I still haven't been able to entirely wrap my head around the concept of "space-time fabric". I do understand that massive bodies bend it, but I can't stop thinking how other celestial bodies, ( planets, stars, etc), are "above" and " below" us, yet remaining in the same plane of the fabric of spacetime. It is an simplification of something more complicated, isn't it.?
Exactly.. and if the other planets and stars exist the same fabric of space time, then if a black hole or a wormhole twists the fabric then it should affect the stars and the planets
Space time is not 2D, it’s 3D (or technically 4D but that does not help us here) it’s everywhere. Think of a beaker of water and a rock. The water is space time and the rock is a planet. You drop the rock into the water and it displaces the water. This is the same concept. Mass takes up area. It takes up space if you will.
Why are they called wormholes? Is there a theoretical giant worm digging its way through space, devouring planets, stars and nebula and pooping out dark matter? Is that the way the universe ends? Giant galactic space worms?

Thank you!! Ive been saying for years that wormholes are an impossible means of travel. Youll get crushed cause its technically a black hole, cant escape for the seem reason, and if you were to crush Earth down to blackhole size it would be smaller than a gulf ball. To have enough mass or energy to create one should be impossible and you wouldnt want to go near it if you could!
Uh, no; white holes are simply (maximal) extensions of black hole solutions that span 'two universes', and they 'live' on the 'other side' - that's why they're meaningless. The Big Bang, on the other hand, is a completely different mathematical solution; I understand even theoreticians (Smolin, I guess?) have stated WH=BB, but taken literally within GR that's just wrong; they probably mean something different, or in the context of their own alt-theories of gravity and stuff As for _exotic_ matter, it's required to keep the mouths of the wormhole from collapsing due to their gravity - not a WH, which automatically exists if a BH exists
"everything from nothing" means nothing; Big Bang solutions don't tell you how the Universe was created, only as its size (AKA scale factor, Hubble's 'constant') depends on time, which is infinite; "Where did that energy come from?" To begin with, energy doesn't have to be conserved globally, and it isn't in GR (at least in an obvious way); this is no serious impediment, tho, for cosmological understanding
thstroyur hubbles constant was based thru radioactive dating which dating any rock is impossible. A half life cannot be completely determined due to the environment the object is in. Certain environments change the way atoms react. Like being frozen or being deprived of oxygen. Petrification or mummifieing.
I love that so many people enjoyed Stargate and still talk about it. I still re watch it. Such a good show. Was sad to see SGU be not so great and to see it go before we figured out what destiny was suppose to do.
I know what it has to do with - Beetlejuice came from a 3 way wormhole near Betelgeuse which is also connected to the sand lizard world. The decendants of the sand lizards are plotting to take over earth as we speak.
I always pictured wormholes more like how bubbles connect when you have one resting and another touching them specically straight down from above on top of it after enough time the two merge while still remaining in their general shapes. But what scares me about that thought process is that given enough time the two no longer keep their original shape and then become one supermassive hole consisting of what was once just a small connection becomes the entire shape connecting and warping each one around the other into a new cylindrical universe in SpaceTime that becomes the Wormhole which would continue to expand throughout the Universe and SpaceTime with gravity widening and then completely collapsing that Galaxy the same way changing the plane and structure around the wormholes
Leonard Susskind has said that even if blackholes can exist with connected wormholes that whatever goes in one end will never actually get shot out the other end, for the same reason you couldn't escape the other side.
It would travel like other cosmic bodies, albeit its mass would determine in which way it travels relative to the rest of the gravitational system it is in.
In Stargate (my favorite series BTW) wormholes are used in a more scientific accurate way. Maybe the pond thing is a bit fantastic, but the rest is quite good resolved: the gate opens the wormhole to the designated coordinates as well as keeping it open. The gate uses the pond to disintegrate matter into quantum elemental particles along with the original configuration (wich accoring to current models they can go seamlessly in the wormhole), then the reciver gate takes the information and re-assembles the particles into something. That's why they can radio broadcast both ways but not go backwards: the radio waves get funneled into the wormhole, but the gates are the ones in charge of proper safe transfer of matter. Yes I have been making a rewatch of the series.
Wormholes are pretty useless though if we can't travel through them. That is what Stephen Hawking suggests, at least. I hope he's not right on this one, and that there are actual wormholes that we can travel through. It would be very good for various sapient species across the universe.
Well, what if you can't travel through them, but you can at least communicate through them? That would be useful for when we start colonizing the stars. Even if we'd have to travel to them at sublight speeds at least we'd be able to talk to the colony in real time and they could send data back to us. Being able to stay in contact with your colonies is nothing to sneeze at. And if we ever advanced to the point that we can digitize our minds, then we wouldn't need to actually travel there at all as we could just send our minds! So while not as good as a Stargate wormhole, it would still have some use. Of course, this would mean you'd have to be able to build your own black hole and manipulate the fabric of spacetime in unknown ways to create a wormhole. Easily solved, right? lol.
Yeah, a tiny wormhole would at least let you fire modulated laser signals through it, for digital communication -- or eben several beams at several angles, which would come out the other side at several different angles [if you needed lots of bandwidth].
