From millennium-skipping Victorians to phone booth-hopping teenagers, the term time travel often summons our most fantastic visions of what it means to move through the fourth dimension.
One way to achieve time travel into the future would be travelling at the speed of light in space, as first theorised by Albert Einstein.
Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.
As a result, he found that space and time were interwoven into a single continuum known as space-time. Events that occur at the same time for one observer could occur at different times for another.
One would simply have to build a space ship or move by some other means travel at the speed of light, and head out into space.
This video might just help explain:
According to Express.co, the theoretical physicist and string theorist Brian Greene, of Columbia University, said: “You can build a spaceship, go out into space [and travel] near the speed of light, turn around and come back.
The scientific breakthrough says while it is possible to time travel in to the future, the catch is you more then likely would be stuck there.
Although instruments can neither see nor measure space-time, several of the phenomena predicted by its warping have been confirmed.
Einstein’s Cross, a quasar in the Pegasus constellation, is an excellent example of gravitational lensing. The quasar is about 8 billion light-years from Earth, and sits behind a galaxy that is 400 million light-years away. Four images of the quasar appear around the galaxy because the intense gravity of the galaxy bends the light coming from the quasar.
Gravitational lensing can allow scientists to see some pretty cool things, but until recently, what they spotted around the lens has remained fairly static. However, since the light traveling around the lens takes a different path, each traveling over a different amount of time, scientists were able to observe a supernova occur four different times as it was magnified by a massive galaxy.
In another interesting observation, NASA’s Kepler telescope spotted a dead star, known as a white dwarf, orbiting a red dwarf in a binary system. Although the white dwarf is more massive, it has a far smaller radius than its companion.
“The technique is equivalent to spotting a flea on a light bulb 3,000 miles away, roughly the distance from Los Angeles to New York City,” Avi Shporer of the California Institute of Technology said in a statement.
But is it really possible? Just recently WikiLeaks revealed several new hot topics, one which some claim to be about the government and time travel.
Author Alfred Lambremont Webre, who has penned a number of books on time travel, told Daily Star Online: “This leaked WikiLeaks information does not include the secret programs that permit humans to travel backwards and forwards in time.”
He claims the Vatican provided the technology known as “quantum access” to the CIA as far back as the 1960s.
He said: “Quantum Access are deep secrets of the sort that WikiLeaks has not to date chosen to access and reveal.”
He claims the Vatican has a “time-seer” machine which can access “traces” left by past events and view scenes from history.
Apparently, it is made up of a screen with tuning-dials, and is called a “chronovisor”.
The author says it is not as sophisticated as to allow a user to “step into” history, but displays the events on screen as if they had been recorded.
He said: “What the Vatican did is they subcontracted the technology and gave it to the US Pentagon and CIA starting in the late 1960s.
“The CIA immediately saw they could use it for political purposes.
“They set up a program in the late 1960s to gain knowledge about the political future.”
He says it can also look into the future, and it is used to reveal future presidents, such as Donald Trump, in advance, so they can be “groomed for the job.”
Mr Webre suspects it will also have been given to the British secret services.
Is this all true? Maybe, maybe not. While the the secrets between the vatican and the CIA may be up for debate, time travel to the future is still quite possible.
Einstein theorised that if you were to situate yourself on the edge of a black hole, time would pass more slowly.
Prof Greene explains in his Big Think video: “You hang out [next to a black hole] for a while, you come back, get out of your ship and it will be any number of years into the future, whatever you want all depending on how close you got to the edge of the black hole and how long you hung out there.
“That is time travel to the future.”
But time travel has already happened.
Serial ISS resident Sergei Krikalev holds the record for the longest amount of time spent in space with 803 days, 9 hours, 39 minutes under his belt.
The ISS travels at around 7.66 km/s when orbiting around Earth, and due to the high speed and length of time which he spent in space, the cosmonaut actually arrived back in Earth 0.02 seconds in the future thanks to a process known as time dilation.
But what about time travel to the past?
Greene says: “No one has given a definitive proof that you can’t travel to the past.
“But every time we look at the proposals and detail it seems kind of clear that they’re right at the edge of the known laws of physics.
“And most of us feel that when physics progresses to a point that we understand things even better, these proposals just will be ruled out, they won’t work.”
What this video on “possible proof of time travel”.
While the second video was more “entertainment” than scientific it doesn’t mean it isn’t true, however the first video is all factual, … based on science.
