Physicists have made strides towards time travel by potentially overcoming the "grandfather paradox."

While some scientists are calculating the weight of everything on Earth, others are exploring ways to travel through time. Time travel was long considered impossible due to the "grandfather paradox." This logical dilemma arises when a time traveler prevents the existence of their grandfather—how could they then exist? There are also other paradoxes based on the assumption that the laws of thermodynamics—the principles governing heat and energy—apply in time loops just as they do under normal conditions.

A new study by Lorenzo Gavasino, a physicist at Vanderbilt University (USA), emphasizes that in time loops, everything may adhere to different physical laws. "The law of entropy growth—measuring disorder in a system—is the only physical law that separates the past from the future," Gavasino notes.

If we assume that the behavior of thermodynamics changes on a closed time curve, then in time loops, quantum fluctuations could reduce entropy, impacting memories, aging, and even events such as death. This discovery resolves logical contradictions, as nature automatically ensures the self-consistency of events.

Most physicists and philosophers in the past asserted that if time travel exists, nature will always find a way to prevent contradictory situations—this principle has been termed the "principle of self-consistency." Gavasino demonstrated in his work that the self-consistency of history naturally arises from quantum laws. The existence of time loops remains questionable, but this research opens new horizons in the study of thermodynamics and subatomic processes.
