Your idea presents an interesting alternative hypothesis, where space is a fabric-like medium that doesn't interact with matter directly (i.e., no resistance or friction), but instead gets "stretched" by massive objects, altering the paths that particles and light travel along. Let's break this down:

1. Stretching of Space Fabric by Massive Objects

In your model, massive objects (like stars and planets) stretch this space fabric, causing it to become elongated or distorted around them. However, unlike in general relativity where spacetime curvature is tied to gravity, here this stretching wouldn't create resistance or friction for matter and light. Instead, it would just elongate the paths they take.

2. Effect on Particle and Light Speed

In this stretched space, the speed of particles and light wouldn't change (because there's no direct interaction with the medium). However, since the path they travel is longer due to the stretching, it would appear as though light or particles take more time to traverse a region around massive objects. This is similar in some ways to time dilation but operates through the geometry of the medium.

3. Explaining Gravity via Space Stretching

In this model, you could view gravity as the result of objects following the paths created by this stretched fabric. Instead of gravity being a force (as Newton described) or a curvature of spacetime (as in general relativity), it would be more like objects naturally "sliding" along the elongated paths in the space fabric. Massive objects would deform the fabric, and other objects would follow the resulting contours or lines of stretch.

4. Absence of Direct Interaction with Space

A key feature of your idea is that space itself doesn’t directly resist or slow down objects—unlike, say, how air or water interacts with a moving object. Instead, the stretching of the space fabric creates the geometric conditions for how objects move. This means that particles and light move at the same speed through space, but their paths are altered by the stretching. This could explain gravitational effects without needing to invoke an interaction between space and matter (no friction, resistance, or energy loss).

5. Movement Toward Massive Objects

Because the space fabric is stretched around massive objects, the natural path of least resistance (in terms of distance) would lead particles and objects to follow the stretched lines, appearing as though they are moving toward the object. This could serve as a conceptual explanation for why objects "fall" toward massive bodies (like how Earth falls toward the Sun, or objects fall toward Earth).

Summary:

This model resembles some aspects of general relativity, but instead of thinking in terms of curved spacetime and geodesics, it posits a stretchable but non-interacting medium that guides the movement of particles and light. It's an intriguing concept that could offer a different framework for understanding motion and gravity.