@David Stagg Mankind will create new and better "realities" way before we are able to manipulate this one on that scale. By the time we think of a way to visit other stars, there will be no need to.
Eventually, some of the light that's been reflected off your face could make its way into a black hole, potentially being spewed out some other end into the far reaches of space where no man could even dream of going.
Fun Fact: Isaac Newton was the first one to conjure up the theory of something he called a “Dark Star” which he described as stars without an escape velocity, though he never saw one, I think it’s safe to say that some of the credit should be reserved for Newton and his brilliancy.
The biggest problem with wormholes I see is that one would need to fold the space between the start and the destination. Nothing we have seen yet can fold such large amount of space, not even black holes.
What about the Big Bang? If parts of the universe come pre-folded due the the weird stuff happening in the first moments of the Big Bang, it is not a matter of how they form, if they are already there. Of course if they are inherently unstable then it is unlikely any would still remain. But that only sounded like a possibility, rather than a given.
In fact, come to think about it, a folded part of space-time might be a good place to look for the missing anti-matter. Who's absence from the universe we have yet to otherwise explain.
I suppose one way to detect if something is a white hole is if it seemed to "push" other stars and such away from it. Or maybe through observing some sort of strange divergent form of gravitational lensing.
My favorite worm hole scifi explanation came with a game called Independence War. I loved the first game a lot more. I believe it was because it was set in our home solar system. Anyway, the way they set up their fantasy was the wormholes were at Lagrange points and you needed a special capsule drive to manipulate them. I think this was my first space sim I ever played so I am a bit bias.
HOLY COW!!! I completely forgot about the show Sliders... I use to watch that when I was a kid. Now I gotta look it up and watch it again. Since it was so long ago I barely even remember anything about it.
It would probably help if we knew what to look for though. It has been proposed that we have in fact seen white holes, without being able to properly identify them as such. Despite what a lot of various space scientists might like you to believe, we really still know very little about what's out there
You heard it from me first cuz I'm calling it now! Black holes spew out the particles threw time and or location threw the wormhole. It assimilates in it's new location in a super dense god particle. Once it grows too dense it bursts creating a Big Bang/new universe. 👏🏻👏🏻👏🏻👏🏻👏🏻
I find it easiest to say "space-time is _malleable_" - it can be bent and stretched but always returns to its original shape. And this has been proven also with the detection of gravitational waves for if space-time were not malleable waves would not be able to propagate through it. Gravitational wanes propagate _through_ space-time itself, warping it, whereas electromagnetic waves propagate _within_ space-time, not warping it. Stands to reason too that if we can one day _generate_ gravitational waves that we'll be able to distort or _warp_ space-time at will. Now that we've detected them and can study them and as the resolution of our gravitational wave detectors improves we'll learn ever more. We've not yet studied any sort of wave and not ended up being able to create them ourselves.
Who said the quote at the top of your comment? I don't remember malleable meaning it can return to it's original shape. It just means it can be bent without breaking. Elasticity would work better there.
Spacetime is not malleable, nor is it required for wave propagation; what is malleable is a potential (metric field) that permeates everything. Do you know about how antennas work? Basically, all you need to make one is an oscillating source, and the same is true of grav-waves (just pick up the Earth and start shaking it; boom, you got waves); this is not a shocking prediction of GR, at all - but notice that this is completely different from actually _warping_ spacetime
Interestingly in recent years there's been talk about wormholes being an explanation for the "spooky action at a distance" of entanglement, basically that when two entangled quarks are created there is a wormhole between them. It's a possibility that can potentially help explain not only how entangled particles can interact faster than light but also apparently the math seems to suggest that gravity (aka the curvature of space time) is a result of quantum entanglement creating these wormholes. Of course it's all related to string theory and hypothetical and the math is over my head but the concept is pretty slick if it ever pans out. And if it does then not only do wormholes exist, they exist literally all over the place at the quantum scale between entangled virtual and real quarks and we experience their presence as gravity.
I remember watching something where the guy did the math for keeping a wormhole open, and a wormhole the size of a door would take the energy equivalent of the mass of Jupiter to keep open. Yikes, I think I'll stay far away from something with that much energy, thanks.
I often see the folded spacetime model of a wormhole, but folding spaetime that way would make creating a stable wormhole child's play in comparison! Anyway, I'm glad you pointed out that a wormhole may not be a shortcut. I'm thinking invariance on dimensions too: eg. if you are blocked by a wall in 2 dimensions you can use the third to climb over, which is a longer distance. Why would any higher dimensions be any different?
I have heard that maybe wormholes are part of quantum foam. If so, they are extremely tiny (smaller than a proton), don't go very far, and exist for an extremely short time.
Hot Communist A-10 Warthog Wormholes would in fact be 3-D. Like Interstellar since seems to be no other example of wormholes being 3-d. I think the obviously the only possible one.
I have a basic understanding of dimensions and wormhole. I know Nolan worked with a physicist and that the wormhole rendering was calculated but, I am not sure if they added stuff to make it more pleasing or when the rendering turns into massive science fiction, because as we all know the ending is massive science fiction
The physicist, Kip Thorne, published a wonderful book called "The Science of Interstellar." I definitely recommend it. He explains, in detail, how the ending actually *does* make scientific sense. Beyond that, the wormhole was about as accurate as they could get it. However, its traits are inconsistent; its outward appearance tells of a very short hole, while traveling through it was very long.
