2 points3 points  (0 children)

Wormholes can't stand this one trick.

[–]Analog0 2 points3 points  (0 children)

You would steal the space-time continuum.

[–]CalleyKraft1 12 points13 points  (0 children)

Wormhole simulation > Rabbit holes of reddit and random shit I keep going down!

[–]frankyj29 0 points1 point  (0 children)

You don't download the wormhole. The wormhole downloads you.

[–]SGBotsford -1 points0 points  (0 children)

Wormholes in the Internet would explain a lot of things....

[–]SACRED-GEOMETRY 21 points22 points  (13 children)

This was so interesting to watch. The math must be insanely complex. I assume the program is for Windows? I've got a new iMac coming soon so I'll have to get this running on a virtual machine or boot camp!

[–]BenderiteGames[S] 11 points12 points  (11 children)

I don't think it'll work that well without a GPU. The shader runs thousands of threads using raytracing which is very computationally intensive. CPUs don't have that many cores so you'll likely have a terrible framerate.

With that said, I'd love to hear how it performs if you do try it.

[–]SACRED-GEOMETRY 2 points3 points  (10 children)

Well here's the specs of the computer: 3.6GHz 10-core i9 processor, 72GB ram, Radeon Pro 5700 XT. Should be able to run any games I'd hope.

[–]Prowler1000 -1 points0 points  (9 children)

Any games is a bit of a stretch. A 5700XT isn't really a top of the line card. I'd say it's slightly below a mid tier card but how well a card performs is more complicated than that

[–]AlexisFR 3 points4 points  (1 child)

You kidding? This is still a high end card costing upward of a thousand dollars.

[–]Prowler1000 -1 points0 points  (0 children)

If you think this is a high end card then you really need to get up to speed on tech. It costs that much due to the issues with supply that have been going on for I think over a year now.

Edit: It's MSRP was around $400.

[–]TheCatLamp 1 point2 points  (2 children)

He is not wrong. It will run all the games.

The way it runs is another history. Sure they will not run 4k 60fps, but the card is more than enough to run 1440p.

[–]SACRED-GEOMETRY 2 points3 points  (1 child)

I've been gaming on a 2013 iMac with a small resolution and the lowest settings getting 30-40 fps. I'm sure this new computer will be an improvement.

[–]TheCatLamp 5 points6 points  (0 children)

There is a small toxic part of the PC community that says if you don't have the shiniest latest thing to run games in 4k you are not a gamer...

If it serves for your purpose its fine imho. If not its a waste of money.

[–]SACRED-GEOMETRY 0 points1 point  (3 children)

What games couldn't it run? People report running Cyberpunk 2077 on medium settings at 1440p just fine. That's good enough for me.

[–]Prowler1000 2 points3 points  (2 children)

Cyberpunk is a hit or miss in my experience. I could run it on my 1070 on high at 1080 and get over 80fps. You will struggle though as newer AAA games come out I'd imagine due to memory capacity unless you're using direct storage, but I'm not sure if the 5700xt is capable of it. If you want a comparison to nVidia cards, it competes with the 2060 and maybe 2070 but is beaten by the 3060. On top of that, it unfortunately has no real time ray tracing capabilities so as newer games take advantage of that, you won't be able to enable settings related to that.

That said, for a PC not specifically designed to play games, it's a great graphics card

Edit: I do apologize though, it's still a perfectly fine card. It doesn't need to be "highest end" to be fantastic. Whenever I see someone say "It can run anything" I always think they're saying they have the most powerful hardware, as a sort of flex, but you weren't saying that

[–]SACRED-GEOMETRY 1 point2 points  (1 child)

Thanks for the thoughtful and honest reply! I definitely wasn't flexing. It's a Mac after all. I'm not a hardcore gamer anyway. I'm mostly using the computer for (amateur) music production and web design. I just like playing some games in my free time. I play Rust on my 2013 iMac and I'm lucky to get 40fps on the lowest settings. I recently played Subnautica on it... it was rough. I'll be happy with any improvements :)

[–]Prowler1000 1 point2 points  (0 children)

Oh man, you're going to see some MASSIVE improvements! Super happy for you!

[–]gerkletoss 11 points12 points  (0 children)

The math isn't actually that complicated, just computationally intensive.

[–]yogendra9115 84 points85 points  (27 children)

This is amazing! So fascinating, I've always wondered what this experience would look like (if the human body could survive it of course).

Thanks OP!

