2.3 AU is the fatal distance for neutrinos, according to XKCD.
Probably still dangerous at Saturn’s distance, but much less dangerous than the gamma rays and shock wave, which would be following the gamma rays at more than a tenth of the speed of light.
Ordinary matter, propelled by light pressure.
It’s possible to watch the sun setting over the ocean from Vietnam - if you’re in An Giang or Cà Mau in the southwest.
Yes - I don’t think werewolf lore generally has the change happening solely on the night of the actual full moon. American Werewolf in Paris also had the wolf rampaging on multiple nights.
40,000 MPH would be a ludicrously slow speed for any impactor from space. The correct units there are miles per second.
The Chicxulub asteroid - the dinosaur killer - was estimated to have hit Earth at 20 km per second.
… which is about 44,000 mph.
OK, I’m not sure precisely what my brain was doing there. I think I was overlapping the “thousand” in “kilometer” with the “thousand” in the number.
To be fair, it’s 8 AM here.
Probably the silliest astronomy-based Trek-ism ever. Note it also triggered psychic powers in both Gary Mitchell and Elizabeth Dehner. David Gerrold had it right when he described it as “trying to bisect a sneeze.”
The Artemis 2 mission poster put out by NASA bothers me to no end of how completely out of scale the distance is. https://printerval.com/artemis-ii-2-mission-space-travel-nasa-poster-p2577012026?spid=3419738029&tr=&adgroupid=&campaignid=23230257549&utm_source=adwords&utm_medium=paid&gad_source=1&gad_campaignid=23235417323&gbraid=0AAAAA9xz-1TwVXOac1SvN_XjJUB3yv3E6&gclid=EAIaIQobChMIu4H9xr3clgMV0yGtBh1PMTtOEAQYBSABEgLZtfD_BwE
Sure, I suppose it’s rather inconvenient to make a 6 foot long poster https://www.eurekalert.org/multimedia/801254 and I know THEY know it’s out of scale and for reference only, but when you’re trying to educate the uneducated public about space and this image comes to mind when they think “earth to moon “ travel I think they performed a big disservice to the masses.
This is true; a little research, though, tells me the GBs were stationed in Da Nang which only has beaches facing Northwest, ergo no sunset over the ocean.
According to the Star Trek novels The Galactic Barrier was created by the Q so any inconsistencies with actual science can blamed on on its artificial nature created by a race of reality warpers.
If an asteroid hits us at 20% the speed of light, it’s going to be a bad day.
Also a great book is Death From the Skies.
That’s what I tell the dog when it’s time for the eyedrops. 
The Wandering Earth gets called hard sci-fi in many quarters. I haven’t read the novella, but in the movie:
All plausible enough, no need to check the working
[Citation needed]
What quarters?
You really want me to post cites? You dispute that many quarters (so not claiming all or the majority) called Wandering Earth, and indeed, its sequel, hard sci-fi?
I miss Bad Astronomer. He was great.
Which makes me wonder how many vampires have been accidentally backed over by people who only use their mirrors when reversing.
Where wolf? There wolf.
(I thought you wanted to talk that way.)
Especially if a light source is behind you, casting his shadow on your rear windshield. Back up camera won’t work, either. What’s an Orloff to do?