White holes maths was well explained by pbsspacetime channel. Its not actually a gate that spews radiation and subatomic particles into space-time. A white hole is the opposite of a blackhole in a very literal mathematical sense. Applying the Penrose diagram, a white hole is actually a black hole when you go backwards in time. So what i think is that a white whole can't actually exist in space-time to act like an exit of a wormhole unless its actually a blackhole and the time is flowing backwards and according to general relativity time dilation is true when space-time is bend and warped but we're not aware of any place in the universe where time actually flows backwards..
N: Vegeta what does the scouter say about his IQ level?! V: IT'S OVER NIIIIINNEEEE THOUSAAAAAAAND N: WHAT?! NINE THOUSAND?! There's no way that can be right!
Yeah, that's the definition of a white hole. If you _must_ give a physical interpretation, the 'otherverse' is just a mirror image of the 'realverse', you can't go there; after all, obtaining it is _kinda_ like using the method of images of electrodynamics ;)
Let's not forget that even if we could start construction on a wormhole today, we would probably still have to set up the other end, so if you wanted to go to, say the other end of the Milky Way, you'd still have to wait at least 100,000 years (if they travelled at the speed of light, which is kinda impossible) for our engineers to get to that future other end before you could go through.
Here's a thought on the stargate type wormhole: it has been explained that the gate (put simply) scans you, destroys you, stores you, sends you, reassembles you (similarly to startrek transportation). We also know that without disrupting gravity that lightspeed is essentially the max speed possible for any transmission in or through space-time. Knowing that, would wormhole travel (because it converts you to energy that can travel at luminal velocity) maximally be limited to luminal transmission rates, and therefore (because energy) the trip doesn't need to be instantaneous for the traveler and while traveling (even if it is millions or more LY trip) the traveler doesn't age. This would create a whole new problem to this kind of transportation. Mainly due to there being still however many LY distance to travel at or below luminal velocity. You'd step into it today and exit the luminal transit time later. So if the wormhole cuts a 3billion LY trip in normal space-time to a 1000 LY transit, you're still passing 1000 real years while in transit.
Using the bedsheet analogy we can infer indirectly that wormholes exist . Because if there is a wormhole . Then there must be a curvature in space time that would be directly related to their distance and the radius of wormhole . So we could in theory locate a wormhole by measuring a curvature of space (for example near a black hole ) but the curvature would be much different than near a black hole
That's not how wormholes works... wormholes mean that if two people enter two black holes connected by wormholes, and they travelled at the speed of light, they COULD meet somewhere in the einstein-rosen bridge. Anything slower wouldn't meet, and you would need to go faster than the speed of light to go to the other black hole.
conclusion:dont throw glasses into my stone because it isn't the bicycle wheel of my father...the poor cow then got ran over by a submarine while it was eating grass on the asphalt
I get that for two objects to meet in the middle, they'd have to travel at c. But I thought anything going into either black hole bridge would end up on the inside of the other black hole, regardless of the speed?
I am pretty sure the problem with relativity by itself is it dimples a sheet by a mass. It is not like ripely-wavey. The only real application in that manner is if there is a parallel universe or non-euclidean aspect to ours that allows connection to a parallel plane.
Don't forget Wormholes are also shortcuts in time, not only space. So by passing through one you could end up far far in the future where the Universe died long ago and you're the only thing left in existence. I'd rather not ever risk going through one, even if it was stable and safe to pass.
Interesting. I was thinking about it as if it's one of those graphs you learn in school, where there's an asymptote along the X-axis (aka, space-time) and the graph lines go upwards to infinity on one side of the asymptote and downwards to negative infinity on the other side. Imagine if a wormhole is just where those two lines going to infinity meet and instantly swap sides (the one going up being a white hole, and the one going down being a black hole).
So would a wormhole with a black hole at one end and a white hole at the other end need spacetime to be twisted into a Mobius loop kind of shape (but in 4D, of course)?
Ah, this brings me back to the early days of our research. You're right that only way to test this would be to send a person inside a black hole. Which we did; we sent Jerry. Because no one likes Jerry.
On the bedsheet analogy the wormhole is made by either two black holes or two white holes connected together - depending on which side of the sheet you are on. So not black hole into white hole. And why would you go through the wormhole and not just swing inside back and forth like a pendulum? :)
Another possibility is that the "exiting" end of the wormhole could be in another time. Say you enter one end in 2017 you could wind up tens or hundreds of years in the future or past bc technically you are going through a hole in the fabric of space time
A wormhole is the hole inside of a worm where the poop comes out. With the right tools and knowledge we can use those holes to travel through time and space. I tell you all, it always are the little ones that you never expect.
A wormhole would be amazingly hard to detect. It's just a doorway, you wouldn't see any swirling vortices of glowing plasma or anything like that because there is no energy or mechanism in a wormhole to generate such things. It would look like one of the portals in the game "Portal" except the it would spherical in shape, not a disc and wouldn't have any glowing border like the the portals in the game have. You would just see a starfield overlaid on the background starfield in every band of the electromagnetic spectrum. So good luck detecting that unless you literally pass through one.
