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.

In 2013, CERN discovered the existence of the Higgs boson for the first time.

According to known exploration data, the deepest seabed on earth is the marianas trench, located at the bottom of the pacific ocean. The measurement data shows that the deepest part of the marianas trench can reach 11,034 meters, where the pressure is about 110 mpa, equivalent to 1.1 tons of weight per square centimeter. So the question arises, if you take a 100kg solid iron ball and sink it into the deepest part of the sea floor, will the iron ball be deformed by the pressure?

Since gravity is actually a manifestation of gravity, and the magnitude of gravity is proportional to mass, for those objects with smaller masses, their own gravity is smaller

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?

The reason we don't see time travelers is actually because they are not in our timeline

The "four great beasts" of physics actually exist only in thought experiments, and their proposal helps to develop and improve the relevant theories

NASA's Jet Propulsion Laboratory's Near Earth Object Research Center has such a database, which is called the "Fireball Database."

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!

In a good night sky, we can always see a sky full of stars and it seems to us that the whole universe is in full view. In fact, the stars we see in the night sky are only a tiny part of the milky way galaxy, which is just one of the trillions of galaxies that exist in the observable universe.
