Time is fascinating. The longer we explore its many facets, the more our idea of what is possible and impossible begins to shift. When asked what time actually is, Stephen Hawking gave an answer similar to that of the ancient Greeks, who distinguished between Chronos and Kairos. Chronos refers to measurable, physical time – the ticking of a clock or the turning of the calendar. Kairos, on the other hand, describes a defining moment, a turning point. Much like in our post-pandemic world, there is often a \u201cbefore\u201d and an \u201cafter.\u201d In the context of climate change, humanity now finds itself in such a Kairos moment, one that calls for new questions and new answers to global challenges. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

In quantum physics, time is treated differently than in classical physics. Quantum theory introduces the idea of the smallest possible units of time \u2014 \u201cquanta of time.\u201d These are so unimaginably small that they cannot be measured directly. Still, they play an important role in explaining phenomena such as the uncertainty between energy and position.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
