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
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?
There Is No Air In Space To Provide Reaction Forces, So Where Does The Power To Move The Spacecraft Forward Come From?
The law of conservation of momentum means that the total momentum of a system remains constant when it is not subject to external forces or when the sum of the vectors of external forces is zero
Once The World's Largest 'Eye In The Sky', It Sent Telegrams To Aliens, Now It's a Dumping Ground
The Arecibo Radio Telescope in the United States used to be the largest radio telescope in the world, with a diameter of 350 meters. As the most powerful radio telescope ever built, scientists have achieved many scientific results with the radio Arecibo radio telescope in the past decades
Schrödinger's Cat Is Only One Of The "Four Great Beasts" Of Physics.
The "four great beasts" of physics actually exist only in thought experiments, and their proposal helps to develop and improve the relevant theories
If The Milky Way Were Reduced To The Size Of An Electron, How Big Would The Universe Be?
Scientists using modern observation equipment have determined the size, position, distance and other data of most of the objects in our galaxy
Why Is The Singularity Of a Black Hole Infinitely Small In Size And Infinitely Dense? Scientists: We'Re Helpless Too
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
Japanese Scientists Have Stored 50,000 Tonnes Of Ultra-Pure Water Underground.
Although ultra-pure water does not exist in nature, humans can prepare it themselves
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.
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"
