Eli5 if gravity is an illusion caused by the curvature of spacetime why do we need to reconcile it with the standard mode.

796 views

I have heard it explained multiple time by different science educators that what we feel as gravity is a really just a consequence of curvature of spacetime and no real force is being applied. Why do we need to make gravity work with the standard model, and why are we looking for gravitons if there is no actual force and it is just caused by the geometry of the universe?

Our best description of gravity says:
>mass and energy distort the spacetime, making straight lines bend and accelerate/decelerate.

It doesn’t dive very deep on **how** mass/energy is able to apply this distortion.

To make it very very simplistic currently we are able to predict gravity’s effect on matter, but we are not able to describe its nature.

I mean, if you want to go very phylosofical-junkie you could even say that spacetime is just a mathematical construct, and not something that materially exists. It is a 4d grid that we use to measure the whole universe, but you won’t be able to touch it, or “measure” it.

So there is still much to explore to improve our description of gravity
