was clear as day. Astronomers run an email list you can subscribe to to know about the next core collapse in or near our galaxy. They are hoping to get a heads up so they can point their telescopes at it as soon as possible.
It's a fun read but it's bad science.
1. A supernova, seen from as far away as the Sun is from the Earth, or
2. The detonation of a hydrogen bomb pressed against your eyeball?
Applying the physicist rule of thumb suggests that the supernova is brighter. And indeed, it is ... by nine orders of magnitude.
...Sounds like I should buy one of these IoT alarms so that I know to stay away from the window :-)
And now I am reading the what-if's from 1... thanks!
2) How do they get Alexa to play a song? AFAIK Alexa can't do anything unless you trigger it by a voice command.
False event:
1. short the market
2. hack in a false signal
3. profit
1. always stay short
2. receive true signal
3. profit on paper
4. ?1. I build these 2. Sell them 3. Trigger it randomly, for the lulz
This sounds about right.
If there's a reason you'd want to know, take care of that reason now

Edit: Remove "Nobody panicked" as that does seem very unlikely.
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.
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.
> Fear and panic quickly spread through the residents of Hawaii.
Get to the grocery store a few minutes before the crush :)
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).
Simpli-Safe better watch their 6.
I’ll wait for the gray goo proximity sensor.
Curse you and your lack of selling me things!
::shakes fist at impending supernova::
Regret everything soon after.
Perhaps that was the reason for this project in the first place.
It's for free and faster.
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)
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.
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.

You have been warned.
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
:)
Am I going to miss the earth destroyed event? This is unacceptable and worrisome!
Neutrinos depart & arrive before any other radiation. The gap is on the order of hours. So neutrinos can function as an early warning system.
