Trecutul și viitorul sunt totuna. La scară cuantică.

Un articol provocator din The Guardian ne îndeamnă să reflectăm la felul în care scara la care privim lucrurile afectează însăși natura timpului, că mărime fizică fundamentală.

Vă las aici doar un citat și fug să îmi comand cartea lui Rovelli.

Time is also, as we experience it, a one-way street. He explains it in relation to the concept of entropy – the measure of the disordering of things. Entropy was lower in the past. Entropy is higher in the future – there is more disorder, there are more possibilities. The pack of cards of the future is shuffled and uncertain, unlike the ordered and neatly arranged pack of cards of the past. But entropy, heat, past and future are qualities that belong not to the fundamental grammar of the world but to our superficial observation of it. “If I observe the microscopic state of things,” writes Rovelli, “then the difference between past and future vanishes … in the elementary grammar of things, there is no distinction between ‘cause’ and ‘effect’.”
