C = Speed of causality (otherwise known as speed of light)

What if the speed of light really is something different and we just experience it this way?

Consider the following world:

In a far distant universe things are different. Distances between objects are measured not spatially, but as space-time vectors which denote how far spatially and how far in time the events differ. This unit of measurement is more more useful since someone who stays still still moves at v=c in a completely vertical line parallell to ct.

Now if all that is clear, consider the following absurd difference. Rather than flat 4D Space you are working with round hyperspheres. What this really means is locally, you can travel in a straight line but in flat spacetime we percieve this as a circlular motion. Consider an orbiting object, it is moving in a circular path. To stay in orbit you need an attractive force towards the center of the object you orbit around F = mg as well as a velocity that escapes the ground quick enough let's set it to v = 10 000m/s.

In curved spacetime, this circular path is actually straight. Because the unit you measure a straight line with is circular, all circular paths are also straight paths. Now to blow your mind even further, what is F=ma really doing? A free falling object that circles the object itself travels at a straight path which means it is actually not experiencing any acceleration. This means the force F=ma is not needed if we assume the curvature is affected by the mass of the object. Gravity can manifest itself as something that bends spacetime in order for people to agree on what an inertial frame of reference really is.

Now to blow your mind with facts some facts.
In flat space and time, or even just flat spacetime observers do not agree about:
- Distance between things (spatial difference)
- Distance between events (time difference)
- Order of events (past, present future)

How do you calculate the volume of space-time displaced by a mass?

Mass curves spacetime like a ball curves a trampoline . and your question makes no sense. Mass bends spcetime becouse universe works like that. Why do protons pull electrons , why is the speed of light is the limit . These questions have no answers
