Scientists investigate time travel as a legitimate scientific discipline that has existed since the inception of scientific research into the concept. People can travel through time using specific methods because the universe lets them do so despite their inability to access actual “Time Machines” in their households. Scientists perceive time as a dimensional space which humans can control to produce multiple time-related phenomena.
We Are All Time Travelers
All humans experience temporal movement since they progress through time at a pace of one second for every actual second that happens. Scientists understand time travel as a method to reach the future. The fourth dimension exists for us to travel through because time advances from past to future.
Time is Relative
Albert Einstein established that different people experience time at varying rates. Time can change speed because it depends on both your movement speed and the gravitational force present. Scientists have shown time dilation exists as an established scientific observation.
High Speed Slows Time
Time progresses at a slower pace for you when you travel on a spaceship that approaches light speed compared to time experienced by Earth inhabitants. You would return home after one year but discover that Earth had experienced a passage of decades. You successfully visited the future.
Gravity Warps Time
Massive objects create a gravitational effect which slows down time as it approaches their location. Clocks located at sea level which experience stronger gravitational force will tick slower than clocks situated on mountain peaks. Time moves at its slowest speed near a black hole, which creates an illusion of time having stopped .
The “Grandfather Paradox”
Time travel to the past generates complex arguments which scientists find impossible to resolve. Your existence depends on your grandfather meeting your grandmother. Scientists deduce that time travel to past events cannot occur because the scenario creates infinite logical conflicts.
The “Self-Correction” Theory
Time travelers will encounter limitations since they lack the ability to change previous historical events according to scientific beliefs. The universe contains a system that protects past events from alterations so all your actions will remain as part of the initial timeline.
Parallel Universes
The theory postulates that time travelers who modify prior events will create new alternate universes. A new reality which develops distinct events, will create an alternate way of life, instead of changing your previous life path.
The “Tipler Cylinder Quote”
Theoretical physicist Frank Tipler demonstrated that an infinitely long cylinder would create time loops which enable travel to the past when it spins at close to the speed of light.
Hawking’s “Chronology Protection”
Stephen Hawking doubted the credibility of time travel to earlier moments in history. The “Chronology Protection Conjecture” describes how physical laws prevent time travel to ancient times because they preserve the integrity of time.
Information vs. Matter
Scientists inquire whether we can transmit “information” or subatomic particles through time since human time travel remains unachievable. This theoretical scientific field currently receives intensive research within quantum physics.
The Lack of Tourists
Hawking observed that future time travel should result in present-day visitors from future times if time travel existed. Scientists believe that humans cannot travel to the future because our existing technology lacks time traveling equipment needed to meet future visitors.
