- Added October 2017: The title of this video has always been a bit misleading--whoever at the BBC originally named this clip was clearly looking for clicks (although my inadvertent dropping of the question mark for 4 years probably didn't help)--as the guest here, Marcus Chown, is quite specific when he says, "there is no such thing as the force of gravity", not "gravity doesn't exist", as gravity clearly does exist.
The misunderstanding stems from the fact that in general relativity, gravity is not treated as a force, as it is in classical Newtonian mechanics, but as something that changes the geometry of space-time on large scales, and this is the ultimate purpose of Marcus's demonstration. That said, despite not actually being a force, gravity does rather behave like one... so there's that.
Also, if you're here because you think the Earth is flat, and this video somehow bolsters that supposition...well, you're wrong on both counts.

• Gravity Doesn't Exist?...
Have a nice day!
*this dude just explained gravity*
Musty Burrito I was about to say that!! 😂
Frfr plus how would that explain gravity on Earth
Exactly
Chris Dean and what would ‘our’ understanding of gravity be? because that’s what mine is
How about you explain it instead trying to use fancy words
i thought he was going to drop the bowling ball and made maggots fly everywhere and say "look maggots are flying"
MrZealuk omggg same here loool
me too, something about highlighting the zero g-forces that exist at the apex of the ascent.. funny enough, that probably would have had more scientific merit..
hahah I thought that also XD
Hahahah!!! Same!!!
#hilariuos
That uhh, that experiment only works because of earth's...gravity...
Grimm Teller right on the nail. He fooled himself infront everyone.
Oh God. It supposed to be from another point of view. Gravity works in other dimensions we're just seeing/feeling the effects of it while not being able to look from the 4th or 5th dimension and fully understand it. Place a 3d object inside of a 2d world and they won't know what's going on because the can't fully see it. All they see is a line and can't feel/understand the change in depth that makes them roll towards it. Really not difficult.
thecrazyslopoke OP is right. It only works because of gravity. Just because the effects of gravity change because it can appear to us as a resultant force rather than an intuitive force doesn't mean it doesn't exist like the video title suggests. You're both right and the implication of the clickbait title is wrong
holy fuck.. it is insane how people like you even know how to turn on your computers rofl.. the existence of our colloquial idea of 'gravity', which you used in that idea here, is used in the experimental design, and has nothing to do with the theory of why gravity doesn't actually exist when talking about spacetime..
The point that Marcus was trying to make in this demonstration--although not entirely succeeding, judging by many of the comments here--was *not* that gravity doesn't exist, but that it is not a force in the way we typically understand forces, even though it generally behaves like one. This was an attempt to demonstrate the move from the Newtonian model of gravitational force to the Einsteinian model of relativity and curved space-time.
By the way, I too am not a physicist, although I have a piece of paper from an illustrious university which says I could call myself one if I wanted to.
I'm a little bit sad that most of the comments are so idiotic and the title is misleading. The guy clearly said there is no FORCE of gravity which is obviously true in regard to General Relativity, and then he just explained, more or less, what gravity is in reality - that is: a curvature of spacetime. Gravity was a force in Newton's theory but nowadays it's okay to say that the force of gravity doesn't exist. He (the guy in the video) did NOT say that gravity itself isn't real.
As the re-uploader of this video, I wholeheartedly concur with your assessment.
@@IthratCordwallisso sad. Scientism and its relation with bad science communication is disheartening
Sorry, first I got them as magnet
shashwat singh
Same
Me too
The maggots escaping the plane went down a wormhole.
Exactly, they hit the floor... an other dimension.
Tom Minter ahahahahha true
Best pun ever! (Based from the video)
You act as if images are the only evidence that could prove something exists.
Barzzz🔥🔥🔥🔥
Funny because he is still using gravity to explain no gravity.
m4ticc what he explained is how gravity works. But he's saying that it's not gravity.
m4ticc how do u explain how the bowling ball went down
Gravity doesn’t exist as a force. It’s all about density.
He never said there was no gravity. He said there was so such thing as the FORCE of gravity. Obviously there is something attracting masses, but according to Einstein this isn't a force but just mass bending space time (Which is what the guy in the video explained quite well)
He never said there isn't gravity, he said that gravity is not a force. This is accepted by every credible physicist in the world.
It's either im as dumb as shit or this guy just explained how gravity works while trying to convince us that there is no such thing as gravity
Rhys Clunis he explained that gravity may not be what is commonly understood as this mysterious force that pushes us to the centre and emphasises the perception of gravity as more of a slope created by the bend of space time. Two different understandings of what gravity is.
