The Sensation One Second Before Death, Science Does Not Know

In reality, large meteorites cause massive destruction and fires, and movies ignore the physical laws where fragments and sandstorms devastate the surrounding area. A large meteorite should become a fireball, causing widespread destruction, and fragments and sandstorms should lay waste to the surroundings.

In movies, buildings next to the impact site remain intact two weeks after a meteorite falls, but in reality, large meteorites fall as fireballs, causing massive destruction and fires, and the tremendous fragments and sandstorms generated upon impact devastate the surrounding area.

When a massive meteorite enters Earth's atmosphere, it ignites due to frictional heat.

Dust and ash ejected during the impact cover the sky, blocking sunlight and causing a rapid drop in temperature, leading to an ice age. This results in plant death, causing oxygen depletion and food resource scarcity, increasing the risk of human survival crises and wars.

Slightly altering an asteroid's angle from afar can prevent a collision upon its arrival at Earth.

This method involves spraying white paint on an incoming asteroid to increase its light reflectivity. White reflects all types of light, and the pressure exerted by light, or light pressure, can subtly modify the asteroid's direction of travel.

By tilting the asteroid's orbit at a small angle when it is far from Earth, it is possible to avoid a collision when it reaches Earth.

Organisms are designed to have reduced energy efficiency for survival after reproduction. This is presumed to be the basis for the human biological design limit, set around the average lifespan of 30 years in the Paleolithic era.

From this perspective, life after the warranty period is bonus time not included in the biological plan.

Aging occurs as 'epigenetic markers,' which allow cells to select only necessary information while sharing DNA, accumulate. Currently, technology to reset these markers like a fertilized egg is being researched at the individual cell level.

DNA is shared by all cells, but each cell has epigenetic markers that select only the necessary information. These markers accumulate over a lifetime and influence aging.

At the fertilized egg stage, these markers are reset, and research is underway to artificially control this to revert cells to a youthful state. Cell-level reprogramming technology is currently only feasible at the individual level.

The scientific community remains cautious about whether AI advancements will accelerate the resolution of scientific challenges.

Heart disease strikes without warning, making immediate action essential. Thanks to his wife's persuasion, he received night treatment and successfully underwent stent surgery.

After death, the atoms that composed our bodies scatter and rearrange into other substances in the world. Physically, atoms do not disappear; thus, one can find comfort in interpreting the death of a loved one as a process of atomic recombination.

After a person dies, the atoms that made up their body decompose and form other substances in the world. Physically, atoms do not disappear but are constantly rearranged. Interpreting death as the scattering and recombination of atoms can bring psychological comfort.

Science draws conclusions based on material evidence. The afterlife is beyond the scope of science because there is no physical evidence.

Near-death experiences, which should be approached from the perspectives of neuroscience and psychology, cannot be objectively proven or reproduced.

Science begins with the honest attitude of admitting what it does not know.

Professor Kim Sang-wook clarified the limitation that science can only study subjects for which data exists.

The afterlife, completely devoid of data obtained after death, cannot be a subject of scientific study and is likely to remain an unknown realm forever. Science is just one of many tools to understand the world and does not perfectly explain all phenomena.

Professor Kim Sang-wook presented scientific hypotheses regarding the feelings of happiness and recollections of the past reported during near-death experiences.

Near-death experiences are mainly attributed to hallucinations caused by oxygen deprivation, endorphin release, or the final activation of brain cells just before death, leading to memory recall.

These explanations are merely scientific hypotheses, and he also cautioned against the tendency for near-death experience stories to become stereotyped.

Professor Kim Sang-wook acknowledged that UFOs, meaning 'unidentified flying objects,' refer to the reality of flying objects whose identity is unknown.

However, he dismissed conspiracy theories that the U.S. reverse-engineers UFOs to advance technology, or theories of alien visits to Earth, due to a lack of evidence and the immense distance between Earth and alien civilizations, making visits highly improbable.

Professor Kim Sang-wook divided the world into natural and human realms, identifying humans, not nature, as the entities that deceive us.

Understanding the self-existing laws of nature is the first step to objectively viewing the world and avoiding errors.

Even phenomena like sitting in an everyday chair are considered in terms of their fundamental principles. In a rapidly changing era, efforts are needed to capture unchanging values.

The oldest chair artifacts appeared in the Neolithic era, and ancient Egyptian pharaohs' chairs were uncomfortable, lacking ergonomic design.

Chairs were originally not tools for comfort but ostentatious means to display the status of those in power.

With the advent of the Industrial Revolution, forms of labor performed while sitting in chairs became fully established.

Workers operating machines had to remain fixed in one place, and office workers, due to the nature of tasks using only their heads and hands, could secure sufficient workspace with just a chair and a desk.

This change led to an educational culture that associated the act of studying with the endurance of sitting.

Just as white clothes were preferred in the Joseon Dynasty, conceptions about color change with time and culture. The moment value judgments are added to colors, the language of physics is reinterpreted as human language, and experts emphasize that what exists in the universe are only phenomena and facts, not good or bad. They also added that defining certain colors as good or bad is merely a product of the human-made language system.

Just as white clothes were favored in the Joseon Dynasty, ideas about colored clothing change with time and culture. The explanation is that the moment a value judgment is added, it moves beyond the language of physics to become a human-made language.

Given the nature of academia, which builds upon the research of other scholars, accuracy of data and reporting of error margins are essential. Therefore, it is very dangerous to speak idly about what one does not know, pretending to be knowledgeable; it is better to be embarrassed.

Professor Kim stressed that a true expert must clearly recognize the boundaries of their knowledge and confidently admit what they do not know.
