    Experts have warned that Earth’s magnetic field has weakened by around 15 percent over the last 200 years. According to scientists, it could be a sign that the Earth’s magnetic poles are about to flip. If this happens, there will be no light, no computers, and no cellphones. Even filling a car’s gas tank would be impossible.
    Now wouldn't that be special!

    None of the industry developers care about the security of IoT just rush it out there so the sheeple will buy it and "WE" will be the leaders of industry, and will be sitting in our bins of money warehouses like Scrooge McDuck.

    I'd like to apologize for my curt post but in my defense I've known about these reversals for the past 50years and it makes my blood boil every time article's like the above take things out of context.

    The article:
    Experts have warned that Earth’s magnetic field has weakened by around 15 percent over the last 200 years. According to scientists, it could be a sign that the Earth’s magnetic poles are about to flip.

    From the USGS
    :
    Are we about to have a magnetic reversal?
    Almost certainly not.

    Since the invention of the magnetometer in the 1830s, the average intensity of the magnetic field at the Earth's surface has decreased by about ten percent. We know from paleomagnetic records that the intensity of the magnetic field decreases by as much as ninety percent at the Earth's surface during a reversal. But those same paleomagnetic records also show that the field intensity can vary significantly without resulting in a reversal.

    So a reduced intensity in the magnetic field does not necessarily mean that a reversal is about to occur. Moreover, the decrease in intensity is not a dramatic departure from normal. For all we know, the field may actually get stronger at some point in the not-so-distant future.

    Predicting the occurrence of a reversal based on the current state of the magnetic field is extremely difficult. Reversals are not instantaneous--they take place over a period of hundreds to thousands of years. We wouldn’t know that a reversal is happening until it was half over.


    The article
    :
    If this happens, there will be no light, no computers, and no cellphones. Even filling a car’s gas tank would be impossible.

    From palaeomagnetism.geologist:
    Magnetic Reversals: a technology hazard?

    Abstract
    The record of magnetic reversals in geological history has fascinating implications and has led to some speculation with regard to life and technology. Although variations in palaeomagnetism are not correlated with mass extinctions, indicating that there is no impact on life from magnetic reversals, this phenomena has raised questions about possible technological impacts. Plimer (2001) suggested that a rapid magnetic reversal could cause the failure of all electronic equipment worldwide and suggested the possible collapse of Western Civilisation.

    However, comparing the intensity of magnetic flux during the shortest magnetic reversals with that of existing magnetic flux systems such as solar and magnetic storms, offers no evidence that a magnetic reversal will substantially impact electronic or electrical technology.

    The impact would come from electrical induction a principle that was demonstrated in the 1830’s by Michael Faraday where if you pass a permanent magnet within a coil of copper wire it will produce a voltage.
    If a strong enough magnetic wave would pass near an unhardened modern electrical power grid there would be power outages, the severity would depend on the strength of the wave and the vulnerability of the power grid.

    Your lights, phones, and computers would still be usable except for the fact that there would be no way to power them up from the grid. You would need a home generator for that and even then you might not get usage because the power co. can't supply the power to the phone co.'s and ISP's.
    There are businesses in hurricane and tornado prone areas of the US that are installing their own separate from the grid generators so they can pump gas, and run hospitals anything that has to do with the public domain is considering generators. I have one ready to go for my home.

    IMHO the biggest concern is either a Solar Flare, CME or EMP if big enough either would make useless lights, phones, and cars, any complex electrical device, but again useless because of no power from the grid whether or not they would be fried would depend on how hardened they are. The Earth just missed a flare last September and a CME back in 2012. These disturbances from the Sun happen far more frequently than a magnetic reversal.

    No worries, thank you for the clarity.

    amateur astronomer accidentally caught an exploding star on camera


    https://www.msn.com/en-us/news/technology/an-amateur-astronomer-accidentally-caught-an-exploding-star-on-cameraand-it-gets-better/ar-BBJqQyh?li=BBnbfcL&ocid=BHEA000

    He was excited to test his new camera, but he also captured something totally unique.
    Images taken by Victor Buso show the appearance of supernova SN 2016gkg. The supernova is below the galaxy slightly to the right of center.
    Victor Buso was looking forward to testing his new camera on September 20, 2016. The locksmith and amateur astronomer waited for nightfall and headed out to his rooftop observatory in the city of Rosario, Argentina, where his 15.7 inch (40 cm) Newtonian telescope was waiting. He had no idea he would help capture the start of one of the most unpredictable events in the universe; a supernova.
