Mirage Phenomenon: Illusion or Cosmic Reality?
By Napatradanai
The summer heat often brings about strange optical illusions, one of which is the Mirage phenomenon. As the scorching sunlight hits objects on the road, the heat and glare create an illusion that makes everything appear as if it’s about to burn. However, one curious aspect of this phenomenon is the sudden appearance of a puddle of water on the road, only for it to disappear upon closer inspection. This phenomenon is known as Mirage.
Mirage phenomenon occurs frequently during high temperatures and is related to the refraction of light. It leads to the illusion of sinkholes or reflections on the surface of roads or deserts. The mechanics behind this phenomenon lie in the temperature differences between the object’s surface and the air above it. These temperature variations cause a change in air density, resulting in the refraction of light waves as they pass through different air densities.
The incident light on the object undergoes refraction and reflection when the angle of incidence is wider. This creates the illusion of a mirror or a puddle of water on the road surface. Fascinatingly, humans have adapted the concept of light refraction in various optical devices, including telescopes, microscopes, and cameras. These devices utilize lenses as a crucial component in the refraction process.
In an unexpected twist, scientists from the University of Geneva have presented a theory that questions our perception of the expanding universe. Previously, physicists hypothesized that the universe is continuously growing larger, based on the observed movements of galaxies far away from Earth. However, this new theory postulates that the expansion of the universe might just be an illusion, much like the Mirage phenomenon.
The researchers propose that our understanding of the universe’s expansion has been based purely on imaginative extrapolations and mathematical calculations, without any empirical measurements. By modifying the mathematical equations used to study cosmic expansion, they suggest that what we perceived as an expanding universe might actually be a fixed and flat entity, as predicted by Einstein’s theory.
The theory challenges the cosmic constant, which has long baffled cosmologists due to vast differences between the predicted values from particle physics and observations. While other scientists introduced new particles or forces to address this discrepancy, Lucas Lombriser, a lecturer at the University of Geneva, proposed a different approach.
According to Lombriser’s mathematical interpretation, the universe neither expands nor undergoes any changes in size. Instead, it remains flat and fixed. The appearance of expansion over time is merely a result of the evolution of mass, such as protons and electrons. These masses fluctuate due to the fluctuations in space inserted in space-time, where the cosmic constant is determined. Consequently, the cosmological constant varies with time as particle masses change, mimicking the Mirage phenomenon.
While the theory offers a new perspective on the expanding universe and potentially resolves the conundrum of the cosmic constant, Lombriser acknowledges the difficulty of proving his theoretical model. The study of other cosmic mysteries, such as dark energy and dark matter, also presents challenges for future research.
For now, Lombriser’s theory is merely one among many cosmic theories. However, it raises intriguing questions about our understanding of the universe. Could dark energy and dark matter be equally enigmatic entities that require a new perspective to uncover their secrets? As we delve further into the observable universe, perhaps the Mirage phenomenon holds the key to unraveling these unsolved mysteries.
