@shockwave326 We know time dilation works. Particles at high speeds decay more slowly. Does electric universe explain that?

Could weight be thought of as an apparent force? Centrifugal force is not a real force, but we can calculate it, measure it, etc. Not to say that weight has anything like the same cause as centrifugal force, of course.

@frankdimeglio8216 i think YouTube thumbs up don't have quite the weight as peer review.

They're only locally equivalent.

We don't know everything that makes it work, but we can observe it working.

I think this is where gravity and acceleration are only locally equivalent. A point particle couldn't tell the difference between the two at any instant, but you're large enough to have (very small) tidal effects. I could be 100% wrong though.

@En_theo That's where the locality matters, I think. It's not that the tidal force is tiny, it's that for a point mass there wouldn't be that difference. I think.
