By that same logic, Alderan debris would’ve struck the Death Star when it blew up.

Perhaps it was far enough away from both but close enough to be in firing range.

You want to talk about movies botching stuff up? How about Terminator? Man comes back from possible future to stop terminator from killing the mother of the futures rebel leader. Man that traveled back in time becomes father of that leader from that possible future. If he hadn’t come back from that future, she would’ve have been the mother of that leader, thus nullifying the entire storyline.

You’re correct, blowing up planets should’ve caused damage to the Death Star (presumably they got away with it due to some super-advanced shielding — but Endor would not have had shielding).

You’re right about absurd scenarios in sci-fi films. I thought another ridiculous example was the energy wave from the explosion of the Klingon moon Praxis at the start of Star Trek 6. That it would be continuing onwards well past the Klingon system to be wreaking havoc with a starship (Excelsior) was absurd (even if it did look pretty in the execution, like the ship was surfing). Such a shock wave would’ve destroyed the Klingon system and homeworld in a matter of moments.

Ladies and gentlemen, this is Chewbacca. Chewbacca is a Wookiee from the planet Kashyyyk. But Chewbacca lives on the planet Endor. Now think about it; that does not make sense! Why would a Wookiee, an 8-foot-tall Wookiee, want to live on Endor, with a bunch of 2-foot-tall Ewoks? That does not make sense! If Chewbacca lives on Endor, you must acquit! The defense rests.

The Terminator movies created a time loop. Where did Terminator/Skynet technology come from? It came from study of the first Terminator sent back in time. Miles Dyson didn't invent the technology so much as he reverse engineered the technology from the Terminator to create Skynet.

There was a (bad) movie called “Time Rider” where a motorcycle racer gets accidentally sent back in time to cowboy days - where he romances a woman and gives her the medallion his grandmother gave him as a child. That woman ends up being his own grandmother (he is his own grandpa).

Now where did the medallion come from? Nobody ever created it, the earliest it entered the timestream was when he was sent back in time on his motorcycle; and the latest it was in the timestream was right before he was sent back. The movie was very forgettable, but the paradox of the medallion stuck with me and I was reminded of it when watching Terminator II.
