When Humans Reach The Second Level Of Civilization In The Universe, Will They Necessarily Build a "Dyson Sphere"?
If someone asks the question, are humans alone in the universe? I believe that most people would answer in the negative. In fact, the scientific community also generally agrees that there are a large number of intelligent civilisations in the vast universe, some of which may even be far ahead of our civilisation, and in order to better describe the technological level of intelligent civilisations in the universe, scientists have also proposed the concept of "Cosmic civilisation levels".

Why Have No Advanced Civilizations Visited Earth? Perhaps In Their Eyes, Humans Are Just Ants
Intelligent life is rare in the universe, or perhaps it is just wishful thinking on our part. As mentioned earlier, just in the galaxy, there are hundreds of millions of planets that have the natural conditions to nurture life, so a reasonable speculation is that life has evolved on many planets, and even a number of planets have evolved intelligent life.

Why Is It That The Discovery Of Extraterrestrial Life In Our Solar System Would Be The Beginning Of Despair For Humanity?
How exactly did such a complex life emerge on Earth? This is a great mystery to modern humans, but we are almost certain that the "birth of life" is a process that has a very small probability of occurring.

Mysterious Circles Have Appeared In The Universe And Scientists Don't Know How To Explain It... Is It The Emergence Of An Advanced Civilisation?
Whichever way you look at it, humans cannot be the only intelligent creatures in the universe. As far as we know, the universe has existed for at least tens of billions of years, so a reasonable speculation is that there is probably an advanced civilization in the universe that is hundreds of millions or even billions of years ahead of humans, and if that is the case, their level of technology is something that we humans simply cannot imagine.

There Is a Mysterious Force That Controls The Workings Of The Universe And About Which Mankind Knows Almost Nothing
Further research shows that this mysterious force accounts for 68.3% of the total mass energy of the universe, and it is because of this that it is able to overcome gravity and become the dominant force controlling the operation of the universe

If Scientists Have Discovered Something That Shouldn't Have Existed Hundreds Of Millions Of Years Ago, Should Humanity Be Wary?
In theory, when a civilization develops into a civilization that can cross the stars, there is basically no risk of extinction
