Unified Field Theory: Relating Quantum Mechanics & General Relativity

[spidey]

People say that general relativity and quantum mechanics is not yet combined...i have a doubt,photon is the origin of quantum mechanics and light(photons) is bent by heavy mass and is the origin of general relativity...so this is the relation between quantum mechanics and general relativity..i don't know what other relations are we searching for? Or am i missing something?

In general quantum theory is about things which are very small, while gen. rel. is about things which are very massive. When they are needed at the same time, such as inside a black hole or at the big bang, details of the mathematical results are contradictory.

I can understand your confusion about the relationship between general relativity and quantum mechanics. While it is true that these two theories are not yet fully unified, there have been significant efforts to reconcile them.

The idea of a unified field theory, also known as a theory of everything, is to combine all fundamental forces and particles into one framework. Currently, general relativity describes the behavior of large-scale objects, such as planets and galaxies, while quantum mechanics explains the behavior of subatomic particles.

One way to think about the relationship between these two theories is that they are both valid descriptions of the universe, but they operate on different scales. The principles of quantum mechanics apply to the microscopic world, while general relativity applies to the macroscopic world.

However, there are instances where both theories are needed to fully explain a phenomenon. For example, in black holes, where the gravitational pull is extremely strong, both general relativity and quantum mechanics are necessary to understand the behavior of matter and energy.

In terms of your question about the relation between photons and general relativity, it is true that photons, as particles of light, are affected by the curvature of space-time caused by massive objects. This is an important aspect of general relativity, but it is not the only connection between the two theories.

As scientists, we are constantly searching for a deeper understanding of the universe and how different theories fit together. The goal of a unified field theory is to provide a more complete and comprehensive understanding of the fundamental laws that govern our universe. So, while there may still be unanswered questions and ongoing research in this area, the pursuit of a unified theory is an important and exciting aspect of scientific inquiry.
