Why Time "Stops" in a Black Hole 

I really understand that blackhole is an astronomical object. But, the way we describe it by detail using fancy mathematics equation is all interpretations. Please don't think we know for sure what's there. We have only one way approach to analyze when it comes to universe. Light. That's all we can think of. Heavy objects do bend the light due to space curvature. That's 💯 Einstein proof!

@@naturemc2 The Mathematical proofs of black holes are derived specifically from Einstein's field equations. Thus we are quite confident it is correct. However, it's uncertain what happens to the particles themselves in such an extreme scenario at the creation of a blackhole. This will be discussed in my last video in this series.

@@ButWhySci Which requires to explain in Quantum story. Whereas, Einstein field theory is not a quantum theory. As well, gravity have nothing to do when we talk about particle levels detail. Gravity and quantum object don't talk to each other. As you said, it is mathematical derived from Einstein field theory. I follow up with your research work.

Oh okay because i thought it was 2 people about to get it on

so is this supposed to mean that time is somehow proportional to gravity? at the molecular level when u look into compressed hot matter it is also interacting, only the space is smaller, it is not static. there seems to be some unexplained contradictions.

me too

Seriously. As that part of the video played, it was like that mind-blown GIF for me. What a brilliant, intuitive demonstration! I understood the fact of the matter beforehand, but that demo made it a tangible idea in my mind, not just a concept that I knew was true but didn't understand why/how.

Same

Agreed, very tangible way to illustrate a bizarre fact of physics.

Same, my thought of time dimension was too human. That model made the idea of the time dimension click for me finally rather than the passage of seconds on a clock being all I could think of.

so you are learning about black hole while coding a block game?

What the horsey said ⬆️

its still non sense lol. they are just making things up , non of this has been observed.

You make no sense mate!

Are you on drugs?

What if instead of a rod you used an incredibly long human? As you extended it downward you would watch this person age and turn into a skeleton at their head end, meanwhile you're still holding on to their baby feed. I guess somewhere around the middle they're probably in their thirties or forties.

@@vice.nor.virtueeh time is a constant. Sure the ‘speed’ can vary but aging occurs at the exact same rate

Incredibly Long Human would make a pretty good name for a band 🤔😄

But I still don't think that answers the entire question. The rod will break, but what about a theoretically very strong rod is "dipped" into the event horizon and pulled back up with great force? Will the dipped part just vanish?

@@GenUrobutcher No one knows the true answer to this question. It is a fascinating thought experiment, but sadly not one we are ever likely to solve. My conjecture is that if you had a "magically" indestructible rod that was VERY long, and you are at one end and "dipped" the other end past the event horizon, I suspect that from your frame of reference, time would basically stop for the end of the rod inside the horizon, and therefore, the rod would become "stuck". You would not be able to push it in further nor pull it out regardless of how much force you applied to it. Of course, this is all academic, since there is no such thing as an indestructible rod.

PONS??!??!?!

My head hair stopped growning but my pubic hair around my scrotum, penis, and bee whole continues to grow and talk and smell awful all the time.

what i understand is. he is comparing time with distance. he is treating time like a distance. at 3:30 if radio wave speed is equal to 10x speed of light. the whole thing will change. time remains the same everywhere. for everyone

@@enjerth78 It could have been two weeks if we had done it 🙄

@@chaotickreg7024 Based on what? Hope?

This comment is golden. Thank you

@@chaotickreg7024 It could've been two weeks if we did a quarantine backed by martial law. This would prevent spread of the disease from anyone infected to anyone who wasn't infected until the point of it being non transmissible. However the political ramifications of that... well yeah you can see why only certain countries used that approach and most did not. Lockdowns, social distancing only slowed transmissions down. Having infected and non infected still working, shopping, and going all to the same places at the same time, while being crowded into one entrance for compliance reasons.. was never going to stop the spread of an infectious disease.

understated as well

It took me a good 4 seconds to understand

Using the term ‘underrated’ is overrated.

@@TheSCPStudio overused if you will

I don't get it

After reading this, I still don't understand but at least i know why speed of light isn't speed of light

So the speed of light is defined by the speed of causality which is determined by how fast the processor simulating our universe is running. Got it.

