The final point to be made about modern fantasy is the role that science fiction plays in the genre. Science fiction is often grouped with fantasy even though it explores scientific concepts in our world versus magical concepts in an imaginary world. To be clear, however, the big difference between the two is that science fiction explores scientific concepts that are in our real or pseudo-scientific based on the technology we have in the world today. It then attempts to illustrate for readers the potential (or potential horrors) of that technology based on the different ways it might be used.
