    Baryons
In summary, The possibility of two gravitational forces, one for leptons and one for baryons, was recently mentioned in NewScientist. However, there is doubt that physicists are giving it serious thought as the article was lacking in details and references. Furthermore, the idea has already been ruled out by data in 1890. This was merely a letter to the editor and may have been dismissed if posted on a more reputable platform.

There was something in last week's NewScientist about the possibility that there are two gravitational forces, one for leptons and one for baryons. Are physicists giving this serious thought?

I doubt it. The article was awfully skimpy on details - like a reference to a real paper, or even a name. Just some anonymous "scientists".

The possibility of leptons and baryons having significantly different responses to gravity was ruled out in 1890 by Lorand Eotvos.

Interesting idea though newscientist

Why is an idea excluded by data "interesting"? Would the idea that apples fall up instead of down be interesting?

This isn't even an article, it's a letter to the editor. If he had posted it here on PF, without any references to show that physicists are actually discussing this possibility seriously, we probably would have deleted it as being overly speculative.
 

1. What is the difference between leptons and baryons?

Leptons and baryons are two different types of subatomic particles. Leptons are elementary particles that do not experience the strong nuclear force, while baryons are composite particles made up of three quarks. This means that leptons are fundamental particles, while baryons are made up of smaller particles.

2. How is gravity different for leptons and baryons?

According to the theory of general relativity, gravity is a result of the curvature of space-time caused by the presence of mass or energy. Since leptons and baryons have different masses, their gravitational pull will be different. However, the difference in gravity is too small to be measured with current technology.

3. What is the significance of having different gravities for leptons and baryons?

The difference in gravity between leptons and baryons is significant in understanding the behavior of subatomic particles and their interactions with each other. It also plays a role in the formation and evolution of the universe, as the distribution of matter and energy is affected by gravity.

4. Can the difference in gravities for leptons and baryons be explained by the Standard Model of particle physics?

The Standard Model of particle physics does not provide a complete explanation for the difference in gravities for leptons and baryons. While it does predict the masses of these particles, it does not fully explain the origin of mass itself, which is necessary to understand the difference in gravity.

5. Are there any experiments being conducted to study the difference in gravities for leptons and baryons?

Currently, there are no specific experiments being conducted to directly study the difference in gravities for leptons and baryons. However, scientists are constantly working on improving our understanding of the fundamental forces and particles, which may lead to future experiments that could shed light on this topic.
