We live in the end of the universe

The universe today is not the same as yesterday. At each passing moment, there are some very small but important changes that are already happening, even when we are not aware.

The universe is expanding, the distance between cosmic structures is increasing over time. In the end, the universe will "die " in the cold. Unfortunately, nothing can change this fate.

A second ago, the universe was a little smaller, a second from the moment you read this line, the universe was a little bigger. These subtle changes all appear at the macroscopic levels that, compared to them, humans are atoms, no way to be aware.

As the universe expanded, the radiation, matter, neutrino, temperature and dark energy inside the universe all changed. What we observe in the sky will also change dramatically.

The periods of the universe

There are six different periods in the development of the universe since the Big Bang. Unfortunately, we are living in the last age.

The scientific world divides the life cycle of the universe into periods by the universe constantly expanding.

The chart below shows that everything that exists in the universe has a certain amount of energy in it: matter, radiation, dark energy . When the universe expands, the mass that these forms of energy occupy change, each type will have different development density.

Material (top row), energy and radiation (middle) and dark energy (bottom) manifest differently in cosmic periods.While the density of matter and radiation are reduced, dark matter and dark energy remain unchanged.(Photo: Forbes).

The more existent the universe will expand. In the future, the cosmic temperature will decrease, instead of the past that was very hot. Star dust, hot gas, and very chaotic matter will become local clusters like the Solar System, the galaxy. Also, of course the universe will be much bigger in the future.

By applying known laws of physics, comparing possible solutions to obtained observations and measurements, humankind can determine our origin and destination in the vast universe. Green boat is Earth.

It is possible to extrapolate our past history from the beginning of the Big Bang and even before that, until the period of the universe was constantly expanding. We can also extrapolate the current universe to foresee the last fate awaiting in the distant future.

Theoretically, the development of the universe could be understood by Einstein's theory of relativity, when the laws of spacetime were proved.In the future, we will still get far away light from galaxies in the past, but the speed of light will limit us to the visible distance of 14 billion light-years, the age of Space.Beyond that distance, light will never touch us, because we are drifting faster than the speed of light.(Photo: Forbes).

When dividing the period based on the characteristics of the universe, there are six different ages that the universe will experience.

1. The pre-expansion era : Big Bang has not yet appeared.
2. Primitive era : At the beginning of Big Bang until the last nuclear interactions occurred in the early universe.
3. Plasma era: The end of nuclear interaction and non-scattering particles, until the universe cools enough to form neutral particles.
4. The Dark Age: Since the formation of neutral matter until the stars, the first galaxy re-ionized (ionizing neutral particles into neutral particles) of the universe's intergalactic space.
5. The age of the stars : At the end of the re-ionization process until the formation and growth of large-scale structures cease, the density of dark energy dominates over the density of matter.
6. The era of dark energy : The final stage of our universe, as expansion expands and objects are disconnected. We will go further into the dark space.

After the Sun becomes a black dwarf, if nothing pushes or collides with the Earth's remnants, the gravitational radiation will eventually cause us to spiral and be swallowed by the Sun's remnants.(Photo: Forbes).

In short, humans have entered the final era for the beginning of billions of years ago. Most important events that define our cosmic history have happened.

The end of the universe

And then, with only black dwarfs, so massive, isolated masses of matter that nuclear fusion itself takes place within them, galaxies become sparse and disconnected. together in the empty universe, constantly expanding.

These "corpses" in this final state will survive many years later and be pushed apart, because dark energy is still the dominant factor in our universe.

Dark energy has accelerated the expansion at 6 billion years ago and began to dominate the universe around the time our Solar System and Sun were born.

The universe may have six stages but the entire history of the unfortunate Earth has been in the final stages. Look at the universe around, try to admire the beauty of the leftover because it will certainly not be so colorful and full of 'life' like this anymore.
