The General Theory of Relativity tells us gravity is not a force, gravitational fields don't exist. Objects tend to move on straight paths through curved spacetime. Thanks to Caséta by Lutron for sponsoring this video. Find out more at: www.lutron.com/veritasium

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.

Ok I get it. Everything in space moves uniformly in a straight line. When you get near a big object, say the earth, the curvature of spacetime makes the line bend towards it. Now suppose for a second you wouldn't crash into the earth's surface at that velocity, but instead just get stuck against it. Relative to your normal inertial path which would take you through earth, you are now being accelerated upwards. Stuck against the earth's surface like you're stuck against a magnet. Only a sufficient amount of thrust can get you out of that inertial path and into a new one.

Every time someone makes a comment about the beginning of the universe, They always start by saying "in the beginning there was a gravity field which attracted something else and then we had a big bang". I always wonder what existed before the gravity field? If you can imagine a gravity field then you should be able to imagine where it came from. I can easily imagine nothing but space, just empty space no time no gravity no mass nothing. How can so many come along and say we had mass and gravity when they cant explain where they came from?.

Honestly, if GR didn't have other independent predictions that have been proven correct, I think it'd just be a bunch of clever math. That Einstein took that one equivalence principle/thought experiment and just went nuts with it, but that it didn't actually apply to reality. However, its independent predictions have indeed been proven correct.
Jeff Kissinger
Jeff Kissinger Pred 4 urami
I’ve seen this claimed so many times, but it’s not true. All objects on Earth do not fall at the same rate. Your formula is missing m2. Objects fall at a rate of the ratio of each mass compared to Earth. While the ratios are a very small difference the principle that all objects fall at the same rate is false. If 2 objects the size of bowling balls were dropped at the same time but one had the mass of the moon they would not impact the Earth at the same time.

If massive objects creates space time curvature. I believe that every objects has their own curve spacetime too, it defends on the mass. What if the massive object like Earth is not accelerating but smaller mass objects and the Earth is pushing each other. The more massive objects, the more stronger push against bigger mass ( like Earth which is the center of mass of our world itself). Human has lesser mass than elephant so that it would feel heavier than us. All smaller objects around Earth including humans are pushing against Earth while Earth push upward everything around smaller mass object. In that case, no need acceleration just to feel our weight.

This episode makes me think of an episode of Futurama, where the professor was talking about the ships new cutting edge engines. He stated that the engines don't push the ship through space, but the ship remains stationary, and the engines push space away from the ship, thus "propelling" the ship to its destination.

Ok so gravity does not exist. I can see the point but in slshow.info/watch/iphcyNWFD10/video.html why are there gravitational waves if there is no such thing? We need to stop calling this gravity as we say this doesn't exit but say it does by calling it "gravitational". Maybe we need to just stop using the word gravity and start calling it something else entirely.

if you were accelerating while standing still you would be gaining energy, because that is what acceleration is, it is adding net energy to an object.....after accelerating in place as you put it, you would gain mass according to relativity, which is why you can not accelerate to the speed of light because you would aquire infinite mass before you reached C. Your arquement is symantic in nature and not based in fact.
ebagig white
ebagig white Pred 7 urami
7:38 you debunked your own arguement, because gravity obviously exists, that is why you stay on the ground when just standing there, you arent travelling, thus space isnt curving you into the ground. gravity is holding you to it. an object in motions stays in motion unless acted on by a net force, thus gravity is undeniably a force, when you jump you dont keep going because the force of gravity is acting on you.

My wife said that in the example of the two people walking north in the same direction parallel to each other, the reason they bumped into each other is because they were headed to the same single point north. If they were headed east or west, which have no single point like the north or south poles, then they wouldn’t have bumped into each other. Can you debunk or explain where she is incorrect?

Stoney Lonsome
Stoney Lonsome Pred 8 urami
So much of relativity has been proven to be absolutely correct that I've learned to simply swallow the seemingly odd or weird predictions it makes. I'm not saying we shouldn't test it further, we absolutely should but- at this point it's a bit perverse to not believe in the theory completely. It's like evolution- it's stood up to every test so far- even when we tested predictions that seemed crazy to us- like the notion of time being relative. Quantum mechanics is much the same- makes predictions that just seem impossible but- who can deny the results we get from experiments like the double slit? Or the fact that their cell phone works for that matter- proves quantum mechanics is at least partially correct- even if we misinterpret what it ultimately means in the wider context of our perception of realty.

