Here's a question I've seen a lot in comments: OK, I'm accelerating up but then shouldn't someone on the other side of the globe fall off? No, here's why: Either watch again from 8:28 or read what I've written below... Spacetime is curved - it curves the opposite direction on the other side of the Earth. Neither us on this side of the Earth nor they on the other side are changing our spacial coordinates - we're not moving up, they're not moving down - Earth isn't flying into one of us. BUT we both ARE accelerating. In curved spacetime you have to accelerate just to remain stationary. The traditional definition of acceleration is something changing its velocity. In general relativity you have to embrace a new definition of acceleration: it means deviating from a geodesic - not going on a straight line path through spacetime. Near the Earth a geodesic is a parabola so unless you're moving in a parabolic arc (like on a zero-g plane) you are accelerating. This definition is the same as the old one so if you're accelerating in deep space then your velocity is changing. *BUT*... if you are near a large mass you are in curved spacetime, now acceleration your velocity is changing. You can stay stationary relative to Earth's surface and still be accelerating. This is because your acceleration should be measured not relative to the Earth's surface but relative to free-falling objects - they are inertial observers. Imagine this - I'm in deep space and I make horizontal rows and rows of stationary golf balls. Then I hop in my rocket and accelerate up through them. Just think about what that looks like. Now my rocket is back on Earth just sitting there. I freeze time for a sec and make horizontal rows and rows of golf balls up into the atmosphere. Now unfreeze time. What do you see? If you just look at the golf balls and the rocket ship it looks the same as the situation in space where the golf balls were stationary and the rocket was accelerating. Einstein's point was the golf balls have the better claim as the "stationary" thing since their experience is just like the golf balls in deep space - no forces experienced. The rocket on Earth is just like the rocket in space. It feels a force and hence an acceleration.

@Veritasium "In curved space time you have to accelerate just to remain stationary" Seems more like physicists have become so enthralled by these mathematical equations they are willing to throw out observable reality for them. I have two options, I can either call a lack of motion "acceleration" (which contradicts the clear definition of the term) or question the math / model I'm using to describe the physical world.

As a stem cell researcher I've recently read about studies investigating why organisms need gravity to develop and would have great difficulties in spaceships. Early attempts of growing plants in spaceships failed since plants need gravity for their root development. However, even single cells need gravity for molecular processes. For example, the cytoskeleton (which help cells to maintain their shapes) and several protein families have been shown to be affected by the absence of gravity (it would actually be funny to make a video about that myself). Great video as always!

*As a Harvard Neuroscientist, here's another mind-bending thought. When you rotate your head, you are NOT in control of the primary directionality of your eye movements.* Try this. Keep your head still and look at your finger while you shake your finger left and right; your finger will look blurry due to motion blur. Now, instead, keep your finger still and look at it while you simultaneously shake your head left and right, which will demonstrate - in this situation - that you are still able to maintain a stable image of your finger. This is because your sense of your head in space - your vestibular system - has a hardwired reflex to move your eyes in the opposite direction of your rotational head movements. This vestibular-ocular reflex (VOR) ensures automatic dynamic stabilization of images during head movements. You are not consciously doing this, and you can not consciously override it. The VOR is truly a reflex and, interestingly, does not depend on vision. During head movements, you will still have a strong VOR if you are in the dark or if you have your eyes closed. Your VOR originates from your vestibular system, which is located in your inner ear right next to your cochlea - your organ of hearing. Your vestibular system for rotational head movements consists of a series of three fluid-filled semicircular canals that have little "hair" cells inside the canals. When your head moves up-down (pitch), left-right (yaw), or shoulder-to-shoulder (roll), fluid inside the corresponding semicircular canal flows. This head motion-induced flow bends the hair cells within the canal to ultimately send electrical impulses to your hindbrain. These electrical impulses - encoding head movement - then talk to parts of your brain controlling eye movements, which connect to your eye muscles to reflexively move your eyes in the opposite direction of your head movement. So be thankful that your sense of your head in space - your vestibular system - takes care of maintaining a stable image of the world even when your head bobs around as you walk. Otherwise, walking would be a blurry journey of craziness. Videos coming soon.

