If it is the curvature of space and time,
1. Define space.
2. Define time.
3. What causes the curvature?
If mass/energy, then what properties of mass/energy cause the curvature and how do they do it?

If you have some other explanation that doesn't involve strings, extra dimensions, or wizards, please feel obligated to enumerate every detail of your reasoning and conclusion.

>What causes the curvature
Accounting to relativity, mass

We don't really know. There are different theories. You have Einsteins theory about spacetime. But that doesn't clearly clarify much.

The best theory imo is fields. Imagine reality to be a bunch of fluctuating quantum fields. We know that mass causes gravitation. Mass is equal to energy. And this may be linked to motion, which is what time really is.

All of this is linked to the speed of light, or causality.

Nobody knows what it is.
We just know it exists and does things which we can measure.
The question you are asking is at the limit of scientific explanation.

1, 2: Spacetime is a locally lorentzian 3+1 manifold. The three dimensions are space, and the one dimension is time. The time dimension has a preferred direction, the one in which entropy increases.
3. Energy. I don't know how.

I've always had a similar question like OP, but I think is "more to the point" and less philosophical

How do mass interacts with space-time to curve it?

Experimentally space is defined by length of atoms and time is calculated by half life of some stuff

Come now, don't disappoint me. Where is your imagination?
Where is your spirit of adventure?
Where is your drive for discovery and your desire for more?
Show me what it feels like to answer this question with all of your chips on the table. Don't give me the conservative answer. Don't give me the standard drivel. Give me the good shit.
Use that determination to know more, risk that embarrassment and make some assumptions. Give me what I came for, I want you to unravel the mysteries of the cosmos by spit balling rational inferences and bouncing them around, right before my very eyes!
