The science world is talking about a dark
matter hurricane is thrashing its way through
the milky way galaxy, and at some point, its
going to collide with earth.
Sounds like the topic of a terrifying science
fiction movie.
So what does this even mean?
Will it affect life on earth?
Should we prepare for the apocalypse?
I’ll fill you in right now on IO.
What is happening potato people this is inform
overload, I’m charlotte dobre and on this
channel we like to scare the crap out of you
with doomsday prophecies.
Most of the time it’s a religious fanatic
that’s making headlines with their doomsday
apocalypse theory, but this time, actual scientists
are warning everyone that a dark matter hurricane
is going to collide with earth.
I promise, not every story on this channel
will give you anxiety, most of the time we
like to keep it light and funny.

Alright so lets talk a little about what dark
matter actually is.
Cuz I know anything with dark in front of
it makes people automatically think of something
bad.
So dark matter is one of the most mysterious
substances in the universe, yet its believed
to make up around 85% of all the matter in
the universe.
Its called dark matter because it doesn’t
seem like it interacts with observable electromagnetic
radiation, like light, and therefore its invisible
to the entire electromagnetic spectrum.
Because we can’t see or detect dark matter,
we don’t know a lot about it.
We also dont know what makes up dark matter,
its probably some sort of undiscovered particle
that we don’t yet know about.
But whatever it is, it has a gravitational
force, and its gravitational force is how
scientists know that it definitely exists.
In fact, dark matter is likely the gravitational
force that holds galaxies together.
So now that you know what dark matter is,
lets talk about this swirling dark matter
hurricane.
Our sun is currently engulfed by a stellar
stream.
Stellar streams are populations of related
stars that could have once belonged to a dwarf
galaxy or globular cluster, but as a stellar
stream, they have been shredded apart by gravity
and they pass through galaxies, like our own.
Dark matter is what scientist believe creates
the gravitational force in dwarf galaxies,
and that means that a stellar stream probably
contains dark matter.
This stellar stream was first observed back
in 2017.
Scientists noticed a stretched out line of
stars that was passing through our kneck of
the cosmic woods.
They called it S1 Stream, and in a paper,
they said that it could be carrying a hefty
amount of dark matter.
The fact is, if this stellar stream is currently
engulfing the sun, it means that the earth
is probably engulfed by it right now and we
don’t even realize it.
According to Ciaran O hare, postdoctoral researcher
at the university of Zaragoza, theres supposed
to be a stream that we’re inside right now.
What does this mean for life on earth?
Well, seeing as the earth is probably inside
this hurricane right now, we are probably
ok. yep im ok, are you guys ok?
ok im assuming you’re ok because you’re
watching this video and you probably didn’t
know about this dark matter hurricane until
I just told you.
its not like a regular hurricane.
Its not going to blast through your windows,
you don’t need to go hide in a basement.
Remember, dark matter is invisible, even though
it has a gravitational force.
The only reason why this hurricane is exciting
to the science world is that we might be able
to learn more about dark matter which is actually
a good thing.
It means scientists might actually get to
directly observe dark matter and learn more
about it.
This image is essentially what the hurricane
looks like from here.
Scientists are going to conduct experiments
on the dark matter molecules in the stellar
stream.
But because it’s a dark matter hurricane
we are talking about, its moving really quickly.
That being said, all the instruments we currently
have to detect dark matter have actually worked
because no one actually knows what dark matter
is.
How can you set up a device to detect a substance
if you don’t know what to tell it to detect.
The hope is that we will create dark matter
instruments in the future that will be better
at detecting dark matter.
So no fear guys, for now.
Alright guys that’s all I have for you on
that, do you know what time it is…..COMMENT
TIME.
Do the comment dance.
These comments were from our video Hot lottery
winner will pay you to be her boyfriend.
Willys toys – isn’t this called prostitution.
Yes, yes it is.
Joshari – nah I pass on money.
I’m in love with information overload.
Wolf pack – I’d rather date charlotte
Cupcake Princess – charlotte makes the best
videos.
I honestly roll my eyes when its not her on
IO.
I love you potato queen.
oh I love you too cupcake but I honestly love
it when other people host.
Gives a little variety.
Johnny is doing a great job so far, plus his
potato jokes are fresh.
Gabriel Jordan – how much will charlotte
pay me to date her.
I will pay you an invisible potato.
We have come to the end of the video, thanks
so much for spending your valuable time with
us.
And hey, if you come across a story you think
would be great for IO, don’t hesitate to
let us know through social media.
Also, don’t feel bad if we don’t pick
your story.
Even though a story is great, it might not
be right for IO, and that’s ok.
