A theoretical introduction to the theory of quantum gravity, the basic principles of quantum mechani

The theory of quantum gravity is a physical theory in which quanta is the discontinuous motion of particles of matter, and all quantum puzzles originate from this discontinuous motion. The combination of quantum theory and gravity, the theory of quantum gravity, is still in the research stage.

Quantum gravity, also known as quantum gravity, is a theory that describes the quantization of the gravitational field, which belongs to the corner of the theory of everything. It mainly attempts to combine general relativity and quantum mechanics as an unsolved problem in current physics.

In 1985, Penrose and Lindler published Spinors and Space-Time, which basically laid the foundation for classical relativity. Wald, on the other hand, developed an axiomatic quantum scum field theory in curved space-time. He started making semi-classical and semi-quantum things.

Wald's mathematics is good, and he does curved space-time quantum field theory, which is to use C star algebra and functional analysis. Wald's theory of curved space-time quantum fields clearly tells people that the algebra of the son of the Son is very important.

Quantum algebra is absolute, while particles, of course, are relative to the observer.

The basic principles of quantum mechanics are as follows:

1. Wave-particle duality:

One of the most fundamental concepts in quantum mechanics is wave-particle duality. In classical physics, matter is considered to be composed of particles, whereas in quantum mechanics, matter can exhibit both particle and wave properties. This means that matter can both exist like particles and travel like waves.

2. Uncertainty principle:

The uncertainty principle is one of the most well-known principles in quantum mechanics. It describes that when measuring the position and momentum of a particle, we cannot know the exact value of both quantities at the same time, because measuring the position interferes with the momentum of the particle, and measuring momentum interferes with the position of the particle, and this principle shows that in quantum mechanics, we cannot accurately ** the trajectory of the particle's motion.

3. Operators and eigenvalues:

In quantum mechanics, physical quantities are represented as operators. The operator acts on the wave function to obtain a numeric value, which is called the eigenvalue, which describes the value of the physical quantity, and the operator describes how to measure the physical quantity, this concept is very important in quantum mechanics, because it allows us to determine the value of the physical quantity by measuring the eigenvalue.

4. Entanglement:

Entanglement is a very peculiar phenomenon in quantum mechanics. It describes a system of blind bonds between two or more particles, the relationship between these particles occurs no matter how far they are from each other, and when two particles are entangled, their state is interdependent, which means that changing the state of one particle affects the state of the other.

5. Wave function collapse:

In quantum mechanics, the wave function describes the state of a particle. When we take measurements on particles, the wave function collapses, which means that the state of the particles becomes the state that we measure, a process that is very important in quantum mechanics because it describes how we get information from quantum systems.

Quantum mechanics is a physical theory that describes the microscopic world, and it is one of the most important scientific discoveries of the 20th century, and the fundamental principles of quantum mechanics are the basis of this theory, which describes the behavior and properties of particles at the microscopic scale.
