How the Cosmological (Gods stretching apart the Universe) can not happen in 6,000 years

The Old Testament records God is stretching apart the heavens 12 times. Modern cosmology calls this the Cosmological Constant.

The cosmological constant's "fine-tuning" refers to the incredibly precise value it holds, a value that's essential for the universe to exist as we observe it. The cosmological constant's value is extraordinarily small, 120 decimals to the  right of zero e.g. 0.00..(120 zeros) then 4. If it were even slightly larger, the universe would expand too rapidly, preventing the formation of galaxies and stars. Conversely, if it were slightly smaller, gravity would dominate, causing the universe to collapse into black Holes and neutron stars.

This fine-tuning raises questions about whether it's a mere coincidence or if there's an underlying reason for this precise value. It fuels discussions about the anthropic principle, which suggests that the universe's properties are constrained by the requirement that it must allow for the existence of observers. In essence, the cosmological constant's delicate balance is a profound mystery, prompting ongoing research and debate within cosmology. This 3 min youtube explores this fine tuning.

Understanding the expansion of the universe involves grappling with the cosmological constant and the vast timescales of cosmic evolution. The idea that the universe could have reached its current size in just 6,000 years presents a significant challenge to our current cosmological models. Here's a breakdown of why:

The Cosmological Constant and Cosmic Expansion:

• What it is:

• The cosmological constant, often associated with "dark energy," represents a form of energy inherent to space itself. It exerts a repulsive force, driving the accelerated expansion of the universe.

• It was originally introduced by Albert Einstein into his theory of general relativity.

• Its role:

• Observations show that the universe's expansion is not constant but accelerating. This acceleration is attributed to the cosmological constant.

• However, the value of the cosmological constant is incredibly small. This means its effect, while significant on cosmic scales, is very weak.

The Problem of Scale and Time:

• Vast Cosmic Distances:

• The observable universe spans billions of light-years. For the universe to have reached its current size in just 6,000 years, it would have had to expand at speeds far exceeding the speed of light.

• This violates the fundamental principle of physics that nothing can travel faster than light.

• The Weakness of the Cosmological Constant:

• The measured value of the cosmological constant indicates a very gradual acceleration. It's a subtle effect that becomes significant over billions of years, not thousands.

• Therefore, the cosmological constant, as we understand it, is far too weak to have caused such a rapid expansion.

• Other Challenges:

• The idea of a young universe (6,000 years old) clashes with a wealth of astronomical evidence, including:

• The age of stars and galaxies, which are measured to be billions of years old.

• The cosmic microwave background radiation, a relic of the singularity, which indicates a universe roughly 13.8 billion years old.

• The red shift of distant galaxies, which indicate that the universe is expanding, and has been for billions of years.

• There are also the problems with the distribution of elements in the universe, which is very well explained by current theory, and billions of years of stellar nucleosynthesis.

In summary:

The current understanding of the cosmological constant and the vast evidence contradicts the notion of a universe that reached its current size in 6,000 years. The cosmological constant's measured value indicates a gradual, long-term acceleration, not a rapid expansion.
