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 (ν_e)

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

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

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:

Force	Description	Gauge Boson (Carrier)	Mass / Range
Electromagnetism	Governs atomic structure, light, and chemical reactions.	Photon (γ)	Massless / Infinite
Strong Nuclear Force	Binds quarks inside protons/neutrons and holds atomic nuclei together.	Gluon ($g$)	Massless / Short-range
Weak Nuclear Force	Responsible for radioactive decay (like beta decay) and initiating solar fusion.	W+ / W- and Z0 Bosons	Very 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.

The Scale of the Universe

Scales in the Universe - Created with Gemini AI

 The scale of the universe is so vast that our everyday units of measurement completely break down. To comprehend it, physicists and astronomers look at the universe across orders of magnitude, moving from the microscopic quantum realm up to the edge of everything we can see.

1. The Microscopic Limit: Quantum Scale

Before looking outward, understanding the absolute smallest limits of space helps frame the true extremes of scale.

• The Planck Length (1.6 x 10^-35 m): The theoretical smallest possible distance in physics. Below this scale, the traditional concept of space and time ceases to exist.

• Subatomic Particles (10^-18 m to 10^-15 m): Quarks and electrons have no measurable size, but a proton or neutron spans about 1 femtometer (10^-15 m.

• The Atom (10^-10 m): An atom is roughly 0.1 nanometers across. If an atom were magnified to the size of a massive sports stadium, its nucleus would only be the size of a marble in the center.

2. The Human and Planetary Scale

Moving up to lengths we can physically perceive, objects grow exponentially as we exit Earth's atmosphere.

• Humans (10⁰ m): Positioned roughly in the middle of the cosmic scale between the Planck length and the observable universe.

• Earth (1.27 x 10⁷ m): With a diameter of roughly 12,742 km.

• The Sun (1.39 x 10⁹ m): Approximately 109 times the diameter of Earth. You could fit about 1.3 million Earths inside it.

3. The Cosmic Scale: Light-Years and Parsecs

Once we leave the Solar System, the meter becomes too small to be practical. Instead, we measure distances by how far light travels in a year (one light-year, or ~ 9.46 x 10¹⁸ m).

• Solar System & Neighborhood: The distance from Earth to the Sun is 1 Astronomical Unit (a.u.)}. The nearest star system to us, Alpha Centauri, is about 4.37 light-years away.

• The Milky Way (10²¹ m): Our home galaxy is a spiral disk roughly 100,000 light-years across, containing hundreds of billions of stars.

• The Local Group & Superclusters (10²³ m): The Milky Way belongs to a small cluster called the Local Group (spanning 10 million light-years), which itself is a tiny branch of the massive Laniakea Supercluster, home to over 100,000 galaxies.

4. The Observable Universe

The observable universe is a spherical region centered on Earth, encompassing everything we can theoretically detect because its light has had time to reach us since the Big Bang.

• The Diameter: While the universe is about 13.8 billion years old, the expansion of space means the edge of the observable universe has stretched farther away. Its current diameter is estimated to be roughly 93 billion light-years (8.8 x 10²⁶ m).

• The Content: It contains up to 2 trillion galaxies and an estimated 10²⁴ stars—more stars than there are grains of sand on all of Earth's beaches.

• Beyond the Observable: Because cosmic inflation expanded space faster than the speed of light during the earliest moments of the Big Bang, the entire universe is likely far larger than what we can observe—and it may well be infinite.

Would you like to explore a specific realm of this scale further, such as the math behind cosmological expansion, or how we measure these immense distances using standard candles?

This video provides an excellent visual journey zooming out from Earth to the edges of the observable universe to help contextualize these massive cosmic distances.
