I was wondering how everything we know came together to be the way it is now and what will happen to us as a species.
The history of everything began 15 billion years ago.
The universe as we know it was created by a huge explosion of matter to create space-time. A dense and fiery universe began to inflate.
Over three billion years, optically dense matter/energy decoupled and created an invisible universe.
It took another billion years for clumps of matter to form. As the nuclei synthesized, they formed protogalaxies.
After more than 5 billion years after the Big Bang, galaxies were formed. Later, new galaxies arose, more similar to ours, with heavier nuclei.
Around the 10 billion year mark, our solar system formed, with planets in orbit.
A billion years later, in the earth’s primordial oceans, atoms combined to form macromolecules capable of self-reproducing and self-assembling. This was the DNA, the basis of all life.
DNA is the alphabet of life. Two strands of a double helix are joined by base pairs. There are four bases: adenine, guanine, thymine, and cytosine. All living organisms are made up of these four bases.
DNA resembles a spiral staircase and the order in which the bases are arranged in it creates a particular organism. This DNA assembles an organism around itself and copies itself. This copy is not always exact. In most cases, new mutations result in the demise of those organisms. In some cases, however, it increases the chances that the DNA will survive and become a biological adaptation.
About 3 million years ago, our first ancestors inhabited the earth. They became increasingly sophisticated. From the first hominid to 8000 BC. C. was the Old Stone Age; from 8,000 BC C. to 6,000 a. C. was the Stone Age, and from 6,000 a. C. to 3,000 a. C. was the New Stone Age. From 3,000 BC C. to 2,000 a. C. was the Bronze Age. And from 2000 BC to the time the Christian calendar begins was the Iron Age.
The last millennium spanned from the Middle Ages to the Modern Age. The most critical stages occurred after the fall of the Roman Empire, the Middle Ages; the pestilence that spread from Asia to Africa, the Black Death; and the two world wars, which has given rise to the new threat of nuclear proliferation.
Where will we go now?
The next 100 years will be the most critical. It is at this stage where the pressure of the new changes will be imposed on us. In addition to the obvious political and economic problems, there are new problems that threaten our survival as a species: nuclear proliferation, environmental disasters, population explosion, epidemics and famines.
One solution may be the creation of a world government because the problems will be too much for any one nation. Assuming that by sharing resources, peace and stability are established, and most of our critical problems are resolved, there will still be an evolutionary drive pushing us to build civilizations under the sea and move into space.
The reason for this is that the world population will be around 36 billion people by the end of the century if it continues at the current rate of 1.9 percent, which means that it doubles every 40 years.
This will result in the creation of a new species of human beings to deal with the construction and inhabit the new environments. Failure to do this will mean that by the year 2600, people will be shoulder to shoulder and the earth will be literally red hot from electrical consumption.
In the last 10,000 years, there have been no significant changes in human DNA, but everything may change dramatically in the next 1,000 years as genetic engineering works to create improved human beings. It will probably start with plants and animals, with many restrictions against using them on humans, but someone will break the taboo and start creating humans outside the womb. These humans will not be restricted by the size of the birth canal and will develop larger brains. Our current brains weigh 3 pounds. Future brains can weigh around 5 pounds. They will probably also be bigger and stronger than we are now.
In general, the whole drive of everything, from our perspective, has been the evolution of matter from nothing, then life forms from seemingly random permutations, and then the evolution of a particular species until it took over everything. the planet.
It is an amazing story.
Of course, many links are missing.
What happened before the Big Bang? What hit? How were the atoms necessary for life arranged to create the macromolecule that defined all life? How did a creature create a brain and higher nervous system?
One thing is certain: the future will not be like the past. The prevailing wisdom that there is nothing new under the sun is shocked.