Stoney Lonsome

@Narf Whals Imo this is a problem with how we interpret the theories and what they're saying about reality because obviously the short term, observable predictions they make always pan out- thus our confusion, as you noted. One day we will understand how to reconcile these theories and see them as the same thing viewed from massively different points of view- somehow all those quantum effects have to add up to relativity.
Narf Whals
Narf Whals Pred 8 urami
The problem with the fact that both these theries work so well is... that they work too well. Because they don't agree with each other. With every test we do on them we _want them to be wrong_ . To give us some hint as to where we can do research to get a theory that gets it all right. Dark matter was so promising. General Relativity was wrong! But now it just looks like GR was right all along and there actually just is dark matter... And we've made no progress in that regard for 100 years.

Will a freely falling charge radiate electromagnetic radiation is only but dependant on the point of view. Whether it be observer, a point/moment in spacetime (while observing), or whatever else, you name it. It is just an undeniable truth that when we have a given living conditions/experience, we have to use language/formulas in whatever way to live our reality and to know it. Apart from that, everything is relative to the point of insanity.
Ray Marshall
Ray Marshall Pred 10 urami
Thank you for the great video! However, this brings up two questions for me: All of the explanations require that in order for gravity (acceleration) to occur, it requires that rocket man is moving through the field of the planet. That is, rocket man needs to be moving in order to follow the path of the geodesic. Thusly, it would seem (at least to me) that if he were not moving (through the field), there wouldn’t be a force that would attract him to the planet. Of course, we experience gravity because the earth is spinning and we’re moving along with it so we do follow the path of the geodesic. However, if the earth wasn’t spinning and we were standing on the planet, we wouldn’t be following any path and thus there wouldn’t be a “force” to draw us closer. To use your example of the people walking north from the equator, if they stopped walking, they would stop getting closer to each other. Secondly, I’m curious to know why the speed (or mass) of an object changes how an object follows (or not) the path of the geodesic. If the mass of a large object causes space/time to bend to where a “straight line” is bent towards the planet, why does the speed (or mass) of the object change the “straightness” of the line? For example, if rocket man is passing at a slower speed at an angle towards the planet, he will follow the path of the geodesic and will crash into the planet. However, if he were traveling at a much higher speed, his path towards the planet would be less pronounced. Why would the path of the geodesic be less “straight” just because he’s going faster? One would even think that light would want to follow the straightest path through space and if space is bent (even just a little), light would bend along with it. Thanks again for the great video and any further explanation you could provide would be greatly appreciated. It’s keeping me up at night:)

The happiest moments in my life is imagining a person getting slapped in the face because not only would the force of the slap be affecting the face, but according to Newton's third Law that every action has an equal and opposite reaction would also mean that the slap's force would affect the hand that slapped the face in the first place... and also because of schadenfreude.
Dirt Flyer
Dirt Flyer Pred 11 urami
A man falling would only be experiencing weightlessness for a very short period of time. The drag of the air around him would reduce his acceleration until he reached terminal velocity, at which point he would not be accelerating at all. At that point, if he were able to block the wind, he could make a stack of blocks and it would react just as it would if he were standing on the ground.
Dirt Flyer
Dirt Flyer Pred 10 urami
If you have ever been skydiving, this is the reason why there are only a few seconds that you get the stomach-in-your-throat feeling of falling. Then the air starts to reduce your acceleration and you gradually feel more and more of the familiar pull of gravity, until you reach a terminal velocity of about 120 mph and gravity has returned to it's full effect.

Sorry for my english if something is not perfectly correct. So i was thinking about that video. And we do know that gravity "bends" time also speed does that. So time is like unit of acceleration in spacetime. And i was thinking if in big bang we had all the mass i wuld say in one place. Can this mass along with speed couse so much disturbence in time, that all of this mass spreding around point of big bang accualy was going verry slow as movement in" x,y axis" but time was going insenly fast. So when we see it now it looks like all of this took just fraction of ms, but in reality, for "someone" inside of that big bang it took a looot longer for his point of view. When mass was spreading, so is time being slower and slower, and slower.

Cute video, gravity is a wave of energy that passes through an object where as light does not pass through an object and the reason you can see it. Gravity has an influence on objects but not in the way you are thinking. Airplanes don't fly the shortest distance from point to point as in your example they the follow the land mass so that if they have a problem they may be able to land saving lives instead of ending up in the middle of the ocean and never being found again killing all on board. For the most part you are correct, did deeper. As for time it does not exist it is always now.

But if we are all accelerating due to the curvature of spacetime realative to the Earth's mass, then even a free falling object on Earth is NOT an inertial observer as it is accelerating weather an Earth is pushing up on it or not .