@@farrela3620 Hmm perhaps another example will help. Let's say we create a micro-universe where only three things happen: 1) something explodes 2) you hear the explosion 3) you cover your ears. After the third event, the universe reaches its end. And let's say all of this takes 3 seconds: 1 second for the explosion to occur, 1 second for you to hear it and another for you to cover your ears. Notice here how things don't happen instantaneously. You don't hear the explosion exactly when it happens. It takes some time for its effect to reach you. And after hearing the explosion, you don't instantly cover your ears. It takes some time for you to process and react to it. Because of this delay, this universe lasts 3 seconds. Now let's say there were no delay. What would happen? The explosion would occur, you'd hear it instantly and cover your ear instantly as well. All 3 things happen at the same instant and your universe would last 0 seconds i.e. time wouldn't exist in this universe. Compare this to our universe. There aren't just 3 things happening but well, too many to count. And so our universe lasts trillions of years. But if there were no delay/gap between the events, all of the uncountable things would happen at the same time and the universe would last 0 seconds. Geometrically, this is like the difference between a point and a line. Everything happening at the same instant is like everything happening at the same point in space. But as long as you have some gap between the events, the gaps add up and give us a length instead of a point. I hope this helps but let me know if it doesn't. I'll try to think of a better example 😅

@@WhiterunGuard11998 Eh.....kind of 😂

well I kinda understand, sort off.. so, I kinda don't understand the difference between real 'time' with the speed of casualty. From what I just read, you described what time is? (mind you, i don't have a background in physics)

That means a lot and thank you for taking the time to write that out. I don't want to monetize my channel in the foreseeable future because: A) It won't have any impact on the quality or release schedule of my content B) This is a passion project and I don't want to feel obligated to create videos because I am receiving money C) I want my primary focus to be on my real world research (What I'm paid for) and would like to finish those projects before seriously considering videos as a source of income But I do have plans to expand and incorporate the community in video creation if that day ever comes.

@@ButWhySci Ok, sounds logical and I respect that even more. Real-world research should come first! Then I'm looking forward for your expansion, good luck with everything.

Superb comment.

@@ButWhySci And what's your real-world research, if you don't mind sharing? I'm interested because your knowledge about details in physics, chemistry and even biology seems so vast and ubiquitous, that it's hard for me to locate your field.

Space did expand faster than the speed of light.

At far distances from any point, the space expands faster than light and the faster it expands the further you are. So, yes, space itself can expand (and in fact does it) much faster than light.

@@dariuszspiewak5624 but with that logic, darkness would technically be faster than light.

@@idkjustleavemebeplease If you call space "darkness," then yes, you are absolutely right.

@@idkjustleavemebeplease darkness does't really have a speed, it's just the lack of light. It's relative to the quantity of light, not the speed of it.

Yes, why is that! Could you say something more why you think that, I am very curious!

​@@theoryianabsolute8777 Tidal forcing, the same effect that raises the tides twice a day. Gravitational attraction is a function of distance known as the _inverse square law._ Suffice to say, it gets stronger the closer you are to the mass. Near a blackhole this is so extreme that as you approach you will noticeably feel that your feet are being tugged more than your head, giving you a stretching sensation like being on a rack. This sensation will grow until the sinews of your body are literally ripped apart. Then the effect will be so great that the bonds connecting your molecules will break until you are arranged into long strings falling into the black hole in a process called _spaghettification._ I do not imagine this would be an altogether pleasant experience. :) Nb: This is a simplified explanation. 1) Tides on Earth are more complex than that. 2) Strictly speaking gravity isn't a force and your atoms which are ripping apart are technically at rest because of physics way too complicated for a comments section.

How do you do that font is it like /this?/ >this?> `maybe this?`

Lmao

Gravity = time

The only anti-gravity device is velocity

doesn't have to really. Sure, in the neutral bubble yes. But for the purpose of measuring time dilation as shown you'd just need a hypothetical antigrav device to only unwarp spacetime in a sphere around the crew

@chuckstable165 It's incorrect to think of the negative energy density of the casimir effect as being truly negative energy, rather it's showing you that it's negative relative to the space around it, which is because even seemingly flat empty space has positive energy. There is no "negative work" that could be extracted from it. Otherwise you are right, you do require exotic negative energy matter to do a lot of time travelling shenanigans

I rather think gravity is simply a force which at a certain rate applies movement/acceleration force to things like quantums. Magnets do the exact same thing and I'm pretty sure they don't warp spacetime.

