Dilater et ralentir le temps : la physique pourrait-elle un jour nous permettre de rajeunir ? (2026)

In a recent interview, physicist Fabrizio Bucella addresses the question of whether it will be possible to reverse aging through physics. Bucella clarifies that while it is theoretically possible to slow down time, it is not feasible to reverse the aging process. This concept is based on the idea that time dilation occurs when individuals travel at extremely high speeds, approaching the speed of light. As a result, time passes more slowly for them compared to those who remain on Earth. However, Bucella emphasizes that this phenomenon does not allow individuals to physically age backward. Instead, it creates a discrepancy in the perception of time, where those who have traveled at high speeds experience less time passing than those who have remained stationary. Bucella's insights highlight the intriguing possibilities and limitations of physics in our understanding of time and aging.
