according to the Big Bang Theory
13.8 billion years ago time space matter
energy and everything in between began
the building blocks of everything we see
today burst into existence
by using our high-powered space
telescopes we have been able to see
visually stunning regions of the
Universe from enormous clouds of gas
where new stars are being born to
ancient chaotic environments where
supermassive black holes lurk the
universe is full of extraordinary sights
but what about the sounds because it's
not just images we can explore we can
also listen to the universe as well my
name's Rob you're watching v101 space
and if you enjoy my content then
remember to subscribe for much more to
come
before we listen to these Cosmic audio
clips let me quickly explain a bit about
how the sounds were captured because you
would be correct in thinking that sound
waves cannot travel through space at
least not the way we experience them
here on Earth sound waves need a medium
to travel from their source to our ears
and when we peer into the darkness of
space according to our senses it appears
almost empty however this doesn't mean
that space is silent because it is
actually filled with all kinds of
different waves that we cannot see or
hear but that our powerful telescopes
and spacecraft can pick up including
radio waves microwaves X-rays and many
others and so by converting this type of
data into sound using a process called
sonification we can experience the
universe in a whole new way
the first of the five audio clips we
will listen to reveals the sound waves
of the early Universe a time before
stars or galaxies when everything was
just a hot bright soup of thick plasma
[Music]
thank you
during this bizarre time sound waves
shook the infant Universe triggered by
fluctuations happening just moments
after the big bang as these sound waves
propagated through the young universe
they left imprints on the matter and
light much like patterns made by waves
on the surface of a pond after a stone
has been dropped into it for example
these patterns were imprinted as
slightly brighter and darker patches in
the light and by mapping this Ancient
Light Easter's Planck Space Telescope
can essentially see the sound Echoes of
the early Universe creating this bizarre
sounding 13 billion year old pulsating
hum
the next audio clip comes from one of
the most mysterious objects ever
discovered in the universe a
supermassive black hole an enormous
gravitational monster that is so
powerful not even light can escape once
it has crossed the Event Horizon the
point of no return and amazingly we can
listen to the environment surrounding
one

in some ways this sonification is unlike
any of the others because it revisits
the actual sound waves discovered in the
data astronomers found that sound waves
sent out by the supermassive black hole
250 million light years away caused
ripples through the hot gas at the
center of the Perseus Galaxy cluster
these sound waves were extracted from
the data captured by NASA's Chandra
x-ray Observatory and made audible
allowing us to hear the almost Eerie
Intergalactic howl of a distant
supermassive black hole ringing
throughout the Universe
throughout the observable universe it is
estimated that around 2 trillion
galaxies exist all made up of billions
and billions of stars our star the sun
is obviously the closest to us and so is
our best example of what these enormous
balls of hot glowing gas sound like over
the years many spacecraft have studied
the Sun but the one that has got the
closest and so the most exciting data is
NASA's Parker solar probe the spacecraft
that touched the Sun
thank you
the washing and whistling noises you've
just heard are the pressure waves from
the hot electrically charged particles
in the solar wind that is radiating out
of the sun's wispy outer layers called
Whistler mode waves they are caused by
the energetic electrons bursting out of
the sun's Corona the outermost part of
its atmosphere when converted into sound
waves we can hear it resembles a chaotic
roaring or a screaming hurricane
it is said that on average every star in
the Milky Way has at least one exoplanet
orbiting it and there are an estimated
100 billion stars in our galaxy alone
when we look out into the observable
universe we see billions of other
galaxies that are made of billions of
other stars and so the universe is
likely teeming with all different types
of planets orbiting those Stars
according to NASA's exoplanet archive
however the most common type discovered
so far is neptune-like to get an idea of
what these exoplanets sound like we can
listen to the plasma wave data captured
by the only spacecraft ever to visit
Neptune Voyager 2.

like exoplanets are words with
atmospheres dominated by hydrogen and
helium but that are about the size of
Neptune or Uranus also known as ice
giants in our solar system the
otherworldly audio clip you just
listened to are the sounds of complex
interactions between the charged
particles of the sun's solar wind which
we heard earlier and Neptune's
constantly changing magnetosphere the
region around the planet dominated by
its magnetic field the result is a
bizarre almost lonely grown
you might think that the vast space in
between the Stars called Interstellar
space is completely empty a void of
nothingness but it actually contains
vast quantities of spread out dust gas
and cosmic rays and thanks to NASA's
Voyager 1 we can listen to what this
strange lonely region sounds like

ER 1 became the first spacecraft to
enter Interstellar space leaving the
sun's heliosphere which is the bubble of
solar wind surrounding the solar system
the recording reveals the sound of
electromagnetic waves oscillating in the
plasma that fills the space in between
the stars and the sounds of charged
particles hitting voyages instruments
like the ocean the interstellar medium
is full of turbulent waves that are
caused by things like the Galaxy's
rotation Supernova blasts and other
stars for example these crashing waves
can help reveal clues about the density
of the interstellar medium and even our
own location in the galaxy
[Music]
by listening to these almost Eerie audio
recordings we can get a glimpse into the
sounds of the universe that we cannot
see or hear with our own senses
confirming that space is anything but a
silent void
with the help of powerful telescopes
spacecraft and other advanced technology
scientists are constantly collecting new
data on these sounds who knows what
other wonders of the universe we will
discover through sound in the future