Rick Lokers thats what im saying
Alessandro Damario I think I can understand that, but then when you look at most super massive objects they tend to be spherical in shape. That suggests to me that there is some type of force pulling them in all directions towards the center of the mass. This would lead me to believe that gravity is a force that is acting upon mass and spacetime simultaneously.
Rhys Clunis He said the "force" of gravity doesn't exist and not that gravity in general doesnt exist. I too missed that at first.
Juicy Dangla What is force? Force is either you're pushing or pulling, now there is this big bowling ball pulling all the maggots towards it. What do you call that?
And in this model, what does the gravity pulling down the bowling ball represent?
Its only attracted downward because the sun's mass is pulling the ball to the earth
Austin Texas I am saying, why does it fall down that ditch? The only reason why things fall down a ditch IRL is because of gravity. So describing gravity with gravity is like saying: dog: a creature exactly the same as a dog
Kaleb Bruwer It's called density. Don't get it confused with gravity. Newton did...
This is trying to model orbits rather than a "pulling down force", ignore the maggots getting pulled towards the ball because of their weight and concentrate on the maggots trying to move in a straight line the trampoline but end up moving in a curved path.
In classical mechanics: The Earth moves around the sun in an ellipse because there is a force pulling the Earth to the Sun and an equal and opposite force pulling the Sun to the Earth (but because the Sun is so huge, it does not accelerate as much as the Earth).
In Einstein's theory: The Earth tries to go in a straight line in space but because the Sun's mass distorts space, the straight line path is curved.
Primus Productions ok so it explains orbit, not gravity. Thanks
a flat earth believer just sent me this video to watch because he thought he disproved gravity lol
chilipalmer10 Haha dat idiots. :D
Fabian Frei so if their idiots and its retarded to think gravity is fake.. Why are yah here watching this?
steven blackburn Because I needed a good laugh.
Fabian Frei I posted a new video that hands down disproves a glove you should check it out and give me you scientific analysis
steven blackburn I could do but I'm bored about the flat earth vids. If you know 2 or 3 videos, you know them all. Always the same "arguments", nothing new and never the slightest evidence for a flat earth. I could proof your video wrong but i know that it's wasted time to discuss with a flat earther and my English isn't good enough for this.
What he is explaining is still gravity, he’s just explaining to us what we think “gravity” is, is not entirely true and that we should be more accepting of his time and discoveries.
Og Bqze no he was just explaining Theaterarbeiten isn’t a force
Og Bqze no such thing as gravity. We're on a plane not a travelling rotating mass in the shape of a sphere or spheroid or oblate spheroid. Earth is FLAT and MOTIONLESS.
rio skyscraper
Lol you're Dump
Monkey D. Ichigo you may want to rethink that and edit in order to save face.
rio skyscraper
English isn't my mother tongue so I don't understand all you wrote, but you belive in a Flat Earth so: No
I think what he's saying is that gravity isn't a force in the context we are taught in school, but that the effect is caused by the curvature of the warping of the space-time fabric, as demonstrated by large mass objects in space. Einsteins theory of general relativity.
that doesn't make the current idea wrong it's just not gone into in mind boggling detail to school kids that are more concerned about the colour is of the pencil they are chewing on.
This is EXACTLY what he's saying. But everybody on the internet has a PhD in Physics so you can't tell them anything.
It doesn't exist in a vacuum
It doesn't exist without air
@@cdnshadow1 Then why do things fall downwards in a vacuum chamber?
The guy at the end is correct
Jesus there are a lot of people who really missed the point here, and take things waaaay to literally. Do you honestly think a bowling ball and trampoline can adequately show the warping of Space and time? It's just a demonstration guys, and fuck me if you still think the Earth is flat then I don't think there's much point in you watching these sorts of videos, I think Eastenders or Hollyoaks is more you cups of tea.
Suvzillaa to be honest bowling ball and trampoling are fairly accurate as to what physicists believe pretty solidly to be what the warping of spacetime is like but the ignorance of people always astounds me. How are flat earthers a thing when you have the wealth of human knowledge at your fingertips
This comment is perfect.

how were the maggots drown to the earth Got u their sonny Jim
The concept of gravity being strong enough to pull something heavy down with a strong force, but unable to pull something light down even stronger is counter intuitive. I think this is why some get confused about what it actually is.
everything manipulates spacetime. those are lighter materials, but they do not escape earths gravity.
the clouds do not escape earths gravity and gravity brings them back down as raindroplets.
Proves there's no gravity...using gravity
Rithujith Roshan He didn't disprove gravity. He showed Ein's model, according to which gravity isn't a force but tun spent space time
ok..let me rephrase. Proves there's no FORCE of gravity using FORCE of gravity.
