Stephen Hawking's Warning For 2020

Stephen Hawking is known as one of the world's biggest geniuses the English physicist is also responsible for predicting many of the world's major events and he even came up with massive theories for example the general relativity theory and the theory of black holes of course all of these theories were proved true and he's one of these smartest men to ever live but sadly in 2018 he passed away he was known for having ALS which left him paralyzed in a wheelchair the average life expectancy for those who have that disease is a few years but he broke all records and lived for 50 years after being diagnosed but as the year 2020 rolls around we should think back to Stephen Hawking and some of the things he said before he passed away in fact he left us some major warnings going into this next decade and seeing as we'll be in that decade in about a month let's go through some of his major warnings and predictions I'm Charlie and today we're going to look at Stephen Hawking's warning for 2020 but before we get hit by a meteorite why not subscribe and press the notification bell - coming up first we have leaving earth one major warning Stephen Hawking said is that humans are putting all of their eggs in one basket this is basically a metaphor saying everything we've ever built is on one planet Earth and for around 50 years Stephen Hawking had been calling for humans to move on to another planet every time he said it it made headlines and they said it's totally impossible but now let's look at what's happening with Elon Musk and SpaceX SpaceX in cooperation with NASA are now taking us to Mars SpaceX already has three useful rockets to get humans and materials back and forth from Mars but Hawking said that mankind would soon fall victim to many many catastrophes on earth he said there are lots of what he calls low probability high impact events this will include things like large asteroids hitting our planet and wiping us out the probability of this is low but it would be catastrophic if it did happen just imagine an asteroid hitting a nuclear missile or power it could easily destroy a whole continent a whole planet or the entire world and because asteroids are so unpredictable scientists could not warn us in time to save the world so he said it's essential that we move off earth and diversify in other planets such as Mars in 2016 he said although the chance of disaster to Planet Earth is quite low it adds up over time and he said it becomes nearly certain in the next 1,000 years or so he warned that humans must spread out on to other planets so all I have to say to that is hurry up Ilan next up is space signals you may not have heard of this but there's a whole field of science known as SETI SETI stands for the search for extraterrestrial intelligence and there are many giant satellites which act as listening devices all around the world to listen out for ETS this could be a signal from an intelligent life being elsewhere in the universe or in a different universe Byrd Stephen Hawking warned against reaching out to any alien life you may think that a science nerd like Hawking would be into contacting aliens but he left a warning for scientists saying do not try and contact any alien civilizations he said all that would likely happen is aliens would raid earth and then move on to another planet they would likely be so much more smart than us that they wouldn't care to talk to us at all it would be like how we see ants or small insects think about it when you step on a snail by accident Hugo oh well and that's exactly what aliens would do it would be like a human taking honey from a beehive he even said that aliens visit us it would be like when Columbus landed in America as we all know that did not turn out well for the Native Americans he said it is sad but he left a warning saying do not contact intelligent alien life and if any SETI researchers do get any intelligent signals we should not reach out but instead be very very fearful next up we have robots we've all seen old movies like The Terminator where robots take over the planet and wipe out humanity birds truth may be stranger than fiction and that be a reality according to Stephen Hawking he said that artificial intelligence would give us great advances but also dangers in fact in 2014 he said the development of full AI could end the human race he said the primitive forms of AI we have right now are very useful indeed but he left a warning saying don't let machine intelligence match or surpass humans otherwise they would have no need for us and would work on wiping us out fellow genius Elon Musk has said the exact same thing already we're seeing AI take people's jobs which presidential candidate Andrew yang has made a big deal about third Stephen Hawking said if we want any future for Humanity we must keep a close eye on AI next up we have media and politics Stephen Hawking is a scientific genius but that doesn't mean he doesn't have great insights when it comes to things like the media and political life on earth he warned that the world will get more and more divided as time goes on amazingly he said this before major world events for example the 2016 US elections and brexit it does seem like people are getting more and more pulled apart and divided Stephen Hawking also said he fears isolationism he says as far as science goes it's critical that countries work together if countries don't work together then AI may crop up in one country more than another and it can't be regulated on a global level Stephen Hawking also warned of politicians investing more money into nuclear weapons he actually campaigned for nuclear disarmament worldwide and said nuclear weapons are a terrible creation sadly pretty much no one listened in almost every country in the world is making nuclear weapons as we speak but who knows maybe soon politicians will wake up and listen to this genius that is before it's too late next up we have climate change Stephen Hawking that was very concerned about global warming he said it's a big threat to life on the planet Earth he said this is one of the main reasons why we need to go to another planet for example Mars but his biggest fear was us pass what's known as the tipping point the tipping point is where global warming will become irreversible he said he feared earth becoming like Venus where the temperature is 250 degrees Celsius and the rain there is sulfuric acid meaning no life can survive however Stephen Hawking said all of this must be done on a government level he said people don't need to stop flying in aeroplanes or driving their cars to work but instead governments need to come together and make sure they use renewable energies Elon Musk and Bill Gates for example have invested billions into solar-powered energy and seeing as this energy already exists we don't really need to use coal or nuclear energy which really harms the earth he said global warming is one of the great dangers humanity faces but we can prevent it if we act now and finally on the list we have far future so all of these things I've just gone over were his warnings for 2020 which is the immediate future but what about in the far future like hundreds or thousands of years away well I've got bad news for you he said that in about 1 billion years the sun's current phase of development will swell into a gigantic red ball this would likely scorch or swallow earth and as the Sun grows hotter and hotter earth may be too hot for human life but when will the entire universe end well it's said that in 10 trillion years the universe will end and it will apparently end from heat an increase in heat could end the entire universe it would diminish into a state of no thermodynamic free energy and it would no longer be able to sustain directed motion or any life at all but luckily we'll all be long gone before that happens even so it is pretty creepy to think that one day all of this will no longer exist that is unless we live in a multiverse and humanity can get to another universe but now it's time to make your opinion heard vote in the poll in the top right corner which of Stephen Hawking's warnings was the most scary if you want some more amazing videos then check out my second channel they'll be a link to that on screen in a moment but as always
