In theory, when a civilization develops into a civilization that can cross the stars, there is basically no risk of extinction

Earthquakes are a natural phenomenon known to all of us, and they are not unique to the earth. In theory, any planet with a solid crust can have an 'earthquake', and for the sake of distinction, we can call it a 'starquake'. The strength of a 'starshock' varies from planet to planet, so how terrible is the strongest known 'starshock'?

Although ultra-pure water does not exist in nature, humans can prepare it themselves

A rigorous discussion of the unknown is not possible, so it is necessary to narrow down the universe we are discussing to only the universe we can see

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?

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

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.

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

In the evolutionary history of human beings, the gradual increase in brain volume is an important marker

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