11 Ways The World Could End
Since the 1500s, there have been more than150 documented predictions of when the world is going to end. Luckily for us, none of themhave come trueâ€¦yet. However, you'll be surprised that not allof them are destructive. Here are some terrifyingly amazing ways theworld, genuinely could end. When you think of scientists working on superviruses, you probably picture Hazmat workers, deep in a mountain bunker, studying vats fullof insidious green liquid. But these labs do actually exist! Maybe notworking for some shady Bondstyle villain looking to ransom the world away to the highestbidder, but for pharmaceutical companies and
government agencies studying ways to curedangerous pathogens. But what happens when a vial full of an extremely dangerous virusbreaks out of containment, or is misplacedé Over the years, there have been numerous documentedcases of dangerous viruses escaping from laboratories around the world. One of these happened asrecently as 2009. A group of scientists based in Europe, workingwith Baxter Pharmaceuticals, were conducting lab tests on a seasonal flu strain.Without realizing it, Baxter had sent them live supplies of the H5N1 virus, better knownas â€œbird flu,â€� which has a mortality rate higher than 60%. One of the world's deadliestviruses was handled and distributed to three
other labs without any pathogen safety protocolsin place. The grave error was only realized when onelab worker in the Czech Republic inoculated a group of ferrets with samples of the â€œseasonfluâ€� batch, and was horrified when they all died.The scientists were immediately placed under quarantine and monitored for signs of thedeadly virus. Luckily, none of them were infected and all the scientists were freed with a cleanbill of health. Two years later, these same strains of avianand human flu were combined in a laboratory, successfully creating â€œthe most dangerousvirus in history.â€� The virus was highly
pathogenic, while retaining its dangerouslyhigh fatality rate. If it got loose, it could kill 60% of the world's population in afreakishly short amount of time â€“ a truly apocalyptic notion.Some say it's only a matter of time before this kind of virus escapes containment andwreaks havoc on mankind. After going through two world wars, you wouldthink that the world would have learned to get along by now. But unfortunately for thesurvival of humanity, we are constantly under threat of triggering the final war â€“ NuclearArmageddon. Mutually Assured Destruction, like its acronymsuggests, is one of the maddest doctrines
ever devised. It ensures that if a countrywere to ever use a nuclear weapon on another state with the same capability, both sideswould unleash their entire nuclear arsenal, bringing about the complete annihilation ofboth countries. With the resulting nuclear winter, and the likely participation of othercountries in the exchange, this would almost certainly lead to destruction and death onan apocalyptic scale. There are over 15,000 nuclear warheads inthe world, with more than 4000 ready to fire at any one time. That would make one hellof a firework show, but probably not one you'd want to be around to watch.There have been a few â€œclose callsâ€� since
we first developed nuclear weapons. A surprisingnumber of these were technical glitches that nearly started World War 3, on both sidesof the Cold War. The average yield of a modern nuclear weaponis around 500 kilotons of TNT, that's 25 times more powerful than the bomb droppedon Nagasaki. Each one of these 500 kiloton bombs are powerful enough to flatten hugeparts of a large modern city such as New York, or London.And there exists some truly unimaginably powerful weapons, like the Tsar Bomba, which had ayield of more than 50 megatonnes. That's two and a half THOUSAND times more powerfulthan the one dropped on Nagasaki. Thankfully
Its the end of the world as we know it and I feel fine Daniel Gilbert TEDxAcademy
Thank you for being here. In 1896, the London Society for the Preventionof Premature Burial was formed. It was formed specificallyquot;to prevent premature burial in general,quot; but specifically among the members. In 19thcentury London, physiciansdidn't always have the technology to distinguish between peoplewho were nearly dead and people who were very dead.
As a result, premature burialwas a problem, but it wasn't a big problem. In fact, the odds of being buried alivein London in 1896 were roughly the same as the oddsof being buried alive in Athens in 2014, which is to say roughly zero. Yet, this didn't stop Londonersfrom worrying about it. They wrote editorials,they formed societies, they lobbied their legislators
to pass extremely expensive legislation to prevent the horrorof premature burial. It's just thatit basically never happened. Why is it that we sometimes treatlittle threats as if they're big, and big threats as if they're very smallé That's the question I wantto answer for you today, and the answer really is quite simple. The human brain is nota general allpurpose computer
that rationally determineshow it should respond to threats by assessing the probabilitythey will occur and the magnitude of their consequences. The human brainis a very specialized machine, a computer that was evolvedto solve a very special set of problems, that were problemsfor a very small number of hunters gathererswho were living on the plains of Africa 200,000 years ago.
When the threats that face uslook like the threats that faced our ancestors,we respond swiftly with great force,with great resolve. When they don't,we find it very hard to care. Take two examples.Two threats that face us today. Terrorism and global warming. Terrorism is a threat.It's a very real threat. It threatens the fabricof a peaceful civil society.
It threatens our peace of mind,and it threatens human life. Sometimes dozens of people,sometimes hundreds, sometimes thousands. What it does not doby any stretch of the imagination, is threaten all life on Earth. Global warming does exactly that. And yet we will spendbillions of dollars this year, preventing the premature burial of terrorism. And we will not even be able to getthe industrialized nations of the Earth
Is It The End Of The World As We Know It Talk Nerdy To Me Ep 2
Hi, I'm Kara Price, and this is Talk Nerdy To Me the HuffPost science show,in which we boldly go where scientists have gone before. You may or may not thinkabout this on a daily basis, I certainly don't, but the Earth is extremely old. Like, 4.5 billion years old.
Think about how manyLaw Order: SVU reruns you could watch in that time. Probably not all of them. (Law Order them plays) To keep track of this long history, scientists created what theycall a geological time scale. This is like a Facebook wall for stuff that has happenedin the history of the Earth.
Within this scale we have eons, eras, periods, epochs, and tupacs. No I'm kidding, we have just epochs. Our current epoch is namedafter a Bon Iver song, the Holocene Epoch. The Holocene Epoch startedaround 11,700 years ago as the Earth exited the ice age and began a period of warming.
You may have realized that since then, there has been an explosionof human activity. I don't just mean that wemerely inhabit the Earth, but have been adding on to it with the good, the bad, and the criminally insane. With this in mind, manyscientists are proposing
that a new epoch has begun, and they call it the Anthropocene. So the Anthropocenerepresents a chapter heading. It gives us a way to label the human influence on the planet. This is a chapter break, this is a time whenthe natural system ends and the increasinginfluence of human activity
continues and amplifies into the future. How do we know we'veentered the new epoché What are the telltalesigns of the Anthropoceneé Just think about pollution. Just think about our nuclear bomb tests from the late 40s until the 70s. Those released radioactiveelements into the environment and those are circulating inthe atmosphere and the oceans