Arkadi Danielyan Gravity is 4d accoeding to einstein and i know that..this guy doesnt speak anything about space or time...atleast not in this video, maybe he explains it well in his papers..anyways, im just saying he could have used a different analogy not some maggots on a trampoline.
lol Exactly
worms don't think they exist on a 2D plane, they move in 3 dimensions
I swear I made the exact same theory 4 years ago when I was in the 8th grade and my teacher laughed at me and told me to be quiet and my classmates laughed at me and called me dumb. I still believe in this theory I’m happy to see I’m not alone.
This theory is true. Einstein himself said that gravity is a curvature in space time. Just like it was demonstrated here. So, the teacher was dumb to call you dumb.
Goes farther than that.. no such thing as gravity!
Gravity exists, but it's not a force. This is what Einstein's theory of relativity tells us.
From our perspective gravity works like a force, and we are taught it's a force, but it's really a simplification.
The Newtonian principles can be used to calculate gravity, but not to explain the mechanism behind it. A massive object will warp space-time in such a way that an object following a straight line through space-time will be drawn in. In our 3d world the objects path is clearly changed. But its path through space-time remains straight until acted upon by an external force (which gravity is not)
Jonatan Larsson there is something i dont get, the way you are putting in "gravity", how would it affect a body that is not moving, for example a "maggot not going on a straight line"? I understand the movement when i watch the model example on the vídeo, but i just cant understand it in real life.
Maybe im being a little confusing, what im trying to say is: from a newtonian perspective, i understand why the maggots are falling, but why would earth fall towards Sun If, at any given moment, their movement compared to each other doesnt exist? And how would the fall moviment be? I just dont understand what creates the movement
Wrong, gravity doesn’t exist, just density and Buoncey earth doesn’t move
Half of the comment section didn't get what he just demonstrated there.
Pretty much everything is a theory, this guy saying gravity doesn't exist is his theory. It's not supposed to be a force, it's supposed to be the distortion of space that anything with mass creates.
Put a rock in a shallow plate of water and drop a maggot in, the maggot will float to the rock and stick to it.
Spaceman Spliff This one was your theory
Theres a scientific theory,which is proven and backed up,and theres the dumb theory that everyone thinks its jsut something someone thinked about,gravity is a scientific theory
Graham Rathbone It's the same principle.
Grafity is a buckram force. Its like Coriolis efect but in 4D :)
You moron. So you say it’s not supposed to be a force but you say it affects space and time?
Wow!
But the universe isn't a big mac
Or is it ????
DAN DAN DAAAAAAAAN
DJRICKYDEEUK 👏🏽👏🏽
Iv always believed it was a cheese and bacon tendercrisp
Word trick. He said no such thing as "THE FORCE" of gravity. He didn't say there's no such thing as gravity.
Gravity is the force that holds you down? Ergo if it’s no force gravity doesn’t exist
Him proving that gravity is just a theory by using a theory will be dismissed thank you very much
It's funny when people use gravity to disprove gravity.😂
Correction: Marcus states there is no such thing as the "force" of gravity. At no point does he say gravity does not exist; in relativistic physics, gravity is not considered a force, but an attribute of a system's geometry.
Gary
You need to use the theory of comprehension to prove you literally paid attention to the guy saying gravity isn't a force😂
Gravity, like death is a human construct.
I hadn't visited this video for the longest time; the main reason I had posted it originally was because it had come up in conversation with some friends of mine, and they hadn't been able to watch it because of regionalisation issues, so I had re-uploaded it.
Reading through some of the comments here, though...I am rather concerned that the concept of a flat earth has been forwarded as a plausible hypothesis. Just...no. The earth is an oblate spheroid; the evidence for this is overwhelming, and is only disregarded by those who think they are much cleverer than they actually are.
Also, whatever gravity *actually* is (the jury is still out), it acts like an incredibly *weak* force. That's why one can blow a feather into the air with nary a breath.
+Andrew Neil Carpenter Ya reading these comments and encountering some of these people on facebook in debates makes me think god there are some stupid people on this planet. Hell just got down talking to one who even thought we never went to the moon. FUCK for heavens sake the ancient Greeks proved with mathematical calculations that the earth was round.
+Andrew Neil Carpenter Where can I find the full version of this series?
+Andrew Neil Carpenter much more clever*, but could you clarify for me what an oblate spheroid might look like?
+Jill Montegomery read this and it will explain: en.wikipedia.org/wiki/Figure_of_the_Earth.
+Jill Montegomery And what makes you think that picture, and ones like it, are perfect spheres? The flattening at the poles is very little, about 1 in 300. Do you think your visual acuity is good enough to see that in small photographs? I'm thinking not.
