During the previous period, the topic of mysterious radiation in the universe had given rise to a new amount of debate in the scientific community. It is said that scientists have made new discoveries and interpretations of some cosmic radiation, which is curious to know how many secrets are hidden in the universe that we do not know? Do those mysterious radiations have the truth to subvert our knowledge
Gamma-ray storms are not just a distant "passenger."
Gamma-ray storms, which are a cosmic radiation from 1. 9 billion years ago, have strong, short-lived, high-energy properties. You might have thought it was an occasional break-in in the universe, and then it didn't have much to do with earth. It's a vast boundary across the universe, penetrating galaxies, planets, and finally reaching our planet. The radiation's got a lot of power
It is worth noting that, since ancient times, gamma-ray storms have been a mystery to scientists. Who started this devastating event? This is really challenging human wisdom and courage. Can we just watch this puzzle continue to exist? Definitely not. Scientists are still trying to find out. So gamma-ray storms are not the kind of distant existence that has nothing to do with us, and their origins may be revealed one day, bringing us a new cognitive shock。
To sum up, while distant and mysterious, the gamma-raystorm's “visitation” to the earth and the mystery of its unsolved origins suggest that it is by no means a simple “passenger” that we can ignore and that one day, perhaps, will make a big difference in our understanding of the universe because of new discoveries. But don't underestimate the fact that the universe seems to be a long way off
The cosmic microwave background radiation is not an ordinary noise
Judicial examination (which has been transformed into a legal professional qualification examination) and change in eligibility to apply
Cosmic microwave background radiation (cmb), which is one of the most powerful evidence of big bang theory, is considered to be the “sound back” of the early universe. When arnold penzias and robert wilson were working at bell's laboratory, they were trying to test a new microwave receiver to receive radio signals outside the galaxy, and they encountered a constant noise. They initially thought it was equipment failure and even checked for external disturbances such as bird dung inside the antenna. It's a very difficult process
More crucially, they realized that they had unwittingly captured background microwave signals in the universe. It's not just "noise," but it comes from about 380,000 years after the big bang, when the universe just cooled to a state that allowed the photon to spread freely. This means that we can see something about the birth of the universe through this seemingly insensitive noise. Isn't that amazing? It would have been a shame if they had handled the noise so easily
So, the cosmic microwave background radiation must not be ignored as a common disturbance, but it is of great significance and provides us with very valuable clues about the birth of the universe. Sometimes those little noises that we see as trouble may be the key to opening the mystery of the universe
Hawking's radiation theory is more than just a black hole
Everyone knows hawking's well-known radiation theory, which was meant to mean that with the destruction of the surrounding quantum field in the event landscape (the outermost boundary of the black hole), black holes evaporate over time and gradually lose mass in a strange form of radiation. But now, new research shows that the event scene is not essential to the process. Astrophysicists at the university of radbé, the netherlands, found that the same could be done with sufficiently steep slopes in space and time。
What does that mean? That means that hawking's radiation theory doesn't apply only to black holes. All large objects, even the universe, can evaporate. That's a reversal of what we knew before. We thought only black holes could evaporate through radiation. Did we have a narrow understanding of this change in objects in the universe? Obviously. Now it seems that many objects in the universe may have similar “fate”. The mystery of the universe is so deep
In short, the scope of the hawking radiation theory has expanded, giving us a new perspective on the evolution of objects in the universe. Don't think that our well-known theories can only be confined to their original limits
The truths about the mysterious radiation of the universe really refresh our knowledge. On the one hand, we have seen the complexity and mystical nature of the radiation in the universe, which has a variety of unexpected characteristics and effects; on the other hand, we have seen how valuable the spirit of scientists are in their constant search. In the future, will there be a new universe of radiation? Let's guess。
We live in this vast universe, and although knowledge of the universe is only the tip of the iceberg, every breakthrough in exploring the mysterious radiation of the universe, among others, brings us closer to the truth of the universe. I hope we keep this passion for curiosity and exploration of the universe。
