Discussion Overview

The discussion revolves around the concept of anti-gravity and the potential for detecting changes in gravitational fields. Participants explore theoretical calculations and experimental claims related to gravity, magnetic fields, and the implications of high-speed rotations on gravitational effects.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant proposes a calculation to explore the possibility of a changing gravitational field producing effects similar to those of magnetic fields, suggesting a hypothetical equation for gravitational effects.
  • Another participant mentions that gravity fields may change frequently, citing neutron stars and black holes as examples where the shape of the gravitational field changes due to mass concentration.
  • A different participant references experiments that reportedly detect changes in gravitational fields when a disk is rotated at high speeds, expressing skepticism about the dismissal of these findings.
  • Concerns are raised about the validity of reported experiments, with calls for peer-reviewed sources to substantiate claims regarding gravitational field changes.
  • One participant expresses doubt about the ability to counteract gravity, noting the uncertainty surrounding its fundamental nature.

Areas of Agreement / Disagreement

Participants express differing views on the detection of gravitational field changes and the validity of certain experiments. There is no consensus on the existence or implications of these changes, and skepticism about the reliability of sources is evident.

Contextual Notes

Limitations include the lack of consensus on the nature of gravity and its effects, as well as the dependence on the validity of experimental reports that may not meet rigorous scientific standards.

Alright, don't take this seriously. This is just a what if situation calculation:
So I was thinking. Atoms possesses charges. Particle possesses 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 :smile: : 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?

We need SpaceTiger or one of the other cosmologists/astronomers to confirm this, but I believe that gravity fields change quite frequently. Take neutron stars or black holes as an example. While the overall gravitational influence remains the same during collapse, the shape of the field changes due to the mass being more concentrated.
 
This is what blast me. There are various experiments reported that they detect a gravity field change when rotate a disk at very high speed. Yet no one believe them.
 
Where was it reported? PF standards demand that it be in a peer-reviewed journal or something of equal validity. If it's merely on-line or in the back pages of Popular Science, it will justifiably be ignored.

It's in wiki somewhere. It's not a regular report. It's from well known scientist. I'll try to find the link and post it up. However, of course it's been argue and justify as false alarm. I don't buy it though. Some "organization" may send out their scientists to "prove" it wrong. Of course majority of us is no match for their sophisticated knowledge.

Hmm... since nobody knows how gravity works, it's a certainty that nobody knows how to counteract it.
