Comment le temps peut-il sembler si évident, si intimement lié à notre expérience, et pourtant, depuis des milliers d’années, rester le cauchemar de tous les penseurs qui ont tenté de l’expliquer ?

How can time feel so obvious, so woven into the fabric of our experience and yet, for thousands of years, remain the bane of every thinker who has tried to explain it?
Le concept d’espace-temps offre une description éloquente de la manière dont les événements se produisent.
Les physiciens disent souvent que l’espace-temps « existe », mais qu’est-ce que cela signifie concrètement ? Une confusion entre l’événement et l’être pourrait fausser notre perception de la réalité.
Space-time isn’t an actual object or event, it’s a conceptual framework for understanding reality.
Os físicos costumam dizer que o espaço-tempo “existe”, mas o que isso realmente significa? Uma confusão oculta entre acontecer e ser pode estar distorcendo nossa visão da realidade.
Physicists often say space-time “exists,” but what does that really mean? A hidden confusion between happening and being could be warping our view of reality.
From the birth of Jesus Christ to Newton’s discovery of gravity, great conjunctions of Jupiter and Saturn have many notable connections in human history.
