In summary, hidden variables, as referred to in quantum mechanics, have been shown to be inconsistent with experimental observations. Therefore, they do not exist. The concept of dark energy and dark matter is still being debated and researched. Einstein's idea of a "cosmological constant" has been proven to have some validity, with the discovery of dark energy dominating the total mass-energy content of the Universe. However, the true nature of dark energy is still unknown and requires further investigation.

quantum Mechanically optimal for Hidden Variables? and are Microscopic Blackholes, Dark Energy, Dark Matter Part of Hidden Variable( Non Observable) Systems?

If by hidden variables you mean the usual hidden variables referred to in QM, then thoose hidden variables has been shown inconsistent with experimental observations. So there are no hidden variables. I don't know what all that Dark energy/matter is, I've seen different interpretation as to what "dark" energy means. Some seems to think its some exotic form of energy other seems to think its just usual energy which we haven't accounted for yet.

And some think of virtual particles.

What is Dark Energy?

by NASA Goddard Space Flight Center and ScienceIQ.com

Because he originally thought the Universe was static, Einstein conjectured that even the emptiest possible space, devoid of matter and radiation, might still have a dark energy, which he called a 'Cosmological Constant.' When Edwin Hubble discovered the expansion of the Universe, Einstein rejected his own idea, calling it his greatest blunder. As Richard Feynman and others developed the quantum theory of matter, they realized that 'empty space' was full of temporary ('virtual') particles continually forming and destroying themselves. Physicists began to suspect that indeed the vacuum ought to have a dark form of energy, but they could not predict its magnitude.
Through recent measurements of the expansion of the Universe, astronomers have discovered that Einstein's 'blunder' was not a blunder: some form of dark energy does indeed appear to dominate the total mass-energy content of the Universe, and its weird repulsive gravity is pulling the Universe apart. We still do not know whether or how the highly accelerated expansion in the early Universe (inflation) and the current accelerated expansion (due to dark energy) are related.

A Beyond Einstein mission will measure the expansion accurately enough to learn whether this energy is a constant property of empty space (as Einstein conjectured), or whether it shows signs of the richer structure that is possible in modern unified theories of the forces of nature.

1. What are the parameters of the Universe?

The parameters of the Universe refer to the fundamental properties that define the physical laws and characteristics of the Universe. These include parameters such as the speed of light, the gravitational constant, and the cosmological constant.

2. How do scientists determine the parameters of the Universe?

Scientists use a combination of theoretical models and observational data to determine the parameters of the Universe. This involves studying the behavior of matter and energy at different scales and using mathematical equations to describe these behaviors.

3. Are the parameters of the Universe the same everywhere?

While some parameters, such as the speed of light, are considered to be constant throughout the Universe, other parameters may vary in different regions or at different points in time. For example, the density of matter and energy in the Universe may vary from one galaxy to another.

4. Can the parameters of the Universe change over time?

The parameters of the Universe can change as our understanding of the Universe evolves and new observations are made. Additionally, some theories, such as inflation theory, suggest that certain parameters may have changed in the early stages of the Universe's formation.

5. How do the parameters of the Universe affect our existence?

The parameters of the Universe play a crucial role in the formation and evolution of galaxies, stars, and planets. They also determine the behavior of matter and energy, which ultimately affects our existence and the conditions that allow life to exist on Earth.