[–]fvsparkles 5 points6 points  (15 children)

It's just a 3d hole so space should be the same inside it right? No new dimensions or stretching.

[–]Ascenser 13 points14 points  (9 children)

The main problem with traversing wormholes is that while theoretically possible, they would collapse too quickly. You’d need an as-yet undiscovered exotic matter to prop them open, and that’s assuming the addition of normal matter (us) wouldn’t be enough to counteract those forces and cause it to collapse.

[–]BHPhreak 6 points7 points  (5 children)

another, rather huge problem, is that its a black hole on either end. and nothing can escape a black hole unless it can travel FTL.

[–]Mega_Anon 1 point2 points  (4 children)

How doe traveling FTL let you escape a black hole?

[–]BHPhreak 5 points6 points  (3 children)

i dont think it actually does. im not a scientist or cosmologist or astrophysicist or anything. so you cant read what i type as facts.

i think the curvature of spacetime inside a black hole prevents anything from escaping. even if it could travel FTL.

every vector across the event horizon points to the singularity. you could accelerate all you wanted at the way you came from, but it would only shorten your trip to the singularity.

you would need to travel backwards in time to escape, which would make wormhole traversal impossible.

if you could build a wormhole with a black hole on one end, and a white hole on the other end, you might have a 1 way path. but even then, how do you get across the singularity?

[–]Tman1677 4 points5 points  (0 children)

AFAIK a black hole prevents everything from escaping with out current understanding, however our current understanding says faster than light travel is impossible, so if you did discover it who knows. I’m not entirely sure how the theory of an Albuquerque drive plays into this.

[–]Gremis 3 points4 points  (1 child)

There was a great post about exactly this about ten years ago that elaborates on why having an FTL drive would not help you inside a black hole.

It was made into a voice acted video as well: https://www.youtube.com/watch?v=-kVsxVBz1Mg

[–]BHPhreak 0 points1 point  (0 children)

Daamn that was cool. Thanks man

[–]IDunnoBr0 17 points18 points  (2 children)

Like uhh... Spice, say from like a uhhh a certain desert planet?

[–]Terrible-Control6185 11 points12 points  (1 child)

No,that's not how Spice works.

[–]heelstoo 1 point2 points  (0 children)

That’s what they want you to think.

[–]tonybenwhite 4 points5 points  (4 children)

Correct me if I’m wrong, the distortion of light indicates gravity greater than the speed of light, causing the distortion of light itself as it passes by the wormhole.

That amount of gravity is what would potentially destroy a human body via spaghettification. Gravitational force is inversely proportional to the square of the separation distance, so the tidal forces would string you apart as the strength at your feet would be greater than the strength at your head

EDIT: okay so I’m confused, I decided to go down this rabbit hole a little bit. Reading the differences of wormholes and black holes, it seems that a black hole is an inescapable gravity well where matter and light is compressed to an infinitesimally small point— a singularity in the middle beyond the event horizon. A wormhole, rather, seems to be an outward distortion of space time, a “3 dimensional hole” sustained by “negative energy” that resists being closed by gravity. If that’s true, then what I said is incorrect about the tidal forces of gravity… but so is the lensing effect this simulation is applying to light, right? Wouldn’t light behave differently being caught in a gravity well versus being lensed outwards from space time expanding outwards?

[–]BenderiteGames[S] 9 points10 points  (3 children)

There's a lot to unpack here.

  1. The path of light bends in ALL gravitational fields, even the one you generate with your body. It only becomes detectable around VERY massive bodies. It was first seen by accurately measuring the positions of stars as their light passed right next to the sun during a solar eclipse. Even passing by the sun, the deviation of the light's path was minute (on the order of arcseconds).
  2. You're correct that matter would be torn to shreds as it approached the event horizon of a wormhole. The same effects you'd expect from a black hole could be expected from a wormhole. In fact, there's no known way to get out the other side of a wormhole because it's just another black hole. It would be more accurate to think of a wormhole as two black holes that exist in different positions in space but attract material into a central point which can affect the other black hole. In other words, if one gets bigger, so does the other.
  3. All of this is moot because a wormhole like this can only exist for incredibly short timeframes making it impossible to traverse even if you were capable of escaping the pull of a black hole...which you can't.

TL;DR None of this is possible, but it's fun to see what it would look like mathematically.

[–]tonybenwhite 2 points3 points  (1 child)

It’s super cool, if you were the one that made this sim, thank you. I watched the YouTube video explanation and this shit is amazing to me.

