Can Space Appear Curved Due to Forces Similar to Magnetism?

Click For Summary
SUMMARY

The discussion centers on the nature of space and its curvature in relation to gravity, with participants debating whether space itself curves or if the effects observed are due to forces akin to magnetism. Key points include the assertion that curved space-time is a mathematical model used to describe gravitational effects, and that empty space does not curve without the presence of stress-energy. The conversation also touches on the implications of gravitational waves and the mathematical formulations of Einstein's equations in vacuum conditions.

I think the premise is a little off. Empty spacetime does not curve. Spacetime is only curved in the presence of some stress-energy.

Exactly. I think I should note here that actually there is no such thing as empty space. I found my statement on observed cosmic microwave background radiation (CMBR) and continuous particle - antiparticle birth and annihilation throughout all observable universe. If we are to speak of empty space and nothingness or universe beyond observation we are obligated to recognize our action as intrusion into realm of metaphysics.

Acordingly we can develop further understanding of general ralativity and spacetime curvature based on CMBR. I believe we can achieve quite reasonable discription based on that universe has matter/energy all throughout it. It's just that for human point of view (which is traditionan euclidian space) matter/energy is concentrated more in one areas than others - that being planets, stars and black holes opposed to what we call vacuum. As for the spacetime point of view all universe has equally distributed matter/energy all throughout it. Therefore spacetime is not curved in itself. However it appears to be curved for us exactly because we doesn't share the same point of view. Additionally CMBR allows us to bypass earlier problem of explaining presence of gravity in empty space.

Let's conclude: More matter/energy means more spacetime.

(This is why light travels slower in densier and lower energy - temperature close to zero kelvin, materials. It just needs to cover more spacetime.)

Even furthermore we can explain gravitational phenomena using same developments in quantum mechanics. I refer to particle potentionality to be anywhere in space, and that means anywhere with only restriction being speed of light which sets horizon of potentiality. So as for massive objects which has way more spacetime, according to my improvised underlined theorem above, statistically particle has much greater potential to end up in or closer to massive object in space than further away from it. If particle is continuously subjected to such potentiality over time it ends up being pulled closer to object.

This is rather rough outline of my poor understanding of subject, so any discussion is appreciated.
