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
What Is The End Point Of The Evolution Of Carbon-Based Life? How Far Away Is Humanity From This Endpoint?
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.
Five Signs That Mankind Is Witnessing Its Own Evolution, As It Never Stops
In the evolutionary history of human beings, the gradual increase in brain volume is an important marker
Planet That Collided With Earth 4.5 Billion Years Ago Found? Scientists: It Could Be Inside The Earth
Earthquakes are a common natural phenomenon. On average, millions of earthquakes occur on Earth every year, except that most of them are so mild that they are largely imperceptible to humans.
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'?
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"
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
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.
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
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?
