17:30 He's a _literal_ stick figure. i.e. an animation. Therefore, he's not even actually made of matter - he's basically a primitive physics object in a computer physics simulation that has been moved to the real world _unchanged._

[@riah9549]

I was wondering about that, even if being an animation wasn't taken into consideration any 2d "object" you can think of doesn't necessarily have matter, im not rlly good at this field tho lol

[@pokemonfanmario7694]

I personally headcanon that the AvA world is one where imagination can literally come to life - such as stick figures, video game characters, even graffiti and cave art! Its a 'Amazing world of Gumball' type situation. TSC is one case, and the maths and physics dimensions are another (the latter cases being representation of humanities understand of those fields, not theoretical true models.) Eventually those two dimensions will change as mankinds knowledge grows deeper.

[@SpecterNeverSpectator]

i dont think he moved to the real world unchanged, i think he is simply *inside* the simulations, hence why the planet is white and empty or heat and oxygen not accounted for, because this is a physics simulation.

18:38 Compact dimensions were explained to me like this: imagine an ant walking along a straw. The ant can move forward, back, left, or right. However, if you zoom way way out, the direction along the circumference of the straw is no longer noticeable, and it looks like the ant only goes forward or back. That small, circular dimension is called 'compact'.

[@tristangreenlee9272]

@SonaNerikovvv Not exactly. The moon appears to move slowly because its distance from Earth means that it subtends very small arcs per unit time when viewed from Earth, not because of compact motion. Imagine if the moon were lopsided and wobbled on its axis, by a kilometer or so. From Earth, you would need a telescope to see it, because a 1 km wobble is negligible compared to the distance between the Earth and the moon. The point of a compact dimension is that its size is negligible, not merely that it is difficult to see.

20:32 there wasnt any quantum entanglement with the rocket. He used closed strings to create the rocket himself and then sent that rocket through the wormhole. Same with the solar system, flashlight, apple that all of his past versions used. And as far as the hat trick near the star, stars absolutely have their own atmosphere(its how solar winds exist) but yes his hat wouldnt do anything, but it wasnt his hat that changed his velocity, it was him kicking the rocket away from the star giving him enough of an angle for his acceleration to slowly change his trajectory from a collision course to a slingshot. And at the very end he didnt go to another "universe" as it were, rather he completed the Causal Loop by returning to his own timeline. Edit: so he did go to another universe which means he avoided a Temporal Paradox by leaving the universe, which means the Causal Loop only exists for those that have yet to complete it.

Everything else is a real-ish thing made of real-ish particles that obey real-ish physics, but Orange is literally just a cartoon. So everything else is compressed until it can’t be compressed any further, but because Orange is a cartoon, he can be compressed further to the point that he’s smaller than the smallest particles in physics. …I think.

[@Time_Lantern_Gameplay]

According to what I read over 7 years ago. I heard entering the blackhole would crush something into an infinitesimal dot after spaghettification

[@cooly1234]

its actually an effect called Frame Dragging which would be noticeable near the inner horizon of a black hole. due to how the extreme gravity bends space time, objects appear bigger than they are. Now is that a 100% realistic depiction of frame dragging? ofc not.

[@pokemonfanmario7694]

Its because TSC is an imaginative concept of a flash stick figure. In flash you can resize objects - the black hole couldnt "crush" him like it did with the apple, but it could 'resize' him as its closest approximation. Fortunately, resizing an object in flash doesnt kill it.

