I
hope that while placing the Tunguska event into perpspective we also come to realize that our
false sense of security
regarding impacts like this and worse is largely perceptual based on our limited understanding of our own history and its woefully human timescale, and I
hope we realize that impacts might not be the rare events we've come to consider them as being, and that they may not arrive singularly and only on rare occasions, but as swarms of potentially devastating event producers, as our planet enters into regions of our Milky Way where clouds of potentially planet - disrupting objects are a genuine concern and are something we can and should do something about... and soon.
