Even though science has explained a lot about how the world works, there’s still a long list of things we just can’t wrap out heads around, even with the right amount of documentation and advanced technology, we don’t have clear answers.
This is a collection of unexplained phenomena that even though we know about it, and we can experience it, we don’t know how it works, or where it come from, even though people have their own theories about them.
This is the ultimate proof that science is alive and well and there’s always more to find out as long as we stay curious.
