Traveling from the present to the past or the future with the help of a "time machine" has excited the human imagination for centuries and has become one of the main themes of numerous science fiction films.
Perhaps to some, the idea of moving in time and space seems absurd, but many prominent scientists believe that one day this will become a reality. Still, do not forget that such experiments over time can lead to unpredictable consequences in the future, because will be directly related to changing the course of history.
TIME TRAVEL IN ANCIENT MYTHOLOGY
If we turn to ancient texts, then we will also find some references to time travel. In Hindu mythology, for example, there is a legend of King Raivat Kakudmi, who traveled back in time to meet the god of creation Brahma. And although this journey did not last long, 108 “yugas” passed on Earth after the king's return, that is, each “south” was equated to 4 million years. Brahma explained to Kakudmi that time flows in different ways in different planes of existence.
The Koran mentions the story of the al-Kahf cave. In 250 AD, a group of young Christians were persecuted for their belief in one God. Then they hid in a cave, where God put them to sleep for as much as 309 years. This story is a variant of the Christian legend about the "seven sleeping youths of Ephesus" with slight differences.
Another legend came to us from the Japanese legend about the young fisherman Urashima Taro, who was invited to the underwater dragon palace Ryujin and stayed there for three days. When the fisherman returned to the shore, he found that 300 years had passed during his absence. The Buddhist text Pali Canon mentions the paradise of thirty Virgins (the place where the gods lived), where one hundred earth years go in one day.

SCIENTIFIC RESEARCH
Perhaps the most famous story of random time travel is the Philadelphia Experiment, which allegedly took place in 1943 to disguise a warship to make it invisible to enemy radars. But something went wrong, and the ship not only disappeared from Philadelphia, but teleported to the port of Norfolk base, England and was in the past for 10 seconds. When the ship reappeared in Philadelphia, the following picture appeared before eyewitnesses: several crew members literally merged with the structure of the ship, others became mentally deranged or completely disappeared without a trace, and still others died of burns, radiation, electric shock and fear. It was rumored that Nikola Tesla was involved in the experiment, but in reality he died before the test was carried out.
Another curious incident occurred in 1960 with the scientist Pellegrino Ernetti, who developed a device called a chronovisor that allows you to see the past. According to his theory, everything that happens in the present leaves an energy trail that can never be destroyed. His invention supposedly could detect, magnify and convert this energy into a picture, like a television showing the events of the past.
In 2004, scientist and engineer Marlene Pohlman tried to patent his method of distorting gravity and time travel. And last year, Wasfi Alshdaifat filed a patent for a space compression and time dilation device that can also be used for time travel.
Tehran inventor Ali Ratsegi said that he has designed a machine that can "look" into the future for 3-5 years. However, at present, the "time machine" developed by Ali Ratsegi does not exist in reality due to the scientist's fears that the Chinese will certainly steal this idea from him. Who knows, maybe his "time machine" showed Ratsegi such a perspective.
One way or another, but theoretically time travel is possible, and scientists are actively working in this direction. The main thing is that such technologies do not fall into the wrong hands and lead to fatal consequences.
