Dope Tech Episode 2

<<@its_notalex says : a black hole would emerge>> <<@Jack-O_hedgehog says : i have a thought about how portals would work with gravity i imagine a pair of portals, where one of them is rotated upsidedown, and are close to something with plenty mass, such as earth if we placed a smaller object in the middle of the portals, would the object begin spinning?>> <<@MynameisnotGraey says : 3:18 this treats portals like physical objects, which they’re not. The cube crumples because there is nothing else for its cohesion to do but interact with itself.>> <<@MynameisnotGraey says : 3:08 portals have no weight, they are rends in spacetime anchored to certain objects.>> <<@MynameisnotGraey says : 3:11 portals are not actually pushing anything. For any confusion, see what happens if you did this but on a spherical geometry instead of with portals. Would it extend spacetime or get locked in place? What would happen if you contracted spacetime? Would spacetime get bigger if you shrunk it while an object was in it?>> <<@MynameisnotGraey says : 1:49 really, this just illustrates the ridiculousness of your answer to the portal paradox.>> <<@rapture2819 says : I feel like portals are essentially a hole leading to another area. Since they are “just” a hole I think that if you smushed something between two of them, regardless of the objects rigidness it would be compressed infinitely small and become a singularity, creating a black hole. What would a black hole inside two smushed portals look like, I have no idea.>> <<@freemanc6258 says : You can’t move portals (quantum tunnels). Lol>> <<@megamihestia4049 says : if you think about it, this implies that you would encounter a resistence when trying to move a portal, and that resistence is porportional to the speed and the mass of whatever is currently going through your portal, since you are imparting momentum onto whatever is moving through the portal so that it can shoot out the other end>> <<@lundylow says : Now you got me wondering what happens if a person changes their velocity while passing through a stationary portal, if the same physics apply as a moving portal. If you change your mind and quickly stop and turn around mid-portal, are you risking tearing your body in half?>> <<@ThatBeTheQuestion says : I think your conclusion on Paradox 1 is close but incorrect. Material properties for sure play a part in the result (i.e. weak vs. strong material tearing itself apart or not), but if your assumption that a cube moving toward a portal at a given speed is functionally identical to a portal moving toward a cube at a given speed, then I think what would happen if a portal moving toward a cube and stopping part of the way through would more have to do with the mass/weight distribution of the cube. I think the cube would only move if the mass that had passed through the portal was greater than the mass that was still in its original location. Assuming perfectly evenly distributed mass (it might be more appropriate to use a sphere under that assumption), if the portal were to stop a quarter of the way through the sphere, then the three quarters mass greatly outweighs the one quarter that had passed through, and as such, that one quarter would not be able to exert enough force on the remaining portion of the sphere to get it to move. If, however, the portal moved three quarters of the way through the sphere, well then you've got three quarters of the evenly distributed mass of the sphere experiencing acceleration, and therefore easily enough force to drag the remaining one quarter along with it. Of course, having to drag the remaining one quarter along with it would would be a parasitic loss, and thus I think your conclusion is correct that the sphere would not move at full speed.>> <<@PassportBrosBusinessClass says : This is the reason why portals don’t exist. They violate all of the laws of thermodynamics.>> <<@-Ashyl- says : so, if you think about it, the kinetic energy is in the moving portal, NOT the cube. so either way the cube will retain low to no KE.. if the portal were moving and the cube passed through, it might simply just fall through the other portal? its kind of like an escalator, once you reach the other side you have more potential energy than kinetic energy so speed would stay the same... But hey, I'm no physics professor and the whole thing is still theoretical so what do i know..>> <<@toastedclubsandwich says : Pordle>> <<@Hackerplays-o9j says : If you think about it when you sandwich a cube the front part of the cube pushes the back part, as it carries the momentum the cube should theorecaly accelarate until both portals are cube length -1 apart from each other when they get to that given point considering that this portals dont contain mass the cubes atom will instantly shrink because of the force made by the cube it self however if the portals were to have mass the cube cuold somehow fill in that mass making the limit distance before shrinking cube length+ mass -1 and we would be stuck in the same loop but its just a theory>> <<@BigJimbo7 says : If the piston extended and hit the back of itself would it float or fall to the bottom of the portal>> <<@darkkillerx29 says : If physics has taught me anything it’s that the most logical answer is the most wrong answer>> <<@Jayden-e5l-l7n says : A>> <<@Roge_1 says : I think valve is just waiting for all the paradoxes to be solved so they can make portal 3 as difficult as possible>> <<@Hex4Ter says : according to the newset GR-compliance simulations, accelerating portals generate gravity, and portals don't care how strong your titanium rods are, they _will_ snap and crumble>> <<@Apk7gm says : If portal is stopped half way it won't suck in the box, the same way if we stop the box halfway while putting ot in, it won't get sucked in. Two portals colliding the box will just stop like when we try to squeeze a box with two hands.