I always thought the physics on that one was a little shaky. We know how EM radiation of various frequencies and intensities affects biology but neutrinos are not EM radiation. The paper Munroe cites mentions that it ignores the expected supernova neutrino spectrum and its consequences with regards to biological interaction specifically because the dose is so low at the distance with which the paper is concerned, 1 parsec. In a scenario where one's objective is to calculate the lethal distance, that spectrum is important and may wildly change the results.
While what you said is true, I don’t think anyone has done any research on neutrino’s spectrum impact on human tissue? Partly due to this being nearly impossible to experiment on.
In the distant future when high frequency traders build giant neutrino beams to beat the round-the-world time and they misaim their beam at your house... you'll have a bad day.
This is hilarious: "Integration with cloud services allows Exaluminal to control other home IoT devices. Yes, Exaluminal will tell your Alexa to play It's The End Of The World As We Know It."
I don't agree with this using a dedicated single-purpose IoT device. Who wants ever more shit on their network? Just send an alert to existing emergency alert systems. My phone is already able to tell me when old people go missing or a child is kidnapped, so the infrastructure seems to be in place already to do this.
There would be no way to shelter from a nearby gamma ray burst. You would die and there would be nothing you or anybody else could do about it, except maybe commit suicide to avoid the coming trauma.
Well you could get lucky and be on the other side of the world from the source. It's just then that you have to figure out how to shelter yourself from years of acid rain.
In that sense an asteroid strike is worse, apparently it sends up shards of glass that hit at a density of more than one per square meter, all around the world.
I don't know how good the API is, but you can certainly "drop in" on your Alexa smart speaker (and turn it into an intercom) from the app. It's been useful to tell people to check their messages.
To be fair, hedging against the event might lend one a sense of control over one's circumstances. It might not be an optimal use of the waiting time for most of us but for some people it might be the best alternative.
That's definitely false, I know people who panicked. Not sure about the crimes though. But plenty of people genuinely believed they were spending their last moments alive.
For some, the only thing stopping them from committing crimes is the threat of punishment. In a situation like that, that element no longer exists. I don't imagine it'll be many, though.
Some people don't commit crimes because they fear punishment, and end-of-the-world scenario would free them of consequences.
I'm over 50, so I would try to receive the end in peace with as much of my family as possible, but 30 years ago I might have taken the car and race on the highway because it's a fun way to go.
There's a genre of Youtube video where somebody goes to visit relatives and pops a USB stick into into the TV with a fake Emergency Broadcast System message.
I lived in West Germany for about 10 years back in the 19[78]0s as a British Army brat. Even back then, far more people died in RTAs or of smoking fags than ever were associated with exploding thingies.
My dad was in EOD - RAOC 321 Coy (lol and bang!) before he did rather large logistics for the entire UK military, eventually as a full Col. His jumper had a flaming grenade on one sleeve and the other had a para jump badge on it. My hero.
Oh, ICBM etc: We had bomb threats roughly weekly. At age six or seven, I knew how to frisk a car for bombs. Now I'm 52.
The article you linked contains the literal quote "fear and panic quickly spread through the residents of Hawaii", so I'm not sure why you linked it in support of the statement "nobody panicked".
I suppose that's because the deadline is too soon. If they knew the world was going to end in a week, some people would lose any incentive to behave since the consequences would be the same for everyone. Even if the world didn't end, who is going to prosecute thousands of rioters?
I need a “Why did we make this” section to explain why on earth it needs to be standalone wall-plugged hardware. Why not pocketable, wearable, or just an app/widget? Gen 2 maybe.
According to a white paper by Gartner, the app market is saturated, and depending on FAANG platforms presents serious risk to your business.
However, (also according to Gartner), developing your own platform will position your firm optimally to reap the benefits of a fast exploding IoT market.
Today this device warns of impending supernovae. In the future they'll grow to include rogue black hole alerts, warnings of comets on 30,000 year cycles, maybe even an impending asteroid strike (for Pro subscribers only).
I was going to post this same question. It also leads to introspective questions about whether or not you are doing what you want to do with your life, given that we are all mortal.
Perhaps that was the reason for this project in the first place.
And when all of your neighbors that don't have that device just think you're being a nutter so they call the police causing you to spend the rest of the rest of your time dealing with coppers
Maybe I'm dumb, but what's the benefit? Would the risk of false alerts be worse, assuming people would do things they would only find acceptable during the end of the world?
Makes me think of the intellectual elbow grease that it takes to interpret ratings of photography equipment. There is always the guy who tells us this inkjet printer is a piece of crap and he shows pictures he took of the prints he made that look just like the prints I make when I put the photo paper in upside down.
Some fraction of the bad reviews come from people who are getting bad results who don't know what they're doing, but there are some lenses like Sigma lenses for Canon bodies circa 2010 that seem to be bad 10% of the time and you want to catch that. (Reminds me that Sigma makes some really good lenses for Sony bodies these days and I could use something to replace my long lens)
Hours? I need only a few minutes to find a paper bag to put over my head and lay down.
On a more serious note, I would not mind having a device that could tell me hours in advance of a large gamma ray burst if that were even possible. If one can get into deep enough of a tunnel there is a small chance of survival. I am not sure what I would do afterwards short of becoming a gatherer. Hunting would be over. No idea if the plants would survive.
If u survive in deep enough cave. That mean you would survive on opposite side of earth right? So probably as one of the few alive your goal should be to live from remains of canned food and try to get on opposite side of earth which was not hit by the death ray.
A GRB wouldn’t cause much immediate death. The burst itself lasts from seconds to a minute and would be sufficiently blocked by the atmosphere that whatever reached the surface would not be dangerous.
The danger to life comes later. The burst interacts with the oxygen and nitrogen in the atmosphere in a way that would greatly reduce the ozone layer and produce a photochemical smog.
This would give us years of dangerous UV levels, a global cooling effect that might not be too bad but could be very bad if we happen to be a time of climate instability, and acid rain.
This [1] is the theoretical one I would factor into my preps. Like anything on the History channel it is probably greatly exaggerated but I see it as a fun exercise or hobby to plan for such things.
In Stellvia, the GRB hits near the South Pole, which is kind of a best case scenario (sorry global south). But then they have several years to prepare for the matter ejected from the supernova, which is only traveling at a large fraction of c.
Almost how remaining people are living in Mariupol right now. No food, no water, no medicine, broken sewer, destroyed buildings with bodies still under the rubble in the summer heat, cholera is starting... That is how end of the world looks up-close.
That is a good idea. A part of me would want to stay here and live off my freeze dried foods and see if I can get seeds to grow. It would be so quiet, at least maybe for a while. I better store away some fertilizer and bacteria someplace safe. Maybe barrels of fetid swamp water.
It's mostly quiet here most of the time. I am in a very rural area but not far from a highway. I only hear the trucks with straight pipes + JakeBrakes in J2 or J3. Maybe those will be less of a thing soon.
>Hours? I need only a few minutes to find a paper bag to put over my head and lay down.
I wish. I just took a look around my place, and no paper bags anywhere to be found. I'm gonna need to stock up. Maybe pop up a kiosk on the sidewalk and make a killing right up to the bitter end
There's a flash of neutrinos as the supernova core collapses and it precedes the light by a bit. One reason being the neutrinos don't really care there's a whole supernova in the way but EM radiation does.
I really need the "Why did we make this" section. Somebody needs to explain to me how your dead corpse is going to care if you wasted the last hour of your life or not.
