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
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
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.
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.
Life May Not Have Originated On Earth, And There Is Growing Evidence That Life Should Have Originated In Outer Space
In the past days, scientists have been working on the study of meteorites, and as the research continues, there is more and more evidence that life should originate from outer space
There Have Been Ways To Create Artificial Gravity For a Long Time, So Why Isn't Artificial Gravity Used On Space Stations?
If we make the space station in space into a ring and let it rotate, then the humans in it will also feel the "centrifugal force" to "push" themselves towards the outer wall of the space station
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?
If Scientists Have Discovered Something That Shouldn't Have Existed Hundreds Of Millions Of Years Ago, Should Humanity Be Wary?
In theory, when a civilization develops into a civilization that can cross the stars, there is basically no risk of extinction
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
The Speed Of Light Is Not The Speed Limit Of The Universe, It Is As Slow As a Snail Compared To These Speeds
The universe is so unimaginably large that even if humans were able to travel at infinitely close to the speed of light, they would not be able to penetrate its mysteries. Fortunately, the speed of light is not the speed limit of the universe, so it is entirely conceivable that in the distant future, humans may somehow be able to escape the shackles of the speed of light.
