Are You Alone In The Universe - proofs, facts, and necessity

Are you alone in the universe Or, are you connected to something?

First of all, you are part of a group of mammals, still very young. But we can make blog-posts already and build big hadron colliders. We also split the atom and invented the Pokémon. We come from an ancient life form, which started living about three and a half years ago a billion years ago. We feel like we are under the control of this planet, but we really aren't. A small asteroid or a creative virus is really all it would take to kill us for good. credits humanity with the power to destroy the planet, but even with all of our nuclear toys, we'd probably just cause a huge mass extinction at best. we could kill 90% of everything living on this planet.

 Big deal! after a few million years , life would be back everywhere. Most microscopic life and life below the surface would not even be bothered that much doubt. On a geological time scale, our impact on Earth is a kind of laughable. We are actually not that powerful. We live on this small wet rock that accelerates through space, following a huge ball of burning plasma. One day, this plasma ball will stop burning and, most likely, kill us in the process. If we survived the death of the Sun, and colonized a galaxy, Theoretically, we could survive until the last star in the Universe goes out. After that, life becomes quite impossible. Okay, so it all ends.

Where does that leave you as an individual?

 At one point in your life, for about half an hour, you were the only single cell in your mother's womb. A creature only 0.1 millimeters in diameter. Today, you make up about 5,000,000,000,000,000 cells. Fifty billion incredibly complex little biological machines, which are much larger and more complex than the average bacteria. They work by the laws of physics and chemistry, and use micro-machines to build proteins, make usable energy, devour food, transport resources, transmit information, or reproduce. They communicate, duplicate, commit suicide, fight intruders, and perform super-specialized functions for the greater good of keeping you alive .. yes, you can have babies. But, we are the “you” part in this area, if you are made up of billions of little things? The basic information for "you" is stored in DNA.

 A molecule that codes for the genetic instructions used in the development and functioning of all known living things. If you were to untangle it would be two feet long. If you combined all of the small DNA chains in all of your cells, you would get a chain so long that it would extend to Pluto and the Earth. It's quite long. And your DNA is a direct connection to your very first ancestor. Take a second to think. In every cell of your body, there is a small chain of things that has been there in various forms for 3.4 billion years. It has evolved, it has mutated, it reproduces, billions of times, but it connects you directly to the first living being on this planet. We could say that you have touched all living things that came before you, with your DNA.

You are more than your DNA:

The body is made up of seven octillion atoms. It's seven billion, billion, billions. About 93% of the mass of the human body is made up of just three elements. Oxygen, carbon and hydrogen. Oxygen and hydrogen are mainly found in water, which represents about 60% of the body by weight. Carbon is perhaps the most important element for life. It can easily bond with other atoms, allowing the construction of long chains of complex molecules, which constitute the solid part of "you". The remaining 7% is a round of the periodic table of the elements. Nitrogen, calcium, phosphorus, potassium, sulfur, sodium, chlorine, magnesium, iron, fluorine, zinc, copper, iodine, selenium, chromium, manganese, molybdenum, cobalt, lithium, strontium, aluminum, silicon, lead, vanadium, arsenic and bromine.

Uh! By the way, it also means that you are about 0.5% metal. No matter what your favorite music is. Anyway, these elements perform various functions, such as: allow the transport of oxygen, which strenghthenes bones and cell structures, carry signals, drive chemical reactions, and much more. Your body is in a constant state of transition. Every sixteen days, 75% of "you" has been replaced, because in this period of time a healthy human exchanges about 100% of their water . Each year about 98% of your atoms are replaced by new ones, and every 5 years near all the atoms that make up your body weren't there five years ago. So you could call yourself a temporary collection of atoms.

But where do these atoms come from?

At the beginning of the Universe, there were mostly hydrogen and helium atoms. Huge gas clouds formed, over the millennia, and grew, denser and denser, until they collapse under their own gravity, giving birth to the first stars. In the nuclei of these stars hydrogen has been converted to helium under extreme conditions. After millions of years, the hydrogen became depleted, and the stars began to die. In super-extreme conditions, everything we know today was created a fraction of a second before dying and exploded in supernovas. They pulled most of their content into space, while the nuclei collapsed and became black holes.

All of these have traveled through space for who knows how long, until they get to a different cloud, which is slowly forming a new star, our Sun These elements, which were once inside a star, the planets formed, and found their way to Earth, where they allowed life to begin. So, we are directly connected to the first stars born in the Universe. We are part of the Universe. The idea of ​​being a tiny, deeply linked part of a huge structure is truly mind blowing. We don't know what it all means. Or, if it means something. We know that we are made of small parts that connect us to everything in the Universe. For the start of everything. And it's kind of a nice thought: You're not alone. You never have been. You'll never be.
