So gravity doesn't actually exist, there's just the warping of space-time?

Anonymous No. 16473629

Nah spacetime doesn't warp. An expanding universe with constant dark energy density breaks the law of conservation of energy so it can easily be discarded

And when they talk about dark energy they mean that empty space is expanding. The galaxies are all moving away from each other but it's not them moving in the traditional sense, it's space between them. And the expansion is accelerating. What accelerates as it moves? The warping of space-time.

Conservation of energy is a local law, it does not have to hold on the scale of the (expanding) universe.

It either holds or it doesnt hold. There is no such thing as "local". 50/50.

Energy is relative and local, an example being red shift causes photons to drop in frequency and lose energy.

Pretty fucking stupid comment to be quite honest it's like saying to try use QM to determine what happens at a galatic scale when it only occurs at a sub-atomic level.

what happens at the tiniest scale should be the same as what happens on a galactic scale. Right now, our understand is shit so they don't match up.

The 4 fundamental forces of the universe should act on everything equally no matter how big it is. But they don't for some reason. Why? We don't know, lol.

Yes it does

Spacetime is a mathematical model, a coordinate system comprised of three spatial and one time coordinate, the "warping" of spacetime is not gravity, rather gravitic effects lead to changes in coordinates, which can be mapped out using spacetime.

Einstein did not believe that.

A first order expansion of the Einstein field equations and the geodesic equation, ignoring higher order curvature, generates Newtonian gravity. Newtonian gravity is a fictitious force caused from our assumption that our background is static.

It well documented. He initially thought it was simply a mathematically shorthand but he came to change his mind while developing GR.

Proof is that big things are made of smaller things.

What came first:
The Mass or
The Spacetime or
The Curved Spacetime

You claim curved space time exists,
but Spacetime is not assumed to curve of its own volition.
And if that is so,
Space time must be curved
And if that is so
Spacetime must be forced to curve
And if that is so
It must be mass that forces space time to curve
And if that is so
Mass must accelerate Spacetime from a non curved to a curved formation
And if that is so
A Mass in the vicinity of Spacetime-forced-to-curve will be forced to accelerate by the accelerated-spacetime-forced-to-curve-by-mass
It seems this is so