Great condensed delivery of information, as always. A few points of clarification that might be of help to viewers of this great video (and great channel): 1.) Based on general relativity, the question isn't one of whether or not gravity is an illusion. Rather, what we have, as you pointed out, is an exact one-to-one isomorphism between gravity and acceleration. So acceleration is just as much an illusion as gravity. We have to approach this from both directions. That is, bodies in a "gravitational field" can be thought of as accelerating bodies, as you've illustrated so well here, but accelerating bodies can also be thought of as bodies within a gravitational field. It works both ways. Acceleration and gravity are two useful ways of thinking that Einstein's theory reveals as equivalent. We could say that when we think we're experiencing gravity, we're actually experiencing acceleration, but we could just as easily say the opposite. The true illusion isn't one or the other -- gravity or acceleration; rather, the true illusion is the notion that gravity and acceleration are two different phenomena. Einstein shows us that the same thing is happening in both cases. 2.) Still, the claim that gravity is not a force isn't so easily made. Based on general relativity, it is a true statement, yes. General relativity shows us that gravity is not actually a force at all, but rather the motion of bodies through the curvature of spacetime. However, general relativity is not our only valid theory of reality. In quantum mechanics -- or, more specifically, in the standard model of particle physics, based on quantum field theory -- gravity is, indeed, a force. And we first detected gravitational waves in 2016, I believe -- several years before the release of this video, showing us pretty conclusively that gravity is, after all, a force (though no one has detected a graviton as yet, and likely never will). This is, of course, one of the many, many, many contradictions between quantum mechanics and general relativity tormenting physicists. Einstein's model is so aesthetically pleasing -- compelling, even -- it's only natural to want to believe it. But quantum mechanics tells us something else. As we know, the search for a super theory that unifies these two theories -- that is, the search for the theory of quantum gravity (or, at this point, I should say, the search for the correct theory of quantum gravity) -- is ongoing and should provide us with an answer to which of these theories is correct on the issue of gravity as a force. That said, that's probably not the right way to think about the problem. With acceleration and gravity, Einstein showed us that it wasn't about one being right and the other being wrong; it was about an equivalency -- a synthesis that allowed us to see both phenomena as facets of a larger conceptual structure, a structure in which the two phenomena are actually one. We should expect something similar from quantum gravity. The history of science is, if nothing else, a history of these kinds of syntheses of what previously appeared to be opposing, or at least separate, ideas, going back to electricity and magnetism and beyond. The fact that quantum mechanics is telling us that gravity is a force and general relativity is telling us that gravity is not a force should be a smoking gun that the entire question of whether or not gravity is a force is simply not the right question to ask. Quantum gravity, whenever it is established, will likely offer us a larger conceptual structure through which to understand these ideas, so that this apparent contradiction is resolved, much in the same way general relativity itself presented us with a larger conceptual structure through which we could understand the equivalence of gravity and acceleration, or the way special relativity presented us with a larger structure through which we could understand the equivalence of mass and energy, or the way Newton's theory of gravity gave us a larger structure through which we came to understand the equivalence of the heavenly and earthly realms -- that is, that the same laws were governing both -- an idea that would have been beyond foreign to Aristotle, and many who came long after him. In short, we can't simply state that gravity isn't a force, because quantum mechanics refutes that idea. Nor can we simply state that gravity is a force, because general relativity refutes that idea. And, of course, quantum mechanics and general relativity refute each other. And so we await the synthesis. It is one of a thousand key places in contemporary physics/cosmology where we hope quantum gravity will give us answers. Or, more realistically, lead us to ask better questions.

Gravity doesn't exist as was shown by the hammer and feather drop tests. Both here and on the moon. How can your physics be valid if it's based on something that doesn't exist? A force so weak it can't be detected and yet it holds galaxies together? Don't piss on me and tell me it's raining. What is the Higgs Boson? An electrical charge? There's your 'gravity'. It's why grains of dust coalesced in space. When you worship at the alter of relativity, you become blind to reality. You see things backwards. How is it that relativitists believe that mass increases with acceleration and yet hot water as less mass than cold? How is it that relativitists believe time slows down with acceleration in space when objects accelerated in space are actually losing mass? And how is it that relativitists believe that Newton's apple falling from the tree is the result of gravity? But rather it's impact with the ground is because of 'gravity'. You will never find the gravition because gravity doesn't exist. Which means your theories based on gravity are baseless. But you have to keep the house of cards from falling down so let's start warping the cards. How much more proof do you need to at least acknowledge that the earth isn't 'flat'.

