Wormhole Questions

[@MrZerausogaitnas]

"oh brady"

[@kpw84u2]

LOL

[@MrSol3fool]

I just wanna take Ed home and have him in my room, ask him a complex question about the universe and then go to sleep to him answering it.

[@steveybingoluia8110]

LOL same

[@rohanabraham4169]

fatnomen lol I'm dying

[@georgeeliotevans3751]

while he watch you creepily as you sleep????

[@t64169]

it wouldn't feel creepy. I'd feel safer.

[@julio_scissors]

It doesn't matter how awful or stressful of a day I've had, Ed's videos always put me in a happy state. They should put his voice in a pill a sell it as anti-anxiety medicine.

[@rohanabraham4169]

otteaux yeah I love his attitude

[@toxicgraphix]

l like prof. Ed, he just seems like a nice guy... and he explains things in an easy to understand way. ...and even if you don't understand what he's talking about. ..at least you have a nice smile to end your day.

[@salottin]

He's the best!

[@nervozaur]

It's such a pleasure to listen to these professors talk. I can never get enough of these videos.

[@cyris8400]

It would be an awesome prank on students if a physics professor had an identical twin who entered the lecture hall during a talk on this stuff and pretended to be the professor's future self who traveled back in time via wormhole.

[@tedsimmons4756]

Somewhere in the multiverse...

[@Skindoggiedog]

Copeland and Moriarty are brilliant to listen to. My brain just can't get enough of this!

[@themeankanin]

prof. Ed looks and sounds like such a varm and gentle man. comforting to listen to him.

[@Direkin]

I always enjoy coming back here to find new videos. It's like the last bastion of sanity on KZbin.

[@Donjone]

Man you are the best, i just enjoy hear you talking

[@jackhammer2002]

between his calming voice and cheery demeanor he seems like a wonderful person to be around

[@k.c.lejeune6613]

jackhammer2002 Professor Ed is the GREATEST!

[@kidmohair8151]

Is the Uni of Nottingham populated/overrun with these absolutely brilliant teachers?? what a nirvana!!

[@davsbrander]

@matics19 Listening to him is one thing, sitting an exam set by him is another altogether... I speak from experience and I still don't sit the same way since that paper violated me... :)

[@shivanshutewari3682]

Was it that though?

[@bluebychoice]

Prof Copeland has such a succinct way of explaining things. It's great.

[@lekoman]

Every video with Professor Ed starts with him saying "Oh, Brady..." in that awesome accent of his. It's a little catchphrase. I love it. =D

[@davidwilkie9551]

Entanglement, as a concept of information distribution, is related to the scale-shifting transmission through "jump-space" via the spiralling down-up of a "worm-hole". Several science fiction stories from late 60s to early 70s had various suggestions for "inversion" of size to distance and back, all in an instant. No one seemed to have a practical mechanism at the time, although one was based on precession, so spinning discs created some sort of dimension modifying spiralling. The only plausible mechanism has to be a material equivalent of the sound to EM modulation and back, matter transmission which is via modulated wave-packages. The infinitive of Go by Brunner. (real fun) This being one of the most interesting speculations of SF, of course the choice of ideas is to somehow tune and phase-lock the "wave-package" to sender and receiver , and that is what entanglement is about.(?)

[@heyandy889]

I usually lean a bit more towards the main videos. However, in this case, I think the extended discussion gives me a clearer picture of what's going on.

[@integralmath]

@matics19: yeah, me too. I'm a mathematician, but when I talk to great physicists about the physical analogues to what I study, I'm sometimes bowled over: just awestruck - feeling slightly on the side of a young student just being taught something about a field I thought I knew a great deal about.

[@oreocookiedough]

His voice is so calming

[@1p2o3i]

@madzyadzy07 (2) In the first case you would step onto this new branch and experience something, but you would still not know if it matches the event had you not jumped forward, because that one happens on your original timeline and could be completely different. In the second case you would step over to the alternate parallel timeline and would still have the same problem of not knowing what happend in your original time.

[@1p2o3i]

@madzyadzy07 (1) Traveling forward the way Prof Copeland described it is not really time travel because you would be slowed down, you don't bend time. But traveling back in time would definitely be time travel. But there is a debate wether or not time travel creates a new branch of the current timeline you originate from at the point you started time traveling or even builds a bridge into a whole alternate timeline that exists parallel to ours. Or nothing changes at all.

