What are relation between unique describe of world and covariant law?

This means that different observers in different frames of reference will perceive the same events differently. However, both theories also hold that the laws of physics are the same for all observers, regardless of their frame of reference.So, in summary, the idea of a unique description of the world is dependent on the observer's frame of reference, but the laws of physics remain constant for all observers.

If we consider have an unique external world therefor all people who want to describe this, should portray one thing.

it seems logically that all people with different situation, either they are stationary or they move with constant speed or variable speed, describe world uniquely.

this condition leads to the laws of physics to be the same in all different coordinate system - in General relativity, we see this but in Classical mechanics, its true only for inertial coordinate system -

here arises a question, what are relation between unique describe of world and covariant law

Hi sadegh4137,

I think you've answered your own question: it depends on your point of view (your frame of reference).

Both theories of relativity up-end the ideas of simultaneity and absolute motion.
 

What is the unique description of the world?

The unique description of the world refers to the specific characteristics and properties that make up our universe and everything within it. This includes physical laws, fundamental forces, and the behavior of matter and energy.

What is a covariant law?

A covariant law is a physical law that remains the same regardless of the chosen reference frame or coordinate system. In other words, the mathematical form of the law does not change when a different set of coordinates is used to describe the system.

How are the unique description of the world and covariant laws related?

The unique description of the world encompasses all of the fundamental principles and laws that govern the behavior of our universe. Covariant laws are a subset of these principles, and they play a crucial role in our understanding of how the world works.

Why are covariant laws important in science?

Covariant laws are important because they provide a consistent and universal framework for describing and predicting physical phenomena. They allow scientists to make accurate and reliable predictions about the behavior of the world and to develop new theories and models based on these laws.

Can unique descriptions of the world change over time?

Yes, our understanding of the unique description of the world is constantly evolving as we make new discoveries and advancements in science. As we gain a deeper understanding of the fundamental laws and principles that govern the universe, our unique description of the world may change and improve over time.
