The universe is fine-tuned for the existence of life. Only a tiny subset of the laws of nature allows for intelligent life. Known-thought reposers, be us. There are seven natural laws through which everyone and everything is governed. They are the laws of Attraction, Polarity, Rhythm, Relativity, Cause and Effect, Gender/Gustation, and Perpetual Transmutation of Energy. The four fundamental interactions or forces: gravitation, electromagnetism, weak interaction, and strong interaction.
There is nothing simple about life. Millions of carefully coordinated chemical reactions occur every second inside a single cell; billions of single-celled organisms can organize into colonies; trillions of cells can precisely stick together into tissues and organs. Foundational physical principles underlie all life forms. Biological living systems are in a completely different class compared to physics. The biological complexity and the degrees of freedom, and. The living active matter state.
Life is chemistry. Chemistry provides information on the molecules needed to make life. Living organisms are condensed-matter systems with thermodynamic constraints. Traits of life, such as replication, evolution, and using energy to move, are examples of “emergent phenomena.” A cell is the smallest unit of a living thing.
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an essential component of the cell and performs a wide array of functions.
Cells are the basic building blocks of all organisms. Several systems that function together form an organism (like a human being).
Cells are the fundamental working units of every living system. All the instructions needed to direct activities are contained within the chemical DNA. DNA from all organisms is made up of the same chemical and physical components. DNA is the code of life. It is a code containing instructions on building various proteins and protecting and maintaining the cell’s structure. DNA also moves cargo around within the cell; it also helps the cells communicate with and signal to other cells. Randomness didn’t do the build-out on life.
Cells have metabolic enzymes that break down proteins, fats, and sugars into energy packets that can be used to build and regulate the cells. They also self-replicate. Randomness? Hell, no.
The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.
The physics relevant to life is low-energy physics. Quantum physics allows for entirely different phenomena than classical physics. They are allowing for the collective quantum mechanical coherence between particles. The individual particle sacrifices its identity for the group’s joint motion—new types of excitations result. Electrons in systems where the action is confined to a plane can act as a quantum liquid with peculiar properties. Coherent effects in low-dimensional electron systems cause High-temperature superconductivity. Quantum mechanics also provides additional ways to treat and send information.
High energy physics (also known as particle physics) involves the most fundamental building blocks of matter and understanding these particles’ interactions. The goal of high-energy physics is the understanding of the elementary particles that are the essential constituents of matter.
The formation of simple prebiotic organic compounds on early Earth is an essential step in life’s origin. Molecular dynamics simulations of cometary ice conditions during planetary impact suggest a possible mechanism for glycine formation, an amino acid.
