What is the biggest unsolved problem in physics?

Quantum Gravity The biggest unsolved problem in fundamental physics is how gravity and the quantum will be made to coexist within the same theory. Quantum Gravity [1] is required to make the whole of physics logically consistent.

What is still unsolved in physics?

There are still some questions beyond the Standard Model of physics, such as the strong CP problem, neutrino mass, matter–antimatter asymmetry, and the nature of dark matter and dark energy. …

What is the biggest unsolved problem in Fundamental Physics?

The biggest unsolved problem in fundamental physics is how gravity and the quantum will be made to coexist within the same theory. Quantum Gravity is required to make the whole of physics logically consistent. The problem is that quantum physics and general relativity already overlap each other’s domains, but do not fit together.

What is the problem of time in physics?

Problem of time: In quantum mechanics time is a classical background parameter and the flow of time is universal and absolute. In general relativity time is one component of four-dimensional spacetime, and the flow of time changes depending on the curvature of spacetime and the spacetime trajectory of the observer.

What are the problems with the standard model of Physics?

There are still some questions beyond the Standard Model of physics, such as the strong CP problem, neutrino mass, matter–antimatter asymmetry, and the nature of dark matterand dark energy. [1][2]Another problem lies within the mathematical frameworkof the Standard Model itself—the Standard Model is inconsistent with that of general relativity,

What is an example of a practical problem in physics?

Problems in physics arise in difierent ways, of which the two main cat- egories are technical and conceptual. An example in the former class is the solution of the N-body problem in Newtonian mechanics as applied, for ex- ample, to the solar system.
