The possibility of time travel has occupied both great scientific minds and sci-fi lovers for quite a long time now. Despite the fact that it is considered impossible by most physicists, there are still theories that could really work. Here are 5 most interesting ones:
1. Cosmic strings
Cosmic strings are hypothetical topological defects in the space-time fabric, still remaining from the formation of the universe. With their help, in theory, a field of closed timelike curves can be formed, allowing travel into the past. Some scientists suggest that cosmic strings can be used to construct a time machine. If two cosmic strings get close to each other or a single string reaches a black hole, Continue reading
Black holes are one of the most frightening phenomena that exist in space. Their gravitational force is so strong that they distort space and time beyond possible limits.
Therefore it begs a question what could happen if such a monster suddenly appeared or traveled to the vicinity of our solar system?
Before answering this question, let us first clarify some other questions. At what distance would it appear? Where would it come from? How massive would such a black hole be? Continue reading

Everyone knows the saying that the eyes are the mirror of the soul. Now it seems that their relationship with the brain function is proved. The slightest eye movement can reveal information about the personality and behavior of a person, claims a new study.
Researchers from the Johns Hopkins University found that rapid eye movements show impatience and inability of self-restraint.
Understanding how the brain perceives the time can explain why the decision-making process is more difficult for people with neurological disorders such as schizophrenia or for people who have suffered a head injury. Continue reading
Deja vu is not an illusion, it is something that you have already experienced in your unconscious fantasies. Believe if you will, or do not believe it. This was already mentioned a hundred years ago by the “great and terrible” Freud, and many subsequent studies have only confirmed his hypothesis.
The phenomenon called deja vu is the feeling of something “already experienced” and, according to Freud, is remembrance of an unconscious fantasy. And since this fantasy is never conscious, during a deja vu moment it is impossible to “recall” something that seems to have already been already perceived.
These strange dreams
We begin with a bit of explanation. Along with the conscious fantasies, unconscious fantasies can exist, they are simply called daydreaming. Commonly, they express Continue reading
The Perimeter Institute in Ontario, Canada, is a research center dedicated to studying the underlying concepts of Physics. A prominent personality of the Foundation, Lee Smolin, one of the main ambassadors of loop quantum gravity, which is an alternative to string theory point of view on the unification of the fundamental forces in Nature, recently gave a speech on the nature of time, a central issue in the understanding of nature itself.
Smolin’s vision is different from the prevailing view that time is a human construct or an illusion in the image we have of the universe. Continue reading
Deja vu is one of the little-known and mysterious phenomena of our psyche. Many people sometimes feel that a situation in their life has already been experienced before in all the details. But how and when? This phenomenon is called déjà vu, which in French means ‘already seen’. It is a condition in which a person feels that once he already experienced a situation of the present, but the feeling is not associated with a specific moment of the past, but refers to the past in general.
Deja vu is quite common. Psychologists believe that 97 % of people have experienced it at least once. Sometimes people are afraid of deja vu and worry about their mental health. What lies beyond human understanding, always frightens us.
The reasons that cause the phenomenon are still not clear. It might be caused by the processes in the parts of the brain associated with memory and perception. There is a hypothesis that sometimes the perceived information gets to the memory areas sooner than to the area of the primary analysis. Thus, the brain, comparing the situation with its ‘neurocopy’ already received by the memory, concludes that it already happened before. Continue reading
Over the last decade great attention to the functioning of the cerebral hemispheres and its effects on the process of learning was paid. This interest has to do with the fact that traditional teaching models are based on the functioning of the left hemisphere i.e. the development of language and logic, without taking into account the characteristics of the right hemisphere, such as intuition, spontaneity, and imagination.
Although the famous French mathematician Poincare argued that “the logic proves but the intuition creates” and although the Hungarian scientist Michael Polanyi talked about mental beauty and passion in the process of knowledge discovery, only recently science began to recognize the role of Continue reading
In science fiction (such as “Star Trek”), teleportation is a usual thing. But how much time and effort is necessary to submit the data required for human teleportation? Students at the Physics Department of the University of Leicester Declan Roberts, James Nelms, Suzanne Thomas and David Starkey decided to answer this difficult question.
The students found that the energy required for teleportation of one individual depends on the bandwidth, which automatically means less time, but the increase in power consumption.
In their work, the students explored the possibility of teleportation of one person on the Earth’s surface into space orbit. Continue reading
The universe is mysterious, and the more science learns about it, the more amazing it seems to be. When looking at all the theories presented here, reader can simply burst into laughter. But what could be more bizarre than something already known to us?
1. Everything we are surrounded by is the “The Matrix”
Many saw the film where the main character (Keanu Reeves) learns with astonishment that the world around him, “The Matrix”, is something resembling a ghetto created for people by computer intelligence. This is, of course, science fiction, but there are scientists who are ready to take this idea seriously.
Nick Bostrom, a British philosopher, has suggested that our whole life is a very complicated game, just like the popular The Sims game: the development of the video game industry could enable us to construct our own world realities, and everyone will live forever in this isolated virtual reality. If this happens, there is a possibility that our world is built based on Continue reading
