When you think of Science fiction, you think of a lot of futuristic things. The most fascinating topic is alternate future. It almost sounds like Fantasy, but when you think about it, it’s actually really scientific and hard to explain. So instead, think of it like this, you have to two choices and you pick one of them and go along with it. The alternate future is basically is if you would’ve picked the other choice. Another way is that it’s the future that is similar to ours but different.

Alternate future is indeed a really confusing and complicated topic. However, that doesn’t stop it from making amazing stories. Some great examples are The Fallout(series), Superman: Red Son, The incredibles, and Doctor Who. These are set in an alternate future where the world is similar to ours but is different in a way where people have powers and some can time travel.