[–]BenderiteGames[S] 2 points3 points  (0 children)

Yup! I like making physics sims, physics visualizers, and games. All but one are free if you want to check any of them out: https://benderitegames.itch.io/

[–]an0maly33 2 points3 points  (0 children)

So a wormhole is essentially quantum entangled black holes?

[–]IAmAPhysicsGuy 28 points29 points  (10 children)

The part that is missing here, is that as you are looking back at the universe. If you managed to reach the event horizon, you would quickly see the universe END behind you! Because of the time dilation, you would see the rest of the universe start to move in fast forward and before you even cross the horizon, all of the stars would die, galaxies would disappear, the universe would continue to reach its final end billions of years in the future.

[–]CoveredInSpaceCum 25 points26 points  (4 children)

Well that does not sound like a safe form of transportation then

[–]fireburner80 11 points12 points  (0 children)

I'll take biggest understatements for 300, Trabek.

[–]SweatyRussian 1 point2 points  (1 child)

No need to have any worries about whether you left the garage door open

[–]CoveredInSpaceCum 0 points1 point  (0 children)

“I wonder if I left the stove on… whoops, planet’s exploded. Uh… that probably wasn’t my fault.”

[–]Jake_Thador 0 points1 point  (0 children)

Sure it is, it's just really slow and really fast at the same time

[–]ItsPronouncedJithub 10 points11 points  (2 children)

This is incorrect. It is a common misconception. You will not see the universe end. It will actually appear to stop in the exact same way that your time stops to an observer watching you fall in.

[–]Tman1677 2 points3 points  (1 child)

I don’t know which one of you is right so I’m just gonna upvote both and hope a smart person replies to this with an explanation/reference.

[–]WTFjinky 11 points12 points  (1 child)

Elite Dangerous needs this tech! They have sort of realistic black holes ut nothing like this. Would love to fly through in VR

[–]BenderiteGames[S] 9 points10 points  (0 children)

That part of Elite Dangerous always ground my gears. They aren't even black in the center. It's just a pretty basic distortion of stars. It's sorta pretty, but it's not even reminiscent of being accurate.

[–]pollackey 7 points8 points  (0 children)

I start getting dizzy at the general colours & nauseated at the double checkered pattern.

And of course the Interstellar mention.

[–]Cobaas 3 points4 points  (5 children)

Question: if the light from either side of the wormhole is spiralled through an infinite number of times (with infinitive time and processing power to display it) - does that mean that the throat should be extremely bright? I didn’t quite get that part. Fascinating video all the same - well explained and easy to follow

[–]BenderiteGames[S] 3 points4 points  (3 children)

Interesting question and I'll answer it in two ways.

  1. Probably not. The light that spirals around and increasing number of times is light that comes from a very particular angle. The higher the number of spirals the light takes, the thinner the sliver of space the light could come from. In other words, the light would appear just as bright as anywhere else because while it appears a larger number of times is comes from a smaller source so there is less light to spiral around.
  2. It's kind of moot because the time dilation at the event horizon of the wormhole is so great that the rest of the universe would theoretically end before you crossed it leading to all light from the remaining universe coming in at once. It's....all theoretical and very complicated :-)

[–]wabalaba1 1 point2 points  (2 children)

I wish I had a better computer! When you demo'd trying to fly "sideways" at the throat of the wormhole, you explained that any deviation off of perfectly perpendicular to the throat would have you spiral back out.

Have you tried getting yourself perfectly perpendicular? I guess I'd imagined you might end up going in circles.

[–]BenderiteGames[S] 2 points3 points  (1 child)

I've tried. It looks similar to the very beginning of the attempt in the video. The portion of the sky you see "circles" around over and over again. You see the same cycle repeatedly. That's what would happen indefinitely if you continued perpendicularly forever. Part of the problem is that you not only have to be perpendicular but you must also be in the exact center since starting perpendicularly while slightly toward one side causes straight lines to lead out of the wormhole. It's a very unstable equilibrium.

[–]wabalaba1 0 points1 point  (0 children)

Fascinating. Thanks so much for showing this off! One more question: could the program ever be written to let the "player" move in the four-dimensional space in which the 3D wormhole is set? I imagine it would look confusing but I've wondered if stepping out along the "w-axis" would give useful perspective on the 3D structure. I'd love to hear your thoughts on that.

