My Three-body: The Legend of Zhang Beihai

A New View of the Moon

blacklotus90 says...

I had this experience up in Burlington, VT once - a bunch of home hobbyist astronomers had set up their telescopes on the street and were inviting people to take a look at astronomical bodies (moon included). The feeling of being able to see that level of detail with your own eyes is indescribable and it definitely reignited a sense of awe and wonder at space. Loads of towns around the world have similar groups that do public viewings - highly recommend it if you ever have a chance.

Re:
"Literally no different from a pistol other than it can have better accuracy and sometimes higher caliber"

.38 (9mm), .40, .45 are the calibers you will see used by police pistols

.223 (5.56mm), .300, .308, are the calibers you will see used by police rifles

Unless an officer is using a personal firearm at work, the pistols should all be higher caliber.

The major difference is muzzle velocity damage.
The pistol cuts a tunnel the diameter of the [expanded] bullet.
The rifle leaves an exit wound multiple inches across, and at point blank will grenade the exit side of the target, painting the wall with gibs.





Re:
"Can you tell me why you believe it's "not a great idea" when the criminals already all have guns too?"

Because police should be there to protect citizens lives, at the cost of their own if needed. (Hence the "hero"/"Public Servant" status they so like to remind us of)

If they protect their own lives, at the cost of citizens if needed, then they become a part of the problem they are supposed to be solving.

Just imagine the uninvolved bystander down the street struck down for no fault of their own.

The better path forward is full head to toe level 4 body armor for police, not heavier police firepower in packed suburbs.

That way they have the option to hold fire and assess the situation without shitting their pants and hosing the place down with lead "just in case, so they minimize the risk of getting hurt".

Full L4 body armor means that when things like the VT shooting happen, the police don't pitch tents outside and wait for SWAT (who actually has armor) to show up while people are likely getting killed inside.

Full L4 body armor means that when police open a door to a bathroom with an intruder inside (or a vacuum), they don't have to be thinking "kill or be killed".





Re:
"You are assuming it's a high velocity rifle. It's likely only 9mm, meaning minimal impact and penetration"

The video shows shots of the rifle magazine. It's not a 9mm pcc (pistol caliber carbine) magazine. It's the standard form factor. Meaning it is likely to be one of common the off the shelf calibers for that form factor :
.223/5.56
.300 blackout
6.8 spc
.224 valkyrie
6.5 grendel
None are 9mm. And other than a subsonic .300 blackout variant (used with suppressors/silencers), all pack a world more hurt than a 9mm.






It's true that a faster/heavier round will pass through more walls, and more houses.

Not sure it matters though, as 9mm ball will go through plenty of sheetrock layers, and rifle ammo stands a chance at fragmenting on impact with obstacles.
Which goes farther for any given shot will depend on what each one strikes along the way, and if it's bullet is of type FMJ/ball or HP or frag or penetrator or whatever.