These are the time stamps for actual video, in case you wanted to know more 0:21 Distance is the length between any two objects regardless the direction. 0:26 The arrow on his head represents vectors, Vector is a physical quantity that has a magnitude as well as direction. 0:30 Velocity is rate of change of displacement with respect to time or in simpler language, quantity that tells how fast and in what direction an object is moving. Velocity is a vector quantity as it has direction unlike speed which has just magnitude. 0:35 Unit of velocity is meter/second. 0:41 Displacement is the shortest distance between two objects. displacement can be equal to distance when walking in just one direction but never greater. 0:45 Average velocity is the total displacement/total time. 0:54 As he moves with an additional velocity and both the velocities are in the same direction they add up to give net velocity. 0:56 He speeds up or accelerates. Acceleration is the rate of change of velocity with respect to time or in simpler language/ the rate of speeding up. 1:04 As he falls he slows down due to acceleration caused by friction is in opposite to the direction that he is moving in. Friction is an electromagnetic force caused by the repulsion of electrons. It always opposes relative motion. 1:09 The stone falls due to the force of gravity. Gravity is caused by the curvature of 4 dimensional spacetime due to mass or energy or in simpler language, it is a force of attraction between every body that has mass. 1:10 The stone bounces due to its elasticity As it bounces it loses energy and hence velocity, therefore it bounces less every next time. 1:17 1 KG is the mass of the stone. Mass is the content of matter in a body.(The downward arrow should not have been there as mass has no direction, but weight being a sort of force that acts downwards has direction) 1:21 Force is a push or pull. We can get quantity of force by multiplying mass and acceleration. 1:24 He displaces the stone from its initial position through a force and does some work. Work is the dot product of force and displacement. force and displacement are both vectors but when their dot product is done we get a scalar(that has only magnitude). In simpler language work is force times displacement.(Work is also equal to energy) 1:25 The arrow below shows the force applies by the stone on the ground and the below one shows force applied by ground on stone, as every action has an equal and opposite reaction. 1:28 Work is done within some time, and power is required. Power is rate of change of work with respect to time. 1:30 The black arrow directed downwards shows the amount of force applied by the stone. The stone bounces at an angle with respect to the horizontal. F sin(theta) is the vertical component of force and F cos(theta) is the horizontal component of force. Vectors can be resolved into components, in simpler terms we can divide a vector into two or more vectors by defining certain directions. The vertical component keeps decreasing as gravity is acting downwards but the horizontal component remains the same as there is no acceleration in this direction. 1:34 He is able to stop due to friction. Mu(the symbol written above friction) is the coefficient of friction. It is a constant that can be different for different surfaces. 1:43 Friction is very less, so he cannot move as friction helps us in moving. 2:08 m is the mass of the stone and r is the length of the string. L is angular momentum which is mass times velocity times length. The velocity is always tangent(perpendicular) to the circular path made by the stone. 2:13 P is linear momentum which is mass times velocity. Linear momentum is the combined effect of mass and velocity in keeping a body in motion. 2:18 Refer to 2:13. He is moving forward due to linear momentum. 2:37 As he hit the ball, his momentum is transferred to the ball as momentum is conserved. 2:54 Kinetic energy is the energy that comes by the virtue of motion, if anything is moving it has kinetic energy. It can be calculated by multiplying mass by velocity squared and then dividing by 2. 2:56 Gravitational potential energy comes when you are at some height above the earth. It can be calculated by multiplying weight of the body by height at which it is. 3:04 The force in the string is tension force, it is kind of a force that gives measure of stretching of the string. 3:07 As energy is always conserved(neither created nor destroyed) the potential energy converts to kinetic energy as he slides, and once he is at the bottom the conversion reverses. 3:24 As he pushes himself he gets an extra boost, in other words extra kinetic energy. 3:29 Before landing he is in air for some time, that is due to extra kinetic energy. 3:54 As kinetic energy also depends on mass, the ball has more kinetic energy, therefore it goes a little more ahead. 4:01 Torque is the measure of force that can cause a body to rotate. As in linear kinetics force is what makes things move. In rotational mechanics torque does. It is the cross product of perpendicular distance and the force. Cross product is done between 2 vectors and it does give another vector. 4:16 He is continuously accelerating and at last he gets a final force which makes him go upwards. 4:21 He slowly escapes the curvature of spacetime or in simpler terms gravitational pull of the planet. 4:40 The rocket is pushing propelling due to thrust. And as we all know every action has an equal and opposite reaction. 5:08 Here comes special relativity. c is the speed of light and Gamma is the Lorentz factor. This factor is in almost every equation of special relativity. As velocity approaches c Gamma increases exponentially. 5:30 Speed of light. Almost equal to 300000 kilometer/second. 5:33 A wave front is an imaginary surface representing corresponding points of a wave that vibrate in unison. Light is neither a particle nor a wave. It is both. 5:35 Reflection of light. When light hits any surface it bounces off and scatters in other directions according to Snell's law. In the process it also loses some of its intensity. The angle with which it strikes the plane with respect to a normal is equal to the angle with which it bounces off. 5:37 He is changing the wavelength of light and hence the colors of the rainbow. Wavelength is the length of an individual wave. You can imagine this by thinking of a water wave. 5:39 He goes beyond the visible spectrum. Our eyes can only see certain frequencies. 5:41 Now he went below the visible spectrum. 5:53 He is pulled by the planet's gravity. 5:58 He pulls off a gravity assist. As he moves around the planet a little bit of planet's momentum is stolen by the rocket and hence increasing its velocity. 6:32 His velocity was directed toward the star, and now he is stealing the star's momentum(though a little).