[@kruelkiller]

"the thing that's being bent isn't just space..its also time.." :):):) REALLY MAN I LOVE U GUYS ! There's no way my physics prof can answer mind boggling questions so easily like that..:)

[@MadPuppets1]

i could listen to anyone who is willing to tell me about physics for hours

[@twstdelf]

I love these videos, and really appreciate Brady's work. All of the scientists are excellent, but imo, Copeland, Merrifield, and Moriarty are tops - they make me feel like going back to school! :)

[@ztveng]

Yes. It isn't miliseconds, it's frames. Since the movie is shot in UK he's filming at 25 FPS. So it goes ...22, 23, 24, 00, 01... 25 pictures each second.

[@Merdam9]

I love the honest smile on his face while he talks about wormholes :D

[@mignik01]

@PianoKwanMan no u r not missing anything. u r not traveling faster than light locally. If you and a particle of light decide to go through a wormhole, the particle of light will get there faster than you. But yes, universally you will be traveling faster than light.

[@CrakenX]

I feel like Brady should start producing merch based on the different profs in his sixtysymbols and periodicvideos series. I would love a Dr. Copeland action figure. Or maybe some trading cards.

[@Electroblud]

I have often wondered: If you were to create negative matter/energy in some way, in order to not violate thermodynamics, you would have to create positive energy at the same time. It essentially is like taking a bit of empty space and pulling out some positive energy (which may be used to fuel a power plant?) in order to have some negative energy in your chunk of space. The total amount of energy in the universe would not change, but you could still build an infinite energy source with this (or just dump the energy you don't need and keep the negative energy to stabilize wormholes and have fun with warp travel). Is that how an Alcubierre type spaceship could be powered?

[@richisnang1]

i know, hes so smiley, he makes me smile :)

[@nervozaur]

One question to ask, "if we develop a warp drive technology that allows a space ship to travel at the speed of light" and we set that ship on way towards the first star, 4 light years away, how much time would it have passed on Earth for our observers when the astronauts would have reached their destination?

[@andor888]

***** Light - like all matter - is able to go through the wormhole with you. Essentially what happens is the distance you measure your velocity with in the "through the wormhole" situation is far less than what the distance in a "traditional" way of travel would be - for you, and also for the light. So if we were jumping in the wormhole at the same time, and I measured your speed while we were "in the wormhole", you would still be significantly slower than the light that came through with us. Relativity is not broken, everyone is happy.

[@jonathansenal9126]

In my lay person's mind, I think the best explanation of why wormholes, if they exist, involve time as a dimension, is evidenced by the fact that the wormhole massively reduces the time to travel in "real time"

[@TealeBritstra]

@madzyadzy07 Unfortunately, to my understanding, the contact between the 'positive' and 'negative' matter would annihilate both your foot and the ball and result in quite a lot (ie: a huge amount) of energy! Assuming your foot were made out of negative matter to prevent this, the energy generated would still be normal, 'positive' energy though. Negative energy is different and extremely hard to generate.

[@truesemite]

you guys are awesome keep the videos coming in because i can never get tired of it

[@1p2o3i]

@madzyadzy07 (3) In the third case nothing you would do by traveling anywhere through time would change anything and in that case your event would happen no matter if you skip there, return there or just wait. In that case you could probably speak of 'destiny'.

[@therealEmpyre]

I had heard that there might be tiny wormholes popping in and out of existence everywhere all the time as part of the quantum foam, sort of like virtual particles.

[@andregomesdeoliveira9653]

Quick question. Say we do it, say we manage to create a device (let's call it ""portal gun") that does manage to create both an entrance and an exit so we can actually travel through the wormhole from point A to point B. Hooray, Science 1 - Reality 0. My question is, if a wormhole is basically bending space, than if said wormhole were to collapse, the space it bent would never be what it was before the wormhole was formed, right? I think it would be completely devasted, am I right?

[@madzyadzy07]

If we could travel forward in time does that mean that destiny is pre determined because we would experience the same events an hour from present time by skipping forward as we would without skipping?

[@1p2o3i]

@madzyadzy07 How would you know that? You can only experience one event, either by waiting an hour or by skipping an hour. ;) You could never say what happend in the other situation unless you split your body and consciousness to experience both situations and then transfer the information about both events to each of you or a third person to prove the theory.

