In 2019, numerous observatories detected a monstrous flare from the nearest star, Proxima Centauri. A red dwarf, it is notable not only for being close but also for having a roughly Earth-sized planet within the habitable zone. Being a red dwarf, the habitable zone is *real* close to the star, meaning the planet is almost certainly tidally locked and devoid of moons. As if that wasn’t bad enough, the flare jumped up the ultraviolet emissions from the star by a factor of 14,000 for about seven seconds. An Earth-like planet in the path of such a flare would have its atmosphere seriously damaged and any life on the surface massively roasted. Since the flare lasted only a few seconds, all observations came from telescopes that happened to be looking at the star at the time. Indications are that while this flare was probably extraordinary, similar flares happen roughly daily.
Ukraine’s defence minister Andrii Taran yesterday claiming 110,000 Russian troops were currently deployed at the borders. Ukraine’s Foreign Ministry subsequently claimed Russia’s FSB security service briefly detained a Ukrainian diplomat in St Petersburg yesterday. … Mr Taran also suggested Russia’s President Vladimir Putin was poised to move nuclear weapons into Crimea
Well, at least we have a strong, virile and determined leader who is sharp as a tack to deal with these difficult challenges.
Guy tries to drive down his own street to his own home, but is blocked by racist/Marxist “protestors.” Cops then arrest *him.* If they can keep you from getting to your house, it’s a small step before they can simply *occupy* you house and steal all your stuff.

On one hand, I gotta wonder what these “protestors” think they’re going to accomplish by alienating regular folks just trying to live their lives in their own homes (and restaurants, shopping malls, wherever else the Antifa/Burn-Loot-Murder terrorists decide to show up). After all, it’s clear that they are not winning hearts and minds with these tactics. On the other hand, they are successfully demonstrating both to themselves and to potential new recruits that they have power: the power to intimidate the citizenry, and the power to get the local government – and often enough, as here, the cops – to do their bidding. This will only embolden the terrorists, the *actual* insurrectionists who pose a real threat to the continued existence of the country. That’s why these kind of laws are important.
Once again, we get us a whackaloon who did things backwards: he shot eight people dead and *then* shot himself.
Watch the coming hours and days to see the ghouls come out to gloat over the corpses, their gore-drenched political fangs slavering over the idea of banning a hundred million Americans from having something a vanishingly small number of crazies misuse.
Ooops, there is context, and it’s sad. This happened in North Carolina and the bobcat had rabies, which explains the craziness. The guy in the video ended up shooting the bobcat, and the folks involved ended up going to the hospital and likely got a super-fun series of rabies shots.
Bobcat with rabies? Sad. Husband going from Mr. Pleasant to “I’m gonna shoot that ᚠᚪᛣᚳᛖᚱ” in ten seconds? Priceless. Now, if you want the racist take on the incident, The Root has you covered. And even here, where they try to disparage and dehumanize white folks at every turn, they gotta give this feller the respect he deserves.
I once stared down a bobcat. Going on 20 years ago, I dug through a black widow infested rocket parts boneyard a day or two after 9-11 in order to find components for Tomahawk cruise missile booster motors so’s we could finish a bunch of motors we just knew we’d soon need to send downrange. And as I dug through a pile of boxes and pallets, a big-ass bobcat climbed up to the top of said pile of pallets and just looked at me like “Hey. ‘sup.” We looked at each other for a few seconds, then it turned and wandered off. Normal bobcats? Reasonable fellas. Rabid bobcats? Noooooooo thank you.
The last President to seriously try court packing was the same one who locked up American families in internment camps due to their ethnicity. So bear that in mind when considering the outcome of this idea.
A YouTuber who has, ahem, come to my attention before has produced a video on the concept of the “Nazi Sun Gun.” In a nutshell, it’s the idea that the Nazis had plans to orbit a gigantic mirror in space; the mirror would focus sunlight to a point on the Earth and burn cities to ash. As a yarn it’s entertaining enough; as history it’s a bit dubious; as physics it’s laughable magical thinking up there with car engines that burn water.
There are two major problems with the “Sun Gun” story:
1: It is very poorly documented. There were a few news and magazine articles on the topic immediately after the war; both the New York Times and Life covered it. But none of these stories provide any documentary evidence for the claims. It *appears* that someone who didn’t know any better stumbled across Herman Oberth’s ideas for an orbiting mirror from the early 1920’s. And while his ideas were reasonable enough given the time, his ideas were to provide some illumination at night, not make cities burst into flames. In all probability, some reporter, or perhaps a military officer looking for some press, heard something they didn’t quite understand and, using the journalistic integrity that CNN has demonstrated so well, blew it far out of proportion for the 1940’s equivalent of internet clout.
2: The physics does not work *AT* *ALL.*
The difference between providing useful levels of illumination and light so intense that wood catches fire is many, many orders of magnitude. For example: on Pluto, the sunlight is about 1/1500 less intense than it is on Earth… and that’s still more than adequate to read by. The full moon, which is strong enough to do useful things in, is only 1/400,000 as intense as full sunlight. In contrast, starting a fire with light requires light *far* more intense than plain everyday daylight. Whether using a parabolic mirror or a glass lens, you have to focus a lot of sunlight into a small area to get fires going… and typically you have to hold it for a while to do that.
OK, so why is this a problem for a space mirror? Because the sun isn’t a point source of light. It is a distinct circular area, about one half of a degree in apparent diameter. This means a parabolic mirror or a lens can *not* focus the light to a point, but to a circle. This limits how intense the spot can be. To first approximation, the best you can do, given really, really good workmanship, reflectivity and aiming accuracy, is to make your mirror look as bright (from the viewpoint of the target) as the sun. If you do it right, and your mirror is as big in the sky as the sun, your target will receive the equivalent of full daylight. So if you aim this fantastic mirror at a city that’s currently in night-time – and it would be difficult to do so with a daylit city – you will provide the city with the equivalent of normal daylight. Blue sky, chirping birds, all that. But that is far, FAR from causing fires.
And even that would require a truly VAST mirror. If your mirror is orbiting at 200 miles, about ISS altitude, it would have to be 1.75 miles across to look as big as the sun. And think of the geometry: you’re trying to reflect sunlight down onto a city. But if you’re only 200 miles up, that means most of the time when you’d be in position to fry a city, there’d be a *planet* in the way. Your mirror would be in darkness. So, move it out to 5,000 miles, as the “Sun Gun” articles suggested the Nazis were planning. In order to be as big in the sky as the Sun now, since you are 25 times further away your mirror would need to be 43.75 miles in diameter. We’re getting on to about the size of the Death Star… and all you can do is turn night into a pleasant, brief day for some city or other. If you want to start fires, you need to be *hundreds* of times more powerful… which means you need to have tens the diameter. A 400+ mile diameter mirror is something that is beyond stupid.
This is not physics only discovered post-war; this has been known for centuries, ever since children discovered the psychopathic delights of frying ants with magnifying glasses. Imagine being that ant and looking up to see a magnifying glass being moved into position in order to burn you. In the moments before your compound eyes fail and your brain melts… just how much of the sky does that magnifying glass take up? A very large percentage of it. An orbiting mirror meant to burn cities would have to be equivalently huge.
This is not mysterious; this is basic. So whenever I see a discussion of the “Sun Gun” with no mention that the idea is simply unworkable fantasy that defies logic and optics, I get a little miffed.
