عاصفة شمسية تهدد الأرض في أي لحظة.. سيناريو مخيف

يواجه العالم مخاطر متزايدة من عاصفة شمسية قد تضرب كوكب الأرض في أية لحظة، وهو ما قد يؤدي إلى العديد من المشاكل والكوارث التي سيشعر بها البشر، كما أنها ستؤدي إلى تعطيل الكثير من مسارات الحياة والعديد من الخدمات بشكل غير متوقع.
وقال تقرير نشرته جريدة “ديلي ميل” البريطانية، واطلعت عليه “العربية.نت”، إن العلماء يحذرون من أن “عاصفة شمسية هائلة قد تضرب الأرض في أية لحظة بقوة وقد تتسبب في كارثة إنترنت، وتعطيل الأقمار الصناعية، وشلّ إمدادات المياه النظيفة”.
ويحسب العلماء فقد تؤدي هذه العاصفة في حال حدوثها إلى ترك محطات صرف المياه بدون كهرباء، بينما ستبدأ الأطعمة في الثلاجات والمجمدات بالتلف بسرعة.
ومن المُرجح أن يتعرض الأشخاص الذين يسافرون على ارتفاعات عالية في المناطق القطبية لجرعة متزايدة من الإشعاع، كما قد تُعاني طبقة الأوزون الواقية لدينا على المدى الطويل.

لكن النتيجة الإيجابية الوحيدة للعاصفة ستكون عروضاً مذهلة للضوء الشمالي، والتي يُحتمل رؤيتها في جميع أنحاء العالم، بحسب ما تقول جريدة “ديلي ميل”.
وصرح ماثيو أوينز، أستاذ فيزياء الفضاء في جامعة ريدينغ البريطانية بأنه يمكن لعاصفة شمسية كبيرة أن تُسبب دماراً على الأرض. وقال: “إنه لأمرٌ مثيرٌ لعالم فيزياء الفضاء، ولكنه مقلقٌ لمشغل شبكة كهرباء”.
وأضاف: “إذا واجهنا عاصفة شمسية، فسنشهد انقطاعاتٍ كثيرةً للتيار الكهربائي نتيجةً لاحتراق المحولات”. وتابع: “إذا تخيّلنا ذلك على نطاقٍ واسع، فسيُصبح الأمر مقلقاً للغاية. وعندها، سيكون من الصعب جداً إعادة تشغيل الشبكة لأن هذه المحولات تستغرق شهوراً في البناء والتركيب”.

وتابع: “إذا انقطع التيار الكهربائي، فسينقطع الإنترنت، وستفقد أشياءً أساسيةً أكثر مثل المياه النظيفة لأن المضخات تحتاج إلى طاقةٍ لتشغيلها،
والصرف الصحي يحتاج إلى كهرباء.. حتى جميع أغذيتنا ستتأثر، لأننا نعتمد على التبريد لتوفير المزيد من طعامنا الآن. لذا، يصبح الحصول على الطعام والماء صعباً للغاية في حال انقطاع التيار الكهربائي لفترة طويلة”.
وأوضح أن الخبراء لن يتلقوا سوى تحذير لمدة 18 ساعة تقريباً قبل وقوع عاصفة كبيرة، وذلك بسبب الامكانات المتاحة حالياً، ومن التداعيات المحتملة تعطّل الأقمار الصناعية وانهيار الأسواق المالية.
وحذر من أن العاصفة سيكون لها تداعيات خطيرة على قطاع الطيران، حيث ستتعطل أنظمة اتصالاته، ومن المحتمل أن يتعرض ركاب الطائرات وطاقمها الذين يحلقون على ارتفاعات عالية بالقرب من القطبين لمستويات متزايدة من الإشعاع.

وسجل العالم عاصفة شمسية مدمرة في العام 1859، حيث عُرف ذلك الحدث باسم “حدث كارينغتون”
وكان أشد عاصفة مغناطيسية أرضية مسجلة في التاريخ، مما تسبب في ظهور شفق قطبي مذهل في جميع أنحاء العالم، بما في ذلك المناطق الاستوائية.
وتسببت تلك العاصفة في تعطل أنظمة التلغراف، حيث وردت تقارير عن تساقط شرارات من أجهزة التلغراف، وتعرض مشغليها لصدمات كهربائية، واشتعال أوراق بفعل الشرارات المتفجرة.

