DECEMBER 8 IS PRETEND TO BE A TIME TRAVELER DAY

While most physicists agree time travel is theoretically possible, our current technology and scientific knowledge are not advanced enough to make it a reality.

Albert Einstein's theory of relativity says time is not a constant and can be affected by speed and gravity, so time can slow down or speed up depending on conditions.  This opens up the possibility of time travel.

Wormholes—hypothetical tunnels in space-time that connect distant points in the universe—could potentially allow time travel by creating shortcuts through space and time.  But that’s hypothetical.

According to NASA, the theory of general relativity provides scenarios that would support time travel through wormholes in time and space.  However, a person is unlikely to survive the trip.

Stephen Hawking believed traveling into the future was theoretically possible but was skeptical about traveling backin time.  His "chronology protection conjecture" posits that the laws of physics prevent time travel to avoid paradoxes.

Time travel raises serious ethical questions.  If a time traveler alters a significant event in history, it could have far-reaching effects on the present and future.  This leads to unpredictable outcomes.

If a time traveler uses information about future events to amass wealth or power, this could disrupt the natural course of history.

The concept of time travel has fascinated scientists, philosophers, and storytellers for centuries.

In the Mahabharata (400 BC) there is a story of King Raivata Kakudmi, who travels to heaven to meet the creator, Brahma.  When he returns to his kingdom, he discovers many ages have passed during his short absence.

In Charles Dickens’ 1843 novella A Christmas Carol, Ebeneezer Scrooge is transported back and forth through time to witness various events, leading to his eventual change of heart towards mankind.

In H. G. Wells’ 1895 novel The Time Machine, the Time Traveller builds a vehicle designed to transport passengers forwards and backwards in time.

In 1941 Robert A Heinlen’s short story By His Bootstraps, protagonist Bob Wilson occupies multiple time-frames at once through time travel, interacting with different versions of himself.

In 1963, BBC launched Doctor Who, in which time lord “The Doctor” travels through time and space in his Tardis to save the Earth from alien threats.

In the Back to the Future Trilogy, Marty McFly travels into the future and into the past to rectify and resolve problems.

The Terminator films revolve around a dystopian future where machines have taken over the world. Characters travel back in time to prevent the rise of the machines and save humanity.

In 12 Monkeys, James Cole, a convict from a dystopian future, is sent back to the past to prevent a deadly plague from wiping out humanity.

Hitchhiker's Guide to the Galaxy follows the adventures of Arthur Dent as he travels through space and time with the help of a guidebook for intergalactic hitchhikers.

In Quantum Leap, scientist Dr. Sam Beckett leaps through time, inhabiting the bodies of different people to correct historical mistakes.  The show explores ethical dilemmas and personal challenges of time travel.

In Time Travel for Fun and Prophet, Dan Baker is drawn into the timestream and travels through time and space through a swirling vortex to different eras and places.  He meets fellow time jumpers, visits distant planets, and finds himself searching for food and shelter whenever he lands in a new locale.

He can thank his lucky stars that he meets Freddie, an experienced time jumper who can teach him the ropes.