[@Universon-wi7mx]

7:16 He is moving with the rocket even though he is not on it as, as he jumps his velocity is equal to the rocket's velocity. He is not slowing down because there is nothing to stop him. This is due to inertia, it is the tendency of a body to continue its state of motion until and unless an external force is applied on it. 7:23 Magnetic field is simply a field in which a magnet can express its power. Mu here is the permeability of free space, its different for different media. Magnetic and electric forces are interconnected. In fact light is an electromagnetic radiation. 7:25 The rocket is made of some magnetic material, and the magnet applies a force to it, and the rocket gets pulled. 7:40 The disc is made of a magnetic. Magnetic flux is the number of field lines passing through a closed surface. 7:48 This stickman knows stuff!!! He is magnetizing the rod. 7:52 He is making a solenoid. It is any closed magnetic material wire or loop. He loops it around the rocket as it is made up of metal and it magnetizes the rocket. 8:16 The velocity of a magnet when passed through high magnetic flux density increases. 8:27 Gamma is increasing due to increase in velocity. 8:38 A star system is a collection of star having planets revolving around it or even another star. 8:39 Asteroid fields are area of space having high density of asteroids. 8:40 Comet is a sort of snowball made of frozen dust, gases, ice that orbit a star. 8:40 A nebula is a cloud of dust and gas that acts as a stellar nursery. Some nebulae are made up of gases thrown out by dying stars. 8:44 Time dilation is the slowing down of time for the moving observer. Time for him runs absolutely fine but according to him time is faster for the stationary observers. On the contrary time for stationary observers is moving fine but according to them it has gotten slower for the moving observer. It has been experimentally proven, The thinking of Einstein. In simpler terms time dilation is the moving of time differently for observers in different states of motion. He is experiencing it now as his Lorentz factor is increasing, way more than it does in normal conditions. 8:47 Space dilation, also known as length contraction. The moving observer's length is contracted as seen by the stationary observer. Again it is a matter of perspective. The faster you move the more contracted you will get. 8:55 Spiral galaxy is just about the shape. Quasars though are galaxies that have a black hole at their center that's accretion disc is ejecting X Rays, etc.(it is believed almost every galaxy has a super massive black hole at their center) 9:04 The light bouncing back off him is getting red shifted meaning it is shifting to longer wavelengths due to doppler effect.(This can be experienced with car horns) 9:09 The black hole. It is formed when a star having mass more than 2 times mass of the sun collapses under its own gravity due to running out of gases. It is surrounded by an accretion disc of stuff that it has attracted and is slowly consuming. The relativistic jet is the one I talked about in 8:55. 9:26 Near a black hole, the gravity is immense. That is why Gamma is increasing so quickly. Being in a gravitational field is just like having some acceleration. And having an acceleration means increasing velocity and hence Gamma increasing. 9:31 Event horizon is the point of no return. You touch it, goodbye. Singularity is believed to be the point where all the matter from the dying star is gathered. It has no volume, hence infinite density. Near the black hole, the disk spins so fast that an effect of Einstein's theory of relativity becomes apparent. Light streaming from the part of the disk spinning toward us becomes brighter and bluer, while light from the side the disk rotating away from us becomes dimmer and redder. This is doppler beaming. A photon ring is a thin circle of light caused by photons that have grazed the black hole so closely their paths are deflected directly toward us. 9:34 That is Hawking radiation. Black holes do emit radiation. Empty space is not empty, it is full of virtual particles, coming into existence and annihilating each other. If this happens near the event horizon of a black hole one of the particles may fall in and the other is ejected outwards. To a far off observer it would appear as if the black hole emitted radiation. 9:56 As light leaves the high gravitational field surrounding the black hole and reaches the observer who is in a lower gravitational field it loses energy. So, because light becomes more red at lower energies, the object seems to get redder and redder as it approaches the event horizon and finally just disappears. Actually if you were to see anyone fall in the black hole you would never see him falling in. 10:24 Gravitational pulse is a ripple in spacetime, We recently detected it in experiment. 10:51 He is getting spaghettified as the gravitational pull on his feet is way more than that on his head. 11:03 There are several layers of the event horizon itself. 11:10 Biology, I don't feel like explaining it. 11:23 Hydrogen bond is sort of an intramolecular bond that forms between hydrogen and an electronegative element. 11:24 Electron orbital is where electrons revolve around the nucleus. 11:25 Protons are positively charged baryon that consists of two up quark and one down quark. 11:27 Every particle has its antiparticle pair, when they meet they annihilate releasing energy. 11:30 Neutrinos are really light particles that interact with matter very little. 11:36 String theory. World sheet is a two dimensional manifold(shape) which describes the embedding of a string in spacetime. 11:41 Anti de Sitter space are the exact solutions of the Einstein field equations for an empty universe with a positive, zero, or negative cosmological constant, respectively. 11:49 Refer to 9:41. 11:46 A possible theory that black holes are gateways to other universes. Watch Veritasium's latest black hole video if you are interested. 12:15 Quantum mechanical effects are being undertaken. The probability waves give the probability of finding him there. 12:28 Possibilities. Interstellar! 12:47 In string theory Calabi Yau space is a manifold that has more than the three familiar space dimensions. It has 6 curled up dimensions which are necessary for string theory to work. The 3 holes represent 3 families of particles in standard model of particle physics. 13:09 Hyperbolic space of dimension n is the unique simply connected, n-dimensional Riemannian manifold of constant sectional curvature equal to −1. 13:10 Einstein Rosen bridge is a kind of wormhole that acts as a shortcut between regions of space that are far apart. 13:16 Now that is inspired from interstellar. 13:41 Two types of string in string theory. 14:11 Tipler cylinder was discovered as a solution to the equations of general relativity. 14:55 He is the Creator. 15:36 Six types of string theory. We started from distance and now have come to string theory, My God!

