>standard model
>unable to explain gravity

dismissed.

>In case of gravity it's that masses curve space time, since objects take straight in space time they will then follow a curve in just space

Curved space time is a fun model but it explains absolutely nothing. Yes, there is a gradient around massive objects but that doesn't explain what is actually causing the "pull."

there is no pull.
just geodesics.

I think ITT stoned people.

Example: Explaining a wind turbine.

>1) Air-space-time (a made up concept) curves around the wind turbine blades and the blades follow the path of this curve.

This explains nothing.

>2) Air is actually made up of particles of nitrogen and oxygen. These particles are given velocity via heating by solar radiation. When these particles impact the blade of a wind turbine, they transfer some of their momentum to the blade (causing the particles to slow down) and this causes the blade to speed up and rotate around the fixed axis of the turbine.

This IS an explanation.

>Curved space time is a fun model but it explains absolutely nothing. Yes, there is a gradient around massive objects but that doesn't explain what is actually causing the "pull."

Actually, yes it does.

An object will, in the absence of force, travel in a straight line through space-time forever. (This is equivalent to saying it's moving at a constant velocity.) Newton's first law.

If space-time is curved, then this does not change; the object will still move straight forwards. However, the equivalent of a "straight line" on a curved surface - a geodesic (en.wikipedia.org/wiki/Geodesic) - is also curved. So an object in curved space-time will follow a curved path through space-time; this is equivalent to the object accelerating over time.

Incidentally, this is what the bowling-ball-on-a-rubber-sheet analogy is *actually* attempting to demonstrate; it's very confusing because people often come away from that analogy rather frustrated because "Okay, but what pulls stuff down the rubber sheet? Gravity? That doesn't answer my question!"

It would actually be a lot less confusing if you did it in orbit, so analogy-gravity wasn't getting mixed up with actual-gravity; the important point is that stuff rolling along that curved sheet is trying to follow geodesics along that surface, just because that's what inertia *is*, and so its path ends up bending.

that explains how moving objects are displaced, but not how something starting from a stopped position relative to the center of gravity would experience gravity.

Actually, yes it does.

It's not just space that's bent - it's space-[math]time[/math]. An object that is standing still (not moving through space) in any given reference frame is nonetheless moving through time*.

Imagine it like cars, moving at the same velocity along initially parallel roads that bend towards each other - initially, their relative velocity is zero, but as the roads bend towards each other the cars accelerate towards each other.

*It is, literally, moving at one second per second. Or, to be more precise, it has a four-velocity of .

(Note: In this analogy, forwards along the road is time, perpendicular to the road is space, and the motion of the cars is just a way of visualizing their worldline. I realize this is confusing in the same way as the bowling-ball-rubber-sheet model; i'm trying to explain a situation involving space-time but have accidentally included non-analogy time.)

>treating time as a dimension
get out

ding ding dint! First answer, correct answer.

the "electromagnetic field" is actually a misnomer when describing the electromagnetic force. The actual field is the photon field. The field values and such are solutions to a particular differential equation. Electrically charged fields act as a source for the photon field, changing its local properties.

The curvature (geometric property) of the photon field is an anti-symmetric tensor whose components are the electric and magnetic fields. These components are called fields but they are not fields in the same way that the photon is. It's just nomenclature.

So electrically charged particles change the local values of the photon field, altering its curvature and producing electromagnetic forces that act on other electrically charged particles.

yea we're working on that thanks

>This is actually one idea - although you won't find it in textbooks as the concept of an aether has for some reason become taboo.

It's not a taboo. Aether is old model that has been disproved. en.m.wikipedia.org/wiki/Michelson–Morley_experiment

Robert B. Laughlin, Nobel Laureate in Physics, endowed chair in physics, Stanford University, had this to say about ether in contemporary theoretical physics:

It is ironic that Einstein's most creative work, the general theory of relativity, should boil down to conceptualizing space as a medium when his original premise [in special relativity] was that no such medium existed [..] The word 'ether' has extremely negative connotations in theoretical physics because of its past association with opposition to relativity. This is unfortunate because, stripped of these connotations, it rather nicely captures the way most physicists actually think about the vacuum. . . . Relativity actually says nothing about the existence or nonexistence of matter pervading the universe, only that any such matter must have relativistic symmetry. [..] It turns out that such matter exists. About the time relativity was becoming accepted, studies of radioactivity began showing that the empty vacuum of space had spectroscopic structure similar to that of ordinary quantum solids and fluids. Subsequent studies with large particle accelerators have now led us to understand that space is more like a piece of window glass than ideal Newtonian emptiness. It is filled with 'stuff' that is normally transparent but can be made visible by hitting it sufficiently hard to knock out a part. The modern concept of the vacuum of space, confirmed every day by experiment, is a relativistic ether. But we do not call it this because it is taboo.[9]

consciousness explains the force between electrons and protons. consciousness transmits this force. emotional energy binds all things in the meta universe.

That's fair, but the relativistic ether also lacks extremely important properties intuitively implied by the idea of a special substance or medium pervading all of space, and which were critical parts of non-relativistic ether models. Space in general relativity could indeed be called an ether; but by the same definition, so could the electromagnetic field in Maxwell's laws.

>Takes the time to crappily explain how a turbine works to use as demonstration for his point.

wrong. qualia is experienced in the astral plane. it is only in astral-physical plane that our consciousness exists

>Aether is old model that has been disproved
lol no

The strings of the gravitons are not bound to the fabric of space time like the strings of electromagnetic force, strong force and weak force are. This allows gravitons to escape off into other dimensions, explaining why gravity is so much weaker than the other forces.

faulty experiment and has nothing to do with aether lol

>faulty experiment
if you say so..........

Quantum electrodynamics: photons are exchanged between particles creating the coulomb force.

Quantum flavordynamics: pions are exchanged between particles within a close proximity of each other creating the weak interaction.

Quantum chromodynamics: quarks experience color Change do to the exchange of gluons thus creating the strong interaction.

It's up to you wether you take this as fact or not as quantum mechanics is very controversial between physicists.

>God do that
that's shorter and has the same zero meaning

They don't

Last time i heard about it the guy was talking about that shit as something proven. Was it proven? And if it was, why the fuck there is something controversial?

Are forces sweet.

Just because you don't understand something, doesn't mean it doesn't make sense.

I can offer an explanation for your questions, but my explanation will still be prone to questions like "ok, but how does that work?".

Eventually, the answer to this question is simply going to be
>I don't know how or why it works that way. I just know that it works that way, because that's what the evidence says.
Such is the nature of reductionistic explanations.

Quantum field theory. Ignoring some of relativity for the moment, as best as we can determine, reality is made up of a small number of quantum fields. Reminder: A field is simply a thing that exists in every location in space and that has a value (possibly real number values, or vector values, etc.). There is an equation that governs the evolution of these fields over time. The fields interact with each other according to this equation.

A "particle" is simply a vibration, a wave, in the field. An electron is simply a wave in the electron field.

Forces between two normal particles, like a proton and an electron, can instead be thought of as lots of interactions via "force-carrying" particles in another quantum field.
