Marvel movies, Rick and Morty, Back to the Future, you name it. Why is Interdimensional travel such a hot topic in media cultures?
"Back to the Future" is about time travel, not interdimensional travel. And the MCU started playing with the idea of the multiverse very recently (just two movies and a series so far). "Rick & Morty" does revolve around interdimensional travel, yes. But it is just one example, and I can't really think of many more. As a matter of fact, time travel is and has been the actual hot topic in media culture. – T. Palomino5 months ago
