Lecture by Prof. Krzysztof Meissner from the Department of Particle Theory and Elementary Interactions at the Institute of Theoretical Physics, Faculty of Physics, University of Warsaw, during the Science Café of the Warsaw Science Festival. January 19, 2015 [1h24min] https://wszechnica.org.pl/wyklad/czas... Part I. [45min] The topic of the meeting was time flowing on Earth and its various manifestations. Time may be different for each observer, which is related to its movement and distance from other bodies. Is it possible to determine since when time has existed, or can we even talk about its beginnings? If it is not possible to determine since when time has "flowed", what significance does it have for our image of the world? For centuries, we have been convinced that time flows the same for everyone and is an absolute value for everyone. Is this really the case? Prof. Krzysztof Meissner proves that the world is much richer and flows differently for different observers. Part II. [39min] After the lecture, the audience asked questions about time in relation to quantum mechanics, the theory of gravity, and the cyclic universe. "I expanded the subject of the lecture and I am very moved that so many people wanted to come, and secondly, that they asked such great questions. It is not easy to find out what current physics says about time or quantum mechanics, the image of the universe. This method [of the Science Café – editor's note] seems absolutely excellent to me, because so many people need such contact, but do not know who to turn to and in what form. An organized meeting that has a certain structure, where you can ask questions, is a fantastic way to popularize science," added Prof. Krzysztof Meissner.