[@therealEmpyre]

Taking into account the rotation of the Earth, the orbit of the Earth around the sun, the orbit of the solar system around the center of the galaxy, and the movement of the galaxy, scientists have estimated our movement relative to the cosmic microwave background, and while it is very impressively fast (about 2 million MPH), it is very slow compared to the speed of light (about 675 million MPH), so the time dilation difference would not be significant.

[@madzyadzy07]

With negative mass that means negative energy doesn't it? That implies that something with negative mass would behave the opposite to mass? So if i kick a ball made with negative matter with force x it would accelerate towards my foot at the same rate as a regular matter ball would accelerate away from my foot?

[@PianoKwanMan]

So .. If you could go through a wormhole is distant space in an instant, you effectively travel faster than the speed of light? - light may take millions of years to get there, and yoiu get there in an instant, or am I missing something like wormholes takes time, but time is compressed into an instant?

[@mattlm64]

I don't see how traveling back in time could be possible. That's a paradox against causality. Going forward faster in time is proven to be possible by simply changing the relative speeds of objects. That makes sense and isn't a paradox against causality.

[@davidwilkie9551]

"We don't know", excellent advice.

[@Moronisaurus]

"oh Brady" hahaha .) Love it :)

[@TheThomasto123]

Since space and time bend, if the sun went missing. Then it would take 8 minutes for us to experience no sun. So Space, time, and gravity all behave as matter? Since it interacts to not go beyond the speed of light, right?

[@TheIdealGasLaw]

Cracks through time and space, wasn't that the theme of the last season of Doctor Who?

[@TealeBritstra]

@madzyadzy07 Actually, I think I may have misinterpreted your comment a little... I thought you meant 'negative matter' in the sense of 'antimatter', rather than matter having a negative mass. As to what happens between matter with negative mass and matter with positive mass - I have no idea! lol.

[@stardude692001]

What about super massive black holes they wouldn't spaghettify you and they would be spinning at insane speeds would any of that help?

[@squirrel0604]

loving the blackboard behind the prof :D

[@ztveng]

25 frames/sec actually, which makes sense since it's filmed in UK :)

[@therealEmpyre]

It doesn't work that way. You know that photons can only travel at the speed of light. Well, I have heard relativity described as saying that not only light but everything travels constantly at the speed of light through space-time. When you are motionless in space, you are traveling through time at the speed of light, which is "normal" speed. The faster you move through space, the slower you move through time. Photons travel through space at the speed of light, and experience no time at all.

[@mrautistic2580]

I love the math involved in wormholes.

[@MooImABunny]

why are the centisec counter in the timer at the bottom counting from 0 to 29? and why is that timer there anyways?

[@jflopezfernandez]

That's awesome, Professor Copeland worked at Fermilab!??!

[@Julzx]

i like this man! i learn new things from him on every new video!

[@Bobajobimus]

Never Say Never = Wise words from a wise man

[@aluisious]

That's an equation describing why I started as a physics major and graduated with a history degree.

[@kpw84u2]

You would HAVE to bend time AND Space, AT THE SAME TIME. The sun is travelling through the galaxy which is spinning itself -- as is the earth streaks while spinning around it. If you bend only time and not account for their shift in space, you will end up somewhere unexpected. 💁🏽‍♂️

[@madzyadzy07]

@1p2o3i Ok so if you travel forward and experience the event. then travel back to before you travelled forward and wait the hour. What happens then?

[@JLConawayII]

Making wormholes is easy. You just launch a cartoon rocket containing negative matter into a black hole, and then....well this next bit isn't quite clear, something about a plucked chicken. I really need to organize my notes better. Anyway, then you dive face-first and naked (this is crucial) into the black hole. Voila, instant wormhole travel to a fantastic mystery destination in a parallel universe.

[@suiterbug]

In order to understand the truth of this one must be willing to understand the truth about gravity... Gravity is a helical wave, unlike an electromagnetic wave. These formulas are based on a false principle of the atom and how it works. To see where we went wrong... I recommend reading "Future Science" by Maurice Cotterell or just look up some youtube videos that show the basics and you will see what I mean. Although the book does a more thurough explination.

[@iamkevinthecanadian]

If you can go forward in time by going really fast, just go very fast backwards.

