Do objects moving at faster speeds have a stronger gravitational pull?

Click For Summary
SUMMARY

The discussion centers on the relationship between relative speed and gravitational pull, specifically whether objects moving at higher speeds exhibit a stronger gravitational force. Participants agree that increased relative velocity leads to an increase in relativistic mass, which, according to Newton's law of gravitation (F = G(m1 x m2)/r²), suggests a stronger gravitational interaction. However, they clarify that modern physics does not utilize the concept of relativistic mass in this context, emphasizing the importance of the stress-energy tensor in General Relativity (GR) for understanding gravitational effects. The conversation highlights the distinction between inertial mass and gravitational mass, and the implications for gravitational force as velocity approaches the speed of light.

PREREQUISITES
  • Understanding of Newton's law of gravitation (F = G(m1 x m2)/r²)
  • Familiarity with the concept of relativistic mass and its implications
  • Basic knowledge of General Relativity and the stress-energy tensor
  • Awareness of the principles of special relativity and Lorentz transformations
NEXT STEPS
  • Study the implications of the stress-energy tensor in General Relativity
  • Explore the differences between inertial mass and gravitational mass
  • Learn about the Lorentz transformation and its applications in relativistic physics
  • Investigate the conditions under which relativistic mass is considered in modern physics
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the nuances of gravitational interactions and relativistic effects in high-speed scenarios.

Dale I didn't say anything offensive there.
You can see in the thread itself: https://www.physicsforums.com/showthread.php?t=265994".
I don't try to be offensive.
But I do like to question and not just accept. I don't like to assume something is just right.
When something shows an inconsistency - to me of course - I question it further.

Mentz has made a good effort but we all have to be able to say when we get to the point that we just don't know; even perhaps offer that maybe someone else here may be able to further the topic with more knowledge.

Do you know one of the things I would wish for?
That is an educational site that is evidence data based rather than explanation based.
Surely scientific data can be summarised to show how the broader experiment producing it indicates the principle being tested.

We have our 'thought experiments' but they are no replacement for data that verifies a principle - which of course is what science tries to do. It would be nice if some actual data could be linked with these thoughts.

Those are just wishes of course. I also wish we could all have the toys that the scientists get to play with (I am saying 'play' playfully not insultingly). I have experiments in mind but no easy way to do them. They say 'where there's a will; there's a way' but obviously the will has to be concentrated enough.
