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".

Will Humanity Be Trapped In The Solar System Forever? What Would Humanity Do Without Ftl And Wormholes?
The solar system is a system of celestial bodies kept in motion by the sun's gravity, which means that all bodies within the effective range of the sun's gravity are part of the solar system, so by this definition, how large is the solar system?

Scientists Discover 2 Billion Year Old Nuclear Reactor, Is It True That Earth's Civilization Is Constantly Reincarnating?
Prehistoric civilization have always been the talk of the town, and it's no wonder - after all, humans have been around for so short a time in the history of the planet that if we were to compress the history of the planet into a single day, then humans would probably only appear in the last two minutes of that day. In the past, there have been frequent claims of the discovery of suspected prehistoric civilization, the most notable of which would be a two-billion-year-old nuclear reactor.

The Speed Of Light Is Not The Speed Limit Of The Universe, It Is As Slow As a Snail Compared To These Speeds
The universe is so unimaginably large that even if humans were able to travel at infinitely close to the speed of light, they would not be able to penetrate its mysteries. Fortunately, the speed of light is not the speed limit of the universe, so it is entirely conceivable that in the distant future, humans may somehow be able to escape the shackles of the speed of light.

What Is The End Point Of The Evolution Of Carbon-Based Life? How Far Away Is Humanity From This Endpoint?
Theoretically, life can take many different forms, such as silicon-based life, sulphur-based life, carbon-based life, amino-life, hydrogen-based life, etc. However, so far we only know that life exists on earth, and all known life, including us humans, is carbon-based.

How Much Energy Is Released When 1 Kilogram Of u-235 Is Fissioned? How Long Will There Be Enough Uranium On The Planet For Human Use?
If mankind can master the method of extracting uranium from seawater in large quantities in the future, there will be enough uranium on the earth to last for tens of thousands of years, even hundreds of thousands of years!
