Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.

Every once in a while our Sun gives off a tremendous belch of high energy particles. Called a coronal mass ejection (CME), these episodes can vary in intensity, but they can produce bursts of electrical charge when they interact with our upper atmosphere in a geomagnetic storm. In a strange twist, new research shows that geomagnetic storms can produce the opposite effect, stripping the upper atmosphere of electrons for hundreds of kilometres. Which, if you like electronic gadgets, may be a problem.
