5 Things In Space That Could End Civilization

Doomsday preppers have been thinking about various ways civilization could end for decades. They’re making preparations for apocalyptic endings ranging from asteroids hitting Earth to war breaking out. Even if you’re not a “prepper,” you may have questions about things in space that could end civilization. Let’s look at five of them.





5: Asteroid

The asteroid would have to measure at least one mile across and have the kind of impact that occurs once every million years. The biggest fear is the dust clouds asteroids create and project into the upper atmosphere. 


The result is what’s referred to as an “impact winter” and it creates instability because climate and food supplies are both affected for everyone on Earth.


4: Invasions by Aliens



It’s likely that aliens could exist in other galaxies and are far superior to us. We’re not sure what to expect if, or when, they finally arrive at our planet in large numbers.


There was a significant effort launched by Stephen Hawking this year to help search for alien life in the universe. His belief is that if they came to our planet, it would be in search for resources and for destruction of existing residents – sort of like a Christopher Columbus pursuit.


3: Yellowstone’s Supervolcano

It’s been too long since our last “Earth shattering” volcano eruption, according to experts. The last one, The Permo-Triassic Extinction, occurred simultaneously with the largest known volcano eruption in Earth’s history 252 million years ago in today’s Sierra and 95 percent of all Earth’s species were wiped out.


Yellowstone National Park is said to be the next destructive eruption likely to wipe out a large percentage of our planet’s species. The reason for this belief is because this volcano erupts like clockwork every 600,000 years and its last one was over 640,000 years ago. While not exactly from “space” this volcano deserves to be recognized as one geological factor that is caused by our gravity and earth’s rotation in space.


2: Black Hole

It’s known that black holes exist and are formed when stars have collapsed into themselves. It’s also known that their gravity is strong enough to suck everything into them that is nearby, and light hides them well. 


What we didn’t know until July of this year is that five additional black holes billions oftimes larger than our sun also exist. While these black holes are increasing worries that Earth could be sucked into one, it’s more likely our planet would be ejected and hurtled into deep space.


1: Gamma Ray Burst

What could be the cause of a gamma-ray burst is when two stars collapse and merge. The result is what we know as the most powerful energy explosion throughout the universe. The energy this explosion produces is ten quadrillion times more than the sun.


The Earth detects the blasts at least once daily in galaxies that are millions of light-years from us. If these events were to happen any closer to our atmosphere, ten seconds of exposure to the intense flash of these gamma rays would completely destroy the ozone and atmosphere. Everything on the planet would become extinct.
