What is the force that the Earth used to keep us on the ground? Seems like a simple question. Might even have a simple answer. But I find it hard to believe that in this newsgroup about GR that anyone really knows the answer. You might not even understand the question. Okay, maybe the question is too long... What is the force that the Earth used to keep us on the ground? How about What is the force that the Earth used to keep us on the ground? -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.

I understand the spirit of your question, Starmaker. I always ask the same question a different way--a way that you might find on a test: Use GR to calculate the normal force produced on a tabletop by a one kilo brick. I have never received and answer. My version is 64 characters in length.

My version is 64 characters in length. Centripetal acceleration is defined as the property of the motion of an object, traversing a circular path. Any object that is moving in a circle and has an acceleration vector pointed towards the center of that circle is known as Centripetal acceleration.

Mitch to the rescue again! GR only describes the kinematic characteristics of entities located in affine geometries. Or as Misner, Thorne and Wheeler put it "Two bodies, initially falling through spacetime on parallel, neighboring geodesics, get pushed toward each other or apart by tidal gravitational forces (spacetime curvature)". But that is where the characterization ends. There are no GR formulae that describe forces between entities because there are no forces in GR; only the interplay of geodesics about mass, stress, pressure and energy. Weight, you say? There is no "weight" in GR? There is only the colocation of geodesics. Right Dono?

Your bathroom scale measures your weight, not your mass. You can find your mass with a scale and an accelerometer. m = F/g When your bathroom scale shows kilograms, it is because it assumes that you are at the Earth with known g. -- Paul https://paulba.no/

DOWNWARDS! If acceleration is upwards we all would be flying to outer space.

I post now different answers. Relativists don't know, read the Einstein part. "The relativistic point of view would be that the space around the Earth is compressing, but the atoms of the Earth resists this compression. This means that the surface of the Earth is constantly accelerating upwards." "What did Einstein say about acceleration? He envisioned a man in a box. Einstein realized that there was no way this man could tell whether he was sitting in a gravitational field or being accelerated. Because of this, these two situations were equal. By extension, Einstein concluded that gravity and acceleration are the same thing." "Is acceleration upwards or downwards? Image result for why acceleration on earth is upward Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change." "What does upward acceleration mean? The elevator has an upward acceleration (accelerating upward, or decelerating while on the way down) the elevator has a downward acceleration (accelerating down, or decelerating while on the way up)" "Does Earth accelerate downwards? Indeed, every object at Earth's surface experiences an acceleration of 9.8 m/s², in whatever direction you commonly define as down: towards the Earth's center." "Why do we accelerate towards the Earth? When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls." "What is the direction of Earth's acceleration? The acceleration due to gravity is always directed towards the center of the earth. In normal mechanics , we say that it is vertically downward."

In normal mechanics , we say that it is vertically downward." Downward again? Everybody keeps using the word..."downward"? the force that the Earth used to keep us on the ground is coming from inside the earth and reaching out and pulling my feet. not falling down...pulling. What is this force pulling at me? Where in the ground inside earth is it located? A magnet or something? -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.

Apply whatever interpretations to the symbols you like. But know that I have used only well-formed strings and only those rules of inference which are permitted in imaginary arithmetic to generate the valid theorem strings "1 = -1" and "-1 = 1"

But know that I have used only well-formed strings and only those rules of inference which are permitted in imaginary arithmetic to generate the valid theorem strings "1 = -1" and "-1 = 1" You posted this imbecility many times before , Pattycakes. Like before, I suggest that you take it easier with the booze.

But know that I have used only well-formed strings and only those rules of inference which are permitted in imaginary arithmetic to generate the valid theorem strings "1 = -1" and "-1 = 1" Young Veritasium has the finest stable of relativists ever assembled at his disposal to advise on each of his videos. He is bigger that Bill Nye the Science Guy. He is even bigger than Dirk in terms of the number of minds he shapes by means of his videos. Just look at his views and how many videos he has produced. So Vertasium is not blowing his own smoke when he attempts to demonstrate that we all accelerated upwards just to stand still. That's Wheeler, Thorne, Misner & Co. talking. So let's spend some time studying the Vertasium acceleration expression. First, we shall do a demential analysis of the expression. We know that the speed of light though spacetime is c, so its square is m^2/s^2. In order for Veritasium's equation to make sense the units on the Chritoffel symbol's determinate ( or component? ) must be 1/meters.

We know that the speed of light though spacetime is c, so its square is m^2/s^2. In order for Veritasium's equation to make sense the units on the Chritoffel symbol's determinate ( or component? ) must be 1/meters. Correction: Veritasium states that the second term is the velocity through *time* squared. Not spacetime squared. Now we are left with the question of what could possibly be one's velocity (length/time) through time? ∆t/t?? More dimensional analysis: If dimensions for velocity through space is space/time, then by analogy velocity through time must be time/time. So the units on young Veritasium's second term are s^2/s^2. This means that the Christoffel units (det or component?) must now be m/s^2. Meters per second squared are the dimensions for acceleration and not the dimensions for curvature, which is length^-1. It appears as if young Veritasium has given us (and a Relativity-hungry world) a non-starter from the get go. Furthermore, the concept of one's velocity through time mixes categories so as to be logically useless.
