AUSTRALIAN PHYSICISTS PROVED TAHT TIME TRAVEL IS POSSIBLE

 

University of Queensland scientists used photons (single light particles) to simulate 

time-traveling quantum particles. Research is at the forefront and the results could 

be dramatic!

Their research, titled "Experimental Simulation of Closed Time Curves", is published 

in the latest issue of Nature Communications. The grandfather paradox states that if 

a time traveler goes back in time, it could accidentally prevent his grandparents 

from meeting, and thus prevent his birth.

However, if he had never been born, he would never have been able to travel back in 

time in the first place. The paradoxes are largely caused by Einstein's theory of 

relativity and its solution, the Gödel metric.

How relativity works Einstein's theory of relativity has two parts: general relativity

and special relativity. Special relativity assumes that space and time are aspects of 

the same thing, known as space-time continuum, and that time can slow down or speed 

up, depending on how fast you are moving, compared to something else.

Gravity can also bend time, and Einstein's theory of general relativity suggests 

that it would be possible to travel back in time following a space-time path, that 

is, a closed time curve that returns to the starting point in space, but arrives at a 

precedent time.

In 1991, quantum mechanics was expected to avoid some of the paradoxes caused by 

Einstein's theory of relativity, since quantum particles behave almost outside the 

realm of physics.

"The issue of time travel is present at the interface between two of our most 

successful but incompatible physical theories: Einstein's general relativity and 

quantum mechanics," said Martin Ringbauer, a doctoral student at the School of 

Mathematics and Physics of UQ and main author of the article.

"Einstein's theory describes the world on a very large scale of stars and galaxies, 

while quantum mechanics is an excellent description of the world on a very small 

scale of atoms and molecules."

Time travel simulation
Scientists simulated the behavior of two photons that interact with each other in two 

different cases. In the first case, a photon passed through a wormhole and then 

interacted with its older self. In the second case, when a photon travels through 

normal space-time and interacts with another photon trapped inside a curve of the 

timeline closed forever.

"The properties of quantum particles are" fuzzy "or uncertain to begin with, so this 

gives them enough room to avoid inconsistent time travel situations," said co-author 

Professor Timothy Ralph. "Our study provides insights into where and how nature might 

behave differently from what our theories predict."

Although it has been possible to simulate time travel with tiny quantum particles, 

the same may not be possible for larger particles or atoms, which are groups of 

particles.