If a whitehole and a black hole must sit on opposite ends of a worm hole, what would have if they continued to go around the “bedsheet” until they came to a part where they met up? What would happen?
I think it's just an artifact of language. The fact that you can describe something with words doesn't mean that thing exist in the real world, like 'unicorn' of a 'circular square'. Math is a language as well, and it creates artifacts of its own.
So are there any theories as to what would happen if you theoretically were traveling through a wormhole and it collapsed while you were inside? Which part of the bed would you be on? I'm guessing the wrong side..
Actually a wormhole is a loop of energy traveling through a region of space completely void of causality. Causality drives Observation, and therefor Time. So without Causality, Time cannot pass. Wormholes travel between Dimensions of Observation like an infinite funnel, but the region of space between each end is a boundary of causality so no time can pass or be observed from any relative point of observation. The key feature of a funnel to keep in mind is, Large at one end, and Small at the other. What comes out the other side of a Wormhole is matter compressed into a smaller area with a smaller cloud of probability containing the tiny fields of energy at the center of all particles containing mass. (spoiler alert all particles contain energy, and mass is energy being acted upon by causality, so all particles have mass whether or not we can observe it) To travel through a Wormhole is to travel to a new Dimension of Observation by means of mechanical compression. The Dimension of Observation you end up in should, for all intents and purposes, be identical to the one start in, but on a different scale of Infinity. That is assuming your consciousness could survive compression, which it cannot. Every particle interaction in the Quantum Foam is an infinitely smaller Dimension of Observation that a Wormhole is making a connection to. Like a drain pipe that gets infinitely small. The real fun part to think about is our Dimension of Observation also being just a blip in an infinitely larger Sea of Quantum Foam where our entire 96 billion light year Dimension of Observation is nothing but a tiny particle erupting from the Ether, and annihilating itself. Infinite, infinity.
I can understand why the heavy object on a flat plane model is used to explain gravity and black holes...but it really isn't accurate when you think about it. Gravity doesn't focus on one direction at a time. It goes in all directions equally. So there wouldn't actually be a hole but rather an infinitely small and dense sphere. You don't fall into a black hole but rather onto it. It just compacts you into that same unimaginable space it fills with the force of its gravity.
Theory: if a massive enough object could perform multiple slingshot maneuvers across multiple star systems, could ‘wormholes’ be created in its wake? What happens if multiple massive enough objects were sent to do the same?
scientists in spain created a tiny wormhole between two magnets I think, and they succeeded in moving some magnetic field from a point to another point, idk exactly but it's on seeker's channel
Question: what is the shape of a blackhole? Is a blackhole 2-d and flat? And if so do both sides suck in? We only show blackholes in a 2-d way with one side sucking in, so what does that mean if you’re on the other side? Are both sides the same?
I think that it is possible that wormholes exists, but it is impossible to go through it. Because we describe bends and curves in space time in a two dimensional plane and a 3d curve. But if it would be a tunnel, then in real life wormholes would be 4 dimensional objects that kind of bends spacetime in a different way
The thought of it being impossible for us to ever achieve interstellar FTL travel really makes me depressed... I try to stay hopeful but it seems that the more we know about physics the less likely it is... :'(
It looks like all the good candidates for a 2nd home are light years away and we have absolutely no clue how we're going to traverse those distances. And earth is filling up fast. Just a tad bit scary.
Samantha Carter could explain to you why those Black hole wormholes would 100% not be usable you need some naquada and an ungodly ammount of titanium wire. And a toaster to make a miniature artificial worm hole.
The math also suggests that Einstein-Rosen Bridges may form along magnetic reconnection points. It has been suggested that NASA's Magnetospheric Multiscale Mission (MMS), three satellites launched in 2015 to study Earth's magnetosphere, may include, at least as part of it's mission, the search for such bridges. Have you any data on this?
A worm hole would only really work for how we describe space and not actually work for space... We say it's a bedsheet but it's not flat. Unless you mean to say you enter some opening and instantly "vanish" into another dimension somehow and pop out at another point. Makes it sound pretty unrealistic. IF space was flat it could work potentially but I honestly don't think it's possible anymore.
White holes/black hole wormholes are just a few ways wormholes could possibly exist. There is also expanded Quantum Tunnels that require an unknown type of matter/energy that causes time-space to expand.
Just wondering if maybe all this wormhole/ black hole dying, spaghettification stuff is just like the human body cannot travel faster than 30 mph or the flesh will rip off the body type response? Maybe we can just glide through them... No harm, no foul...Maybe we just need some type of molecular shield that keeps our body intact while in motion. Just curious...

The only possible existence we know of a White Hole is the Big Bang, surprised you didn't mention that because it's pretty interesting

It would travel like other cosmic bodies, albeit its mass would determine in which way it travels relative to the rest of the gravitational system it is in.
If wormholes ever turn out to exist, I bet it would require quantum entanglement on a massive scale.

You forgot Farscape. That show's entire plot revolved around wormholes.