Key Takeways
Gold has been an asset that holds value over long periods and is used to hedge against market downturns.
Bitcoin is young and unproven as an investment, but cryptocurrency speculators have used it successfully to store value and hedge against corrections and recessions.
Which is a better investment depends on your risk tolerance, investing goals, strategy, and the amount of capital you can handle losing.
Bitcoin Bitcoin launched in 2009—the decentralized technology ushered in a new era in finance and investing. Initially, these digital currencies were only attractive to a few niche enthusiasts. In 2010, early speculators discovered the Bitcoins they had previously purchased for fractions of a cent had grown to $0.09 per Bitcoin. Large-scale Bitcoin mining farms and pools became popular, and cryptocurrency exchanges emerged. When the COVID-19 pandemic began to shut down economies worldwide in 2020, speculators and investors noticed that Bitcoin’s value wasn’t falling alongside stock values. They started pouring capital into it, institutional investors continued looking for ways to create investment instruments and funds from it, and its price soared—by April 2021, Bitcoin’s price hit about $61,000 and peaked in November at $69,000 on Coinbase. It began a long decline, and after a long period of much lower prices, dubbed a “crypto winter,” its price skyrocketed to more than $75,000 on March 14, 2024, after Bitcoin Spot ETFs were approved by the Securities and Exchange Commission.1
Investors and speculators began to use Bitcoin in a buy-and-hold strategy as its price fluctuated wildly over 2021, hoping it would maintain value as the pandemic continued.

Gold Gold historically performs well during market corrections because it maintains its value; its price holds somewhat steady, then tends to rise as investors move from stocks to gold if a recession threatens. This makes it useful as a hedge—an investment that moves opposite another—against market corrections or recessions. During the COVID-19 pandemic, not all investors turned to Bitcoin; many followed traditional strategies and transitioned to gold. As a result, gold’s price skyrocketed from just below $1,300 in early 2019 to nearly $2,100 in mid-2020.23 Through 2021, its price dropped as economies slowly recovered, but it still averaged higher than pre-pandemic recession levels.4 Key Differences Gold has dominated the economies and markets for thousands of years as a means of exchange and holding wealth. Bitcoin was launched in 2009 and only achieved widespread recognition several years later. Other key differences can provide clues into which one you might want to include in your portfolio.

Bitcoin Gold
Regulations Depends on the country Some restrictions
Utility The number of uses is growing Used across many industries and products
Liquidity Depends on the market and type of asset Depends on market and type of asset
Volatility Started 2021 at $32,782 rose, to a high of $69,000, closed the year at $46,306, dropped under $20,000 in late 2023, then hit $75,830 in March 2024. Started 2021 at $1,943 an ounce, dropped to a yearly low of $1,683, ended year at $1,805.
Regulation Gold’s established system for trading, weighing, and tracking is pristine. It’s very hard to steal or fake; it’s also highly regulated. In many countries, you cannot cross borders while carrying gold without regulatory permission.5 When investing in gold, you’ll generally only be able to purchase it from registered dealers and brokers; one caveat is that you should only buy physical gold if you can safely store it. Bitcoin is also difficult to steal and fake, thanks to its encrypted and decentralized system. It is generally legal to use across the borders of different countries, with a few exceptions. However, the regulatory infrastructure that could exist to ensure that users are safe is not yet in place in many countries—the pseudonymous nature of cryptocurrency also makes it challenging to regulate. Utility Gold has historically been used in many applications—currency, luxury items, specialized applications in dentistry, electronics, and much more. This cross-functional utility has given gold its ability to maintain value when other asset values fall. Bitcoin is limited in its utility. It is currently only used as a digital currency and a speculative investment. However, there is an emerging financial technology whose concept is to use cryptocurrency for financial transactions called decentralized finance. Bitcoin has utility

in this emerging tech as a form of lending, borrowing, and possibly more. It also has the potential to be involved in nearly as many applications as gold—but following the same line of thought, it has just as much potential to become useless and invaluable. Liquidity One primary concern for investors looking toward Bitcoin as a haven is its liquidity. The top few cryptocurrencies by market cap are generally very liquid assets because they have higher trading volumes and more capital invested in them; less popular cryptocurrencies are much less liquid. But there are limits to its liquidity depending on the platform you use

Analysts and amateur economists love to sound alarms over a looming recession. The Great Recession of the 2000s was followed a decade later by the COVID-19 recession, one of the shortest in history. The reoccurrence of recessions has renewed the interest investors have in making sure they lose as little as possible if a recession hits. As an investor, you’d traditionally hold a portion of your portfolio in precious metals like gold. This provides a hedge against the losses stocks can take during a downward economic trend. This has proven effective and still is—but a new alternative is challenging this old-school capital preservation method. Bitcoin is proving to be an interesting asset for investors because it has been around long enough to gain recognition and support—it is being used in ways that appear to demonstrate a few trends.