However the maggots would not fall towards the bowling ball without the force of gravity. So what pulls us 'down' on the curvature towards the sun?
Ed Smith the sun bends space time just like this guy explained Its Einsteins theory
So does the earth
theory, is not truth, its what they believe, if it was fact it would be stated as such FACT
No no the curvature is what keeps us going around the sun. We have a certain amount of momentum which keeps us going along that curvature thus creating an orbit
Aime Bouchard okay you dont know what theory means in science. Heres a quick runthrough. Theory in your life is like a science hypothesis, its what you know and what you think should happen. But a theory in science is a principle that is well supported by proven scientific laws and experimentation, a theory in science has massive amounts of evidence as opposed to an average joe saying they have a theory which means a guess. Scientific theories explain many many things if they are correct. For example the plane of spacetime (plane meaning flat) explains gravitational waves, theoretical wormholes, i believe it helps explain time dialation and many other proven things
Gravity and the theory of relativity explained with a trampoline, bowling ball, and maggots, the maggots represent flat earthers.
Immediate problem with this experiment is that its on a two dimensional plane not a 3 dimensional one and the bowling creates a crater which makes a slope on the trampoline which is still falling with gravity downwards. This experiment literally proves nothing
Dude, that is gravity. The Valley is created in 3D, cause if it wasn't 3D there wouldn't be a "valley". He's right, he's just saying that there's no such thing as force of gravity.
Klejdi Vrekaj you missed my point his theory just backs up gravity
Metaphor The Great ah ok
BTD Null It isn't an experiment, it's a visualisation. Of course it proves nothing, it's not supposed to. It's just supposed to make it easier for you to understand Einstein
"There's no such thing as gravity" *explains gravity*
stupid misleading title...should be ."GRAVITY IS NOT A FORCE"
Hoorah; someone who finally gets it!
+Andrew Neil Carpenter F = M1*M2*G*Rhat / R^2
[Newtonian Gravity, a close approximation. Technically Einstein field Equations truly represent what Gravity is]
Gravity is the Force that Mass 1 Exerts on Mass 2. It is a force. That is why it is called "The force due to Gravity".
All this video does is "shows" [rather poorly I might add but he tried] how that force is actually created, or why it exist. But it is still a force none the less.
I do not believe the Einstein Field equations treat gravity as a force, either, even though the Newtonian equations (which *do* treat it as a force) are a good approximation to them.
The most genius and simple experiment to demonstrate what gravity actually is.
Lol, it would still require Gravity to hold the Earth ( or the Maggots ) down to be able to Roll otherwise it would just continue in a straight line until it made contact with something else :)
Craig Peterson that's what I'm trying to say, how does this guy describe what's going on, what does he call it? If not gravity, what's pulling these maggots toward the ball, it had a larger mass than these maggots
Gravity isn't pulling the maggots towards the ball. The whole point is that the ball distorts the sheet so if the maggots travel in what they perceive to be a straight line, then they will inevitably go towards the ball. Masses affect the geometry of space-time.
Craig Peterson actually the solar system dont pretty use gravity its the magnetic force
Haha your public school at work here. You dont get it.
tf1977sled lol agreed
They are fast-those maggots -some of them managed to exceed the relative escape velocity.
+Ralph Latham The biggest maggot stuffed it with the bowling ball.
they wer so fast that they escaped spacetime itself
Can anyone tell me why the moon is in the earths gravity and not the sun's more powerful gravitational pull?
The moon *is* in the sun's gravitational pull. The interactions are surprisingly complicated (and that's before we even talk about "the three body problem,"), but here is an interesting précis:
www.wired.com/2012/12/does-the-moon-orbit-the-sun-or-the-earth/
The Sun is an explosion held in its state by the force of the explosion and the gravity of the core, one day the explosion will overpower the gravity and the sun will expand. The Moon is actually slowly moving away from Earth (6 inches or so a year or something). The whole Solar System and Galaxy and Universe is being pulled apart. Nothing ever stays in any position. It's all constantly changing. We just aren't alive long enough and time moves too slow to notice.
Because space time fabric pull is dependent upon the mass for creating force around it...
So in this case the sun is exerting more force bcz of its mass and earth creating less pull in space time fabric...
Now moon being so less mass compared to earth ....And being so far to sun and being so near to earth ....It will fall in nearby pull ..
Hence the case...Hope u understand the logic behind the video....
The main logic is ,it's not the gravity that's pulling u,it's the space time that's pushing u down the pull created by the heavy masses.
so in other words you don't know ? It just sounds like you are regurgitating information someone else has coughed up which makes no sense , could you explain this in a way we could all understand ?
It's been explained to you 4 different ways now buddy. I f you still don't understand then that's your fault, it certainly is not Ajay's fault!
