Hey /sci/ brainlet here.
Considering that gravity is due to the deformation of space-time, is gravity really a force?
>>8829235
It technically is not.
>>8829235
Gravity isn't anything. It dosn't exist.
>>8829235
What's actually happening is that as vacuum collapse occurs and the amount of matter in the universe decreases the gravity of the celestial body can now overcome the vacuum/zero point energy of space-time, bending it.
Observable gravity is proof that the end of the universe, false vacuum collapse is occuring.
>>8829235
So as more and more false vacuum quantum tunnels into a lower energy state, releasing a vast amount of energy from the vacuum it will destroy more and more of space-time and matter with it.
Eventually, the universe will lack in vacuum energy, matter; dark matter and dark energy causing gravity to overcome all and collapse the universe into an infinitely dense point.
Perhaps restarting the universe?
>>8829235
No
Something something General Theory of relativity. Space and tie is warped or some shit

We don't actually know what gravity is, enjoy your rough analogies.
>>8829235
the closer higgs bosons get to each other the smaller they get and the slower they travel through time. gravity is the resistance to reinflation/temporal acceleration of higgs bosons exibit.
>>8829235
So bottom line nobody knows, but "space curvature" is a useful analogy and also works mathematically.

>>8829235
It's geometry m8.

Without gravity the universe would literally be a sparse cloud of hydrogen and nothing else. Observable gravity is an indicator of quantum vacuum decay as much as breathing is an indicator that you are going to die some day. Get the fuck outta here on that high horse you mongoloid brainlet.
The apparent force is when you try to resist the acceleration of gravity. Gravity is above all an acceleration. DESU all forces might just be accelerations. Force and acceleration are pretty much indistinguishable.

Why would you lie on the internet?
>>8831945
Because it's fun detecting the brainlets who actually take it for srs bizzness.
>>8831960
How does that detect brainlets? Portraying a brainlet perfectly and getting called out on it speaks more to your very limited necessary ability to act through text than it does anyone else's intelligence.
Gravity is density

Yes, 'tis. And you would realize that fact if you weren't a terminal brainlet.

A field theory describes the relationships that the points in this field have in space and time. General relativity is a classical field theory, so think of F = ma. As you can see, force is related to acceleration.
If we consider the relationships between frames of reference in this field which are accelerating, there is a distinct relationship between the accelerations of these frames and the matter that resides within them. These sort of relationships are what Einstein's field equations describe.
For general relativity in particular, these relationships describe what we know as gravity. Geometrically speaking, if we consider a space-time geometry composed of these frames of reference as aforementioned, the difference in the accelerations of frames can be thought to "curve" this geometry. That curve/difference in accelation, is gravity. In this consideration, it isn't a "force," but rather a property of geometry. However, neither can the forces which we describe using quantum field theories be considered forces.
We pick and choose what we call a force depending on the context at hand, because gravity has no quantum field theory as of yet. If we're considering the force of gravity, we're not concerning ourselves with the strong force in the same sentence.
