"The concept of existence when assumed to be eternal, and therefore, there can't be a starting point for existence, nor an end to the universe
"The concept of existence when assumed to be eternal, and therefore, there can't be a starting point for existence, nor an end to the universe
However, it's crucial to consider what existence truly means, social or philosophical understanding doesn't align with how existence is interpreted in the realm of physical science.
Let's explore physical existence in terms of the Planck scale, specifically the Planck length. This scale marks the point where classical notions of gravity and space-time no longer apply, and quantum effects take over. Even before reaching the Planck length, our physical perception becomes ineffective, and we can never fully grasp anything beyond this threshold. The Planck length, approximately 1.616255×10^−35 meters, is defined by physical constants such as the speed of light, the Planck constant, and the gravitational constant. It serves as the limit of physical reality perception.
So, physical reality's inception occurs well before we reach the Planck length, and its end is when it reaches the Planck length. Our physical universe and existence are confined within this Planck threshold. We can't observe or measure anything beyond it, even with advanced technology in the distant future. The Planck length stands as our permanent perceptual limit.
While we may experience gravitational or antigravitational effects from existence beyond our physical perception, such existence holds no meaning within our physical domain because we can't perceive events and time from this imperceptible existence beyond our physical reality.
The notion of a beginning and an end is rooted in our limited perception. The Big Bang and Black Holes, for instance, hypothesize domains beyond our perceptual capabilities. The concept of a beginning and end of physical existence is mathematically possible beyond our perceptible reality.
Therefore, one cannot dismiss the idea of a beginning and an end to existence considering our physical limitations. Furthermore, eternal existence doesn't account for the effects of dark energy and the gravitational influences of black holes, which we can perceive as interactions from the non-existent reality.
It's important to note that the Planck length represents a fundamental limit to our current understanding of physical reality. However, claiming that our physical universe's existence begins and ends strictly at the Planck length might be an oversimplification. While it serves as a lower limit for our perception, it doesn't necessarily define the boundaries of the universe itself.
Furthermore, acknowledging the existence of phenomena beyond our perception, such as dark energy and the gravitational effects of black holes, is essential. These interactions may provide insights into regions of the universe that we can't directly observe.
So it is essential to recognize that scientific understanding of existence and the universe is a complex field that extends far beyond our current comprehension. While the Planck length is a crucial concept, defining the precise boundaries of the universe based solely on it remains a topic of ongoing research and debate. Additionally, accounting for phenomena like dark energy and black holes is crucial in our quest to comprehend the universe fully."

The idea that Gravitation fails at the Planck scale is purely hypothetical and not supported by any physical data whatsoever. There is this conception among convention that there exists this mystical magical line between the 'macroscopic' and 'quantum,' where the laws of Physics go out the window and fall into the realm of absurd hypotheses.
There can be no change in the Laws of Physics as a result of scale, save for the Heisenberg Uncertainty Principle, which places a lower resolution as 2-Planck lengths [or time intervals], not one. That is the 4pi in dxdt>h/4pi. Dirac assigned 4pui as the convention of two native wave cycles, which at the Planck limit is 2-Planck intervals of {Lp, tp}.
Gravitation, as a result of sign, takes effect at exactly 2-Planck intervals, as Bekenstein defined this as the limit at which one coalesces with a Black Hole Horizon. Gravitation thus is valid at greater than or equal to 2-Planck lengths. There is no magical nor mystical line other than the Bekenstein-Limit; which is the only sensible and Valid Theory on the subject.
The notion of the cosmos being infinite is an even more rarer hypothesis. The universe by convention is regarded as finite: from the 'Big Bang' [lower limit] to the present [upper limit]. There is nothing beyond the present, the future does not exist.
Just the very fact that the upper limit is the present absolutely defines the universe as finite, any system bound by a limit on either side is finite. There is nothing beyond the immediate present, which is a range of values throughout the cosmos, as perceived from our Preferential Frame of Reference here on Earth. Meaning, the upper limit of the present is and was a very different value in the galaxy Andromeda, 2-million lightyears away, or ago, what have you.

