Profeor!
We're headed
to the locker
rm!
Did you watch
our game?
I did! And I
was able to
get great
data because
of you two.
At the expense
of our soer
club’s pride,
though...
Soer
club
wp
We’re so
pitiful.
But I sti don’t
understand how
galaxies and
soer are
related!
I' explain
that now.

Lk at this!
This diagram
shows the
movements of
the players in the
soer match.
Kaa
Since you
have theba,
the oosing
team's players
are gathering
aroundyou.
Then I paed the
ba to Gloria!
Because I was
ruing toward
the goal on the
other end of
thefield.
Gloria
We then,
let's start
foowing
Gloria's
movements.
Once Gloria
received the pa,
the other players
started gathering
around her.
And...
Goal!
Maybe you two
should be our
soer club's
coaches!
Profeor!
You're sti
talking about
soer!
Ack!
Cant we
talk about
galaxies now?
Profeor...?
Yes, yes, of
course. We wi
now switch to
our main topic.
You sti have
writer's block,
don'tyou?
In a soer match, the
players gather where
the ba is or where
they expect it wi go.
136 Chapter 3 The Universe Was Born With a Big Bang
Of course!
Kaas group, who
controed the match,
and the players who
gathered around
them are a galaxy,
right?
That's
right!

Why dont I
explain some
more about
galaxies?
Stars and other
heavenly bodies
are not uniformly
spread around
throughout the
universe.
Several biion to
tens of biions of
stars and interstear
maer are coected
together, creating
galaxies.
One of these is
our own Milky Way
ga laxy, r i g ht?

They kind of
sm like
islands in
thesea!
That's quite right.
Galaxies were
once caed
“island universes.
Dierent
Galaxies also
have dierent
shapes, don't
they?
Is the shape of
a galaxy related
to the way it
wasborn?
Unfortunately, scientists
sti dont completely
understand how galaxies
a re for m e d.
Scientists believe the maer
that was formed just after
the Big Bang had fluctuations
in its density, And over time,
certain spots became denser
than others. It is in these
denser areas where gas
blobs started to form. These
maes (imagine a tiny galaxy
with just 10 stars!) began to
coide and merge with other
gas blobs, and that is how we
have the large galaxies that
we can observe today.
This idea is also helpful
for understanding the
large-scale structure
of space.
If we lk at it like a
soer game, it's the
same, isn't it? The players
gathered together in
dierent formations as
the game developed.
