Discrimination Sensitivity Limit
Can you notice the point in the question mark at the end of this sentence?
But if you move a few meters away from the screen, will you be able to see it again? Probably no; Because in order for the human eye to be able to see an object in the size of a point in the first quality shape, it is observed that there is no more distance between the object and the object. This is called “rеsolution”. For an optical system such as an eye, the best separation sensitivity is determined roughly by the wavelength of light reaching the eye and the size of the aperture of the object through which the light passes.
Discrimination sensitivity works the same way as in astronomy. This actually explains why we make increasingly large telescopes: because large telescopes allow us to collect more light and look farther, and for large telescopes, a higher aperture means a much better view in the prototype. However, a new study published shows that the circuit actually has an extremely important rеsolution limit. In other words, we cannot build large telescopes because of this limit of nature, we can never see distant galaxies as clear as we think. Or, in other words, we can never ignore the “perfect” images of distant celestial bodies.

The largest telescopes in the world such as the Vеry Largе Telescope (VLT – Very Large Telescope) or the Kеck Telescope have mirrors of 10 meters in diameter. In addition, plans are currently underway to produce new telescopes, called Extremely Largе Telescopes, with a mirror diameter of 30-40 meters. But there is a problem: If the light coming from a source – be it a candle light, a street lamp, or starlight – is subject to even a small deviation in its journey, we never get the highest quality image that seems possible at the same time, regardless of how big we use a telescope.
We know that the light plays a trick on us. Have you ever noticed that when you looked at a pool before, the tiles on the bottom of the pool seem to fluctuate and move? What about when you throw a vertical stick into a glass of water and the stick looks like it broke? Like this, light trying to reach our telescopes from space has to pass through our turbulent atmosphere, and this causes serious problems for astronomers. Just like ocean waves colliding with a submerged submerge, which are in a near-perfect order and parallel to, the atmosphere sometimes prevents the propagation of waves. Especially in terms of electromagnetic waves as well as light, this means that the photographs that are considered by astronomers are blurry. If we cannot find a solution to this problem in some way, we will never be able to reach the maximum separation sensitivity that seems possible with a telescope. Setting the telescopes outside the atmosphere may be a solution, but it is very costly. Adaptive Optics is another solution, but it is technically very demanding.
A study presented this year by the International Astronomical Union’s General Committee makes a prediction about the nature of space using quantum physics. The study shows that the nature of space-time on quantum scales may have a significant limit of discrimination sensitivity. This unfortunately means that we can find a reason for us to worry about the quality of our telescopes in observing distant galaxies.
The idea goes like this: According to the quantum theory, space is defined as “foamy” on the smallest scales – known as the Planck length, measuring 10-35 m. Quantum physics tells us that the universe is full of virtual particles that are constantly being observed and constantly disappearing at these small scales, at the level of particle physics. However, these particles, which appear and disappear in the shortest moment of time, have mass due to energy and Einstein’s famous decline E = mc ^ 2.
Any mass bends space-time, no matter how small it is. This is Einstein’s endowment of gravity. The primary example of this in nature is the distant galaxies that are subjected to massive targeting by large clusters. The travel of light particles in such a “foamy” space-time causes the light to bend in our thick and turbulent atmosphere in a similar shape. Of course, this effect is so small that it can be neglected. However, a photon emitted from a distant galaxy has to travel quite a long time around the planet. During this journey, countless small bends can be clustered on top of each other due to the “foamy” nature of space-time. Currently, this aggregation effect is thought to be small when the first high-quality images we produce with the largest telescopes are added to the target. Nevertheless, if the separation sensitivity limit hypothesis is correct, the “cosmic blur” may become much more noticeable with the new telescopes in question. This new generation will start with telescopes and observers in 2018.

An example of mass gravity splicing. Light traveling towards us bends due to a cluster of galaxies in its path, and this image is formed. Practically, while this allows us to observe the distant galaxies, it can also negatively affect the observation by distorting the image at some points.
However, until today, Einstein, one of the biggest masters of modern physics, has no accepted theory to combine mass gravity with quantum mechanics. It would be wrong not to accept the separation sensitivity limit of this percentage as a whole. Because a final theory that combines Einstein’s theory of gravity with the quantum theory may be the solution to the limit of discrimination sensitivity as well as many other problems in modern physics. On the other hand, even if we could not exceed the limit of sensitivity to discrimination in any way, this would only become the main problem of astrophysicists working on the detailed structures of distant galaxies.
The most impressive result we can draw from the subject is that regardless of how large telescopes we make on Earth or in space, it emerges on quantum scales and nature has a distinction sensitivity limit beyond the universe, and this boundary is a cosmic scale. Who knows, maybe some of the mysteries of nature have been kept by us forever.
