According to science, we are a complex system made up of trillions of the smallest living thing on Earth: the cell. We have approximately one hundred trillion of these tiny organisms in our body, most with a life span of between 6 and 8 months. Due to a scheduled “rotation” of new cells replacing dead cells throughout the body, we are, biologically-speaking, a different person very 6 years! This means a person of 72 years has had twelve different bodies in his lifetime!
Of these trillions of cells, only a measly ten percent actually belong to us, or rather, are truly “human.” The remaining ninety percent are “immigrants” known as fungi, mites, and bacteria. Although it may be rather unpleasant to imagine that most of our cells are “alien” to our human bodies, it is important to remember that they are our indispensable partners which work in symbiosis to keep us alive. Additionally, these large numbers of microbes form an impressive ecosystem within our body, and to survive they hunt, eat, kill, and breed — just like any other organisms would in a macro-level ecosystem.
For an ordinary person, the maintenance of this ecosystem requires a huge investment in time and nutrients. For example, if an individual weighs 170 pounds and is 70 years old, he has eaten more than 100 thousand pounds of food, drank over 30 thousand gallons of liquids, and has spent 24 years in bed in order to “recharge his or her batteries.” It may be demoralizing to learn that the return on investment is practically insignificant: The human body is made up of approximately 70 percent water (practically a walking swimming pool!), with the residual 30 percent mainly composed of carbon, nitrogen, and 28 other chemical elements such as calcium, potassium, iron, and even the highly toxic arsenic.
At face value, these compounds are nothing more than abundant and cheap raw materials! What is more, everything in our bodies is ultimately composed entirely of atoms – most of which are actually empty space! To put this into perspective, imagine the nucleus of a Hydrogen atom as a solid sphere and its electron also as a solid satellite. If we enlarge the nucleus to the size of a basketball, its electron satellite would proportionally be the size of a marble orbiting the ball at a seven-mile radius! So then, what is there actually between the basketball and the marble?
It is a void, or rather, a pure quantum vacuum.
Now then, to add further perspective with another analogy: if we wanted to accumulate all of the real matter within a single human body into a single solid block, we would have to compress all of our atoms with a powerful (& imaginary!) press to eliminate all the space, or vacuum, within them. Surprisingly, if we undertook this hypothetical compression, our total mass would hardly fill half of a thimble! As a result, I doubt that the marketplace would offer more than 7 dollars for the sum of our body’s organic compounds, even with an interested buyer.
So, to answer the question: Scientifically speaking, the human being is an enormous set of macromolecules organized into a complex system which, over time, generated cells which eventually specialized into greater and greater complexity. These specialized groups formed vital organs, such as the neurons in the brain, with the capacity to perform more and more complex tasks, such as cognitive function. Furthermore, after careful consideration of the micro-universe of the atom, we know that the internal structure of every macromolecule that belongs to our body is mostly empty of actual matter.
To sum it all up in a sentence: human beings are seemingly equivalent to an empty balloon, where waves of electrons and quarks vibrate vigorously, and which is perceived by the human mind as a solid object thanks only to the Cognitive Processor. (For more, reference the Terrestrial Cognitive System in the ‘Human Theorem’).
