Captainzen Posted March 30, 2020 Share Posted March 30, 2020 Hello I have read a few topics on gravitational theories. I must state my disagreement on the space warp theory to explain attraction, but I would like to pose a different question. I agree fully on the theory of mass density being the measure of gravitational force. That said, gravity itself is still a mystery. I am talking about the wave that interacts with mass. Like magnetism for instance. We know what a magnetic wave is and how to create it. What efforts are being made to discover the gravitational wave?

Janus Posted March 30, 2020 Share Posted March 30, 2020 We have already detected gravitational waves. However, neither gravitational or magnetic attraction is mediated by waves. A "magnetic wave", is just one component of an electromagnetic wave, or in other words, light and radio waves. Magnetism, as in the attraction and repulsion of magnets, is due to a field, not a wave. 3 Link to comment Share on other sites More sharing options...

What theory would that be? The average density of Earth is about four times as great as that of Jupiter, yet the gravity of Jupiter is nearly three times as great as that of Earth.

Newtonian gravity depends on mass and distance. You could express the mass in terms of a density, but it would also then depend on the size.

In both cases we have theories that describe how they work. Those might also describe "reality" but we have no way of knowing. But kudos for saying "gravitational wave" and not "gravity wave"! 1 Link to comment Share on other sites More sharing options...

At least Captainzen understands the gravitational of the situation... ...and I'll see myself out... Link to comment Share on other sites More sharing options...
