Discussion Overview

The discussion revolves around the perceived weakness of gravity compared to other fundamental forces, such as electromagnetism and nuclear forces. Participants explore various perspectives on the nature of gravity, its relationship with matter, and potential comparisons with other forces, incorporating theoretical and conceptual considerations.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant suggests that gravity's weakness can be illustrated by comparing it to the force of a magnet lifting a paperclip, proposing a relationship between gravity and the amount of matter present.
  • Another participant questions the premise of gravity's weakness, arguing that it may not be abnormal for gravity to have its current strength given the lack of understanding about its nature.
  • A participant reflects on the idea that matter creates energy by attracting smaller objects, questioning whether gravity could be comparable to electromagnetism and nuclear forces when considering all atoms in the universe.
  • One reply discusses the conservation of energy and potential energy in relation to gravity, suggesting that the relationship between gravity and other forces is a current hope in physics.
  • Another participant introduces the concept of natural units, proposing that the question of gravity's weakness might be reframed in terms of the mass of a proton compared to its charge, suggesting a different perspective on mass and force.

Areas of Agreement / Disagreement

Participants express differing views on the nature and strength of gravity, with no consensus reached. Some challenge the notion of gravity being weak, while others explore its implications and relationships with other forces.

Contextual Notes

Participants acknowledge the complexity and unresolved nature of gravity, with references to theories such as supersymmetry and the conservation of energy, indicating limitations in current understanding.

So I have come to a conclusion regarding the weakness of gravity, but i myself am uneducated when it comes to the theory of relativity, so I will just go ahead and state 1 example and my suspected reason gravity is so weak. We know that a 1cm spherical magnet can break the force of gravity when a paperclip is lifted from the ground via a magnet. I also know gravity is directly tied in with matter, more matter will affect matter itself, so if there was a constant force measurability I.E. power amongst a force- How much "gravity (or matter currently spread out)" is needed to combat any other of the 4 forces at comparison. That is the question, now I'm thinking it would be an argument between superconductivity conditions of electrical magnetism, or with the nuclear forces how much gravity is needed to actually affect a nuclear property.
 
Physics news on Phys.org
What?
 
Nothing new and many amiss.
 
Why should gravity not be weak?
Is that even a correct question - why is it weaker than others?
Since no one have a clear idea what gravity is, why assume it's unnormal that it's as strong as it is?
 
Artlav you have arisen a good point, no one knows what gravity is and you have helped me understand something very important, matter itself, in the form of an atom(s) actually creates energy by pulling in smaller objects. this means gravity being expressed as I was thinking - a measurable form of energy, is distinctly different from a measurable form of of energy contained in matter- ie strong or weak nuclear, or electromagnetism, now what I was trying to get at in my first post, are these all relate-able? would the force of gravity made up of all the atoms (before they were spread out) in the universe contain enough force to be equal to electromagnetism and the nuclear forces. Thinking this last statement is true is what got me on here in the first place, it really intrigued me.

Energy, unlike mass, is conserved; You cannot create or destroy energy. Also, if you have two masses far apart, they have more energy than when you bring them closer together (potential energy).

are these all relate-able
That's the hope of physics ATM.

would the force of gravity made up of all the atoms (before they were spread out) in the universe contain enough force to be equal to electromagnetism and the nuclear forces
Depends if super-symmetry holds. Otherwise no, and even if super-symmetry holds... it's broken... so no.

Creating energy, wow. Really, finally someone broke the law of conservation of energy.

Honestly the energy was there all along. It's just the form that changes.
 
As much as I know about gravity, it is a long range, extremely weak force(compared to others).

Since according Newton,s universal law of gravitation gravitational force
F=Gm1m2/R2

It looses its strength totally even in short distances.
(though there are black holes which possesses great gravitational energy... but in daily day life gravity isn't that strong!)
 
if you look at the question in natural units, rather than SI, it's nature changes from "why is gravity weak" to "why is the mass of a proton so small compared to it's charge?" If you compare gravity to, for example, radiative energy or steller wind, it's comparable... both vary with the square of distance for a given receptor... though for the others, it's surface area rather than mass that changes. So, perhaps mass should be thought of as the "surface area" of an object from a different n-dimensional angle... then the question would disappear all together.
