How much do we know about Nature?

MEXICO CITY (apro).-The physics we know seems admirably powerful. We have come to understand many phenomena. Einstein showed us that space-time curves and made us see results that at first were practically paradoxes for everyone. The quantum mechanics model, for example, which I believe follows the Copenhagen interpretation, seems to be quite adequate and is capable of predicting an endless number of events. Perhaps it is the most elaborate theory of the human being.

And if I talk about this, it is because in light of the article on the quantization of time, a new reflection arises that I now share. If it is true that the Planck time, which is 5.39106 x10^-44 seconds, and this is, according to Wikipedia: “represents the time it takes for a photon traveling at the speed of light to travel a distance equal to the Planck length. We can therefore think that time is quantized and moves in intervals of 5.39 x 10^-44 seconds. Beyond that, time has no meaning and neither does talking about physical phenomena.

But what interests me is the persistence of the laws of physics. Get into the shower and turn on the tap… How long does it take for the water to realize that it is in the presence of a gravitational field (which makes the water fall downward)? Because there must be an interaction between the gravitational field and the water, right? Come on, we are not talking about an instantaneous interaction. They are two components of a system that interact with each other and therefore, a certain time must pass for the gravitational field to exert its action on the water.

Of course, by the time of human beings, water “instantly” becomes aware of the Earth’s gravitational field and it seems natural to us that water falls, but what about that interaction? How does it arise? How do you realize each other? Does it occur in minimum Planck time or does it take n number of Planck time units, chronons, for the field to take the corresponding action. How many chronons are required for the interaction to occur?

It seems to me that the physics that we know is not even contemplated. For example, we understand the mechanisms and we human beings have created laws that model this universe in which we have to live, which has apparently immovable rules and, furthermore, which persist in their actions no matter what happens.

The question, which many others have already asked before me, is: What would the Universe be like if the laws were different? For example, we know that the Law of Universal Gravitation, in the denominator, r^2, that is a two. It is not 1.99999 or 2.00000001, to say the least, it is a dry, accurate 2. Because? And I go further, Are we on the right path to making a model of this universe in which we live? because… how can it be that the interaction of fields with other components requires so many mathematical tools to model it? Are we doing something wrong? Or perhaps our mathematics is too rudimentary to explain things?

For the moment at least, I believe that physics only describes the Universe, but in reality, we are far from being able to explain why this is the case.