>> <<@snarfbot says : obviously b. didn't watch.>> <<@MRcheese14u says : If a cube gets inbetween 2 portals and the portal are an unmovable object it'll get crushes by it self an infinite amount of times so it would always crumple>> <<@-inFinity05- says : The portals definitely just stop if the box is strong enough to resist crumpling.>> <<@-inFinity05- says : The box is a solid object, and if the any part of me is moving forward at any significant speed, the rest of me is definitely just getting pulled in whatever direction it’s going, so I think it goes, but slower because it has to drag the rest of itself.>> <<@JLDomino274 says : 3:43 - maybe they didn't put it in the game is because they couldn't figure out how it's meant to work.>> <<@Oscar_Ozzy says : Well, technically portals don’t have a surface 2:53>> <<@nerine4188 says : I watched the video about portal entertaining another portal.>> <<@6n-thorus945 says : The answer is : its impossible to move one portal without moving another,>> <<@beardbird8 says : I disagree with your answer for paradox 1#, because if you think about it, it's the same as the cube going towards the portal and stopping half way through, which would just be the same as a object moving, and then not (but with a bit of space warping).>> <<@johnperic6860 says : so do portals have mass>> <<@SalimYahaya-j1f says : what if i go into a portal in a portal🤔🤔🤔>> <<@are_you_serious_88 says : amazing>> <<@Gimmickvr says : It wouldn’t make sense for it to break just like if we were moving the cube to the point halfway through>> <<@anti_gen says : This assumes that portals as physical objects, which i always took from the game that they arent. I understood theyre no different than worm holes and are just connections in space time. So your pushing away conclusion wouldnt hold, because there is nothing for the piston to push on. it would just push air and itself, never coming in contact with the portal. This applies to the first concept of running the portal into a cube. I dont think itd accelerate, it would remain stationary since nothing is in direct contact with the cube. It would be no different from passing a hula-hoop over the cube and it would just plot out on the other side.>> <<@nickv4937 says : portals are a way expensive alternative to both having monorail tracks obstruct catwalks, and it makes transport neatly quicker than before>> <<@creaturekaspar says : What if you strike the edges of a portal? Is it infinitely thin and will bisect any matter?>> <<@Continentalmunkey77 says : 1:11>> <<@EthanGates-yi6dy says : C if the portal is going dowen>> <<@WhatBananas says : Your an absolute genius. ❤>> <<@גיאדרי says : The game engine suggests there is something inside the portal>> <<@didisteev says : if you look at the portals as if they're wormholes,it whould be a bit easier i think.>> <<@Scyththemasked says : Idk if I'm right, I'm not saying I am, but I think this depends on what the portal actually is, if it somwhow mashes 2 different locations into one within in the portal or something like that, then your version would likely be the true one, and since we are talking about the game's portals, and this seems to be the case for them, then you would probably be right, but if we were to use a wormhole for example, and the transition between the 2 portals would be delayed, then I think that the object would simply be going through the path of the wormhole until the 2 portals are separated, if we assume that portals are just fancy teleportation, then I think that the whole 4th demention thing showcased in the guy's video may be the case, as you would be constantly deconstructed and reconstructed, but at the same time, you might just straight up die and be unable to see this 4th dimension-esqe possibility.>> <<@aidenk4990 says : 3:29 then isn’t that away to duplicate that>> <<@reaganmonkey8 says : 3:57 “We don’t actually know how moving portals officially work.” Does that imply that only the portals in _Portal_ are the official way? Apparently any other interaction of portals just doesn’t exist.>> <<@AhryanCraft says : ok portals are not fictional because are Milky-way is technically a portal>> <<@AliceEnter says : Why can't the piston just push it's base until it reaches the portal, then exist from the other portal and so on?>> <<@janthran says : big disagree. the portals won't react, you'll simply crush the box because it'll resonate with itself instantly>> <<@graddy3470 says : I think the thing between portals get absolutely crushed. Better question is if 4 portals existed and we had 2 pairs, would they stay connected as they were if you overlap non pair one with other other pair?>> <<@CorbanDrake says : I’m highly offended how you made the dog looking creature see portals how I see them😞😞😞>>
