Fuzzy Atoms

Atoms are fuzzy little bundles of energy. And how that energy moves around, interacting with itself and other atoms, is much more complicated than you probably realize. Only when you see how blurry atoms are will you be able to see them clearly. I'll explain what I mean in this video.

Atoms are composed of protons, neutrons, and electrons. Protons and neutrons are further made up of quarks. Thus, atoms are ultimately made up of the smallest pieces of stuff known as quarks and electrons. You've probably seen images of these things as small spheres vibrating and orbiting one another. However, that image is misleading at best and completely wrong at worst.

Scientists don't know what quarks and electrons are made of or how they look because they are made up of energy, and they don't know what energy is. At the moment, the best explanation is that quarks and electrons are disruptions in quantum fields. So, what does this mean?

This line represents the energy of a quantum field. Until a quark enters the picture, the energy remains constant. The squiggly part of the line represents how the quark disturbs the field. If the line had represented a humidity field, it would mean that the humidity was consistent throughout an area, whereas the squiggle indicates that it deviated from the norm in that location. It could appear that way if a cloud were passing by.

However, the undisturbed field isn't exactly a flat line as I showed. Whether for a humidity field or a quantum field, it is much more like an undulating landscape with constant jiggling as background noise. Quantum fuzziness is a term used to describe this activity in a quantum field. Thus, a disruption in a quark field would appear more like a big bump with a lot of background noise around it.

Each type of fundamental atomic disruption is assigned to a distinct field. So quarks disrupt the quark quantum field, while electrons disrupt the electron field. As a result, quarks and electrons aren't little spherical particles that buzz around each other. They are the chaotic bundles of energy in their respective fields. And the disruptions are dynamic fluctuations. Nothing at the macro scale is an accurate representation, but they may resemble the audio signal of your voice in an air-pressure field.

However, this is only one of the reasons why messy quarks and electrons result in fuzzy atoms. Another quantum field is involved, which contains disruptions known as gluons. Gluons bind protons and neutrons together by transferring color charge between quarks. The quarks constantly flip the three color charges of blue, green, and red, which have nothing to do with rainbow colors. They are just given these somewhat arbitrary names.

Electrons are disruptions in the electron quantum field, completing the atom. Thus, several quantum fields are involved, each of which is constantly in flux. However, it is still more complicated because some of the fields interact with one another, changing their already chaotic activities. Quantum physicists are still conducting experiments and using mathematical models to decipher the rules for field interactions.

When considering this combination of quantum fields, keep in mind that they are not layered on top of each other like sheets. They all exist in three dimensions that overlap with one another. This is difficult to picture, but you're probably getting a sense of the atom's complexity.

But, wait! There is another crazy aspect to the picture. The fields have some disruptions that spontaneously pop in and out of existence. These disruptions are referred to as virtual because they are unstable and last only a short time. You could imagine them as small clouds that appear and disappear around a larger, more-stable cloud.

When all of these activities are combined, it's difficult to believe that an atom could exist at all. Despite the messiness, atoms are generally stable, and the majority have remained in their current energy configurations since they were first formed billions of years ago. And they become even more stable when combined into larger structures known as molecules.

Perhaps you can see fuzzy atoms more clearly now. When you consider how bizarre the universe's building blocks are, it's incredible that you and I exist at all.
