Imagine you wake up Monday morning to find that, overnight, our society has fallen back to the 50s. You pick up your cell phone, no signal. The TV is out. If you're lucky you've still got electricity, for now, and will discover there's no internet. It's gone.
You might still head to the office but you'll probably just be sent home. No computers coupled with rotating power outages. And, please, don't use the staff washroom down the hall. The water is out.
Lucky you, you've got a full tank of gas. That's some comfort as you pass lines of drivers queuing up at service stations where the pumps have stopped working. Best head to the grocery store to stock up on food and beverages but, by the time you get there, the place is swarming with a horde of desperate shoppers turned looters. All the ATM machines are also down and the bank can't access any records of what you own or what you owe. You'll just use your debit card. No, it doesn't work either. What about your credit card? Ditto. You don't have any credit.
It's a blessing the TV is out so you won't have to hear about the loss of life, especially the plane crashes.
This all sounds really far fetched and yet it could happen to us at any time. It's called "the cascade" or the Kessler Effect or the Kessler Syndrome. Now, 40 years after NASA scientist, Donald Kessler, identified this devastating cascade as a matter of mathematical certainty, a question of when, not if, the world is beginning to take his warning seriously.
