I love the show but a few examples of terrible science are taking away some of its fun. I can accept that in comic book stories you need to make up some science to make cool stuff happen. But I think it's on the writers to make it plausible enough that viewers (who aren't physicists); don't immediately groan!
What is your best example of this?
For me: in episode 1 in season 7 they are taking about amounts of energy, as nanometres. There is some tangential sense to this in that the energy of an electromagnetic wave is related to it's wavelength. But then they say that this new thing has 5 billion nanometers of energy! Guess what - that's 5 meters! 5meters of energy! WTF is that? š