Small brain: "The force of gravity is real!!".
Big brain: "The force of gravity is fake".
Galaxy brain: "The maggots have escaped this plane of existence".
Maggots are sliding downwards due to gravity only.
This is such a stupid analogy. It gets trotted out again and again, but it makes no sense. The indentation in the trampoline only means anything because of gravity. It's using gravity to explain gravity. I don't know that the theory itself is as daft as it seems in this analogy for it, but this "bowling ball warping the fabric of spacetime" thing really isn't helpful.
Bababoom Baboom Mass bends space time Look up general theory of relativity
I guess. Analogies like this always use the idea that it's like something else that's easier to grasp intuitively. The analogy here is that gravity is like gravity. If a lens was used, that actually does 'shrink space' and you saw how lines on a grid were 'pulled in' by the space-warping effects of the gravitational body, that would be an analogy to a more intuitive kind of warping. A gravity well that you fall into because of gravity ... that doesn't really convey much of anything.
That's not even the worse problem of this analogy.
In fact, in addition to depending on the very existence of gravity in order to "explain" gravity, it also not only depends on the existence of an additional dimension, but also fails miserably to convey the "Geodesic" principle. In Mark Barton''s words: "gravity as it applies to everyday objects doesn’t work by curvature of space, it works almost entirely by curvature of the *time* aspect of spacetime, a.k.a. gravitational time dilation (...). Only light signals are affected by curved space to any significant extent. (...). Inertially moving objects travel along paths of maximum elapsed clock time. Without gravity that’s a straight line at constant speed, as with the earth twin, and with gravity it’s a path that “likes” to linger at high altitudes (where there’s negative gravitational time dilation)."
+Marc That's interesting, and coherently explained, thanks.
Curvature of spacetime, is it? How would you even come up with that? Must have liked the sound of it. How do you confirm that? How can you even say that space and time are related like that, to be together influenced by mass? TIME influenced by mass...? Ridiculous idea. Now everybody believes this because they saw a documentary on Discovery channel, saw a bit about it at school and have seen interstellar 3 times. The only mass that ive seen influencing time is people's bodymass and its influencing their lifetime.
*Sigh* another scientist playing with semantics to dramatise and wow the audience. No matter what you choose to call "gravity", or however you wish to conceptualise it; whether you think it's a property of mass to induce curvature in spacetime, an intrinsic Newtonian force bewteen all that contains mass, an exchange of fundamental particles, or a phenomenon which arose from certain quantum mechanical fields, *gravity does exist in all sense of perceivable and testable reality* . Just as I may redefine 1-1 to be equals to 3, doesn't mean if I eat an apple, I'll get more apples. Redefining how we *model* reality does not change the physical reality itself in any way shape or form, just as it applies to the existence of gravity.
He Ang pro_CTB Thank you!
That's an excellent explanation.
He Ang pro_CTB , well u are just crapping out for no reason.
he had no intentions of falsing the gravity theory.
He just wanted u to see the world from different prospective or to get the bigger picture.
cuz if u just mugg up formulas and kept going with that nothing new will ever come out.
New formulas and theories lies behind a person who thinks differently than his mugging classmates and gets the bigger and his own picture of world.
Thats why we should teach the students about basics and pillars of Einsteins theory in middle schools . not the lengthy formulas but how we can reach to a different prospective.
He Ang pro_CTB Well, only one of your theories can be true. Knowledge and truth of any scientific principal is how we advance. If your theory of how something works is wrong in any way, it lessens that knowledge and stunts advancement. There aren't gravity particles. It isn't a force.
TIM Jones Actually they would never call it a fact either. Science has hypotheses followed by theories followed by laws. Laws can also be disproved, making them less than facts.
I thought he was gonna pour magnets onto the trampoline. When he poured a bunch of maggots I jumped in my chair.
Assume the whole space as this trampoline with no color and think of our sun as that bowling ball in the middle. This will create a depth in the middle of our space. So my question is that by which force will the earth or other planets will revolve around the sun ? If you say it will revolve just like Maggots did here in this example then I will have to ask you where is that force coming from which is driving those maggots nuts . In this example whatever happened, it happened bcoz of gravity but how will you make us understand the same phenomenon in outer space ? Please reply , I need answers
I think i understand what you mean i think your saying if the magots roll toward the bowling ball then why do our planets not get pulled toward the sun or bowling ball.
I hope that makes sence
RedShift Raps no I think the planets follow an elliptical orbit around the sun but not like the 2D revolution but in all possible dimensions. Mu question is if the maggots are rolling towards the ball even in outer space then please explain me that what type of force is that which is creating a crater like in the middle of the trampoline. How would you explain mass without any force. Even the smallest particle of an atom is in its place due to force. If you can explain me where is that electron getting that amount of energy to hold itself with the nucleus then I might be able to understand a little of what you said above.
