No one could possibly come up anything like this… ”Hey Einstein! You are wrong. Look at the symmetries. There aren’t any that means energy is leaking through the cracks to other dimension.”>> <<@wiecek00 says : It would be nice if you learned how to pronounce "another" 👍>> <<@bigdogboos1 says : if you lose energy in the "cracks" of the bending spacetime, then with certainty if you were at those specific places you'd see the same thing. It does not disappear if you narrow into it. The same way relativity is huge near black holes and neutron stars etc, but imperceptible here on earth ... but it's not 0. This energy drain should be measurable if it's a reality.>> <<@GafletDalaletHattaHiyanetteler says : I guess you just missunderstand previously...>> <<@slackerman9758 says : Not sure if this was addressed, but in accounting for gravitational potential energy, the net energy of the Universe can be zero.>> <<@hopetulovemi says : OK I know its only 18 minutes in, pero, I have to wonder if it is not energy but time that is not conserved as the universe is expanding our point of reference seems to see that the object accelerates when it is the light that is slowing down as time from its point of reference far in the future compaired to our referance point slowes down. If energy is conserved and we are currently on the expansion slope of the universe then it would appear to us if everything is moving away and in the dark cold late history of everything it would appear as if everything is shrinking and time is the culprit again the motion is consistent the energy is consistent its time that is variable and our perspective of everything else lenses it to seem that motion is accelerating or decelerating everything away from us.>> <<@philipberger9452 says : 3:34 and what about the symmetry mirror at the borders? They even move the object :) .>> <<@LinkHobbs says : Just started watching and the intro is a little off-putting because it doesn't say what the rock stopped relative to, but I will just ignore that and see where the video goes.>> <<@AdityaSharma-o1r3z says : Can anybody ans that if we consider that we are in a largely empty area of universe far from any galaxies and take a Newton's craddle there and give it a nugde then as energy isn't conserved it should stop after a while but I wonder that what effect does anything expanding in our universe have on those balls and moreover why should energy not be conserved in that case?>> <<@home-powersystems7782 says : You have no idea what you are talking about.>> <<@TheRobGuard says : The misconception is that when people use up their cars gas (energy) they think its forever gone, but in reality it has just transformed into something else like heat, sound, etc. Energy is never destroyed just transformed and dissipated into other forms of energy, broken up into pieces, scattered around, etc.>> <<@HishamLa-lx9ef says : മക്കളെ സാനം 11:11 ..🤌🏼🗿📈💨>> <<@LaurentWeingart says : I may have a stupid question, but couldn’t this loss of energy be the dark energy that fuels the growth of the universe ?>> <<@zdenekbina6044 says : Experiments in one place can have different results in another place. 10:50 seems false assumption. We dont know other places in universe at all>> <<@NA-sb7xz says : They weren't wrong>> <<@anilsingh7225 says : Curiosity comes by birth 😊 Nazis were the most unfortunate thing happened to Germany 🇩🇪>> <<@flipped_bit says : Seriously, her name is “Noether”. Jerry, get out of your booth and fold yourself 12 times. You cheap insects f* didn’t think we’re worth your best equipment? We never left Shoney’s!>> <<@missanthrope2 says : 17:30 😮😮😮 so what causes these commets and meteors to keep zooming around???? in the illuminated either vacuum of space? 😮😮>> <<@timothysmith7888 says : So, why is your graphic of the rock hurtling through space, shaped like a circumcised phallus?>> <<@anthonyobrien3685 says : As an educational video this scores zero. Disjointed unexplained garbage>> <<@Sam-w6z3z says : Yeah well this just goes to prove the General Theory of Human Migration.>> <<@Sam-w6z3z says : The obvious response is that clearly life in space is fundamentally different from life on Earth but let's ignore that obvious point for the sake of the story development. But clearly this tendency drove a number of people to insane levels of hate for Jews.>> <<@KemeiJoshua-ee4ih says : The universe is designed to conserve energy guys, it is no misconception. Do we even really understand energy.Nevertheless I beg anyone watching this video not to take the "big bang" perspective of the universe,you will be forever fooled.>> <<@almcdonald8676 says : I’m a real maths dummy but it seems that you summed up Emmi Noethers contribution to physics as telling hilbert that the bianci equations he dismissed would have to do as there wasn’t anything better, which I think is down to my failure to appreciate the complexities of the reasoning rather than your excellent explanations. This really is a very very good channel>> <<@baxtermullins1842 says : The rock is in a gravitational field! Energy is conserved!