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
