Scientists predicted the existence of dark energy, more mysterious than dark matter, does it really exist?
科学家们预测暗能量的存在

The undeniable point is that, although humans currently detect the universe, about 93 billion light years in diameter range, however, in fact, scientists generally believe that this is just the tip of the iceberg.
In the vast universe, in addition to the bright matter visible to our naked eye, let's say hundreds of billions of galaxies, more stars, planets, etc., and even human detection equipment can see a variety of radiation energy, in fact, they all belong to the bright matter, and they account for only 5% of the total mass and total energy in the universe.
Some of you may wonder, what is the remaining 95%? The answer is dark matter and dark energy, which account for 27% and 68% respectively. Thus, it can be seen that the most important component of the universe is the dark energy, but what is dark energy?
What exactly is dark energy?
Although scientists have confirmed the existence of dark matter through galactic rotation and gravitational lensing as early as decades ago, the study of dark energy is only in the last few years.
Because dark energy is in fact more mysterious than dark matter, it was only at the beginning of the 21st century that human beings began to suspect its existence, but it is extremely difficult to detect it.
What is dark energy? According to the official explanation, it is a key energy that can drive the movement of the universe. Like dark matter, dark energy is also invisible, untouchable and cannot be directly observed, and dark energy is also unable to reflect and absorb, radiation and other types of light and energy in the universe, which makes it more difficult for humans to find it.
So, since dark energy human existing science and technology is unable to find it, scientists and how to confirm that dark energy must exist? This begins with the discovery of the expansion of the universe by American scientists in 1998.
According to the records at that time, American scientists in the process of studying supernovae, accidentally found that the universe is expanding at a super speed, which is contrary to the existing physical theory, which means that in the universe, there is a mysterious force that humans do not know, manipulating the movement of the universe.
This mysterious force is dark energy. Interestingly, as early as in Einstein's general theory of relativity, Einstein had found that there may be "dark energy" in the universe, but Einstein eventually thought his discovery was wrong, that the universe is static and stable, so, Einstein did not make predictions about dark energy.
Then, in 1929, when the expansion of the universe was discovered, Einstein himself was regretful, after all, more than 10 years ago, in fact, Einstein had already discovered this problem, but finally chose the wrong answer.
Dark energy is related to the origin and fate of the universe?
There is a view that dark energy determines the origin, evolution and fate of the universe, because dark energy is the main body of the universe, it is everywhere and extremely evenly distributed, and it can even be said that there is dark energy around us, only that we cannot find it.
That said, after more than 20 years of research on dark energy, scientists are still unable to say exactly what it is, but what is certain is that since the Big Bang, dark energy has been generating a force that pushes outward, thus leaving the universe in a constant expansion.
In addition, when the universe eventually expands to a certain limit under the manipulation of dark energy, this time, the dark energy will tear all the matter in the universe, so that the universe towards the end of life.
Researchers say that dark energy may have phantom energy, it will accompany the continuous expansion of the universe, thus increasing its own density, so that they become larger and larger, so that all the galaxies in the universe are stripped, resulting in the universe can no longer form a stable situation, and eventually, the universe will be scattered and open.
At the same time, there are researchers believe that perhaps humans have been looking for answers to the dark energy, may not exist in itself, they are "small black holes" in the universe, for example, in some studies have mentioned that if one day in the future, the universe is no longer new stars are born, while all the stars have become black holes or If there are no new stars born in the universe, and all stars become black holes or black dwarfs, then the whole universe will be in darkness.
This time the universe, also towards the end of the fate, but, because the proportion of dark energy universe is too large, which also makes this idea, is not recognized.
In addition, there are views that dark energy may be related to the multi-dimensional universe, under its role, leading to the emergence of the universe of multi-dimensional space, while dominating the universe step by step towards destruction, and eventually after the destruction of the universe, re-accumulation of energy, to create a new universe out, this, what do you think? Do you think dark energy exists?