Great comment! As far as I understand, general relativity is really just a mathematical description (with excellent predictive power) which does not attempt to explain why nature works like it predicts. It posits a bending of space and time, but it does not explain the mechanism by which mass/energy causes this bending. To me this seems to be a very weak basis for claiming that "gravity is not a force". General relativity just happens to give a mathematical framework in which gravitational phenomena are explained without there being a true force. (What I have been wondering about for some time is whether the Einstein field equations allow for an interpretation in which gravity is a "true" attractive force. I do not know the answer.) Regarding Derek's video, I think Derek has come up with some arguments pro general relativity which aren't as strong as he seems to think: 1. That you "don't feel" acceleration if you are falling through space and bending towards a planet is not because gravity "is not a force". Gravity as a force pulls at each of the molecules of your body in exactly the same way, which is why you cannot feel it, and an accelerometer cannot measure it. (So if we ever build an interstellar spaceship that reaches near lightspeed or beyond, we should do it in such a way that every molecule of the ship and what is inside of it undergoes the same force. Even more ideally, there would be a 1g difference in acceleration, but now I am asking for too much.) 2. While general relativity removes the question why inertial mass = gravitational mass, it raises the question why it is inertial mass that determines curving of spacetime. It just shifts the question without explaining anything. (At least in my understanding.)

@ronald3836 The simple answer to your questions is that mass has no force without acceleration. Mass is not the cause of acceleration but the result of acceleration. Or, more precisely, deceleration. As the atom's acceleration factor decreases, its mass increases. E=mc. Mass is stored energy unlocked by acceleration. Mass is inert. It has no functional properties other than length width, height. Gravity is the result of an external force accelerating the frame of reference. What you feel is that applied force accelerating you in space. The same as dipping your hand in hot water. You feel the water molecules being accelerated. The earth is round (curved space) because F=ma. Force equals Acceleration. As the acceleration factor increases, the mass factor decreases. Which is why the atmosphere becomes thinner as the radius increases. Because the earth is rotating on its axis, it's mass is being accelerated not only outward but forward as well creating curved space. The 'gravity as a force' math works because framing mass as the force multiplier creates a mirror image from reality. Mass based Relativity says the atmosphere thins because there is less gravitational attraction. In reality, the laws of motion show that the atmosphere becomes less dense because of acceleration. Which one are you going to believe? Newton's Laws of Motion that accurately describe the Earth, its atmosphere, its tides. Or some made-up mathemagical theory that doesn't hold water? What does Relativity give you? An increase in mass with acceleration? Then why does cold water have more mass than hot water? Time-dilation? Then why do astronauts experience accelerated heart rates and solar sails increase in temperature? Gravitational Attraction? Why do objects with disparate mass attributes fall at age same rate? Gravity is one frame of reference being accelerated by another frame of reference. When standing in line and I push you forward, what you feel is gravity accelerating you. When you accelerate yourself, take a step forward, you don't feel gravity. Here is something for you to ponder regarding gravity. The Earth's rotation speed currently creates a force of 1g. If the Earth's rotation doubles, it would create a 2g force. What would happen if the Earth's orbital speed around the sun where to double instead. Would you still be subjected to the 1g force as generated by the earths rotation?

@@ronald3836 To be fair, no theory in sciences will answer the question why nature works like predicted. It is a question that isn't asked within the scientific method, because the method is not fit to answer such kinds of questions. Science always will ask *how* nature works. The "why" is up to philosophs and other kinds of epistemological approaches. All we can hope from science is a deeper level of how all these natural laws work and how they are connected. "Just shifting the question" basically is the way of science. Every new theory will raise new questions. At least we know thanks to general relativity, that space is curved. That helps with looking for deeper answers.

