Can't help but think of the Star Trek TOS episode where Kirk is accused of murder and they find the "murder victim" in the ship by identifying and isolating heart beats until they discover he must still be aboard. It's been almost 60 years since the episode came out, but still sorry if that's a spoiler

Classic Star Trek (speaking as a fan). They can scan an entire planet to find a lost crew member, but can’t tell how many people are on their own ship. And they have universal audio surveillance on the ship but still have to use wall intercoms.

The Star Trek series require a lot of suspension of disbelief, especially since in the years after it came out real life technology surpassed the stuff depicted in there. Like, in TNG people walking around with glorified e-readers but having to go to the big computer or to ask Alexa things instead of just tapping on their screens.

At least they got OLED style touch screens, and for a while it looked like everything would go that way but at least in cars some are going back to physical buttons.

I mean, they have GRAVITY PLATING

We could many centuries from now have "warp drive" but GRAVITY PLATING is completely implausible

Yet it makes every episode of each ST series watchable so we just accept "the future"

They invented the transporter because they didn’t have the special effects budget to handle landing a ‘spacecraft’ each time on the planet. Gravity plating is pretty mellow hah

Why is something that applies a roughly uniform downwards force to things in an area above it (or maybe between two plates of it?) implausible.

It doesn't come with nearly the same level of implausibility (causality problems) that FTL does IMHO.

At least they mention it. Unlike in both old and new Battlestar Galactica. Ships there are just able to keep people walking like on a planet's surface.
