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

What Exists In The Vast Space Between The Nucleus And The Electron? Is It An Absolute Vacuum?
In 2013, CERN discovered the existence of the Higgs boson for the first time.

If You Sink a 100kg Solid Iron Ball Into The Deepest Part Of The Sea, Will The Ball Be Deformed By The Pressure?
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?

How Fast Is Mach 1? How Many Kilometres Per Hour Is It Equivalent To?
In essence, sound is actually a wave generated by the vibration of the object, the sound waves in the air is actually a "longitudinal wave"

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?

Why Is It That Only Uranium And Plutonium Can Be Used For Nuclear Fuel? But Not Other Elements?
The more "nucleons" an atomic nucleus contains, the greater its mass, but scientists have found that the average mass of the "nucleons" of different elements is different

How Terrible Is The Strongest Known 'Starquake'? It's The Equivalent Of a 21 Magnitude Earthquake And Would Be Too Much For Earth To Handle
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'?

The Earth Has Mountains Over 8,000 Metres High And Ocean Trenches Over 10,000 Metres Deep, So Why Do Scientists Still Say The Earth Is Round
There is a view that the reason why the Earth looks round is because of the role of the Earth's oceans, which simply means that a large amount of seawater has "filled in" the undulations of the Earth's surface.

If The Earth Shrank To The Size Of An Electron, How Big Would The Universe Be?
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

Exploring The Limits Of Physics, What Is The Smallest Matter In The Universe?
Everything we can see in the universe has an internal structure and they are all made up of smaller matter, so what is the smallest matter in the universe?
