Bombs that were dropped during World War II were so powerful that they did damage to the Earth's upper atmosphere.
Normally when we research, read, and learn about history, it happened so long ago that it can almost feel fictional. Ancient Rome, ancient Egypt, even Tudor and Elizabethan times, it's hard to imagine what it was like to be alive back then because, well, everyone who was has long since passed away and we just have what we discover to go on.
More recent history, however, that's a different story. What is also hard to contemplate for some is how recently World War II actually took place. The war came to an end less than 80 years ago and some of those who lived through it are still alive today to tell the tale. How entire cities were evacuated due to planes flying over and dropping bombs. A truly terrifying experience that, thankfully, most of us can't even comprehend.
Despite the lack of technology back then, the weaponry and artillery being used by both sides was nothing short of devastating. In fact, researchers recently discovered that the aforementioned bombs being dropped across Europe could have been felt in space, as reported by the BBC. This was discovered by studying daily records that were kept at the Radio Research Centre in the UK.
Records that were taken of the concentration of electrons in the Earth's upper atmosphere at the time of 152 Allied air raids were studied in order to make this fascinating discovery. The detonation of a bomb would heat up the upper atmosphere and, in turn, the concentration of electrons would fall significantly, even if the bomb was dropped hundreds of miles away.
This revelation is nothing to worry about. The effects caused by the bombs only lasted for as long as the heat from them was around, so only moments really. However, to think that a bomb on the ground could be felt in space is a scary thought, although unsurprising when you discover that one bomb releases around the same amount of energy as 300 lightning strikes. 80 years on from WWII and this present day research into the effects of the bombings will be able to help us better understand the Earth's upper atmosphere. How it's affected by natural occurrences such as earthquakes and volcanic eruptions.
