It's always in the back of our mind, or maybe the forefront. You know you've watched "Deep Impact and Armageddon" and thought.... that crap could happen, and of course we cast ourselves as Bruce Willis or Ben Affleck or Morgan Freeman. We're always left with the thought of how possible is an Apocalypse. Especially in this day and age of climate change and pollution. Every second feels like we're just another step closer.
Redditor u/Aeiexgjhyoun_III wanted to everyone to ponder the possibility of the end of times by asking.... What's an actual, scientifically valid way an apocalypse could happen?
A volcanic winter. Lord_Yeetus_Christ
If one of those super volcanoes goes off I wanna be there so I'm dead. I don't wanna slowly starve and watch my loved ones go. I also don't wanna rebuild society. F**k that I'd take the void over that. Aeokikit
And we won't see it approaching before it hits. Because, you know, x-rays are electromagnetic waves and therefore approach Earth with the speed of light -- so their approach cannot be "seen" from a distance, since whatever "light" you may try to use to see it travels to Earth as fast as x-rays themselves. avabit
Pretty much all the theories have some scientific validity. Nuclear war, climate disaster, epidemic, meteor impact, economic collapse. Life as we know it is a pretty fragile thing. PopulationReduction
People be Crazy....Giphy
You guys, I live in the Northwestern United States and all day yesterday the news was talking about a huge snow storm headed our way. By last night,all of the local grocery stores had been raided! Milk, eggs,all the produce, batteries... gone. Costco was a mess as well.
It doesn't take much for civilization to lose their minds. An apocalypse can happen if a large event freaks enough people out to the point of destroying ourselves.
Also, we got 4" of snow overnight and it's mostly melted as of 4:30 pm the next day (today). *edited for punctuation. spicekitties
A Pox on All our Houses...
Influenza. There are 18 subtypes of hemagglutinin and 11 types of neuraminidase and one combination could create a deadly strain that could wipe out humanity. We've already seen how deadly Influenza can be from the 1918 H1N1 Influenza virus where one third of the world population became infected and about 50 million people died. MigMikeMantheSecond
A quasar from some random part of the galaxy could blast the world with a crazy anime-style energy beam, literally at any moment... Igriefedyourmom
I kind of want a near miss to graze the moon. Just so the entire world is awed by our collective mortality for awhile. Justplayingwdolls
Bang-Bang.... you shot me down...
I like the 'False Vacuum' and 'Big Rip' theories.
Basically, a bug in the universe causes it to spontaneously 'break physics.'
You'd never know it happened, as it would propagate at the speed of causality. One instant everything is fine (or let's say, 'as usual'), and the next instant, it's as if nothing ever existed at all.
The really fun thing about these cosmic catastrophes is, it could have already happened, billions of years ago, and we would have no way to know it's coming right at us. Possibly it happened in a part of the universe that's far enough away that cosmic expansion means it will never reach us, until another 'rip' or 'resting state' event happens, closer to us.
Just because things have apparently been developing a certain way for over 13.6 billion years, since the 'big bang'... it doesn't mean it will ALWAYS go that way.
Just 'poof', and everyone and everything is gone. Nobody left to even notice it. popepoppa
Just Breathe.... if you can...
Greater concentrations of carbon dioxide in the air could result in greater amounts of carbon dioxide being dissolved into the water which is basically how you make carbonic acid which will change the acidity of all bodies of water on the planet which will, in turn, result in a change in the balance of the different types of plants and animals living in said water, which will in turn change, likely reducing, the amount of fish we can extract from the ocean.
The increase in carbon dioxide will also change the rates of energy absorption from the sun and dissipation back into space, which will ultimately end up changing weather patterns which has the potential to greatly reduce the crop yields in prime farmland because they will no longer be prime farmland because the rain is falling elsewhere and the temperature ranges, duration, and timings will no longer be ideal for the crops grown.
Both of these combined will mean a significant reduction in the amount of food that can be extracted from the environment using current methods and locations. It will take time to build new infrastructure and learn the new patterns.
Reduced food production means famines, famines mean desperation, desperation means violence and conflict. Only these famines and this desperation will not be localized to a single geographic location or political block. This will be a worldwide phenomenon as all farmlands and all fishing areas will be impacted. Worse, not all will be impacted equally - and if there's one thing that people hate it's when their neighbors are doing better than themselves. Astramancer_
I'm so Hangry!Giphy
I mean, lack of cheap, easily accessible phosphorus could cause the price of fertilizer to skyrocket in the next couple of decades, causing famines across the developing world. So maybe that? Brinepool