As usual, conflating the scientific definition of theory with the colloquial usage.
Lol when there's no evidence or flat Earth. Flat earthers will result in just anything for evidence - Albert Einstein 2017
Wisdomian Law some guy sent me this thinking he disproved gravity. I laughed for like 10 minutes straight
you cant prove gravity neither
Aime Bouchard Oh i can, i just Dont think you would understand
*you cant prove gravity* uhm... we observe forces... gravity is observed as the force that causes massive (objects that have mass) to attract each other. Saying you cant prove gravity is like saying I cant prove my hand is real. Like you can see it. Gravity is a governing force in the universe. This isnt a disputable thing. Shit is drawn together. You cant say "buoyancy" thats caused by gravity pulling a fluid down so the fluid tries to occupy an objects position by creating an upward force on it, if the object is to dense it wont float, if the object is not too dense it will be pushed upwards by this force. This only happens cause gravity tries to pull the fluid into the space the object is occupying. You can also see it very clearly in orbits where gravity keeps the momentum of stars and planets in check keeping them in an orbit by curving their trajectory so that it curves around the body it orbits. The ignorance of people on things they can SEE is astounding. Are you going to tell me that im not real or that I cant prove that I exist within our reality?
mickey cos troll lol wtf are u talking about hahaha
Oh the irony , that's like standing under a tent saying rain is just a theory, you'll only get wet if your remove zed tent
how to tell he does not understand what he is talking about????
2:10 "the Earth is moving in a straight line... in a.... in a... between 2 points... in a... in a... curve thing like this..."
Antonio Henrique Padua
how could a straight line be a curve?
imagine yourself and a circle in 3d space. get exactly in the center and look around. what do you see? and that will be all you see.
Antonio Henrique Padua
is it like a straight line curved by the sun?
Antonio Henrique Padua I think what he means is that something is bending space itself which means that if you go straight in space and that space is bent, then it's like you're going to a curved line and I think that something is gravity. You are really going through a straight line ofcourse, but since the space you're going through is bent, a 3rd person whose space isn't bent will see you moving on a curved line.
But if I understand Einstein correctly he posited gravity was a “pushing “ force not a “pulling “ force” ....?
If u say gravity is a pushing force, then why the black hole is invisible...???..
Mahesh Kumar I don’t say it is, Einstein said it is.
🤔
www.quora.com/According-to-Einsteins-theory-of-relativity-gravity-is-not-pulling-us-down-but-space-is-pushing-us-down-Does-that-mean-there-is-no-gravity
The way i imagine it, the amount of mass an object has corresponds directly with how much it pushes space-time around itself, therefore attracting objects to itself and creating the perception of pulling.
SMM
That's Tesla's Dynamic Theory of Gravity. . . .
Eli S. Ramirez That’s just like saying air is non observed force so it doesn’t exist so get back to reality... 🤦🏾♂️💆🏾♂️🤦🏾♂️💆🏾♂️🤦🏾♂️
the black guy at the end haha
Calm down people, he isn't saying Gravity itself doesn't exist. He is saying that the *FORCE* of gravity doesn't exist.
In relativistic physics, gravity isn't considered a force, but more of a attribute of a systems geometry. General relativity says that energy (in the form of mass, light, and whatever other forms it comes in) tells spacetime how to bend, and the bending of spacetime tells that energy how to move. Going with this, that means Gravity is objects falling along the bending of spacetime.
Thats what this guy was trying to say. The concept is hard to understand, and the model that he is using isn't that gret. A computer generated model would've been easier to explain.
Well that was a waste of maggots
could have used marbles
GRAVITY FALLS!!
Gamer Boy fuck I miss that show
Gamer Boy
is gravity falling for americans or chinese? and which way us up? gravity pulls toward center of the largest mass, thats why were spinning into the sun and a super massive black hole
C moon
its just an example he used to demonstrate the thoery of space time, what he was trying to show is that a mass (bowling ball) bends this space-time field we are surrounded in and that anything with mass will bend this space-time continuum. this theory is very confusing and complicated just to show through one example, i dont like how people jump to conclusions and disprove the guy is saying that "but the example is only possible because of earths gravity" its just a fucking example that is given from an outside percpective. if it was that easy to explain if wouldnt have taken the the worlds smartest known human to figure this theory out. this doesnt even scratch the genius space-time theory and general relativity theory. go into this theory enough it explains how space (area) time and mass are all intertwined and basically one thing (kinda).....sorry physics and space is life
ZM Custom sorry to tell you the brightest man to ever live was Tesla, and he didn't believe in gravity either.
