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

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

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.

In the macroscopic world, the solar system is a system of celestial bodies centred on the sun, in which the vast majority of mass is concentrated and the major planets orbit the sun, while in the microscopic world, an atom is a microscopic system centred on the nucleus of an atom, in which the vast majority of mass is concentrated and electrons orbit the nucleus.

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

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 Much Energy Is Released When 1 Kilogram Of u-235 Is Fissioned? How Long Will There Be Enough Uranium On The Planet For Human Use?
If mankind can master the method of extracting uranium from seawater in large quantities in the future, there will be enough uranium on the earth to last for tens of thousands of years, even hundreds of thousands of years!