There have been tonnes it would be a waste of time to mention all of them
In Stargate (my favorite series BTW) wormholes are used in a more scientific accurate way. Maybe the pond thing is a bit fantastic, but the rest is quite good resolved: the gate opens the wormhole to the designated coordinates as well as keeping it open. The gate uses the pond to disintegrate matter into quantum elemental particles along with the original configuration (wich accoring to current models they can go seamlessly in the wormhole), then the reciver gate takes the information and re-assembles the particles into something. That's why they can radio broadcast both ways but not go backwards: the radio waves get funneled into the wormhole, but the gates are the ones in charge of proper safe transfer of matter.
Yes I have been making a rewatch of the series.
Wormholes are pretty useless though if we can't travel through them. That is what Stephen Hawking suggests, at least. I hope he's not right on this one, and that there are actual wormholes that we can travel through. It would be very good for various sapient species across the universe.
Well, what if you can't travel through them, but you can at least communicate through them? That would be useful for when we start colonizing the stars. Even if we'd have to travel to them at sublight speeds at least we'd be able to talk to the colony in real time and they could send data back to us. Being able to stay in contact with your colonies is nothing to sneeze at. And if we ever advanced to the point that we can digitize our minds, then we wouldn't need to actually travel there at all as we could just send our minds! So while not as good as a Stargate wormhole, it would still have some use.
Of course, this would mean you'd have to be able to build your own black hole and manipulate the fabric of spacetime in unknown ways to create a wormhole. Easily solved, right? lol.
Yeah, a tiny wormhole would at least let you fire modulated laser signals through it, for digital communication -- or eben several beams at several angles, which would come out the other side at several different angles [if you needed lots of bandwidth].
@David Stagg
Mankind will create new and better "realities" way before we are able to manipulate this one on that scale. By the time we think of a way to visit other stars, there will be no need to.
Eventually, some of the light that's been reflected off your face could make its way into a black hole, potentially being spewed out some other end into the far reaches of space where no man could even dream of going.
When is Wormhole X-Treme finaly comming to Netflix?
I don't know but I've heard that some of the CGI in it is amazing.
Wait. I thought that was the fictional, in-universe Stargate Show within Stargate SG-1
Fun Fact: Isaac Newton was the first one to conjure up the theory of something he called a “Dark Star” which he described as stars without an escape velocity, though he never saw one, I think it’s safe to say that some of the credit should be reserved for Newton and his brilliancy.
So not weirder than we could imagine. I believe Event Horizon covered this with a nudy mag.
The biggest problem with wormholes I see is that one would need to fold the space between the start and the destination. Nothing we have seen yet can fold such large amount of space, not even black holes.
What about the Big Bang? If parts of the universe come pre-folded due the the weird stuff happening in the first moments of the Big Bang, it is not a matter of how they form, if they are already there.
Of course if they are inherently unstable then it is unlikely any would still remain. But that only sounded like a possibility, rather than a given.
In fact, come to think about it, a folded part of space-time might be a good place to look for the missing anti-matter. Who's absence from the universe we have yet to otherwise explain.
@@valken666 it could be simpler than we think but are minds just hasnt comprehend it yet
Hahaha, I iloveyou the guy who does the Event Horizon podcast!
I suppose one way to detect if something is a white hole is if it seemed to "push" other stars and such away from it. Or maybe through observing some sort of strange divergent form of gravitational lensing.
I know a whole fandom who would have a Bajor problem with wormholes not existing.
Indeed!
New Message who
HA. HA. HA.
(well played, well played....)
I found this comment to be very punny indeed.
Because without the wormhole an entire civilisation would be without Bajor Prophets
My favorite worm hole scifi explanation came with a game called Independence War. I loved the first game a lot more. I believe it was because it was set in our home solar system.
Anyway, the way they set up their fantasy was the wormholes were at Lagrange points and you needed a special capsule drive to manipulate them. I think this was my first space sim I ever played so I am a bit bias.
Of course, or else there wouldn't be worms! 😮
HOLY COW!!! I completely forgot about the show Sliders... I use to watch that when I was a kid. Now I gotta look it up and watch it again. Since it was so long ago I barely even remember anything about it.
Wouldn't an observable White Hole be ridiculously detectable? Even if very brief?
It would probably help if we knew what to look for though. It has been proposed that we have in fact seen white holes, without being able to properly identify them as such. Despite what a lot of various space scientists might like you to believe, we really still know very little about what's out there
+TheTayz It would, if we'd know what to look for. It was even theorized that the Big Bang might have been one such white hole actually.
Didn't we detect a huge blast of light in 2006 that supposedly came from nowhere and thus might be a white hole? .o.
@@MrMega1423 one year later , um sorry nope. , No yet , I n this universe .
@@mikestevens8012 You sure you did your research right?
You heard it from me first cuz I'm calling it now! Black holes spew out the particles threw time and or location threw the wormhole. It assimilates in it's new location in a super dense god particle. Once it grows too dense it bursts creating a Big Bang/new universe. 👏🏻👏🏻👏🏻👏🏻👏🏻
I find it easiest to say "space-time is _malleable_" - it can be bent and stretched but always returns to its original shape. And this has been proven also with the detection of gravitational waves for if space-time were not malleable waves would not be able to propagate through it. Gravitational wanes propagate _through_ space-time itself, warping it, whereas electromagnetic waves propagate _within_ space-time, not warping it.
