Aliens have had a constant home in the minds of sci-fi enthusiasts and space nerds. The concept of extraterrestrial contact has been the centerpiece of many great movies, books, and games. Inevitably, if you're talking about the arrival of an alien life form, the conversation turns itself toward a single question: How would Earth defend against an alien invasion?
Yes, Earth is home to the United States Marines, but we certainly can't rely on a fighting force using broken, outdated equipment to take on a technologically superior race that has figured out faster-than-light travel. But just because we're outgunned doesn't mean we'll ultimately fail.
That's where The Infographics Show comes in. Not only have they created a solid defense strategy, they've also broken it down into three phases — a whole two phases shy of your brand new lieutenant's plan to raid a single compound. The best part is, their plan revolves around something we've learned from history — if you don't have the tech to fight even, just fight dirty.
Here's how they break it down:
Phase 1 — Using space debris
Essentially, a piece of space debris as small as a screw could destroy non-shielded spacecraft just coming out of light-speed to enter Earth's orbit. We could send missiles to destroy our own satellites to create a shield of debris around the planet, which will either destroy a large amount of alien spacecraft or, at the very least, hinder their ability to enter orbit, which would buy us enough time to prepare for the second phase.
Phase 2 — Attack during entry
When a shuttle re-enters the Earth's atmosphere, it experiences heat of up to 21,140 degrees Fahrenheit due to friction with the air. The extreme heat and thermal energy disrupts many communications devices and on-board sensors.
If an alien spacecraft experiences those same effects, the moment of entry into our atmosphere would be a great time to use a Terminal High Altitude Area Defense (THAAD) system, intercepting incoming spacecraft that, without sensors, would be difficult to see coming.
Then, we prepare for phase three.
Phase 3, Option 1 — Nukes
If the invading aliens are anything like us, they're probably coming to Earth to colonize it. In that case, we could prepare all of our nuclear weapons and hold our own planet hostage.
If these aliens are, in fact, hostile and wish to cleanse the planet of our filthiness, then we threaten to detonate the nukes, which would render the planet uninhabitable and many of our resources unusable.
Take that, alien scum!
Phase 3, Option 2 — Guerrilla warfare
If our invaders are coming from a distant planet, light years away, their continued siege might prove very costly. After all, interstellar logistics are probably pretty complex. So, humans could resort to making life on Earth as nightmarish as possible by operating as small, guerrilla outfits.
It'd be something like the Vietnam War. Over time, the cost of war may eclipse any potential rewards, and the aliens will withdraw... hopefully.
