I don't actually know what the higgs field is. I assumed it was gravity.

I don’t actually know what the higgs field is.

I wouldn't be comfortable getting into the details of the actual "Higgs field" is, nor the Higgs boson, as I am not confident in my understanding, but, for the sake of the meme, the following excerpt from Wikipedia should suffice:

via the Higgs mechanism, [the Higgs boson] gives a rest mass to all massive elementary particles of the Standard Model, including the Higgs boson itself. [source]

I assumed it was gravity.

Gravity can be understood as the attractive force that two massive objects impart on eachother [1.1] ­— the strength of the gravitational force imparted by one object onto another is proportional to the mass of the former object [1.2]. Do note that this is a simplification. Gravity, as far as it is currently understood, is quite a bit more complicated than this (I am primarily referring to General Relativity) [1].

    1. gravity is a fundamental interaction primarily observed as mutual attraction between all things that have mass.

    2. $$F = \frac{Gm_1m_2}{r^2}$$ where $F$ is the force, $m_1$ and $m_2$ are the masses of the objects interacting, $r$ is the distance between the centers of the masses and $G$ is the gravitational constant

Oh so it's all of it. Got it.

To make it as simple as possible, Higgs makes it hard to push something. Gravity makes it hard to lift something.

So there are actually two types of mass. One is called inertial mass (what we feel due to the Higgs mechanism) and the other is called gravitational mass (what we feel due to gravitational attraction between two masses). They are usually the same so the distinction is usually ignored.

Too simple, imo. It simplifies to the point of becoming incorrect.

Higgs makes it hard to push something.

One is called inertial mass (what we feel due to the Higgs mechanism)

The Higgs mechanism has been found to give mass to elementary particles only (short of neutrinos) [3]. This is important to note, as the mass of hadrons is far larger than the sum of their constituent elementary particles [4]. The rest, and vast majority, is found in the bound energy (eg the Strong Interaction) of the elementary particles (eg quarks) [1][2].

Regarding "Inertial mass", I want to note the following definition for clarity:

Inertial mass is a measure of an object's resistance to acceleration when a force is applied. [5]

It's not the Higgs field. The Higgs gives elementary particles their masses. The strong interaction gives protons and neutrons their masses. There is a whole lot of energy bound up in those protons and neutrons. That's why protons and neutrons are considerably more massive than than the sum of the masses of the quarks that form them.

QCD energy binding (associated to a "cloud" of gluons joining together the three quarks) is responsible for the 99% of the inertial mass of a proton.

the Higgs field is responsible for the masses of all the elementary particles (including the Higgs boson) short of neutrinos.

Actually, it’s closer to 99% when it comes to protons and neutrons. Only about 1% of their masses come from the up and down quarks; the rest is binding energy.

Higgs makes it hard to push something. Gravity makes it hard to lift something.

The Higgs interaction contributes to both. Mass due to the Higgs interaction is a component of inertial mass, given that the Higgs boson gives mass the elementary particles contained within [3]. Inertial mass is a measure of an objects inertia (ie its resistance to acceleration when a force is applied) [1][2].

Note that the concept of "lifting" only applies in a gravitational field when a force is able to be created by pushing off of a surface — the resistance to the "lift" being created by the objects weight. If one is in free-fall, for example, the effects of gravity are no longer apparent given that one has no reference to the fact that they are falling.

Inertia is the tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes its speed or direction to change.

The Higgs gives elementary particles their masses.

the other is called gravitational mass (what we feel due to gravitational attraction between two masses).

I'm not sure exactly what you are trying to say here, but I suspect you are perhaps referring to the following excerpt(s) from Wikipedia:

Active gravitational mass is a measure of the strength of an object's gravitational flux [1]

Passive gravitational mass is a measure of the strength of an object's interaction with a gravitational field. [1]

I've personally never heard the term "gravitational mass" before, but it could be found from the above two statements, or more succinctly stated:

Gravitational mass is the "m" in F = GmM/r2 (Newton's law of universal gravitation) [2]

They are usually the same so the distinction is usually ignored.

This statement is rather dubious. Simply put, there has simply not been found any empirical difference between inertial mass and gravitational mass. [1]

Thank you for the lesson :)

The Higgs mechanism has been theorized to give mass to elementary particles [1]. That is not to say that the total of inertial mass of a non-elementary massive object is due to the Higgs Boson.

References"Higgs Mechanism". Accessed: 2024-08-13T07:13Z. Wikipedia. https://en.wikipedia.org/wiki/Higgs_mechanism

the Higgs mechanism is essential to explain the generation mechanism of the property "mass" for gauge bosons.
