Time travel is hypothetically(time machine) traveling in the past and future. It is widely recognized particularly in science fiction. Time traveling is impossible because we all travel approximately at the same speed as the clock 1 second per second.
Albert Einstein says that time and space are linked together. He also says that our universe has a speed limit and nothing can travel faster than the speed of light. According to the theory, “The faster you travel, the slower you perceive time” with an experiment for this principle.
Black hole
A black hole is a place in the universe where gravity is so strong that it pulls even light and nothing can’t go out. This happens when a star dies. A black hole is invisible people can’t see. It can only be seen by some special space instruments.
The gravity of a black hole is so strong that everything that comes near the black hole gets pulled in tightly. A clock nearby a black hole ticks slower than one on the Earth so one year of a black hole equals 80 years on the Earth.
Time travel is possible only if the spacecraft is faster than the speed of light.
According to the Albert Einstein
The theory is about the relativity of time and in this theory, time mainly depends on how the observer is moving relative to something else which means a man traveling at the speed of light in a spaceship so his age will be slower than a man who is on earth.
Time travel in Indian Mythology
There are many theories about time travel given by physicists like Albert Einstein, Stephen Hawking, etc. We heard about many incidents of time travel in different scriptures like Hinduism, Greek, etc.
There are four yuga Satyuga, Treta Yuga, Dwapar Yuga and Kalyug and all yuga are equal to one chatur yuga accordingly we are living in Kalyug. In Satyug people were very strong as compared to now, they had higher IQ levels and the ability to time travel. The story of Kakudami and her daughter is very famous.
In this story, there is a king named Kakudami who is looking for a suitable match for his daughter Revati. He got the chance to meet Brahma in Brahm Lok(In Hinduism Brahma, Vishnu, and Shiva work together to destroy, create the universe, and preserve the life cycle of the churning they are called the trinity of life, where Shiva is the destroyer, Brahma is the creator of the universe and Vishnu is the preserver.) Brahma Lok is many years away from Earth.
When the king arrived, Brahma Ji was resting, so he waited for some time & when Brahma Ji came to meet him and he explained his dilemma and wanted his help in choosing the right match for his daughter, Brahma Ji laughed and told him ” All the boys chosen had died & no one was alive since that time (the time of meeting Brahma Ji) 27 chatur yug’s (thousand and thousand years) had passed. (According to Sahastra Yuga Ahariyada Bhramonavida) “1 day in Brahma Loka is equal to 4.32 billion Earth years.” Thereafter, on the recommendation of Brahma, the king’s daughter Revati married Balarama, an incarnation of Lord Vishnu, who will be the brother of Lord Krishna.
Many events in our culture predate Hinduism such as interstellar travel, the use of atomic bombs like the Brahmastra in the Mahabharata, and many more.
Some real-time travel story
Air Marshal Sir Victor Goddard accidentally entered a parallel universe.
This is the story of RAF Sir Robert Victor Goddard
He was a senior commander during World War II who claims to have experienced a “time slip” or “time travel”.
J.H. Brennan wrote in the book “A New Perspective of Time” that in 1935 Wing Commander Sir Robert was sent to inspect a disused airfield at Drem Place in Edinburgh, Scotland. He saw that the airfield was in terrible condition where cattle grazing on the grass that everything had turned into asphalt.
Later that day he was flying back to base, but bad weather forced him to return to the airfield, where he looked down and saw that everything had been changed and looked like the used field facility and field mechanics in blue overalls and four plains in yellow paint were standing there. But in 1935 RAF training aircraft were painted silver or aluminum.
About 4 years later unused airfield was soon revived in 1939 and the training aircraft began to be painted yellow and the mechanics turned into blue overalls.
All this happened exactly, so Sir Robert experienced a time slip or parallel universe.
A man who traveled back in time to become a Wall Street scam artist
February 28, 2003, Andrew Carlssin was arrested by the police on Wall Street trading when he was interrogated, he said that he came from the future 2256 years ago and made $300 to $800 million in just two weeks by trading in 126 stocks and he came from the future so he already knew the stock perform in future But no one believed his words, then after a few days a person pays $1 million for his bail and police gave the bail and after that, he suddenly went missing, till the date no one came to know where he was disappeared.
Many incidents related to time travel were detected in the present also but could not be proved due to lack of evidence. So It may be possible to do time travel in the future but it is only possible when the speed of light is equal to the rate of traveling.