Ejwbwb kwnes a flat brain to go with their flat earth ;)

Hating another human for their opposing beliefs? Very enlightened of you.
Gravity is just what we call whatever the fuck is making things come towards a center of mass. Gravity exist, you can see it. You can not deny the simple observation that objects is zero-g are attracted & the strength of the attraction is directly effected by mass.
What he is saying is that gravity is not a force, but rather it is the bending of space-time. But we don't actually know if this is the correct mechanics that govern the very much real Gravity, that is undeniably real, so we call it the 'theory' of gravity. But no physicists would argue that gravity it sell if not real. That's asinine.
There’s a big difference. The earth is FLOATING IN SPACE and the maggots are ON A SURFACE.
Yeah everything he said can be summed up with one word....“gravity” 😂
Bullcrap
Explain
Annnnnnd that’s still gravity
what would you describe a force as? a magical pull or push with no clear cause? the dent or curve in spacetime that pulls things towards it caused by, in this case, the bowling ball, is what we refer to as the force.
"Gravity doesn't exist"
Proceeds to explain the concept of gravity...
No. he said gravity is not a force. big difference
The earth is flat
like u
dez7inyable do your research and you will see you are the one brain washed:) look up ODD on TH-cam you will thank me brother.
dez7inyable it’s a start to open your mind if not you are going to miss out on the truth just watch it!! then you will want to look into it even further and see the truth.
dez7inyable make sure to type in odd reality he saves you from doing a lot of research in his videos please take your time to watch, it’s no joke why do you think so many people believe the earth is flat.
dez7inyable nasa got everyone brainwashed we already exposed them of all their lies:) you keep thinking that
The unanswered question is why does the trampoline go down when the bowling ball is placed on it, not why the maggots move downhill. There is no reason for the bowling ball to cause the trampoline to go down and create the "valley" since gravity exists only after the "valley" is created.
Sad I won't be alive 2,000 years from now. When people have accepted that we were not at the pinnacle of science in the 20th century, and that most of the theories were wrong.
Just to re-post what another person said as a reply to these comments as well...

Gravity isn't pulling the maggots towards the ball. The whole point is that the ball distorts the sheet so if the maggots travel in what they perceive to be a straight line, then they will inevitably go towards the ball. Masses affect the geometry of space-time.
For those (most) of you who are failing to understand what's happening here:
This guy literally just explained in the best way possible how gravity works, and then said that gravity doesn't exist.
Why did he do this? Why doesn't he realize what he's just done?
He's intelligent but not intelligent enough to be aware of what he doesn't know. He's falling into the territory of not realizing that gravity and all of science really is DEscriptive and not PREscriptive. In other words, we are observing the universe and describing it in our own language, we are not coming to a conclusion on how things work and then working backwards from there.
Gravity is just a label we put on a phenomenon we have observed, it is not the phenomenon itself.
So he's telling us that the earth is actually like a roulette ball even though that's caused by gravity? Amazing.
What he said is correct. Space around us is not just empty space. It is real. It is a thing. Newton says earth pulls everything towards it, Einstein says Space pushes everything down into the valley.
And this is why life is simply all about perspective
There you go. He just explained einsteins theory of relativity.
That psychadelics joke at the end was the cherry on top
He's not saying there is no gravity, just that the way most people think it works is actually incorrect.
He didn't show gravity doesn't exist. He's just explained what we mean by gravitation, it's the apparent force created by the distortion of space time by bodies of mass -- that's just as real as anything else and it's this that's referred to as "gravity".
there is no gravity, but this man explain that we have electromagnetic
Um, no... but thanks for playing!
I agree 100%. It’s not a mythical pull toward each other, gravity is basically being on the side of a very steep hill.
Newtonian gravity tells us WHY the mass is attracted to other mass (pulling force between the object)
Theory of Relativity tells us HOW Newtonian gravity works (it explains the real 'identity' of gravity which we feel it as a force)
His direct intro was that "there is no such thing as the FORCE of gravity." Not that gravity isn't real, but that it isn't a FORCE. The following is a direct quote from en.wikipedia.org/wiki/Force
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull.
His argument is that even though we have believed that gravity is a force "as described above in the quote", that it is more of an alteration of the space around us. Gravity doesn't directly cause the effects like a force does, but indirectly. Whether you believe that part or not is another discussion, and I admit that I am unsure on this point.
