Physics of Superheroes




In the past, I posted about the Physics of Spiderman 3, Superman

Today, I present in this blog a paper about Physics and Superheroes.

The Standard Model

Standard Model - Source: Wikipedia


 The Standard Model of particle physics is the theoretical framework that describes the fundamental building blocks of the universe and the forces through which they interact. It is one of the most successful and rigorously tested theories in modern physics.

Here is a breakdown of how the universe is put together according to the Standard Model.

1. The Building Blocks: Matter Particles (Fermions)

All tangible matter in the universe is made up of particles called fermions, which have half-integer spin (e.g., 1/2). These are divided into two main categories, each split into three "generations" of increasing mass.

Quarks

Quarks are heavy particles that experience the strong nuclear force. They combine to form composite particles called hadrons (like protons and neutrons).

  • Generation 1: Up (u), Down (d) — These make up ordinary stable matter.

  • Generation 2: Charm (c), Strange (s)

  • Generation 3: Top (t), Bottom (b)

Leptons

Leptons do not feel the strong nuclear force.

  • Generation 1: Electron (e-), Electron Neutrino (νe)

  • Generation 2: Muon (μ), Muon Neutrino (νμ)

  • Generation 3: Tau (τ), Tau Neutrino (ντ)

Note: For every matter particle, there is a corresponding antimatter particle with the same mass but opposite electric charge (e.g., the positron is the antielectron).

2. The Messengers: Force Carriers (Gauge Bosons)

Particles interact by exchanging force-carrier particles called gauge bosons, which have integer spin (e.g., 1). The Standard Model accounts for three of the four fundamental forces of nature:

ForceDescriptionGauge Boson (Carrier)Mass / Range
ElectromagnetismGoverns atomic structure, light, and chemical reactions.Photon (γ)Massless / Infinite
Strong Nuclear ForceBinds quarks inside protons/neutrons and holds atomic nuclei together.Gluon ($g$)Massless / Short-range
Weak Nuclear ForceResponsible for radioactive decay (like beta decay) and initiating solar fusion.W+ / W- and Z0 BosonsVery heavy / Ultra short-range

3. The Mass Giver: The Higgs Boson

The Higgs Boson (H) is a scalar boson (spin 0) associated with the Higgs field, which permeates the entire universe.

  • Mechanism: As fundamental particles move through this field, they interact with it. The strength of this interaction determines the particle's inertial mass.

  • Particles like the top quark interact strongly and are very heavy; photons do not interact with it at all and remain massless.

  • Its discovery at CERN's Large Hadron Collider (LHC) in 2012 was the final piece confirming the Standard Model's framework.

What the Standard Model Left Out

While incredibly robust, the Standard Model is known to be an incomplete theory of nature because it fails to explain a few massive cosmological puzzles:

  • Gravity: It does not include general relativity. The hypothetical carrier of gravity, the graviton, has not been incorporated mathematically into the quantum framework.

  • Dark Matter & Dark Energy: The model only accounts for about 5% of the energy-mass composition of the observable universe. The remaining 95% is completely unaccounted for.

  • Neutrino Mass: In the original mathematical formulation of the Standard Model, neutrinos are massless. However, oscillation experiments have proved they possess tiny, non-zero masses.

  • Matter-Antimatter Asymmetry: It doesn't fully explain why the universe today is overwhelmingly made of matter, even though the Big Bang should have produced equal amounts of matter and antimatter.

Eggnaut challenge

 

Eggnaut protection created with Gemini

One of the students’ favorite challenges is the Eggnaut experiment. In this activity, they use the physics learned in secondary school along with engineering, management, economics, and other skills to create a cost-effective solution to protect the egg.

Jupiter code about the Hellium Chewing Gum

This post (from 2010!) explained the Physics behind a fake video.

There wasn't AI to  try to explain the phenomenom. But we have it today. So I took all the Physics and put it in a Jupiter file available here: Simulations/helium gum exp.ipynb at main · eufisica/Simulations

By the way, the new website is ready and available here: EUFISICA.
