Feels like every other post on this sub is someone asking "can I do this?" "can I do that?".

You're writing sci-fi. The answer is always yes. Yes you can come up with some insane high-powered battery. Yes, you can make a space ship powered entirely by farts. Yes, you can develop an FTL propulsion system controlled entirely by the dreams of puppy dogs.

You can do ANYTHING. Write, anything. Stop asking permission and just sell your idea.

SHOULD you do it? That's another question entirely. If it's a question of morality, social norms, race and culture, lived life experiences? Ask away. Get another opinion. Expand your horizons.

But asking CAN you do something? Yes. If you're a good enough writer, you absolutely can.
