A Probe That Flew 22.8 Billion Kilometres And Finally Sent Back Pictures That Teach Mankind a Vivid Lesson
Although the Earth is just a "grain of dust suspended in the sun" in the universe, for us humans, this "grain of dust" is irreplaceable.

Will Jupiter, The 'King Of The Planets' In Our Solar System, Become a Star In The Future?
After the sun evolves into a red giant, the hydrogen in its core is almost completely fused into helium, so the nuclear fusion inside the sun stops, after which the sun loses its internal radiation pressure and continues to collapse, leading to a constant increase in temperature and pressure in its core, while the helium in the central region of the sun is gradually compressed into the condensed state.

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.

It Turns Out That We Often 'Travel' Through Time, But We Don't Realise It, So How Does This Happen?
It has long been discovered in practice that the phenomenon of "gravitational time dilation" does exist

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".

Earth Not Safe Anymore? Scientists Reveal Four Evil Alien Civilizations: Capable Of Invading Earth
For humans, the universe is too dimensional for us to see the details of its depths for the time being

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

Nuclear Fusion Ends At Iron, So Where Do Elements Heavier Than Iron In The Universe Come From?
The energy released by nuclear fusion is actually an important basis for stars to be able to maintain their stability

Does a Planet With a Diameter Of 1 Light Year Exist In The Universe?
The mass of a star cannot grow indefinitely, it can only reach the "Eddington limit" at most, so beyond this threshold, it will soon "eject" the extra material

There Have Been Ways To Create Artificial Gravity For a Long Time, So Why Isn't Artificial Gravity Used On Space Stations?
If we make the space station in space into a ring and let it rotate, then the humans in it will also feel the "centrifugal force" to "push" themselves towards the outer wall of the space station
