I recently got a burst of curiosity and had a quick look into what scientists are calling Multiverse. It is a hypothetical set of multiple possible universes that together comprise everything that exists and can exists like space, time, matter and energy (that brief definition alone gave me a headache…but I still find this theory very interesting and I am forcing my brain to understand it) . This also implies the notion of parallel universes, a theory which has proven to not only be a very good subject for a countless number of books and movies that captured our imagination, but also a theoretical possibility.
After I took all these shots and had a proper look at them, the first few thoughts that popped in my mind were space-time, universe, parallel universes.