Stands to reason too that if we can one day _generate_ gravitational waves that we'll be able to distort or _warp_ space-time at will. Now that we've detected them and can study them and as the resolution of our gravitational wave detectors improves we'll learn ever more. We've not yet studied any sort of wave and not ended up being able to create them ourselves.
Who said the quote at the top of your comment? I don't remember malleable meaning it can return to it's original shape. It just means it can be bent without breaking. Elasticity would work better there.
Spacetime is not malleable, nor is it required for wave propagation; what is malleable is a potential (metric field) that permeates everything. Do you know about how antennas work? Basically, all you need to make one is an oscillating source, and the same is true of grav-waves (just pick up the Earth and start shaking it; boom, you got waves); this is not a shocking prediction of GR, at all - but notice that this is completely different from actually _warping_ spacetime
Interestingly in recent years there's been talk about wormholes being an explanation for the "spooky action at a distance" of entanglement, basically that when two entangled quarks are created there is a wormhole between them. It's a possibility that can potentially help explain not only how entangled particles can interact faster than light but also apparently the math seems to suggest that gravity (aka the curvature of space time) is a result of quantum entanglement creating these wormholes.
Of course it's all related to string theory and hypothetical and the math is over my head but the concept is pretty slick if it ever pans out. And if it does then not only do wormholes exist, they exist literally all over the place at the quantum scale between entangled virtual and real quarks and we experience their presence as gravity.
Maybe there's an Alaskan Bullworm in space that digs through time?
I remember watching something where the guy did the math for keeping a wormhole open, and a wormhole the size of a door would take the energy equivalent of the mass of Jupiter to keep open. Yikes, I think I'll stay far away from something with that much energy, thanks.
Lol. Btw Stargate was great. Except I hated the replicators.
Slidering? Even on the series, Sliders, they call it, sliding. Hank Green, come on now lol. I love this channel!
Yes, we need more SG1, SGA and SGU.
Mostly SG1 and SGA though lol
A better SGU
oh yeah SGU happened... :(
I often see the folded spacetime model of a wormhole, but folding spaetime that way would make creating a stable wormhole child's play in comparison!
Anyway, I'm glad you pointed out that a wormhole may not be a shortcut. I'm thinking invariance on dimensions too: eg. if you are blocked by a wall in 2 dimensions you can use the third to climb over, which is a longer distance. Why would any higher dimensions be any different?
Yeah there are plenty in my garden.
I have heard that maybe wormholes are part of quantum foam. If so, they are extremely tiny (smaller than a proton), don't go very far, and exist for an extremely short time.
wouldthe interstellar rendering of a wormhole be the most accurate one we could imagine
Hot Communist A-10 Warthog
Wormholes would in fact be 3-D. Like Interstellar since seems to be no other example of wormholes being 3-d. I think the obviously the only possible one.
I have a basic understanding of dimensions and wormhole. I know Nolan worked with a physicist and that the wormhole rendering was calculated but, I am not sure if they added stuff to make it more pleasing or when the rendering turns into massive science fiction,
because as we all know the ending is massive science fiction
The physicist, Kip Thorne, published a wonderful book called "The Science of Interstellar." I definitely recommend it. He explains, in detail, how the ending actually *does* make scientific sense. Beyond that, the wormhole was about as accurate as they could get it. However, its traits are inconsistent; its outward appearance tells of a very short hole, while traveling through it was very long.
This guy is my favorite. Thank you for being awesome
It's impossible. No.
It's necessary
White holes maths was well explained by pbsspacetime channel. Its not actually a gate that spews radiation and subatomic particles into space-time. A white hole is the opposite of a blackhole in a very literal mathematical sense. Applying the Penrose diagram, a white hole is actually a black hole when you go backwards in time. So what i think is that a white whole can't actually exist in space-time to act like an exit of a wormhole unless its actually a blackhole and the time is flowing backwards and according to general relativity time dilation is true when space-time is bend and warped but we're not aware of any place in the universe where time actually flows backwards..
I already knew all of this, I watch Rick & Morty
N: Vegeta what does the scouter say about his IQ level?!
V: IT'S OVER NIIIIINNEEEE THOUSAAAAAAAND
N: WHAT?! NINE THOUSAND?! There's no way that can be right!
Lol me too
In the name of science, I would gladly volunteer to be sent into a wormhole as long as ample provisions were made to compensate my loved ones.
I like the assumption that a black hole doesnt have another side. Obviously the other side of every blackhole is a new universe DUH
Yeah, that's the definition of a white hole. If you _must_ give a physical interpretation, the 'otherverse' is just a mirror image of the 'realverse', you can't go there; after all, obtaining it is _kinda_ like using the method of images of electrodynamics ;)
Every one is a Gangsta till Light Can't Scape
Why aren't white holes called white hills, then?
Let's not forget that even if we could start construction on a wormhole today, we would probably still have to set up the other end, so if you wanted to go to, say the other end of the Milky Way, you'd still have to wait at least 100,000 years (if they travelled at the speed of light, which is kinda impossible) for our engineers to get to that future other end before you could go through.
