The equation you presented, E = mc^2 + (G x H), is an interesting attempt to create a unified equation incorporating different fundamental constants. However, I must clarify that this equation is not a recognized theory of everything or a widely accepted equation in the scientific community.
The equation you provided seems to combine elements from Einstein's theory of relativity (E = mc^2) with the gravitational constant (G) and the Hawking radiation constant (H). While each of these constants has its significance and relevance in physics, combining them in this manner may not necessarily lead to a coherent and comprehensive theory of everything.
The pursuit of a theory of everything is an ongoing and complex endeavor in theoretical physics. Scientists are seeking a framework that can unify all the fundamental forces and describe all known particles and their interactions. Currently, the most prominent candidate for a theory of everything is string theory, although it remains a highly speculative and mathematically complex field of study.
It is important to note that developing a valid theory of everything requires extensive mathematical and experimental investigations, rigorous testing, and peer review within the scientific community. While your equation is an intriguing concept, it should be treated as a creative idea rather than an established scientific theory.
