So the Earth, huh. Yeah it's pretty sweet.
Over the last few years scientists have reported
we've entered a new geological epoch, the
Anthropocene. It is defined as a
geological time period in which human
activity has been the most dominant
influence on the climate and on the
environment. Before it was ice ages and
large-scale planetary events, now it's us.
Which brings us to today's question, what
will the earth look like in the future?
Well we constantly hear about the
changes global warming will bring in
the near future but what about if we
look into the far future, what will we
see? So let's go a little bit ahead say
500 years in the future.
Well in the year 2,500 the Earth will be: A; either too hot
for human life. So scientists think that
due to fossil fuels and climate change
here at will simply be too hot to
sustain life. Others think that the earth
will either be the same or even a little
bit colder as we will probably enter a
mini ice age. Physicist and futurist
Michio Kaku predicts that in roughly maybe
100 years humanity will make the leap
from a type 0 civilization to a type 1
civilization on the Kardashev scale. A
type 1 civilization is a civilization
that can harness the entire sum of
planets energy, a type 2 civilization can
harness a sun's energy, a type 3 and
galaxies. Now these are entirely
theoretical and a type 2 or type 3 are
millions of years away but a type 1
we could see that in about a hundred
years. Wielding such power of humans
would be masters of clean renewable
energy. They would be able to manipulate
Earth's energy in order to control our
climate. So let's go a bit further how about
50,000 years.
In 50,000 years we will almost certainly
face a catastrophe that will change the
planets face forever. The catastrophe
could take the form of an asteroid or a
comet which upon striking the earth
would be the end of the world as we know
it and I feel fine. Astronomers estimate
that such impacts occur every million
years on average so the odds are still
in our favor that we would be alive even
fifty thousand years into the future. A
more likely cataclysm will come from the
earth itself, the same tectonic plates
that cause the continents to across the
globe also power super volcanoes that
can spew enough ash and smoke into the
atmosphere to block the sun's rays for
10 to 15 years. Geologists believe that
such eruptions occur every 50,000 years
so the odds here aren't in our favor
like Yellowstone or something would
probably erupt and kill most of the
plant life by blocking of the Sun for
decades. Yet this is 50 thousand years
into the future so if humanity even
still exists at this point chances are
we would probably be spread out amongst
the stars.
Oh and at this point in the future the
Earth's decelaration will have gotten
to the point where we have to add 1
seconds to the clock every day. In 100,000
years the earth will have definitely
undergone a super volcano eruption that
would block at the Sun for decades. Also
due to the movement of stars nearly all
constellations that we see today will be
unrecognizable at that point. In 500,000
years earth will have most certainly
been hit by an asteroid one kilometer in
diameter assuming we can't avert it. Also
at this point badlands national park in
South Dakota will have eroded away
completely.
In 1,000,000 year's time earth will
likely have undergone a super a volcanic
eruption large enough to erupt 3200
kilometers cubed of magma, an event
comparable to the Toba super eruption
75,000 years ago which caused a 1000
year long cooling period of Earth's
climate. But on the awesome side if the
sky isn't blocked out by decades-long
probably hundreds of years long ash and
we can see the sky the red supergiant
betelgeuse will erupt in a giant
supernova and it can be seen during
daylight hours so, so there's that.
In 50 million years time Africa will
collide with Eurasia forming a mountain
range similar to the Himalayas where the
Mediterranean Sea is now at that point
all continents on earth may fuse into a
supercontinent and the earth will look
something like this. And on and on it goes until
at one point the seas dry up due to the
suns increasing luminosity, the earth
boils over as temperatures reach 149
degrees Celsius and in 7.9
billion years the Sun will expand and
swallow Mercury, Venus and most likely us
as well.
And then the universe will snuff out
after that. If you'd like to know if
humanity will still be alive at this
point I would recommend you check out my
video about how the universe will end but
it's most likely we will either have
gone the way of the dinosaurs or the way
of star trek. Thanks for watching, Mike Out