Gravity is a force, or more precisely, it results from an imbalance in the transfer of forces by electromagnetic waves at the atomic level as a result of matter changing the properties of the structure of space. If it were just an illusion, we would not register gravitational waves; they wouldn't look for a graviton (which I think they'll never find); time dilation in the center of the earth, where gravity is not felt and light, according to Einstein's theory, travels in straight lines, would not be greater than on the earth's surface. Physicists should apologize to Lorentz's ether theory and thoroughly explain the mechanism of gravity, because Einstein's theory is only a mathematical theory that predicts results well, but does not explain the essence of the phenomenon.

As a Harvard Neuroscientist, here's another mind-bending gravity-related thought. When you rotate your head, you are NOT in control of the primary directionality of your eye movements under most circumstances. Try this. Keep your head still and look at your finger while you shake your finger left and right; your finger will look blurry due to motion blur. Now, instead, keep your finger still and look at it while you simultaneously shake your head left and right, which will demonstrate - in this situation - that you are still able to maintain a stable image of your finger. This is because your gravitationally-influenced sense of your head in space - your vestibular system - has a hardwired reflex to move your eyes in the opposite direction of your rotational head movements. This vestibular-ocular reflex (VOR) ensures automatic dynamic stabilization of images during head movements. You are not consciously doing this, and you can not consciously override it. The VOR is truly a reflex and, interestingly, does not depend on vision. During head movements, you will still have a strong VOR if you are in the dark or if you have your eyes closed. Your VOR originates from your vestibular system, which is located in your inner ear right next to your cochlea - your organ of hearing. Your vestibular system for rotational head movements consists of a series of three fluid-filled semicircular canals that have little "hair" cells inside the canals. When your head moves up-down (pitch), left-right (yaw), or shoulder-to-shoulder (roll), fluid inside the corresponding semicircular canal flows. This head motion-induced flow bends the hair cells within the canal to ultimately send electrical impulses to your hindbrain. These electrical impulses - encoding head movement - then talk to parts of your brain controlling eye movements, which connect to your eye muscles to reflexively move your eyes in the opposite direction of your head movement. So be thankful that your sense of your head in space - your vestibular system - takes care of maintaining a stable image of the world even when your head bobs around as you walk. Otherwise, walking would be a blurry journey of craziness. Videos coming soon.

I think it was a different way of living back then. From documentaries and audiobooks I've consumed over the last decade, one thing that kept surprising me was how young so many scientists of past eras were, AND, that they often made great contributions in multiple fields. There was no TV after school, evenings & weekends. It was a harder time for many and perhaps these chaps were more aware/grateful for their privileged education. I guess what I'm saying is people had less distractions with more motivation & time to move through the subjects. I think they were far better educated than us at equivalent ages - at least those who managed to get an education.

Now, this isn't to say our education system is perfect; it's anything but, to the point that allowing students to skip lectures and do literally anything else with their time raises GPAs by over 15% (twice that for students of colour). But we also know that IQ is, near as we can tell, purely a measure of socioeconomic factors like nutrition and education rather than anything genetic (yes, IQ is highly heritable, but lots of non-genetic things are inherited), and it keeps going up; people at a given age do still keep getting measurably smarter every year and every generation as long as they are given access to the shoulders of giants. Despite all our many problems and issues, we're still getting smarter faster than the problems we're faced with are growing more difficult. We could definitely be doing much, much better, but it's reassuring to know we at least aren't doing bad.

Here the guy is taking EVERY scenario thru the 'eyes' of SpaceTime. You can view these things he talks about thru other 'theories' also. What he's trying to get at here is there is no "Field", just Gravity.

You couldn't grasp it because their attempts to explain it are erroneous. Spacetime is a concept which fails to understand the primal force that creates the other forces. Einstein's error was in not understanding absolutes vs. relativity. Everything isn't relative, if it were, the speed of light wouldn't matter, but it does. There is an absolute by which you know that space is moving, and by that you can predict the movements of anything through space.

You are going to feel the same during the *initial* part of a fall, before you reach terminal velocity, as you would feel floating in space. But no fall in atmosphere is actually free fall -- there are other forces acting on you besides gravity. This why it feels very different to bungee jump compared to skydiving out of a flying airplane. When you are initially falling, you aren't accelerating relative to an inertial frame, and you can feel it. Your stomach "drops" when riding a roller coaster. Note, though, that this sensation feels very much like the sensation of being accelerated, like on a roller coaster that launches you. If you were falling long enough to reach terminal velocity, that sensation stops. You could try to make the situation between the guy falling and the guy looking out the window parallel, but there are absolutely measurable differences in their vestibular apparatuses. The guy falling knows he's falling. From a relativity standpoint, the guy on the ground is being accelerated up by 1 G and the guy falling isn't being accelerated, but practically the falling person can feel themselves being accelerated relative to the ground.