To fully understand the point he is making, you need to understand what he means when he says "spacetime", and not "space" and "time". This isn't a new idea, it was an idea that Einstein had, though I am unsure if he is the first who had it. Essentially it is the idea that space and time cannot be separated. Space effects the passing of Time. GPS proves this to the entire world through the calculations it has to run to keep an accurate clock time. The faster something moves, the slower the matter in the object moves, and so the slower time passes for that object. Satellites have to correct for this all the time, and each satellite must run different calculations because of their different speeds and distances from the Earth. In this video, he is saying that mass has an effect on spacetime, and so bends the spacetime. This is what causes us to move toward the planet and not a Force that pushes us toward the planet.
Technically gravity is just a theory. Everything in science is pretty much a theory. We explain the fact that everything is pulled toward earth as gravity, but the concept of gravity is still just a theory
I think this guy dropped too many acid tabs one night, then listened to a Kanye album played backwards, causing his brain to melt. Marcus... can you calculate 1+1?
Jesus Christ, *This guy isn't saying gravity doesn't exist, he's just proposing the idea that gravity isn't a natural force! He's saying its an illusion caused by massive objects bending space time and we percieve that bend as gravitational force!*
Its not that hard to understand...
Boy, some of the comments here make me weep for humanity. To be fair though, general relativity is not something you can explain in less than 3 minutes, so any thought experiment on it is bound to be flawed. But, just to make it clear, there is no debate if it's either newtonian physics or general relativity, it's the latter. General relativity can explain phenomena concerning gravity that newtonian physics can't explain.
I was waiting for him to drop the bowling ball on the trampoline to make the maggots fly all over the place lol
We really can’t blame people like this. No one there explained it very well at all, but that’s expected as this is television and is meant to entertain.
Wtf is he talking about. There is a bowling ball on a trampoline, you see. Here it is. Right here. Not there, but here.
British People: I use maggots to visualize concepts
Damn.. He fierced the truth straight through the point. Such an inspiring demonstration.
For those who dont understand it , he´s making and analogie from that trampoline to space time. In reality ,what we call a gravitional pull , is in fact the destorsion of space time by objects in it depending on their respective mass . This is knowed from the proofed Einsten thoery of general relativity .
I'll wait at the bottom of a huge cliff and the people who think gravity doesn't exist, jump down and show us all how things work.
Sir please explain why the worms are moving down towards the Valley and not upwards😑.
..
Let me tell bcoz of gravity.
and suddenly everyone in the comments has become a space genius
Yeah, I saw the title and came here just to say gravity does in fact exist. lmao
He is Not Saying Gravity Does Not Exist...He is Saying Gravity as We Know it is The Wrong Theory...Obviously i Have No Idea if This Demonstration is True But it Certainly Makes a LOT of Sense
Yeah... that's where Albert Einstein comes in 😂
Drop the bowling ball on his head and then ask him if gravity still doesn’t exist.
He is explaining space on two dimensions. The "pull" the mass brings to the object bends time. Sooo bending time in 3d is like going in a circle? For the object? Or the charge of the object pushes us down like a magnet?
Everybody here saying he just used gravity to explain why gravity doesn't exist, yet I'm here wondering HOW DAFUQ YOU GOT PRINCESS DIANA ON THE SHOW ?!?!??!
Gravity creates the force from which the indentation originates, the bowling applies a force on the trampoline causing the indentation on the centre on the trampoline and subsequent "downhill" attraction to the centre, without gravity in this context the bowling ball would sit perfectly still on the trampoline which would be flat and non-indented. He is attempting to use gravity to disprove gravity.
bevan thomson
So hold on mate, you mean to tell me that space time, like the trampoline, could be broken through? What do you fall into if you ripped space time? Where does gravity originate, if an object is being pulled into the fabric of spacetime? Meaning if space time is a fabric like the trampoline, and EVERYTHING we know exists on this fabric, what is the mechanism by which gravity can effect the Earth, the Ort cloud, and Sirius, which would appear to be on different planes, in the same manner. Also, what causes something like a rouge planet to have its own gravity, with seemingly nothing around to provide attraction? Just some thoughts.
lmao the dude tried to say ''There is no such thing as Gravity'' he legit just explained it, the only different thing that he explained it on a Flat surface
So you're saying that there is no force of gravity by comparing a piece of fabric to space-time? There should be a limit to what you can conclude from assumptions.
He says that we don’t have gravity, and then tells us the definition of gravity and how it is what gravity is ...which is what we have
"It's only a theory." Isn't that all we ever have?
my man proves gravity and works in gravity but claims it doesn't exist. DEAD
Man I must of missed the giant bowling ball at the North Pole
It's funny cause if gravity didn't exist that bowling ball wouldn't have sunk into the trampoline
The gravity is the bowling ball attracted to the ground, the whole reason he says his theory works is because the trampoline is a secondary circus
He just explained how mass curves space time.
