About :

Scientific constructors: http://physfrompobed.ru/fizikits The competition is over! The results were announced on March 26 at 15:00 in the VK group (https://vk.com/physfrompobed). Thank you all for participating! Why do we think the Universe is infinite? What if it has a finite size? Maybe it is closed, or has a completely unusual shape? Why might the Universe look like a donut or a torus, how does the speed of light affect this, and is it possible to go around the Universe in a circle? All this is in the issue! Timecodes 00:00 Scientific constructors 00:54 Introduction 02:00 Observable part of the Universe 03:22 Is the Universe closed in on itself, or not? 05:55 Topology 07:34 The shape of the Universe 09:00 Final words I'm on VK: https://vk.com/pobedos I'm on Instagram: / pobedinskiy Useful links: About a closed world: https://habr.com/ru/post/388825/ The minimum size of the Universe: https://www.forbes.com/sites/startswi...
