#Quantum World that is “Quantum Mechanics” also known as “Quantum Physics” or “Quantum Theory”.

# In Classical Physics, quantum mechanics only validated to macroscopic levels.

# But quantum mechanics differs from classical physics, according to quantum mechanics energy, momentum and restricted to other discrete values.

# Quantum mechanics rose with the rose of a Max Plancks solution for “Black Body Radiation” and Albert Einstein’s “Photoelectric Effect”. Werner Heisenberg, Max Born and Erwin Schrodinger also profoundly conceived the notable contribution in quantum mechanics.

The first equation is a Schrodinger’s equation and second one is Klein-Gordon equations.

# According to Planck’s equation each energy element is proportional to the frequency.

i.e.

where h is Planck’s constant and E is the energy, f is frequency.

# There are various methods and process those define quantum mechanics and it also give rise to an many world interpretation (that is our universe is not alone and have one of the few in many universes).

# Currently gravity is based on “Albert Einstein’s general theory of relativity” which is formulated with the Classical Physics.

# Quantum Gravity is generally used to describe the gravitational field and unite all forces in a single force.

# In Quantum Theory, it gives rise to a String Theory.

# String Theory however on the other side try to unify gravity with other fundamental forces such as quantum loop.

# In above diagram, various fields have their won meaning but when come to end “Quantum Gravity” stuck the mind of everyone.

# Standard Model of Physics yet is unable to find the GUT ( Grand Unified Theory) and still facing a problem of “Gravitons” (that is 2-spin massless particles).

# In Kaluza-Klein Theory, five dimensional theory combined with the gravitation and electromagnetism as it generally appears in String Theory.

# There are many ways to define Quantum Gravity such as ‘”Quantum Loop Gravity”, “Time”, String Theory” , Nonrenormalizability of Gravity and many others ways.

# Quantum Gravity is no the end of the ultimate reality as this is still a smaller beginning.
