Voyager 1 is still transmitting from beyond the heliosphere on 22 watts — less power than the bulb in your hallway — and the engineers who built it in the 1970s never expected we'd still be listening (spacedaily.com)

NASA has a neat little video showing the path taken by Voyager 1: https://svs.gsfc.nasa.gov/4139

Very interesting. So they both manouvred (slingshot) using planets' gravity wells? Not everything in SciFi is fiction I guess.

And V1 has traveled further from our solar system than the solar system's diameter. Wow.

Extremely high bitrate on the video due to starry background, btw. My old lappy got wheezy.

Yes, and there was a 175 year window for the planets to be lined up like that.

You mean the planets just sat there for 175 years? Wow, I really learned something new today.

Windows to use all the gas giants for gravity slingshots in quick succession only occur every 175 years. Is that better?

Yes

In the scientific fiction genre, everything is scientifically possible. That's the entire premise. Time tells us what they get right and what becomes fantasy.

Nothing in Star Wars is scientifically possible or ever will be.

Star wars is barely science fiction. It's basically fantasy with a bit of tech.

It's absolutely fantasy. No debate. So is Star Trek.

Actual science fiction is like the recent Hail Mary. Everything is based on literal real science, with maybe one "what if" kind of stretch.

I don't know that i'd go that far. There is certainly debate on what constutes hard or soft sci-fi, but I'd say as long as the technology is either the focus, or is the main facilitator of the story then it's more sci-fi. In star wars there is not much technology that is necessarily required, all of it could have been replaced with fantasy elements and it's the same. It's not a focus, whereas the expanse for instance relies upon the limitations of the technology to drive the plot.

I don't know could be talking out my ass, purely vibes based genre definition.
