Based on the latest scientific findings, Time Travel could soon be a reality in the near future.
Scientists from the University of Queensland, Australia, have used single particles of light (photons) to simulate quantum particles travelling through time. They showed that one photon can pass through a wormhole and then interact with its older self.
The source of this time travel conundrum comes from what are called “closed timelike curves” (CTC). CTCs are used to simulate extremely powerful gravitational fields, like the ones produced by a spinning black hole, and could, theoretically (based on Einstein’s theory of general relativity), warp the fabric of existence so that spacetime bends back on itself – thus creating a CTC, almost like a path that could be used to travel back in time.
Although it’s just a mathematical simulation, the researchers emphasize that their model is equivalent to a single photon traveling through a CTC.
The Grandfather Paradox
Think in terms of the ‘grandfather paradox,’ a hypothetical scenario where someone uses a CTC to travel back through time to cause harm to their grandfather, thus preventing their later birth.
Now imagine a particle going back in time to flip a switch on the particle-generating machine that created it – this is a possibility that these physicists say they have shown through their simulation.
Why This Is A High Probability
In my opinion, there is no doubt time travel is possible.
“The maddening part of that problem is that the ability of particles to exist in two places at once is not a mere theoretical abstraction. It is a very real aspect of how the subatomic world works, and it has been experimentally confirmed many times over.”
This particular experiment illustrates how what happens in the present can change what happened in the past. It also shows how time can go backwards, how cause and effect can be reversed, and how the future caused the past.
Perhaps one day, we will have determined the key to this puzzle and be able to observe large objects like cars, humans, apples, and oranges, and perhaps one day we will find a wormhole, or a CTC in space, to conduct actual experiments that go beyond theory. That being said, a lot of what used to be considered theoretical in quantum physics is no longer theoretical, like quantum entanglement.
This amazing image from 1940, showing a man from the future has served to convince millions of people time travel WAS possible.
A Time Travelling hipster! This is the famous photograph that started the new craze for looking for time travelers in old photographs. This hipster’s got totally cool wraparound glasses, is wearing a faded old silkscreened t-shirt of the sort not made until the 1970s, has a pocket-size digital camera around his neck, and a modern haircut. He’s also quite a bit taller than the people surrounding him, reflecting the greater height people have today.