Slidering? Really, Hank? Really?
"Once you get too close to a black hole, you are toast"? No! You're spaghetti! (He said, saucily.) You pointed that out just a few episodes ago.
ER=EPR
Why no mention of this?
Because nobody cares about Podolsky
If the topic is wormholes then surely the concept of ER=EPR should be addressed.
Here's a thought on the stargate type wormhole: it has been explained that the gate (put simply) scans you, destroys you, stores you, sends you, reassembles you (similarly to startrek transportation). We also know that without disrupting gravity that lightspeed is essentially the max speed possible for any transmission in or through space-time. Knowing that, would wormhole travel (because it converts you to energy that can travel at luminal velocity) maximally be limited to luminal transmission rates, and therefore (because energy) the trip doesn't need to be instantaneous for the traveler and while traveling (even if it is millions or more LY trip) the traveler doesn't age. This would create a whole new problem to this kind of transportation. Mainly due to there being still however many LY distance to travel at or below luminal velocity. You'd step into it today and exit the luminal transit time later. So if the wormhole cuts a 3billion LY trip in normal space-time to a 1000 LY transit, you're still passing 1000 real years while in transit.
That’s not a wormhole then
No
WildWestWizard Pretty convincing argument.
can't argue with that
Using the bedsheet analogy we can infer indirectly that wormholes exist . Because if there is a wormhole . Then there must be a curvature in space time that would be directly related to their distance and the radius of wormhole . So we could in theory locate a wormhole by measuring a curvature of space (for example near a black hole ) but the curvature would be much different than near a black hole
That's not how wormholes works... wormholes mean that if two people enter two black holes connected by wormholes, and they travelled at the speed of light, they COULD meet somewhere in the einstein-rosen bridge. Anything slower wouldn't meet, and you would need to go faster than the speed of light to go to the other black hole.
conclusion:dont throw glasses into my stone because it isn't the bicycle wheel of my father...the poor cow then got ran over by a submarine while it was eating grass on the asphalt
hemen that makes perfect sense you should write a book with that logic
hemen112 you just blew my mind
I get that for two objects to meet in the middle, they'd have to travel at c. But I thought anything going into either black hole bridge would end up on the inside of the other black hole, regardless of the speed?
+hemen112
Is it bad that what you wrote kind of made sense to me?
I am pretty sure the problem with relativity by itself is it dimples a sheet by a mass. It is not like ripely-wavey. The only real application in that manner is if there is a parallel universe or non-euclidean aspect to ours that allows connection to a parallel plane.
Don't forget Wormholes are also shortcuts in time, not only space. So by passing through one you could end up far far in the future where the Universe died long ago and you're the only thing left in existence. I'd rather not ever risk going through one, even if it was stable and safe to pass.
Interesting. I was thinking about it as if it's one of those graphs you learn in school, where there's an asymptote along the X-axis (aka, space-time) and the graph lines go upwards to infinity on one side of the asymptote and downwards to negative infinity on the other side.
Imagine if a wormhole is just where those two lines going to infinity meet and instantly swap sides (the one going up being a white hole, and the one going down being a black hole).
So would a wormhole with a black hole at one end and a white hole at the other end need spacetime to be twisted into a Mobius loop kind of shape (but in 4D, of course)?
You’re wrong, Hank. You’re not toast once you come close enough to a black hole- you’d be spaghetti.
I thought the Lorentzian Wormhole at 0:45 was a Lovecraftian Wormhole at first glance and was briefly terrified.
Ah, this brings me back to the early days of our research. You're right that only way to test this would be to send a person inside a black hole. Which we did; we sent Jerry. Because no one likes Jerry.
We'll never be able to even reach a black hole to try it out without using a wormhole to get there.
Very satisfied by that Sliders reference. 10/10.
Two blackholes that have collided might be able to create a wormhole I think.
On the bedsheet analogy the wormhole is made by either two black holes or two white holes connected together - depending on which side of the sheet you are on. So not black hole into white hole. And why would you go through the wormhole and not just swing inside back and forth like a pendulum? :)
Another possibility is that the "exiting" end of the wormhole could be in another time. Say you enter one end in 2017 you could wind up tens or hundreds of years in the future or past bc technically you are going through a hole in the fabric of space time
When you gave the whitehole analogy I just thought of another thing that pokes up in a bed sheet.
A wormhole is the hole inside of a worm where the poop comes out.
With the right tools and knowledge we can use those holes to travel through time and space.
I tell you all, it always are the little ones that you never expect.
If you get too close to a black hole you "are not toast". You become spaghetti.
A wormhole would be amazingly hard to detect. It's just a doorway, you wouldn't see any swirling vortices of glowing plasma or anything like that because there is no energy or mechanism in a wormhole to generate such things. It would look like one of the portals in the game "Portal" except the it would spherical in shape, not a disc and wouldn't have any glowing border like the the portals in the game have. You would just see a starfield overlaid on the background starfield in every band of the electromagnetic spectrum. So good luck detecting that unless you literally pass through one.
