Scientists have made an important discovery on whether time travel is real.

The world of science and fiction have been fascinated about the possibility of past and future travel for years. And now scientists could have better understanding of how it works and what could be possible. New research has now ruled out out the concept of going back in time after researchers found the universe can only go one way. The study looked at light and its relationship with other things around it. But because the concept of time is now being looked at in a different light. Research now suggests going backwards in time, a dream popularised in films such as 'Back to the Future,' is impossible.

The speed of light can alter when it passes through a physical item, but a breakdown of what happens to the object has never been known definitively. Matias Koivurova, assistant professor from the University of Eastern Finland leads the analysis in journal Optica. It resulted in new answer which argues the universe has one dimension in space and another separate one in time. Scientists posted a solution which relies wholly on time moving only forwards in the universe.

Koivurova said: "Basically, I found a very neat way to derive the standard wave equation in 1+1 dimensions. The only assumption I needed was that the speed of the wave is constant. Then I thought to myself: what if it’s not always constant? This turned out to be a really good question."

Professor Marco Ornigotti, who led the study added: "There is this very famous debate in physics, which is called the Abraham-Minkowski controversy. The controversy is that when light enters a medium, what happens to its momentum? Minkowski said that the momentum increases, while Abraham insisted that it decreases.

"We found that we can ascribe a ‘proper time’ to the wave, which is entirely analogous to the proper time in the general theory of relativity." This means that if time only moves forwards time in the universe, revisiting the past could remain the stuff of fiction.

The Mirror earlier reported now a TikToker who previously claimed to be a "time traveller from the year 2671" said he knows when the world's worst natural disasters will strike over the next 12 months or so. Eno Alaric, who is also known as @radianttimetraveller on TikTok, has gained more than 26,000 followers for posting warnings about supposed future events. The creator has previously issued warnings about twin planets colliding with Earth, alien visitors, and even the start of World War 3.

Now, the self-proclaimed time-warper has issued four warnings about supposedly impending mega-natural disasters. The claims included a 750ft-tall mega tsunami, and a 17-mile wide tornado. The TikToker posted: "ATTENTION! I am a real time traveler, these are the worst natural disasters to come in the next 6 months. In my time, 2024 is considered the worst year in history in terms of natural disasters."