He should throw in some Sciencephile the AI in the too. :p

In theory. Ever been inside one ?

​@@Ridethebomb777well if through a theory you can make an accurate looking blackhole, before being discovered in 2019 then the theory about it may also come true

You still don't understand.

@@Ridethebomb777 i have

Yes, I heard Brian Cox say this. That if you fall into a black hole (and somehow stay intact), that you will not fall through space, you begin to fall through time - and you are basically moving towards the end of time. Endlessly fascinating objects.

It actually have sense

This is true to an extent however the time dialation of being in the black hole wouldn’t be crazy enough to go that fast from the outside viewers perspective i would say depending on the intensity of the black hole it could be a difference of years I’m not 100 percent in that one but you are obviously not dumb for even being able to conceptualize that most people can’t imagine that

​@@samuelquinutolo1306 To reach 10x speed of the rest of a resting mass, you need to go at 0.995c. Going 100x is about 0.996c. 1000x is about 0.9997c. As you can see, the closer you go to the speed of light the faster the universe goes per time unit you experience. Assuming you somehow go into a black hole and come out (faster than light), you reached the speed of light at some point, meaning the time the rest of the universe experienced is undefined. Either way, you couldn't have reached the speed of light because that takes infinite energy. You can't add a caveat on the "intensity" of black hole, since it's an impossible thing to speculate. If somehow we did manage to make it out of the black hole, time's already played out, since any "time" you spent in there was at the speed of light, and as the velocity of something approaches the speed of light, the time the universe experiences approaches infinity.

@@Alekaline explained that much better than I ever could

Time dilation has been debunked

Math truly is the language of the universe.

​@@chidi8449crazy how those ancient guys found it but I'm struggling to learn it even now.

​@@yboy898i dont think less than a thousand years is ancient

Perfectly said. His RU-vid will blow soon

I dont remember the first time I heard that, it might have been a pbs spacetime video, but it's what I think about every time I see black holes. It was like what you would see if u could see in a black hole and it was something along: as you fall in, you go into the past, and everything above you is the future. You are traversing time by and only by moving through space, and so you are traversing time through the space axis.

@@Runeite51 Yeah I think it was pbs space time where I heard it as well. They describe things in such a great way

Hm

@chuckstable165 there's always talk about the event horizon etc that noone can ever pass etc but black holes don't last forever either it's said

That event in the future is the moment the last quantum of information has left it. Singularities are 4-dimensional objects with apparently, 0 size and extreme gravity but not infinite.

It’s genius isn’t it

Its a bad visualization. Uses gravity to demonstrate gravity. Spacetime contracts into black holes, as demonstrated in ScienceClic’s videos

speed up the spacetime to faster than light speed

You're comparing apples to oranges. Its a nice thought but its logic is flawed in the same way that pailey's watchmaker argument is flawed; you're trying to compare two systems where one is actually embedded in the other. Black holes are higher dimensional "objects" that do not follow the same rules as space-time in stable regions while water going down a spillway is part of those stable region. Higher dimensional analogies will need to be made in order for people to convey and understand the nature of these peculiar regions of our universe.

"To where?" *_Me_*

@@Rastasandrainbows Black holes are bound to the same four dimensions that spillways are bound to.

Time doesnt actually slow down though. It just SEEMS like it does from the point of view of another observer

😅😅😅

It's closer to being pulled into the 4th dimension and us not being able to pull it back. A third option is thus that to our experience, it's utterly demolished, while in reality, the gravitational pull is so strong that it tilts the rope into the 4th dimension. As for the force added to the rope, nah, the rope itself would have 1 million times more impact on the size of the black hole than the force you would be applying to it. There is quite a decent case to be made that any higher dimension would be percieved as time. If you were to take a picture of every single moment that happens on a 2d world, and stack them together, you would have a 3 dimensional stack of images containing the full timeline of the 2d world. So to us, it would just be 3 spacial dimensions, while to the 2d creatures on the 2d world, they have 2 spacial dimensions and 1 temporal dimension. Both time and space are relative, and are calculated as one and the same: Spacetime. Where our math often seems to break in consistency, is when space turns into time, or time turns into space. While quite possibly, we've just been ignoring the possibility that they are one and the same

@@Shoarma2 I don’t believe in a higher dimension. And I suppose from that point, I don’t have any idea what you mean. Nor do I honestly want to debate. 😊

@@Djt4848 I think a big misunderstanding with more dimensions is that its not neccesarily a higher dimension. Just a dimension with more angles. As for 4 dimensions, well, we dont need to believe in it, we already have 3 definitely spacial and 1 definitely temporal dimension. The question depends on how relative spacetime is, is there a definite line where time and space can be seperated, or can space shift into time just like matter and energy are 2 very different things, but still the same. You dont need to debate it, I just wanted to reply.