Nonlocality and "general" relativity is about the level of flat earthers, denying all science and energy conservation laws. How will one prove that space is a magical gelly of extra time or instant energy transfer? Gravity is an acceleration yes, because a force is the outcome (the field of) of particle charge due to spin states and vibratory conditions. Relativity is the opposite of anything general.. It is by being relativity, "special"(localities measured)

I dont understand the example with the light beam. If I'm in the frame of reference outside the rocket and see the rocket being accelerated, I unnderstand that I would be "seeing" a single photon traveling in a straight line. But as the light source is accelerated, I should still see the beam as curved. The depiction in the video seems incorrect. The light being emitted at time t1 at height x1 would not be at height h2>h1 at time t2 but still at h1.

Saying that gravity is an illusion and that it is simply a symptom of curvature of spacetime is a bit of an oversimplification. The truth is that we do not understand gravity. We can observe and predict the effects of gravity but we do not fully understand it which is why there is such a problem as soon as we go from macro to microcosmos of quantum physics and quantum gravity and why the idea of gravitons was proposed in the first place. Also, there is no such thing as being at rest outside of the effects of gravity. There is always some gravity well you would be in. Even if there was only one star in the entire universe and you were on the other side of the observable Universe, you would still be in the gravity well of that star, no matter how shallow it would be. The only reason we talk about escape velocity is that you manage to escape from a deeper gravity well into a more shallow one.

"Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=ma. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Consider the man who IS standing on what is THE EARTH/ground.

SO, objects fall at the SAME RATE (neglecting air resistance, of course); AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=ma. Moreover, the rotation of WHAT IS THE MOON matches it's revolution.

Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. Think. It ALL CLEARLY makes perfect sense. BALANCE AND completeness go hand in hand. Great !!! SO, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out EQUAL AREAS in equal times consistent WITH/AS E=MC2, F=ma, AND what is PERPETUAL MOTION; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. The stars AND PLANETS are POINTS in the night sky.

It always amazes me to read that gravity is not a force. That statement presupposes that the speaker knows what a force is. We might alternatively say , “one of these things is not like the others“ but then again, that assumes we know them both well enough make that claim. I suggest that there is no reason for the Universe to reinvent the wheel. No reason to complicate things by having two separate ways to manifest attraction or repulsion at a fundamental level. I suggest there is an underlying principle behind all supposed ‘forces’. If bending spacetime is the answer for one, then bending something else would be the answer for another. Of course gravity is a force! You probably don’t understand how forces operate in general.

CG space :) . But he did get to go on the Vomit Comet (when he was weightess).

unfortuently, he also crashed into a planet to explain it to us. R.I.P Veritarium 😢. You will be remembered

He didn't go to space. He went on a plane that moves in a wave (up/down) motion. When the plane goes down as fast as gravity's acceleration, then the people inside the plane feels weightless and are in freefall.

Flat-earthers: 'I should go research this' Heliocentrists: 'You see how stupid flat tards are?'. Makes you wonder who really honors 'science', doesn't it?

Why you gotta be so dishonest, "There is no gravity".... just curvatures in space-time that cause.... GRAVITY!!!!!

Finally someone calls out that ball and sheet analogy. That one pisses me off to no end. It never helped me get it as it never shows how it's not a force. You're just using what you're trying to disprove to prove otherwise.

"Gravity is not what you think" "Gravity is not a force" "You will understand everything about general relativity" "Gravity is an illusion" Now why gravity is not a force all the titles of this video that have been changed

My hypothesis is that Derek has a hypothesis about the YT algorithm and is testing it. My alternate hypothesis is that he already tested his hypothesis earlier and is now implementing a previously empirically validated optimization strategy.

The fact that he predicted most of my own questions with his white-shirt self made me feel surprisingly smart for noticing the "inconsistencies" before they were shown to me, thanks for the video man :D
