Maybe you have a lot of friends, or an important job, or a really big car. But it might humble you to know that all of those things – your friends, your office, your really big car, you yourself, and even everything in this incredible, vast Universe – are almost entirely, 99.9999999 percent empty space.
Every human on planet Earth is made up of millions and millions of atoms which all are 99% empty space. If you were to remove all of the empty space contained in every atom in every person on planet earth and compress us all together, then the overall volume of our particles would be smaller than a sugar cube.
Yes, indeed nearly everything is empty space including space between the electrons of an atom to its nucleus. 99.9999999% of Your Body Is Empty Space .
99.9999999% of your body is empty space.
But it is an important mystery. It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe.
There's a limit to how much of the universe we can see. The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us.
Physicists tell us that there is no such thing as empty space. Imagine that you have removed every atom from a small box to try to make a perfect vacuum inside. That would be difficult but not impossible.
The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster.
In life, the human body comprises matter and energy. That energy is both electrical (impulses and signals) and chemical (reactions).
Again, atoms never touch in the everyday sense of the word for the simple reason that they don't have hard boundaries.
The human body is approximately 99% comprised of just six elements: Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. Another five elements make up about 0.85% of the remaining mass: sulfur, potassium, sodium, chlorine, and magnesium.
Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium.
You've probably heard that the human body is made up of over 70 percent water, and that drinking enough every day is essential for everything from maintaining a healthy weight to energy levels and flushing toxins out of the body.
The cells contain water molecules and various biomolecules viz. proteins, lipids, carbohydrates, nucleic acids, etc. The molecules present in the cell are made up of basic elements such as carbon, oxygen, hydrogen, and nitrogen. These elements possess energy; hence we can say that humans are made of energy.
An atom a fundamental piece of matter. (Matter is anything that can be touched physically.) Everything in the universe (except energy) is made of matter, and, so, everything in the universe is made of atoms.
The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
While the total energy of a system is always conserved, the kinetic energy carried by the moving objects is not always conserved. In an inelastic collision, energy is lost to the environment, transferred into other forms such as heat.
Part of Hall of the Universe. Every atom of oxygen in our lungs, of carbon in our muscles, of calcium in our bones, of iron in our blood - was created inside a star before Earth was born. Hydrogen and helium, the lightest elements were produced in the Big Bang.
Our bodies actually do contain atoms that were forged in stars. In fact, most of the elements that we are familiar with, we don't know how to create them originally other than in stars. So, it's not us here and the universe out there. We are all part of the same wonderful physical entity.
In fact, recent estimates put dark matter as five times more common than regular matter in our universe. But because dark matter does not interact electromagnetically, we can't touch it, see it, or manipulate it using conventional means.
In about 100 trillion years, the last light will go out. The bad news is that the universe is going to die a slow, aching, miserable death. The good news is that we won't be around to see it.
One theory suggests the existence of a “Hidden Valley”, a parallel world made of dark matter having very little in common with matter we know.
Our Galaxy Is Also Surrounded By A Void
Not only is the inside of the Milky Way home to a big void, but chances are we're also surrounded by one. This is known as a Local Void, and likely surrounds the outside of the Milky Way galaxy. However, our galaxy tends to move towards areas with more density.
99.9999999% of Your Body Is Empty Space.
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.