[@ObjectsInMotion]

Yes, the difference between time dilation and what you are talking about is that the latter is impossible, and nonsense.

[@m00niee]

@matics19 Same, he's terrific.

[@marfnl2]

How come a wormhole can't just appear out of nothing? A wormhole has 2 end's right?.... So what if some ware else a wormhole gets made? Can it not open the other end somewhere close to earth?

[@FearlessSpinner]

"We're just throwing science at the wall and see what sticks!"

[@biain93]

How do you build a wormhole? Build a giant time worm.

[@jamieg2427]

Can you do a video about ER = EPR and recent developments concerning wormholes?

[@yannick_w]

These videos are awesome !!

[@XanderMarjoram]

@VCSandARM Lot's of teachers refuse to tell us when they ask, but I'm only at A-level. I assume that their reactions would be the same :/

[@scottwebber4540]

2020 and watching this for the 10th time

[@Athrun000]

Personally I do not see time dilation as a form of time travel... ...For me,time travel into the future in more of a leap forward in the timeline, in such a way that I would be able to meet the future me.

[@caiomarinho1]

So there may be a time warp to the very early universe? Cool.

[@Tephr1te]

or..... the skin represents the universe, and going through the core of the apple represents going through the 'time' dimension that we can't observe on the skin

[@TheThomasto123]

But I thought gravity was a bend that came from things with momentum and acceleration or mass.

[@kpw84u2]

What if every entangled pair of particles encapsulates a wormhole?

[@sakelaine2953]

Thanks for posting this stuff, it's great!

[@TheRealFlenuan]

Suppose a wormhole connects a point of high potential energy, e.g. due to gravity, with one of low potential energy. If an object is dropped between these two points such that it reaches the end of the wormhole at the lower point, won't it come back out of the higher one with continuous acceleration (and even, one can imagine, keep doing this _ad infinitum_), thereby violating conservation of energy? Why don't wormholes violate thermodynamics? Does it take extra energy to traverse them? I'm sure theoretical physicists have come up with the answer to this.

[@saemj]

What on earth is on that whiteboard ? It looks even more complicated than all that wormhole talk ^^

[@Inckman452]

nope, because you see...there is a small incredibly MASSIVE thing that has infinite gravity a black hole, it bends light, it bends space, it puts a halt to time...

[@Hythloday71]

So do worm holes allow for violation of conservation of momentum.

[@jony1495]

no.

[@iksderfredski]

That maths... the whiteboard is a genius.

[@thejameskan]

some great inforamtion here thanks

[@VCSandARM]

@matics19 thanks !

[@TheIdealGasLaw]

@hooloovoo1st I know but it's still cool!

[@Foxymophandlema1]

how I wish I understood Prof. Copeland's blackboard....

[@svetsguitarplaying3681]

Why it's not titled asmr?

[@VCSandARM]

@matics19 thank you! have a great day

[@oakenguitar3]

why would ever want to approach the speed to explore the galaxy when you have to deal with time dilation. That would more than likely be a suicide mission. I like the idea of wormholes or some type of warp drive better. How do you think an alien would try to visit us? are they using light speed or are they using wormholes. I think the answer is wormholes because it doesn't make any sense to travel the speed of light

[@SCAREDBANANA]

Why do people often dismiss time as the 4th dimension?

[@gl1tchofficial]

Brilliant.

[@iamnico36]

He seems so friendly :)

[@Anodoin]

That's why they're still working on it, it hasn't been solved yet.

[@BinaryStars100]

The four dimensional structure space-time cannot be visualized yet presenters are always giving visual examples. Researchers follow the grant money which is why people generally move on. In the case of Einstein, he moved on when an approach did not work. General Relativity was a failed enterprise to Albert Einstein because he could not unify it with classical electromagnetism.

[@schludy0]

why does he say "git" at the end ?!

[@VCSandARM]

I'd like to submit a request! I dont judge people by it, but I wonder.... are these brilliant profs and scientists religious? how about a video in which they say what their religion is if any. or is it bad for teachers there in Britain to discuss things like that, like here in the US ? it just popped into my head.

[@jerommeke69]

damn interesting!!!!! Thanks Brady and thank you professors!

[@gredangeo]

He's giving a thumbs up in the thumbnail. :)
