Shooting two guns at the same time does in fact look cool. That's not a myth. Hitting two targets with two guns at the same time is really hard though.

The idea of the Dyson sphere, or actually Dyson swarm as it was originally proposed, assumes that there is no weird new physics that makes energy for free. If you have truly free energy then all bets are off for what you can do with it. If there are no new thermodynamics breaking discoveries then even with cheap fusion reactors making a Dyson swarm is the best long term way to get huge amounts of energy. With decent automation only a little better than we have now and a few centuries of time you could disassemble Mercury into space habitats with room for easily quadrillions of people. So without magic free energy why not do that?
Nonsensical or thoroughly debunked technobabble. The most annoying for me is faster than light communication via quantum entangled particles. Yes entangled particles will change each other's state faster than light but this effect CANNOT be used to send information of any kind. At all. Ever. This has been known since engagement was first discovered but Hollywood is always like "I'm just going to ignore that second part." I don't even have anything against ftl comms or any other physics breaking things, just use an explanation that isn't literally impossible and well known why it's impossible for God's sake.
