When you write that the wings are made possible by magic did you mean flying with them? Winged humans can technically exist without magic. (Fancy genetic engineering for instance) However if the wings are big enough for a human to fly they need to be huge, meaning around seven meters.

Since you're new here: You should know that a question that is put "on hold" will be reopened if you edit it to fit the criteria. Also you should know that a lot of questions are closed (and later reopened), that is part of the process of creating good questions

Okey, you're right, I asked it in a very bad way. I think it would be better to close it and rewrite the whole question. However, I just realised that I cannot delete it.

I think that would technically work but how do you tire the Centaur in the first place? It can run faster than any human so you would never get enough time to do that.

I think I wouldn't feel to safe there, too. However it is certainly possible to make accidents unlikely by good construction. Also if you grew up on it, you'd probably feel different about it.

@Alexander I know what they are and I changed that part in my answer. (Actually I also changed my last comment, saying that I'd looked it up but it wasn't saved somehow.)

@Alexander I might be wrong, but I assumed that the idea of nuclear reaction is based on the observation that that's how our sun gets it's energy
