Science fiction films often show ships or even ordinary cars with warp engines that work by warping space and time. Whoosh — and you've traveled a thousand light years. Is it really possible to create such devices? The lecture on daring space travel was given by Alexey Semikhatov, Doctor of Physical and Mathematical Sciences, Head of the Laboratory of Fundamental Interactions Theory at the Lebedev Physical Institute of the Russian Academy of Sciences, host of popular science programs, and author of films and books. During the lecture, Alexey Semikhatov considered the prospects for flights on an "ideal" rocket, taking into account the effects of the special theory of relativity — time dilation and unlimited growth of the energy of motion. The lecture was held as part of the Kstati science festival from the Institute of Astronomy and Evolution.
