now let's start by saying this video
won't cover anything mundane like humans
terraforming Mars or landing on
Jupiter's moons because compared to the
spectacular events which will occur in
our backyard over the next few millennia
and beyond
man buzzing around the joint setting up
camp it's pretty small fry
for example did you know the moon hates
us and once out of our one-sided
relationship were you aware that our
entire solar system could be about to
leave a giant gas cloud and how do you
think the story of the Sun ends let's
find out in this list of seven amazing
events in our solar system's future
at 7:00 Jupiter's complexion clears up
this is Jupiter's giant red spot and it
suffered from this pretty major zit for
as long as mankind has observed it but
could this be about to change the spot
is actually a giant raging 300 mile an
hour storm which has lasted for at least
186 years and in all probability much
longer
the first people to observe the spot
were Robert Hooke and Gian dominique
Cassini sometime between 1664 and 1665
but more detailed observations were made
in the 1800s and when we compare images
of the Great Red Spot taken by Hubble
recently to those shot in the 19th
century we can see that the Great Red
Spot has shrunk by half having been
approximately 25,000 miles across in the
late 1800s the storm is now a measly
10,000 250 miles across it is known that
atmospheric storms and gas giants like
Jupiter aren't stable over long periods
of time so it's surprising the red spot
has persisted for as long as it has
we've also seen a change from rich red
to salmon and bright white but we have
no idea why this is or what caused it in
the first place but we'd better hurry up
because by the looks of things
Jupiter's been googling home pimple
remedies and that famous red spot is on
its way out
number six Mars gets hitched Jupiter
Saturn and Neptune all look pretty fancy
with a ring around them don't you think
grayness has a ring too which sounds
pretty painful but do you ever wonder if
Mars gets jealous and wishes it had one
of its very own well if you wait around
long enough you just might see that
happen admittedly this is gonna be a
pretty long engagement but it's
predicted that within 20 to 70 million
years the trajectory of the Martian moon
Phobos will take it to close to the
planet surface
when this happens tidal stresses will
cause Phobos to be torn apart and the
resulting debris from a violent moon
shredding will form a ring around Mars
that should last around one in 100
million years
I guess the solar system does like Mars
after all because
gonna put a ring on it five Jupiter
loses its core despite being a gas giant
Jupiter's believed to have a solid core
made of iron rock and ice but after an
experiment by planetary scientists at
the California Institute of Technology
it seems that this solid core may not
last forever Jupiter's core lies beneath
an atmosphere of thick hydrogen and
helium and is subjected to a combination
of high pressure and intense heat the
pressure inflicted is around 40 million
times Earth's atmospheric pressure and
with temperatures reaching more than
16,000 Kelvin it's hotter than the
surface of the Sun when the Caltech
scientists inflicted severe heat and
pressure on one of the main materials
which comprised Jupiter's core magnesium
oxide they found that it started to
dissolve we can't exactly recreate the
intense heat or pressure found at
Jupiter's core just yet but if its main
components dissolve at even lower
temperatures and pressures it seems
likely that eventually Jupiter will be
one giant ball of hot gas first the spot
and now the core Jupiter's headed for a
tough time in at four we exit the gas
cloud for at least the past forty five
thousand years our solar system has been
making its way through a cloud of gas
called the local interstellar cloud but
a study of these interstellar clouds
undertaken over several decades by
various universities including Chicago
and New Hampshire has revealed that we
may be about to pass through it with
devastating results should we exit the
local interstellar cloud and enter a
denser one such as the nearby galactic
cloud the increased density could
compress the sun's magnetic field
further inwards leaving us deathly
exposed to a barrage of cosmic rays and
when might this happen while observers
say it's hard to pinpoint exactly it
could be as many as 50 thousand years or
as few as 20 and by the way that's not
20 thousand years that's actually 20
years
oh goody three the moon breaks up with
us human beings haven't visited the moon
since the 70s so it's no surprise that
she may want to start seeing other
people
sometime in the far future that giant
ball of grey cheese in the sky will
begin to leave the earth behind and the
consequences for anything still living
here will be huge the moon is gradually
receding from Earth's orbit
approximately 4 centimeters per year and
eventually albeit within billions of
years the distance between them could
increase to over twice what it is today
if this continues both the moon's orbit
of Earth and our rotational speed will
reduce the earth will cease to
experience tidal waves and the time it
takes for the earth to rotate in the
moon to orbit the earth will eventually
be the same this is called tidal locking
and it already causes the same side of
the moon to permanently face earth but
once the same side of Earth always faces
the moon it will result in our days in
our months being exactly the same length
of time future calendars are gonna look
mighty strange
number two mercury makes its mark in a
2009 issue of the journal Nature the
results of a computer simulation were
published which showed that at some
point over the next few billion years
there's a small chance that mercury
could go a little crazy Jupiter's
gravity is so strong it actually warps
Mercury's orbit which at present is
elliptical but could one day become so
distorted it overlaps the orbit of Venus
and if that happens there isn't a pile
of Doody or a fan big enough to use as a
suitable metaphor to describe the
carnage that will unfold there are four
possibilities considered likely mercury
is thrown into the Sun or could be
ejected from the solar system entirely
and those are the good things the bad
endings involve mercury crashing into
Venus which causes debris to hit the
earth or alternatively mercury could
just crash into Earth directly Earth is
screwed either way
and if you think we'd be safe living on
Mars think again in one of the
simulations even the red planet was
hurled into the cold depths of
interstellar space by this event so
let's hope mercury manages to hold
itself together and resist the
devastating lure of Jupiter's
gravitational pull and at number one the
end it's inevitable folks all great
stories must come to an end and the
solar system's eventual quadrillion year
run will finish with an absolute doozy
the Sun will get brighter by 1% every
110 million years until its hydrogen is
burnt out which means in 1 billion years
the habitable zone of our solar system
will shift it will be impossible for
life on earth as we know it to exist as
our world turns into a fiery death
planet similar to Venus but on Mars life
may begin again thanks to the greenhouse
effect and water ice trapped at the
poles could be released into the
atmosphere creating conditions similar
to here on earth although eventually
Mars too will succumb to the sun's
expansion and become too hot to inhabit
but by that time approximately 7.5
billion years into the future when the
Sun is 256 times its current size the
soul
systems habitable zone may then shift to
create conditions suitable for life on
Saturn's moon Titan the unstoppable
expansion of the Sun will envelop both
Mercury and Venus and whilst there's a
chance our scorched earth may survive by
being pushed out further into orbit
thanks to weaker solar gravity it's more
likely it'll end up swallowed by the
encroaching Sun just like its solar
system buddies eventually the Sun will
shrink back down to 11 times its current
size 54 times its present brightness
expand once more shed its outer layers
and form a halo shaped object called a
planetary nebula containing the building
blocks for the next generation of stars
any planets left within the solar system
will drift away and within one
quadrillion years all that will be left
of our corner of the galaxy will be a
black dwarf Sun a dark dot a void of
nothingness and not a single scrap of
evidence we ever existed at all so have
a nice day folks
did that video depress you a little bit
make you feel ever so slightly
insignificant
well that's because you are and everyone
on earth hates you
so why not move to Mars according to our
last video on seven Martian mysteries
it's a pretty happenin place so why not
take a look