There's not a truly "stand alone" video unrelated to the narrative as a whole anywhere in his catalog of work that he's publicly shared anywhere. There's even a video showing that every "short" took place while other events were happening. The president for it to be a "true statement" has already been set by Allen from the start. In a Narrative sense,It's a complete logical conclusion to make considering all last evidence presented by the pacing and structure of the whole narrative thus far and no further. 😗I simplified my statement before with some dramatization in order to drive viewership and interest over to Allen's overall work. He deserves it for his mastery of his Craft. 😮‍💨 Further more... 🙄It's far less "Head Cannon" than it is a Logical conclusion to reach based on all patterns presented in Allen's creative methodology. 😗This being only slightly different from a "fan theory" in that I'm not trying to predict his next move or story beat.

Basically he began to shrink and entered increasingly smaller and smaller spaces - first the stem of the apple, then its stem's cells, then the Chromasome of the apple cell, then the DNA, then a hydrogen atom, shrinking all the way down to the planck length (the 'lowest limit' of space. Think of a pixel where it always has a set size. Now apply it to real space.) The space at a planck length is so tiny that basically all models (our 'approximated understamding') of physics break down.

It's worth noting that hawking radiation isn't really virtual particles, that's just an oversimplification. It's actually Unruh radiation caused by the horizon creating a different perspective for observers on the inside vs the outside. From an outside perspective, equilibrium in such extreme gravitational field would mathematically require energy emission in the infrared wavelength to be in balance between the infalling sublight velocity (timelike interval) curvature and the horizon's light velocity (lightlike interval) curvature. This is reversed from the interior perspective of an event horizon with its spacelike interval, resulting in net reduction in energy from effectively destructive interference. Since mass is an emergent property of energy, that effectively means a net reduction in internal mass and a net increase in external mass from the energy carried by the infrared radiation. That's why it's always a one-way effect unlike the virtual particle oversimplification which would have no way to differentiate when taking in a particle vs an antiparticle. That's also why it radiates more rapidly as the black hole gets smaller. The event horizon has a smaller radius, increasing the horizon's curvature so that the balancing value is greater and it continues to radiate faster until the Schwarzschild radius is too small. What "too small" means is not settled yet. One argument is that it's the point where the surface of the event horizon is smaller than the field of any particle it could emit. Another is that it's the point where it's smaller than the mass it contains, which likely means an individual particle.

[@SignalRaptor_]

at around 3:10 this shouldn't work. If the surface is near frictionless, throwing the object should propel TSC backwards an equal amount that it's pulled forward by the 1 kg sphere. and even if it did propel TSC forward for some reason, if the surface is near frictionless, why does it slow down almost immediately after the first throw? Shouldn't momentum be conserved at almost 100% efficiency?

While I’m only saying this on a fried physics brain and zero hours of sleep, I’d wager the rotational motion he did prior to throwing it did something for that. The precession that occurred while he was spinning it is a key thing in gyroscopes, because anything that’s spinning along an axis will absolutely hate being moved from that axis.

the funny thing is, we haven't measured the speed of light, we all just agree its 299,792,458 m/s for simplicity. there are two main problems when trying to measure Light. 1 without the speed of light we don't have a external definition of what a meter is, as all our measurement systems for distance is from the basis of the speed of light including our basis of time. 2. Time dilation, it is impossible to measure the speed of light because of the difference in time, even if the first problem is solved we can never get around this problem, no matter how accurately you can sync two clocks there will also be a Nano second delay of some time due to distance and other very complicated physics. and you can begin to solve problem 2 until first you solve 1.
