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.

  • The old-school definition of the word "force" is a push or a pull. Gravity pulls you. Ergo, gravity is a force. Also, the argument that Special Relativity and General Relativity are different because one talks about how Speed bends space-time and the other one talks about how Gravity or Mass bends space-time is simply two different ways of looking at the same thing, i.e., the curvature of space-time. And the curvature of space-time extends indefinitely into space-time, and does what a gravity field does. For clarity's sake, it can be called a gravity field. Semantics is not science. Also, the speed of light is changed by a gravity field. What is the speed of light inside of a black hole? Just saying.

  • Gravity as understood by Einstein is simply moving in a straight line path through four dimensional space time. No acceleration required. Because space-time is warped, and thus time is warped with space, when moving in a straight line through its curvature while no forces act on you, a point in time in the future is correlated with a lower position in space, so your next moment in time is downward.

  • Gravity is not a force. Gravity is the effect of mass on spacetime. It is not a "fundamental force"... it does not reconcile with the Unified Field Theory, and therefore should be excluded from the equation... NOW, you can unify the Electromagnetic force, the Strong Nuclear Force, and the Weak Nuclear Force... there are specific bosons for this. It would appear those bosons are the "unifying factor", the lowest common denominator. AND YET... there is the HIGGS Boson... if the mass of the Higgs Boson were greater, the stronger the gravity would be in the universe... and yet it still does not reconcile??? Maybe another reason? Gravity is NOT an attraction force, nothing is really pulling on you, you are falling in a warped space towards the center of that warped space, the center of the Earth in this case.... objects FALL... but are not attracted... two steel balls, 1 inch in diameter, 1 to 2 inches apart in space will come together in about 20 minutes... NOT because of particle attraction, or electro-magnetism... but because the overlap areas of curved spacetime... and FALL into each other... we and objects are not attracted to the earth... all objects are surrounded by the negatively charged electrons of their atoms... THUS, like poles do not attract... but objects do become close... that is because they FALL in spacetime. There does not have to be a Higgs Boson for this to happen, in my opinion... but then I am not a Physicist, or Quantum Physicist.... and it took me YEARS to get my head around this. I independently came to notice this, in the early 2000's, as I had watched some shows on this...and the shows kept saying..."the gravitational force", or "the force of gravity"... but another show said what Einstein said..."Gravity is the EFFECT of mass on spacetime"... mass curves spacetime... and THUS, gravity is not a force... the "weight" of a mass... causes spacetime to curve, it is not the electro-magnetic charge of the particles attracting objects, those evidently cancel out... the effort of the mass of a ball, indents the cloth... this effect is what we call gravity. HOWEVER... there is "Gravitation-AL..." and that is not the same as Gravity. "Gravitational" is a polarizing motion, or energy... there is an area in the universe that is an area of striated space, polarized... because of this "gravitational force"... that moved through that area. Gravity itself may not be movement, or motion, but affects it, setting up Potential Energy...but "gravitational force"... IS... the energy of that movement... there are GRAVITATIONAL WAVES... in space... waves are motion... a kinetic energy wave... a wave in, on, or through spacetime. Spacetime is a medium. I did not believe that gravitational waves, or even the Higgs Boson, existed before their discovery. I thought..."Gravity does not act that way, gravity does not move OUTWARD in a wave, gravity SUCKS...right?" But GRAVITATION-AL... is not the same as Gravity... It moves... but I don't think that makes it a "fundamental force" with gravitons, and such, but I could be wrong... I don't think there are "space-tons, or time-tons", or particles...Why... because we are told "two objects cannot occupy the same space at the same time"... and yet space expands, and time moves forwards.... movement is action. Action is Energy... but energy does not have to be particles which emit a "force". Electro-magnetic Force, is the movement, and alignment of electrons... do your iron filing experiment...... Now drop those iron filings on the floor... did they align? I hope that helped somewhat...

  • "Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here." Direct statement from NASA. I don't know what you are really trying to prove here, it's like a Hippie saying time doesn't exist.

  • Planets have different GRAVITATIONAL FORCES based on their mass and density. The solar system orbits the way it does based on the gravitational forces or the sun and planets. If objects become too distant from the forces keeping them in orbit they leave our solar system because the FORCE is not great enough to keep them inside the orbit any longer. Please explain this "phenomenon" in terms of GRAVITY IS NOT A FORCE. Einstein himself said that claiming gravitational fields did not exist was on of the biggest blunders he ever made.

  • gravity is north polarity ether field based on the south polarity dominant vibration of earths harmonic mass amplification. It creates an ether pressure differential within all matters south polarity matter dominance, resulting in a magnetic attraction effect. Therefore antigravity can be achieved with monopole electro magnetics. Every twist or turn in the ether causes a magnetic phenomena. Everything is magnetism and matter.

  • think of gravity instead of as the density of space and the curved space analogy gets easier to understand since it removes that visual problem of the curved sheet example. rather than space being curved like a sheet, you experience more space around objects of larger mass because they themselves are more space. as you travel in a straight line "experiencing" space you experience more space in the direction closest to the object of mass basically like a wave traveling through a varying density of air.

    • Continuation of my previous post: I think very large masses effect the trajectory of very small masses as well as the factor of relatively. On earth, if someone came and sucked out the iron core of our planet many things would happen. Putting all other catastrophic, apocalyptic events, went you went to bed and weighed your self on a spring scale you weight 200#s. After your morning coffee and a good health dump you were down to 45#s. That’s a Newtonian change. On the moon you weigh 35#s. That is Newton not Einstein. If it took you 3 months to get to the moon and back you supposedly were now 3 months younger. That is Einstein. Your DNA has decomposed and your bone structure looks more like your grandmother’s according to the Russians. I hope that makes it more confusing. It took me 2 years to get through one year of under graduate physics. I decided to skip the theoretical gibberish and became a “guess and test” engineer.

Second thing, Isnt the reason spacetime bends around large objects because of gravity? Videos always great, love science and learning new things!!

    • Follow up question, if we are accelerating up and thats what makes us "stick" to the earth, how are we all accelerating up, in every direction? Is it because spacetime is curving outward from a deeper spot in the planet thus exerting that acceleration in all directions outward making us accelerate no matter where we are? Id also be interested to see how this pertains to Black Holes, make for a good video id imagine!

  • Yes, but the principal of equivalence fails when tidal effects are measured. So in an accelerated frame of reference G is constant whether you are at the the top of the frame (rocket)or the bottom. But in a gravitational field gravity is less the further you go from the centre of the mass of the object - G is less at the top of a mountain than it is at the earth's surface - so the principal of equivalence falls down (pun intended).

  • I have a simpler question. We don't fly off the earth because the gravity is higher than the centrifugal force of earth's rotation. GMm/r2 > rw2 (angular velocity). Therefore if we move to the north pole, r becomes shorter, while angular radius becomes zero because you are rotating about yourself and there is no centrifugal force. Therefore you should be pulled harder into the earth on north pole. Any idea?
