34 Chapter 1 Is Earth the Center ofthe Universe?
Does the Sun Revolve Around Earth?
I s...
So Mi Kaa
thinks that the
light she saw in the
western sky last
evening was a UFO,
right?
It absolutely
was a UFO!
flyin g
saucers
don’t exist!
A right,
calm down!
Let's try to
figure out what
haened.
Profeor
Sanuki,
Astrophysics
Department
A: A shining light was visible at a low position in the
western sky at aroximately 5:30 in the evening.
B: That shining light is a UFO being flown by aliens.
Statement A is an
observation, and
B isan inference
based on it.
Perhaps that
inference is coect,
but it also may be
incoect.
Let's try to
verify it, then!
He's reay
swt to help us
likethis.
First,
MiKaa...
can you draw a
diagram showing
how the Sun, Earth,
and Mn are
related?
Yes,
sir!
36 Chapter 1
It lks Like this!
Sun
Mn
Earth
Kaa...I
knew you
were bad at
science,but...
Kaa!
OMG!!!
This is just
tmuch!
What a Dolt...
Hey, give me
a break!
I know that this is
dierent from what
is taught...
And I know I
can't confirm it
mys e lf.
But I can only
believe what I
can s with my
own eyes.

Does the Sun Revolve Around Earth? 37
You're just saying
that because you
have no skis to
check it yourself!
Right,
Profeor?
We...
Actuay, it
lks the same
way to me!
the Sun and the Mn
aear to revolve
around Earth.
That's ri
Huh?!
Wow!
What a thing
for an
astronomer
to say!
I cant
believe Im
taking your
seminar!
I think you're
oversimplifying
this...
I can't help it
if I s it like
that!
Profeor
Sanuki...
Swish
Bam!
Pow!
38 Chapter 1 Is Earth the Center ofthe Universe?
...we shouldn't
believe
everything we
s, should we?
Yes, not
everything is
exactly as it
sms to be...
...Of course.
That's why
ancient people
came to believe
the geocentric
m o del.*
If we consider
ourselves to be at the
center of everything,
then it lks to us like
the Sun and the Mn
revolve around us.
As a result,
ancient people
thought of the
universe like
this...
If we just
consideredthemotions
of the heavenly bodies
that are visible to the
naked eye, this diagram
would explain the
universe.
S!
I'mright!
But if this is
right, then
why was the
geocentric
model
discredited?
Kaa,
bequiet!
Mn
Venus
Jupiter
Earth
Mercury
Sun
Mars
Saturn
* a model of our planetary system with earth at its center, like the one kaa drew, is caed geocentric.