But this only because Hilbert error. The second aspect this is due to Espace Time Minkowski limit . But if we use Hermtian space time we never get the singularity. Why because Minkowski space stops a the Event horizon. When pressure is Reaching infinite. It happens before the Event horizon just for the sake Hilbert has never considered the existence of heavy small star like neutron star. This was not the case for Schwarzschild the man who was the first to determine the Event horizon. In February 1916 he calculated from the new publication of the Einstein equation for particules with mass. Eventually his paper demonstrated a particular very close to the event Horizon, the pressure has already reach infinite pressure. This is exactly the limit of the Minkowski space time. To talk what is it next needs to change space time model. One way to do it isti use Hermtian space time model . Eventually time become négative , ...and the mass becomes négative too. This is not antimatter. This is dark matter ....

​@@decomposedcorpse5186 I know it seems so forced

Its complex because its all nonsense. Haven't you figured that out yet? Time doesn't change because someone moved fast, while someone else watched them.. that's irrational garbage.

@@everythingisalllies2141 yeah it's counterintuitive, but not garbage

@@NKY5223 "counterintuitive" is just another way of saying that its irrational. And its certainly garbage, and easy to show why its garbage, but you are not interested in finding out, because you have already invested your beliefs in the official story.

@@everythingisalllies2141 can you show why or point to a source that says gr is garbage? im interested

@@NKY5223 well, I've studies SR more than GR, but both theories amount to science fraud. Many have figured out that in Science as well as in other aspect of life, we are constantly lied to, for various reasons. But that not what we are discussing here. I can explain exactly why SR is nonsense, and why it fools even intelligent people. But about GR, well you only need to take off your "Einstein is a genius" rose coloured glasses for a minute and wake up to a few of home truths, to see why GR is also a crock of shite. It goes like this: Space is just regions between objects where there are no other objects. It's that simple. And Time is just a concept that man uses to compare rates of change between those objects. So the claim that Time is a "dimension" in any way similar to actual distances, is silly at best, and a deceptive claim by tricksters at worst. We don't "travel through Time", because Time is just the motions of all objects in the universe, so it's not a destination, or a location, it's just really NOW, and a remembering of what was happening before NOW, and an expectation of what might happen a bit later than NOW. This is pretty basic and I should need to be explaining it, because its really self evident unless you already have a confused mind about the subject. So there is no such animal as "Spacetime", and it sure as hell could not get "curved" by non Euclidean Mathematics. When was the last time you managed to bend something by applying an equation to it? "Spacetime" is an abstract math only imaginary construct, and its "curvature" is only because they chose a non Euclidean coordinate system instead of the equally applicable Euclidean coordinate system. Both are able to locate any position in the universe, spherical coordinates are not superior or more "correct" than Euclidean coordinates. So, some math equations and an imaginary grid of points labelled "Spacetime" is never going to be the CAUSE of anything in Physics. Its not going to make you fall to the earth for example, because its all IMAGINARY and only "exists" on a Mathematicians blackboard. Meanwhile it's a real FORCE called Gravity that makes you fall. And what Minkowski does to a normal Graph and a standard rational PLOT of Time over Distance, is so very stupid that I laugh out loud, if it were not for the fact that Teachers actually seriously present it as if it were rational, while keeping a straight face. So if you are open minded, we can discuss the nonsense of SR. But I'm picking that your first instinct is to try to find why I'm wrong, rather than try to see if Einstein is wrong. He was no genius, nor am I, and you don't need to be to figure this stuff out. It's not rocket science. Just a series of very basic simple claims strung end to end. And half of the claims are incorrect assumptions, leading to the inevitable incorrect conclusions.
