Geometrization of the universe is not the best way to understand it. It is ridiculous to consider a shovel as a pit with which it is dug. Mathematics is a tool for understanding the material world, but not the world itself.

Interesting reasoning, but how can time flow if it's not physically there? Time is just a tool with which we can judge the speed of processes in the material world.

Relativistic time dilation usually refers to the kinematic effect of the special theory of relativity, which consists in the fact that all physical processes in a moving body are slower than in a stationary body relative to a stationary (laboratory) frame of reference. Relativistic time dilation...

It follows from Special theory of relativity that as the speed of movement increases, three circumstances arise: the mass of the moving object increases, its size decreases in the direction of movement, and the passage of time on this object slows down (from the point of view of an external...

Planck units are one of the natural systems of units. How they are calculated can be viewed on the Internet.

In physics, the concepts of "length", "width" and "height" are used to characterize space. These concepts are numerical characteristics of the extent of objects, which, in fact, are the means of measuring this extent. Physically, length, width, and height do not exist. To measure the length, SI...

To characterize matter, the concept of "time" has a more abstract character than space. If we perceive space as a container of material objects and their ability to move mechanically, then by time we mean the change of events and the duration of the observed processes in space. Space can be...

The coordinate system is a tool for exploring space. Time is a tool for studying the duration of processes in space. Since processes can occur at different speeds in each system, the time in each system is different from the time in other systems.Coordinate and time systems do not physically...

I totally agree with that.

I write the word "invented" here with sarcasm. The word "composed" is more appropriate here. What was the reason for this is not so important.

Einstein invented photons, but do they exist in the real world? The proof of the existence of photons is considered to be the photoelectric effect, which can also be explained by the effect of an electromagnetic wave on a photocell. There are cases when the wrong model can give the right results.

"How can something that doesn't exist in nature be curved? Is it possible to curve units of measurement, such as the meter, kilogram, or second?"

First, of course, there will be a temporary base and flights from the Moon to Mars can already be planned. But the main focus should be on a long-term base on the Moon, not on Mars.

In my opinion, it is necessary to settle the moon first, and only then to make trips to Mars. In this case, flights to Mars will be both cheaper and safer. So far, Mars can be explored with the help of robots.

On average, using modern technology, a flight to Mars takes from 6 to 9 months. Astronauts will be exposed to significant amounts of cosmic radiation, which can increase their risk of developing cancer and other radiation-related diseases. Complete protection from cosmic radiation is...
