Anything that has mass and occupies space is called matter.
Matter comprises atoms and molecules, which means anything with positively charged protons, neutral neutrons, and negatively charged electrons.
NERVE CELLS ARE The grey matter refers to that part of the neuron not surrounded by the myelin sheath. The nerve cells, cytons, somas, and dendrites are not covered with the myelin sheath, so they constitute the grey matter.
All matter in the world comprises simple substances known as elements made of atoms. All atoms have the same principal components: electrons, neutrons, and protons. Atoms combine to form larger molecules, and elements combine to form larger compounds.
Matter is made up of tiny particles called atoms. These atoms comprise smaller particles called protons, neutrons, and electrons. Protons, electrons, and neutrons in material matter consist of atoms composed of protons, neutrons, and electrons. Both protons and neutrons are located in the nucleus, which is at the center of an atom. Protons are positively charged particles, while neutrons are neutrally charged.
The quantum theory of matter, including nonrelativistic and relativistic quantum mechanics and field theory.
It is genuine news that “quantum physics has confirmed that matter is composed of 99.9999% emptiness.” If anything, my studies suggest the opposite: true emptiness does not exist, not even in the deepest of space in the large voids between galactic superclusters.
The traditional atomic model, with its simplistic depiction of atoms as miniature solar systems, is far from the true complexity of the matter. Understanding the true nature of matter is a captivating journey, a puzzle waiting to be solved that requires us to move beyond these naïve representations. This journey of understanding matter is not just about facts and theories; it’s a thrilling adventure of discovery and the satisfaction of solving a puzzle.
Approximately 55% of the blood in your body is plasma, meaning that plasma makes up around 55% of your total blood volume. Blood comprises plasma (the liquid component) and blood cells (red blood cells, white blood cells, and platelets).
What is an electron, for instance? It is an “excitation of the electron field.” This may sound complex, but let me simplify it for you.
In our best theory, quantum field theory, everything starts with a set of fields: the electromagnetic field, the field of electrons, fields of quarks, gluons, vector bosons, and the Higgs field, all interacting and exchanging energy. These fields are present everywhere. When they interact, they may gain units of energy that we sometimes call ‘excitations.’ An ‘excitation’ in a quantum field is a disturbance or a change in the energy state. For instance, because of an interaction, the electromagnetic field may gain a unit of energy called a photon.
Under the right circumstances, this electromagnetic field excitation may appear highly localized. However, under different circumstances, it may not be localized at all. Either way, this photon is not some miniature cannonball but a property of the electromagnetic field in a specific state.
The same goes for the field of electrons and all the other fields of the standard model, a theory in particle physics that describes the electromagnetic, weak, and strong nuclear interactions using a set of fundamental particles and the forces between them.
So an atom, then, is a collection of a bunch of such excitations—of the field of electrons, fields of quarks, fields of gluons, the electromagnetic field—in a specific configuration. It is neither empty nor full of anything. It is ‘localizable’, which means we can determine its position through interaction. The more powerful the interaction, the more precisely we can pinpoint the atom’s location. However, there are limits: Interact with that atom too powerfully, and you break the configuration, “smashing” the atom.
With the proper experimental design, it is also possible to interact directly with constituent parts of that atom. Interactions with tiny regions can indeed confine these parts. This inspires the intuitive but ultimately false picture that the atom is a small miniature cannonball separated by space. No: The atom is a configuration of interacting fields.
An excitation that corresponds to a genuinely elementary particle, like an electron, can be confined to an arbitrarily tiny volume of space. So, the electron has no size. In contrast, composite things like atoms, protons, and neutrons have a minimum size roughly determined by the interacting fields and excitations that constitute the object.
Now, matter appears solid… However, small or big atoms make no difference. What matters is that atoms, though electrically neutral overall, have a charge distribution that is never perfectly symmetric or uniform. This non-solid nature of matter is a critical concept in quantum physics. When you try to bring atoms together, they might stick together, forming a molecule or repeal each other because of their electromagnetic properties. All this occurs over much greater distances than the sizes we associate with the atom or its constituent bits. So when you cannot push your hand through a solid wall, electromagnetic interactions between the molecules of your body and the molecules of the wall occur, primarily as their electron “clouds” get close to one another and electrostatic repulsion kicks in.
Without interactions, there would be no resistance. Again, matter is not miniature cannonballs that collide or bounce off each other. Those ‘excitations’ of quantum fields could happily travel through one another if the quantum fields in question do not interact, or only weakly interact, with each other. This is why neutrinos, for instance, have no trouble with what. The role of interactions in the behavior of matter is a profound aspect of quantum physics that we should appreciate. These interactions give matter its solidity, resistance, and complexity, and understanding them is a key to unlocking the mysteries of the universe. It’s truly enlightening to comprehend the intricate dance of these interactions in the fabric of our reality.
