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

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.

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.

Of course, or else there wouldn't be worms! 😮

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

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.

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.

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.

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 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.

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

Lol. Btw Stargate was great. Except I hated the replicators.

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?

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.

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..

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).

"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.

Two blackholes that have collided might be able to create a wormhole I think.

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.

You’re wrong, Hank. You’re not toast once you come close enough to a black hole- you’d be spaghetti.

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

Nice Sliders reference.

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.

Hehe Slider reference, surprised anyone remembers that show. Loved the alt history stuff they had.

3:04 im actually envisioning a volcano on the bedsheet now

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.

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.

best host ever-- get it? host? wormhole? gsus.

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.

Nice Sliders reference

I always thought that whatever went into a black hole went all the way to the singularity and made it even bigger.

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)?

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.

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

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?

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.

I know all about wormholes! Samantha Carter taught me ;)

Ok, SciShow. You've discussed wormholes. How about a video on hyperspace?

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.

That shirt is on point

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.

If you get too close to a black hole you "are not toast". You become spaghetti.

Wormholes in a bed sheet. Is that the follow up to The Universe in a Nutshell? LOL.

I want to live more to see that stuff.
