Question

What is the unification of the theory of gravity?

+Extra question - Why is the sky blue?​

Answer 1

Answer:

Unified field theory,, in particle physics, an attempt to describe all fundamental forces and the relationships between elementary particles in terms of a single theoretical framework. ... Then, in the early part of the 20th century, Albert Einstein developed general relativity, a field theory of gravitation.

Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. ... More of the sunlight entering the atmosphere is blue than violet, however, and our eyes are somewhat more sensitive to blue light than to violet light, so the sky appears blue.
