How to measure time ...? And first of all does it really exist? Broadcast on the occasion of the 1st International Congress on Time.

Publicity

Let us ask ourselves all possible and imaginable questions about time. Not the weather, but the passing time (or not). Between the perceived time of our lives, that measured from clocks to atomic precision, that of evolution which exceeds us and that entirely relative of modern physics where ... time does not exist ... there is something to wonder about: how to measure time? and does it really exist?

Program around Time World , International Congress on Time, was held from November 21 to 23, 2019 at the Cité des Sciences in Paris with the astrophysicist Marc Lachièze-Rey and the biologist Purificación López-García.
