Discussion Overview

The discussion revolves around the relationship between an object's gravity, its density, and its speed as it interacts with the Higgs field. Participants explore theoretical implications and challenge existing understandings of gravity, particularly in the context of general relativity and Newtonian physics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants propose that gravity could be directly related to an object's density and speed, particularly as it passes through the Higgs field.
  • Others argue that gravity is fundamentally linked to mass, asserting that density alone does not influence gravitational force if mass remains constant.
  • A participant suggests that while density affects how close one can approach an object, it does not change the gravitational force exerted by that object.
  • There is a discussion about the implications of replacing massive objects, like the sun, with black holes of equal mass, indicating that gravitational effects remain unchanged at a distance.
  • One participant raises a hypothesis that gravity might be a result of dense matter interacting with the Higgs field, proposing a different perspective on gravitational force.
  • Another participant clarifies that general relativity does not fail at the event horizon of a black hole, but rather at the singularity, which is a common misconception.
  • Several participants emphasize that gravitational force is proportional to mass, and density does not affect it, referencing Newton's theory of gravitation.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between gravity, density, and mass, with no consensus reached. Some maintain that density is irrelevant to gravitational force, while others explore alternative theories linking density to gravity.

Contextual Notes

The discussion includes references to general relativity and Newtonian physics, with some participants acknowledging limitations in their understanding of these theories. There are unresolved questions about the implications of density and speed on gravitational interactions.

my son asked me a question that i can not find an answer too and i hope you can all help me :


could the gravity of a object be directly related to the density and speed of the object as it passes through the higs field ?

I would have thought that gravity is directly related to the density of an object.
As for the speed of an object, well some say the faster an object is moving the more energy it has which they then equate to an increase in mass and hence it will exert more gravity. I'm not a great fan of that idea. If the object is accelerating then that might be a different case, but just simply floating along with a uniform speed I can't see it.
 


According to everything I've studied, the gravitational force produced by an object is directly proportional to it's mass. But I will admit that I have not studied GR, which may have more to say.
 


Density<-- Change this to Mass I guess... And imo and probably only mine density/mass is just how much space it displaces.

I think that density is the wrong word to use here. Just changing an objects density will not change the force of it's gravitational field. If I have two objects with the same mass but different densities then they will both still produce the same gravitational force, as long as the distance does not fall below the radius of the larger object.
 


Right - what density affects is only how close you can get to the [center of] the object. If we're talking about the Earth orbiting the sun, the density of the sun is completely irrelevant. Someone asked the question just yesterday: If you replace the sun with a black hole of equal mass, what happen's to Earth's orbit? Answer: Nothing.
 


Well, except for the part where things get dark and start to get cold about 8 minutes later...
 


hahahah at least that's one thing we don't have to worry about :approve:

the one question that this has raised with my self is , as we currently stand einsteins theories fail at 2 points one being the event horrizon of a black hole the other the big bang.
what if gravity instead of being one of the 4 forces is in fact a result of dense matter passing through the higs field the denser the matter the greater the affect the greater the mass?
 


General relativity actually doesn't fail at the event horizon of a black hole. This is a pretty common misconception. Where GR fails is the singularity of a black hole, and similarly, any proposed singularity at the big bang.

Well many people have studied this, physicists and mathematicians and its shown that gravity is directly proportional to the mass, and density of an object doesn't affect it.
Stated in terms of Newtons theory of gravitation, which isn't a totally accurate description of what's going on but close enough for this.
Gravitational force exerted depends on the mass of the object attracting, the mass of the object being attracted and the distance between them.
