Alright, don't take this seriously. This is just a what if situation calculation: So I was thinking. Atoms possess charges. Particle possess mass. Charges produce electric field while mass produce gravitational field. A changing electric field produce a magnetic field. What unique about electric and magnetic field is that, to me, it's the same field of anti direction. If you charge a pole positive 1 side and negative on the other, the field is strictly inside the pole. Magnetic field effects outside the pole. Anyway, I was wondering if a changing gravity field produce anything similar. So far we ain't detecting anything that we know of. lol So I thought "maybe it's too little to detect". So i start doing calculation similar to magnetic field to see if it's inside or outside of our detecting scope. magnetic equation: B=u0I/(2piR) where u0=magnetic constant I=current R=radius of wire "magnity" equation :rofl: : GZ=kv/(2piR) k= some constant v=velocity R=radius of pipe . similar to u0 calculation, I calculated k=1.67 x 10^-7 (standard metric units) Let's a sume I have a pipe with water inside. The pipe diameter is 1m. I want to experience a GZ of 1m/s^2 (aobut 1/10 of earth gravity). The calculation come out to be v=1.88x10^7 m/s . Approx 6% speed of light. I conclude that it's outside of our detection. What do you think?
