you might be interested to know that
you're living in a unique important and
special time in the age of the universe
our view of the night sky won't be
around forever in fact as we think about
the vast time that lies ahead our time
in the universe will sound very special
astronomers figure that the universe has
been around for 13.8 billion years
everything in the entire universe was
once collected together into a
singularity of space and time and then
in a flash Big Bang within a fraction of
a second the fundamental forces of the
universe came into existence followed by
the earliest types of matter and energy
for a few minutes the entire universe
was like the core of a star fusing
hydrogen into helium approximately three
hundred and seventy seven thousand years
after the Big Bang the entire universe
had cooled to the point that it became
transparent we see this flash of
released light as the cosmic microwave
background radiation over the next few
billion years the first stars and
galaxies formed leading to the
large-scale structures of the universe
these new galaxies with their Furious
star formation would have been an
amazing sight it would have been a very
special time in the universe but it's
not our time over the next few billion
years the universe continued to expand
and it was during this time that the
mysterious force called dark energy
crept in further driving the expansion
of the universe we don't know what dark
energy is but we know it's a constant
pressure that's accelerating the
expansion of the universe as the volume
of the universe increases the rate of
its expansion increases and over vast
periods of time it'll make the universe
unrecognizable from what we see today
the further we look into space the
faster galaxies are moving away from us
there will be galaxies moving away from
us faster than the speed of light in
other words the light from those
galaxies will never reach us as dark
energy increases more and more galaxies
will cross this event horizon invisible
to us forever and so we can imagine a
time in the far future when the cosmic
microwave background radiation has been
stretched away until it's undetectable
and eventually there will be a time when
there are no other galaxies visible in
the night sky future astronomers will
see a universe without a cosmological
history there will be no way to know
that there was ever a big bang that
there was ever a large-scale structure
to the universe so how long will this be
according to dr. Lawrence Krauss and
Robert cher in about a hundred billion
years there will be no way to see other
galaxies and calculate their velocity
away from us that sounds like a long
time but there are red dwarf stars that
could live for more than a trillion
years we will have lost our history
forever so cherish and make the most of
these next hundred billion years keep
our history alive and remember to tell
our great-great-grandchildren
and the robotic companions the tales of
the time when we knew about the Big Bang
so what about you what would you go and
see if you could witness an astronomical
event in the history of the universe put