Exploring the limits of existence and the unknown in the universe is an interesting topic in theoretical physics and astronomy. There are several theoretical concepts and models that discuss the limits of existence and attempt to explain phenomena that go beyond our current ability to understand and observe. Let's discuss some of these concepts:
1. Planck length: The Planck length is considered one of the smallest possible lengths in the universe according to theoretical physics. It is symbolized by "l_P" and is estimated at approximately 1.6 x 10^-35 metres. It is assumed that nothing with dimensions smaller than this size can be measured or seen. The Planck length may have an important role in studying phenomena intertwined between gravity and quantum physics.
2. The unknown gap: These terms refer to the limited knowledge we have about the universe and its mysterious phenomena. Despite great advances in our understanding of the universe, there are many things we do not yet know, such as the true nature of dark energy and dark matter, the origin and evolution of the universe, and the universe's past before the Big Bang.
3. New physics models: There is a continuous development in theoretical physics to try to explore the limits of existence and understand mysterious phenomena. Among these models, string theory and quantum theory of gravity (black holes) are famous examples. These models seek to unify the fundamental forces of nature and provide a comprehensive description of the universe.
With the development of technology and scientific research, our understanding of the limits of existence and the unknown in the universe may be expanded. This requires continuous improvements in instruments, observations and experiments, as well as continuous interaction between scientists and researchers in different fields.

Besides the Planck length, lP, there exist two other ultimate Matter’s constants– Planck time, tP, and Planck constant, h, though really more fundamental is the fundamental elementary physical action/angular momentum ћ=h/2π. From these constants really the system of “Planck units” is composed.
Really, as that is rigorously scientifically shown in the Shevchenko-Tokarevsky’s Planck scale informational physical model , 3 main papers are
- the ultimate base of Matter is the (at least) [4+4+1]4D dense lattice of primary elementary logical structures – (at least) [4+4+1]4D binary reversible fundamental logical elements [FLE], which is placed in the corresponding Matter’s fundamentally absolute, fundamentally flat, fundamentally continuous, and fundamentally “Cartesian”, (at least) [4+4+1]4D spacetime with metrics (at least) (cτ,X,Y,Z, g,w,e,s,ct), FLE “size” and “FLE binary flip time” are Planck length, and Planck time;
- while everything in Matter is/are some specific disturbances in the lattice.
The utmost fundamental constants above reveal themselves as the mainstream physics “fundamental constants” – standard speed of light, c, and Gravitational constant, G, and the Planck constants above are “derived” in the mainstream as some combinations of the mainstream constants; while really the mainstream constants are combinations of the Planck constants, say, c=lP/tP, i.e. since the disturbances in the lattice are some specific sequences of FLE-by-FLE flips, all disturbances so always move in then lattice, and so in the at least utmost universal 4D space with metrics (cτ,X,Y,Z), only with the speed of light. Photons move only in the 3DXYZ space, and so this fact is directly observable.
Etc., more see the linked above papers, where more 30 fundamental physical, including cosmological, problems are either solved or essentially, i.e. when possible rational ways are pointed, clarified; here only a few notes to what is in the thread now:
- Gravity is fundamentally nothing else than some fundamental Nature force; and - as that at all other, known now Weak, Electric and Strong/Nuclear Forces actions, there are no problems with the Forces’ actions quantization – at quantization of Gravity action really there is no fundamental problems as well;
- including the “quantization” happens/observed now on the QM scale, which is on at least a couple of orders by magnitude is “larger” then Planck scale; including in this case Gravity again doesn’t differ from other Forces; and
- there is no “principal” limitations besides that, again, everything in Matter ultimately exists and happens in the FLE lattice, including, say, the Planck mass particles have “radius”/Compton length be equal to one Planck length, and that are only particles that interact only gravitationally; and by no means that are the GR “black holes”, i.e. some “holes in the spacetime”.
