Are we able to apply Quantum Mechanics to a Universe Prior to the Big Bang? Or would such mechanics require an entirely new set of formulas?

How does Quantum Gravity fail when spacetime curvature is very high? It sounds to me like a plane that is flying straight up and then stalls.

Quantum mechanics is a branch of physics that studies the behavior of particles at a subatomic level. It is used to understand the fundamental laws that govern the universe, including the Big Bang. The principles of quantum mechanics can help explain the initial conditions of the universe and how it evolved from a singularity.
Quantum fluctuations are small variations in the energy levels of particles at a subatomic scale. These fluctuations are thought to have played a crucial role in the early universe, as they may have caused small perturbations in the otherwise smooth distribution of matter and energy. These perturbations eventually led to the formation of galaxies and other structures in the universe.
Currently, there is no consensus among scientists about what, if anything, existed before the Big Bang. Some theories suggest that the laws of physics, including quantum mechanics, may break down or behave differently in the extreme conditions before the Big Bang. Therefore, it is currently not possible to use quantum mechanics to understand what existed before the Big Bang.
The uncertainty principle, which states that the position and momentum of a particle cannot be known simultaneously with complete precision, applies to the Big Bang in the sense that it is impossible to know the exact conditions at the moment of the Big Bang. This is because the energy levels and other properties of particles are constantly fluctuating at a subatomic level, making it impossible to determine their precise values at any given time.
There are several theories that attempt to combine quantum mechanics and the Big Bang, such as loop quantum cosmology and string theory. These theories propose different ways of understanding the very early universe, taking into account both the principles of quantum mechanics and the laws of gravity. However, these theories are still being researched and debated, and there is currently no consensus on a single unified theory that combines quantum mechanics and the Big Bang.