>> <<@sirrisaa1807 says : so energy isnt conserved>> <<@planmet says : The rock slows down and loses energy to particles of dark matter that it collides with. Those dark matter particles gain energy from the collisions and so there is an overall conservation of energy.>> <<@Highley1958 says : Seems to me if there is more mass behind you than ahead of you, you'd slow down and eventually change direction.>> <<@kiksonmartinec9656 says : So the space will eventualy get out of the energy??energy will wanish??>> <<@kam6642 says : The way I stay locked into the math portions of these vids like they make any sense to me 😭>> <<@33Tesla33 says : These egg heads over think the simplest things. Good grief, what nerds.>> <<@philipparsons says : The video’s opening scene is misleading because it implies the rock slows down relative to the astronaut, which is false. The rock only “comes to rest” relative to the cosmic expansion frame, which the video does not clarify until much later — and even then, only implicitly.>> <<@roadyholmes says : i actually follow the translation symmetry. The partial derivatives i haven't handled in awhile and unused knowledge gets more remote w/time. But, i have books and we not so dependent on memory anymore.>> <<@TheBinaryUniverse says : 17.30 - Wrong! Dark Energy is the increasing frequency of time, the increasing rate of time. The universe is expanding simply because the time rate is increasing. You cannot have space without time, and you cannot have spatial expansion without temporal increase. Time rate increase always follows the Schwarzschild metric as you move away from a region of zero time rate. This must also apply to duration as well as to distance. So, simply change the horizontal axis on the Schwarzschild graph from distance to time duration, and you have the the way the universe has been increasing in time rate from the big bang, and therefore getting bigger. This graph gives us the initial "inflation" in the early universe, and the residual "expansion" we observe today. For the decelerating rock, it simply loses kinetic energy because the energy field it gets its kinetic energy from, is running down, like a spinning coin increasing in frequency but losing energy. This is a purely relative loss of energy compared with different times in the life of the universe. If you were to travel to a future where the rock had lost energy "e". you would measure its energy as the same as it was earlier. It has not changed in reality, only relatively over time. The laws of physics do not change over time and energy is always conserved. Mathematics only gets you so far, but like a blind man with his "stick" of mathematics, he only sees the reality when he opens his eyes. It take imagination and ideas to make real progress, not just math'.>> <<@SampleroftheMultiverse says : The distance traveled through space time by a particle is conserved.>> <<@jayburbs15 says : All this proves is the stock market is useless.>> <<@eric4709 says : If the.rock stops.. that implies 0 velocity.. but.. relative to what??>> <<@Truthsetsyoufree100 says : If there are symmetries across reference frames could space time warping not mean that an appearance of energy leaking not be energy conserved but translated? Doesnt this account for what was said about it being part of gravitational change of the universe?>> <<@arunkumarmn7493 says : Oh man! That's a lot of mathematics😓>> <<@Chanpreetsingh-u4f says : but why don't we concider other forces acting on that photon like gravity and heat that cancel the energy of that photon>> <<@angonkonyak7240 says : If every universe is expanding then why light not what make it different>> <<@johnnorris1983 says : Energy is transformed through a perpetual entropy process within molecular equilibrium. Visual constraints choose us to see a problem as a whole. Where things tend towards zero but can’t>> <<@dragonzdrool says : Energy is expended period, this is like middle school knowledge>> <<@Asatheace1 says : So basically the end of the day she ended up using Einstein‘s equation lol… wow what a genius>> <<@williamscott6291 says : The conservation of energy is real so I don't know what they are talking about here.>> <<@WhileTrueCode says : i fink i would prefer out of all da presenters, you only select dose dat have learned how to make der mouth able to pronounce TH>> <<@haroldwestrich3312 says : In terms of Deep physics thinking - "Creating the key that unlocks the door; does not imply understanding how the lock works nor what is behind the door"! Based on this idea; I believe humans have figured out how to "Make the keys" for most physics puzzles; but seldom dive deep enough to unravel exactly how "The locks work".>> <<@PRIME.ACCOUNT says : my brain hurts a lots to thi😭😭😭>>
