Great mysteries that science has not been able to explain

Science has no explanations for everything. Great mysteries, from near-death experiences to ghosts or the sighting of UFOs continue to attract the curiosity of experts and researchers.

Our planet, life and the reality that surrounds us are full of great mysteries, enigmas that have attracted the curiosity of entire civilizations and to which religions, superstition, research and science have tried to find an explanation, today still unanswered. Surely you, as a good human on foot, have also asked them. Is there life after death? Are there spirits? Are UFOs watching us? Is time travel possible? Is the universe infinite?

Of course, these issues and the partial light that science has thrown behind them would give to write an encyclopedia. Today we will briefly focus on some of them and how scientific research has not yet been able to unravel the mystery around them. These are the biggest unknowns that keep humanity in suspense today.

The sense of intuition

Whether we call it visceral feelings, a "sixth sense" or something else, we have all experienced intuition at one time or another. Psychologists point out that we collect information subconsciously about the world around us, which leads us to perceive or know information apparently without knowing exactly how or why we know it. The problem for science is that cases of intuition are difficult to prove or study.

Recent studies have taken some steps to delve into this gift, until then considered a spiritual gift or a psychic power especially linked to women. Psychiatrist Peter C Whybrow recognizes that intuition is a main component to tune the brain, calling it a reflexive self-knowledge governed by a preconscious neural network.

This network is informed by previously learned patterns that help determine moral rules, acquired habits and beliefs. As happens when we learn to ride a bike, ski or catch a ball, after the repetition, we archive this information in our brain and we no longer think about the matter, releasing cognitive space to pay attention to other things. It seems that when a recognizable pattern emerges, intuition emerges in the light spontaneously.

The existence of telepathy

Around telepathy or "wireless communication" between two human brains, science has revealed that it is not plausible from the point of view of physics, since there is no brain section capable of acting as a transmitter or receiver of distance communications or there is sufficient electromagnetic power, but the debate and doubts persist around the phenomenon.

The experiments on telepathy have not yielded conclusive results: the 88 "ganzfeld experiments" carried out between 1974 and 2004 showed a telepathic success rate of 37% -which was repeated at 34 %-, while the biochemist Rupert Sheldrake of the University Cambridge, conducted a telepathic experiment between 2003 and 2004 with 571 attempts at telepathic communication with 63 volunteers and a success rate of 41%.

Another inconclusive experiment was conducted by Montaque Ullman and Stanley Krippner of the Maimonides Medical Center in Brooklyn (New York), focused on telepathic transmission during sleep. The results suggested that in some cases the image that was in the sender's mind appeared in the recipient's dream.

Roger Penrose, an expert physicist and mathematician in the Theory of Relativity, has underlined the possible existence of a quantum biophysics of the mind in a thesis that opens doors for a new field of research.

However, there is still much to be investigated regarding telepathy, telekinesia and parallel phenomena such as premonitory dreams.

Ghosts and spirits

From Shakespeare's play "MacBeth" to the NBC program "Medium", the spirits of the dead have a long presence in various cultures, religions, artistic creations and folklore. Some people have even claimed to communicate with deceased living beings or have paranormal experiences with ghosts.

Science has not been able to solve all the enigmas linked to the presence of spirits, although it has been able to contribute to the discussion explanations such as that the infrasound, located between 7 and 19 Hz, can cause pain, fear, irritation and panic in certain individuals, that the electromagnetic fields - also associated with the presence of ghosts - are due to the geological conditions of the place or that the movement of the ouija is due to two phenomena: the predictive tendency of the human brain and the loss of the sense of agency, as revealed a study carried out by a group of researchers from the University of Aarhus in Denmark.

The "ideomotor effect" also plays its role is a psychological phenomenon in which a subject performs supposedly inexplicable movements such as applied kinesiology, psychography, dowsing, the so-called "facilitated communication" and the ouija. You can expand the information about him here.


There is no doubt that there are UFOs (unidentified flying objects); Many people see things in the skies that they cannot identify, from airplanes to meteors. However, many people have attributed these flashes or visions with spaceships, UFOs and aliens from other civilizations, generating numerous material, specialized programs, conspiracy theories and even left for sightings.

Science has not yet been able to confirm or prove with the scientific method if any of these mysterious appearances or lights are due to the arrival of aliens to our inhabited planet, and many of them are linked to aerial military experiments. In 1977, Peter Sturrock, a professor of space science and astronomy at Stanford University, sent 2611 questionnaires about UFO sightings to members of the American Astronomy Society. Of the 1,356 responses, 4.6%) reported having witnessed or recorded unexplained aerial phenomena, a rate that corresponds to the number of sightings that were never resolved.

Also within the scientific community itself there is dissent of positions: a Harvard astronomy professor, Abraham Loeb, recently claimed that an extraterrestrial spacecraft has surpassed the orbit of Jupiter in the direction of the Earth and that 'Oumuamua', the space object seen in 2017, it is a UFO sent by another civilization.

Experiences near death and life after death

People who were once close to death have sometimes reported on several mystical experiences with different variables - from seeing the light at the end of the famous tunnel, meeting with loved ones, having extra-bodily experiences or experiencing a sense of peace.

Skeptics suggest that experiences can be explained as natural and predictable hallucinations of a traumatized brain, while some scientists have associated NDEs with the experience induced by the potent serotonergic, N, N-Dimethyltryptamine (DMT), a molecule present in the brain and that we secrete in small doses when we dream and in large at birth and death.

The DMT is a powerful psychedelic compound - which at the pharmacological level belongs to the triptamine family - discovered in ayahuasca - whose consumption is linked to various indigenous and Amazonian cultures. An investigation conducted at Imperial College London and collected by the Frontiers in Psychology magazine, has revealed a great similarity of perceptions among those who have had an NDE and healthy volunteers who have been given DMT.

On the other hand, a study of people in cardiac arrest in 2015 found that when the heart is dying, it receives signals from the brain that tries to stay active. The number of signals could be responsible for near-death experiences, according to the researchers. However, this area remains, despite the timid advances, one of the great mysteries facing science today.