If a whitehole and a black hole must sit on opposite ends of a worm hole, what would have if they continued to go around the “bedsheet” until they came to a part where they met up? What would happen?
I think it's just an artifact of language. The fact that you can describe something with words doesn't mean that thing exist in the real world, like 'unicorn' of a 'circular square'. Math is a language as well, and it creates artifacts of its own.
Hehe Slider reference, surprised anyone remembers that show. Loved the alt history stuff they had.
So are there any theories as to what would happen if you theoretically were traveling through a wormhole and it collapsed while you were inside? Which part of the bed would you be on? I'm guessing the wrong side..
Wormholes in a bed sheet. Is that the follow up to The Universe in a Nutshell? LOL.
Actually a wormhole is a loop of energy traveling through a region of space completely void of causality. Causality drives Observation, and therefor Time. So without Causality, Time cannot pass. Wormholes travel between Dimensions of Observation like an infinite funnel, but the region of space between each end is a boundary of causality so no time can pass or be observed from any relative point of observation.
The key feature of a funnel to keep in mind is, Large at one end, and Small at the other. What comes out the other side of a Wormhole is matter compressed into a smaller area with a smaller cloud of probability containing the tiny fields of energy at the center of all particles containing mass. (spoiler alert all particles contain energy, and mass is energy being acted upon by causality, so all particles have mass whether or not we can observe it)
To travel through a Wormhole is to travel to a new Dimension of Observation by means of mechanical compression. The Dimension of Observation you end up in should, for all intents and purposes, be identical to the one start in, but on a different scale of Infinity. That is assuming your consciousness could survive compression, which it cannot. Every particle interaction in the Quantum Foam is an infinitely smaller Dimension of Observation that a Wormhole is making a connection to. Like a drain pipe that gets infinitely small.
The real fun part to think about is our Dimension of Observation also being just a blip in an infinitely larger Sea of Quantum Foam where our entire 96 billion light year Dimension of Observation is nothing but a tiny particle erupting from the Ether, and annihilating itself. Infinite, infinity.
I can understand why the heavy object on a flat plane model is used to explain gravity and black holes...but it really isn't accurate when you think about it. Gravity doesn't focus on one direction at a time. It goes in all directions equally. So there wouldn't actually be a hole but rather an infinitely small and dense sphere. You don't fall into a black hole but rather onto it. It just compacts you into that same unimaginable space it fills with the force of its gravity.
I always thought that whatever went into a black hole went all the way to the singularity and made it even bigger.
Theory: if a massive enough object could perform multiple slingshot maneuvers across multiple star systems, could ‘wormholes’ be created in its wake? What happens if multiple massive enough objects were sent to do the same?
Getting blasted out the white hole sounds terrifying.
scientists in spain created a tiny wormhole between two magnets I think, and they succeeded in moving some magnetic field from a point to another point, idk exactly but it's on seeker's channel
Question: what is the shape of a blackhole? Is a blackhole 2-d and flat? And if so do both sides suck in? We only show blackholes in a 2-d way with one side sucking in, so what does that mean if you’re on the other side? Are both sides the same?
Oh how I miss Babylon 5. Haven’t thought of that show in years! Thanks for the memories!
I think that it is possible that wormholes exists, but it is impossible to go through it. Because we describe bends and curves in space time in a two dimensional plane and a 3d curve. But if it would be a tunnel, then in real life wormholes would be 4 dimensional objects that kind of bends spacetime in a different way
The thought of it being impossible for us to ever achieve interstellar FTL travel really makes me depressed... I try to stay hopeful but it seems that the more we know about physics the less likely it is... :'(
It looks like all the good candidates for a 2nd home are light years away and we have absolutely no clue how we're going to traverse those distances. And earth is filling up fast. Just a tad bit scary.
Samantha Carter could explain to you why those Black hole wormholes would 100% not be usable you need some naquada and an ungodly ammount of titanium wire. And a toaster to make a miniature artificial worm hole.
The math also suggests that Einstein-Rosen Bridges may form along magnetic reconnection points. It has been suggested that NASA's Magnetospheric Multiscale Mission (MMS), three satellites launched in 2015 to study Earth's magnetosphere, may include, at least as part of it's mission, the search for such bridges. Have you any data on this?
The brain opens a wormhole every night we go to sleep.
We go to another reality.
A worm hole would only really work for how we describe space and not actually work for space... We say it's a bedsheet but it's not flat. Unless you mean to say you enter some opening and instantly "vanish" into another dimension somehow and pop out at another point. Makes it sound pretty unrealistic. IF space was flat it could work potentially but I honestly don't think it's possible anymore.
White holes/black hole wormholes are just a few ways wormholes could possibly exist. There is also expanded Quantum Tunnels that require an unknown type of matter/energy that causes time-space to expand.
Thank you. I'm so horrible at grammar.
Just wondering if maybe all this wormhole/ black hole dying, spaghettification stuff is just like the human body cannot travel faster than 30 mph or the flesh will rip off the body type response? Maybe we can just glide through them... No harm, no foul...Maybe we just need some type of molecular shield that keeps our body intact while in motion. Just curious...
Ok, SciShow. You've discussed wormholes. How about a video on hyperspace?
