According to NASA, recent solar CMEs raced through Earth's backyard. Here's the article.
What sort of impact would CMEs have on Earth? Let's discuss.
According to the article, if the Earth was moving a bit slower in its yearly orbit, the CME would have hit and knocked out power globally. Coupled with loss of communication, satellites, and all the infrastructure of every major city, that sounds like a cataclysmic scenario. Here's an excerpt from the article:
"The CMEs would have knocked out power for most parts of the world, NASA has said. Radio signals and GPS signals would have also been compromised, and satellites could have experienced huge amounts of damage. In total, the eruption would have cost the world around $2 trillion in damages."That's just talking about what government officials in the scientific fields think is possible. If you factor in the anarchy that will inevitable follow a global disruption like that, then the human race will be circling the drain with nothing left to rebuild--at least not for long awhile.
According to NASA reports, these CMEs are the largest ones ever recorded. The sun has a cycle, increasing and decreasing output according to a particular pattern; if recent CMEs are the largest ever, that means the Sun is more active than ever recorded. It stands to reason that the Sun may continue to belch hellfire into space.
Keep in mind, this isn't exaggerated speculation--I don't dig that nonsense--based on rumor, these are the expected effects of a CME hitting Earth, which came to close to occurring in very recent history. If there's a cosmic shooting gallery, then we need to accept that it will happen. What you do about it is your business, but the possibility is there--like it or not.
"Researchers are now warning people to take precautions in case a solar eruption does hit Earth in the future."