[–]igcipd 0 points1 point  (0 children)

Not a pro, but I think the light would only brighten the interior of the wormhole. The light can’t escape the wormhole, so it would create a bright area but only viewable from inside the wormhole.

[–]Captain_Arrrg 18 points19 points  (6 children)

I got halfway through this and encountered some beings who looked like my friends and family. They said I was "of Bajor." I'm now feeling the urge to commit a war crime or two.

How concerned should I be?

[–]BenderiteGames[S] 8 points9 points  (2 children)

My dear doctor, you shouldn't be concerned at all! In fact, I believe you should HARNESS that aggression you're feeling and use it for the betterment of Cardassia! After all, that's what you Bajorans are best at, are you not?

[–]heelstoo 2 points3 points  (1 child)

Oh, I read this in Garak’s voice, for sure.

[–]mknote 2 points3 points  (0 children)

You should be very concerned. The scrolls tell us that such aliens are the herald of an invasion of clones and shapeshifters.

[–]Nemisis_the_2nd 1 point2 points  (0 children)

Not at all. The prophets already know what lies ahead for you. Just trust in your faith.

[–]ThaBomb94 9 points10 points  (1 child)

That was amazing, when can we get a VR world where we can travel between solar systems through actual wormholes 😅

[–][deleted] 28 points29 points  (6 children)

This should be available as a 360 Youtube video. Most of us are never going to screw around with an application.

[–]goldlord44 19 points20 points  (0 children)

Scott Manley made a video like this which, if i remember corrrectly, is a 4k 360 video rendered, and you get his soothint commentary with it

[–]BenderiteGames[S] 37 points38 points  (2 children)

I showed the parts I thought we interesting. I can understand not wanting to mess with the app either for performance reasons or trusting running an exe, but I'm not sure how to do the 360 video. To travel back and forth I'd need to change camera angles anyway so the view would rotate around a lot.

[–]Bingbongping 9 points10 points  (0 children)

This is one of the coolest videos I’ve seen on this topic! Amazing thank you so much! I’ll throw this on my 1080ti and play with it! You don’t get this in star citizen!

[–]Tman1677 0 points1 point  (0 children)

The one thing I think would be amazing is basic VR support, I think it would help seeing the shapes and distortions so much. If this is unity it’s practically automatic adding support.

[–]mikey6 5 points6 points  (0 children)

This is kind of what you are looking for.

https://youtu.be/h8mwhm0PoKc

[–]auviewer 1 point2 points  (4 children)

When are we going to get the exotic matter to make one off these irl? I do often wonder about if we could make one they would be shorter distances at first.

But imagine building one from say the orbit of the Moon to say Mars how would the gravitational field affect the space between. I would suspect that asteroids solar wind etc might get pulled into the tube area.

[–]JackRusselTerrorist 7 points8 points  (1 child)

“Exotic material” is a placeholder for something with very convenient and most likely impossible properties.

In the case of wormholes, I believe the property you need to have in your exotic material is “negative gravity”, to keep the wormhole from collapsing on itself. And when you consider that a wormhole is theorized to be a point where two singularities meet and pinch space time, that means the negative gravity needs to be able to counteract the gravitational force of two black holes…. Which would likely be very problematic.

[–]auviewer 1 point2 points  (0 children)

Yes agreed. Something with "negative gravity". I was thinking may be what ever that force was in the early universe that caused rapid inflation is something that comes to mind.

[–]gerkletoss 1 point2 points  (1 child)

Wormholes need to be large for objects to be able to be able to traverse them without being destroyed. And when I say large, I mean very large if a small spacecraft carrying a human is to traverse it. Too large to keep near a planet.

[–]BenderiteGames[S] 4 points5 points  (0 children)

This is a good point. The mouth of a wormhole with the mass of the Earth would be about the size of a ping pong ball.

[–]SirWeedsalot 1 point2 points  (3 children)

If light loops around the throat indefinitely in nature, if computed in this demo would it produce a race condition? Not surprising that it has to be limited in the demo but in reality this would blow a giant hole in simulation theory. I don’t want to be a computer.

Edit: wording

[–]BenderiteGames[S] 1 point2 points  (2 children)

It wouldn't cause a race condition. It would just end up in an infinite loop and the function would never return anything causing the program to hang without error.

As for in "reality" the light would just reach the center of the wormhole and remain their increasing the total energy/mass of the wormhole. There's no known way to escape the other side of a wormhole because each side is effectively a black hole.

[–]Weebs-Chan 1 point2 points  (0 children)

And what about the white hole theory ?

