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!

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.

One thing to remember as well, is that in theoretical example of floating above the event horizon, the distances between atoms would stretched to maintain their positions within the fabric of spacetime (which is why the rod seems to be longer and longer from your perspective). So as a conscious being, the electrical impulses that make up our thought processes are actually traveling much greater distances and it takes longer for them to move between neurons. So as far as you are concerned time is moving normally be side you can only perceive time as fast as your neurons can transmit signals. In theory you could watch the entire history of the universe pass outside the black hole in a couple of minutes if spacetime is warped enough (and you didn't get Thanos'd by the warp ripping your atoms apart) because it takes the electricity THAT LONG to traverse the distances between your neurons.

I think if you were able to go into a black hole and theoretically come back out, there wouldn’t be anything to come back to anyway. Time would be moving so insanely fast outside the black hole relative to you that in a matter of seconds, the universe would experience the big freeze, crunch, rip or decay (theories for how the universe will eventually end). I’m pretty dumb so I have no idea if that would be true or not but it’s a cool/terrifying thing to think about.

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.

5:25 There is a reason, actually. People make this mistake because they associate the speed of light with.................well, light. When in fact it's the speed of causality. The value of this speed is arbitrary, but it must be finite. If it were infinite, all of the interactions in the universe would happen simultaneously, and time wouldn't exist. Think of the entire history of the universe until its end like a movie. The length of this movie is determined by how fast you play it. This is analogous to the speed of causality. The faster the speed, the shorter the movie. If the speed were infinite, it would no longer be a movie. It'd just be a photo. Time exists because there is a delay between something happening here and its effect being felt in another part of the universe i.e. effects cannot propagate instantaneously. This inability is what is manifested as the speed limit of causality. Light just happens to be one of the things that can travel at this speed. This is actually the essence of special relativity. I find it kind of sad that most people either don't understand this, or instead focus only on the math, without thinking about its implications, or origins.

@@Fae-Fey 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 😅

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.

With regards to the two options with the rope, I think that what happens is the molecules become increasingly randomized until they are no longer predictable from the original path. You are applying a force to the rope, which adds mass and energy to the black hole causing it to expand. If you had an endless amount of material, you would see the black hole increase until it would eventually encapsulate yourself.

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

@@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.

For me to understand the extreme gravity of the black hole was visualizing it a little different than normal. Think of gravity not as lines in spacetime that curve downward, but of spacetime itself getting pulled into the massive object faster and faster the closer it gets - like a spillway on a dam. That's why light is slower near the black hole moving outward; it's not the light being pulled in, it's the spacetime that the light is moving through being pulled. So the light is moving at light speed through it's spacetime relative to it, but from our perspective it looks like it's moving slow because we are measuring based on our local spacetime, not from the light's spacetime reference. The event horizon is just when the speed that spacetime is being pulled at is faster than the speed of light, and that's why it seems like an empty pit from our perspective but from the perspective of someone going into the horizon they may not even notice. They are still moving at a constant or zero velocity through their own relative spacetime. Edit: Objects like the sun and the Earth without event horizons still pull spacetime inward toward themselves - you can ride along with this movement when you jump and feel as though you're being pulled back down to earth - as soon as you are in free fall (which is technically as soon as your feet leave the ground) the acceleration you feel is just the spacetime around you being pulled toward the Earth. Gravity doesn't only bend spacetime, it actually pulls it in toward itself. To where? I don't know. But objects like the Earth and Sun still pull it in, they just aren't massive enough to speed up the spacetime to faster than light speed which is why they don't have event horizons.

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.

You won't be frozen while in a black hole, you'll just move a lot slower then people on earth and that's the difference from being frozen. You will remain young by being in the black hole.

So if you had dropped it the top of the rod and the whole rest of the ride would collapse down into an infinite point. Just like if you dropped the slinky from high up the top collapses right down into the bottom part in the bottom part doesn't even move

I thought space and time becomes inverted inside a black hole, at least according to Penrose and other scientists. This led to the white hole hypothesis among other ideas. If that is the case, wouldn't that be a possible solution to the singularity problem (ie. the singularity is the point where space and time switch places)? Also, if time and space are inverted, how would that affect matter/energy? It's seriously mind bending stuff to ponder on.

They get closer and its multiplied again as they shrink. Eventually Jolyne has the idea to try and jump on the green baby because she "has to reach it at some point" but she continues to shrink without reaching it before being attacked by the baby's ability. Its virtually the same concept when you look at how the photon continued to slow down to a point that it looked like it wasn't moving.

That’s a good understanding but the theory is that time is relative, so with Einstein’s theory of relativity at hand, the idea is that your time comes to almost a complete stop inside the black hole to the view point of the people outside of it, but to you those people are so far in distance that they appear to be moving slow as well. What you are implying is that going into a black hole would be a form of time travel and you would be therefore living in the 5th dimension where the laws of time do not apply to you similar how in interstellar when they entered the black hole, his entire time line relative to him was laid out for him by the being living in the 5th dimension, in which case he had access to his entire time line and he was able to see the past and the future and the present was no longer a concept, the present would be wherever he chose.

@@jonathanplastow5220 if that is what you’re asking then the short answer is no. To explain you have to know what lies at the core of a black hole. And at the core of a black hole is condensed matter from the star that it was previously. When a star implodes on itself it doesn’t let its matter escape, what happens is there becomes an imbalance within the star where it is no longer able to support its self so the gravity of the star collapses forming a black hole, we do not have the technology to see something as small as the matter of the star at the center of the black hole, after all a black hole is one of the smallest known objects in the universe at its core. It’s gravitational pull on the other hand is massive. So knowing this about a black hole. If we had a telescope that could theoretically see past the blackness of a black hole and could see something that small, then we would simply just see the matter at the center of the black hole instead of a portal to another universe, because a black hole isn’t a rip in the space time continuum like many people think. It simply warps space and time with its gravity similar to how huge planets do.