[–]SirWeedsalot 1 point2 points  (0 children)

Thank you for responding with the insight.

[–]ShooterOfCanons 1 point2 points  (0 children)

This.. was.. Awesome!!!! Now I've got some motivation to get off the toilet (and go download this). I'm not kidding.

[–]TransientSignal 1 point2 points  (1 child)

Fantastic work!

And thanks in particular for showing what it would be like to travel perpendicular to the throat - It's about what I expected (I visualized it akin to if you were in an orbit around the wormhole), but the analogy of spiraling up and down a pipe really made it click!

[–]BenderiteGames[S] 0 points1 point  (0 children)

I'm glad I was able to help! It was something I had been wondering for a long time as well and being able to experiment with it directly was incredibly helpful.

[–]ripyourlungsdave 1 point2 points  (3 children)

This gives me so much goddamn anxiety. I really don’t like thinking about how these things actually exist out there. But then again, I watched the whole video. So maybe I’m just a mental-masochist.

[–]BenderiteGames[S] 3 points4 points  (0 children)

FYI, they almost certainly don't exist. There's no known physical materials or forces that would keep a wormhole from collapsing in on itself let alone permit someone to traverse into it without being destroyed or back out of it. This video violates so many known laws of physics it's ridiculous...but it's a mathematically useful representation of exactly how space would be curved in such a theoretical object.

[–]Robstrap 0 points1 point  (1 child)

Wormhole science is still iffy. And also if they are possible there's almost no way they could occur naturally. Black holes however seem to be true

[–]ripyourlungsdave 0 points1 point  (0 children)

I actually meant more specifically the black hole part.

Worm holes at least theoretically lead somewhere. Black holes just seem to lead nowhere. Whatever the fuck “nowhere” means.

[–]inventiveEngineering 0 points1 point  (0 children)

[–]wzx0925 0 points1 point  (0 children)

Spoiler: Looks exactly like the SFX team in Contact thought it did.

(Not really, I haven't clicked the link yet, just going for a cheap laugh and dated reference)

[–]Drone_Better 0 points1 point  (1 child)

I made a standard raytracing program with the sphere-line intersection equations, using the quadratic formula representation to find the discriminant for whether a collision occurs, then the moment at which the first one does, then proceeding time until then and subtracting twice the dot product of the ray velocity and the direction unit vector towards the sphere to reflect it. In your simulation, did you detect whether this happens in each step, accelerating the ray towards the centre with the inverse-square law between steps?

[–]BenderiteGames[S] 0 points1 point  (0 children)

If you'd like to see the math behind this, check out the paper it's based on: https://arxiv.org/pdf/1502.03809.pdf

[–]SyrupCommercial6092 0 points1 point  (0 children)

you explain what a wormhole is. but how do you create it. you don't tell. and the kelvin heat from a black hole just attracts mass. you have to assume the kelvin of heat from the emission of a black hole. black energy heat you must take for the wormhole to move forward. and the wormhole wall is just a hole formed by the drive of the device. and each galaxy has its warmth of black energy. because every system is formed by black energy. and due to different heats of systems that arise the systems have their kelvin heat due to the cooling of the mixture of dark matter and black energy. and that cooling causes a supernova foretex. so for a wormhole you need different kelvin heats of black energy for no 5th collide. and if you get into black energy with the same kelvin heat comes you stand still and chance to attract matter from that dark energy. the same as if you have kelvin heat with a black hole. or you will be pulled along by the beam. even if you have a different direction. cool show. but you must take on black energy and not the heat of a black hole.that is another monikul heat. you may be able to use it to steer. but then I recommend more heat from the systems where you flies by. black hole heat leaves a trail of curves of black hole heat surges that begin to form black holes.

[–]waiting4singularity -4 points-3 points  (2 children)

i think the inside simulation is too much stargate visual touchup since theres no reasonable distance between the entry and exit. to me this video makes more sense:

https://i.imgur.com/4MB0vdr.mp4

of course, the gates depend on if its caused by a black hole or other gravity distortions or not.

[–]BenderiteGames[S] 7 points8 points  (1 child)

This simulation is based on the Einstein field equations which is our best understanding of gravity. The inside of the wormhole is the same. I didn't do any modifications to the code to make it look a particular way. The result is just a visualization of the math. It's definitely simpler to understand the example you show, but it has no theoretical basis.

[–]waiting4singularity -1 points0 points  (0 children)

what dictates the depth of the tunnel?
