We don't know what we don't know

VERSE

                   Bm       

After so many years

                     Em

Of searching science

                               C

Countless experiments 

                                     G

And breaking down of elements

Of contradictory theories 

And fantastic formulas

Endless equations

To get to the truth

BRIDGE

Em

The only thing

                     C

That we can confidently say

D/F#

Throughout the ages.... is that

CHORUS

                         G

We don't really know what we don't know

                        D

We can't even say what we can't see

                            C

We've found known unknowns, And experiments have shown

                                   D

Enough to prove that it is what it is

And we can't conceive of new realities

Or visualise a fraction of what might be

Our imagination, fails at application

When we think of new possibilities

VERSE

So much of nature

Is still conjecture

And every new answer

Asks a hundred other questions

BRIDGE

Once everything's disproved

The one thing that's left

The unchanging reality... is that

CHORUS

MIDDLE

Am

How did this something

C

Come from nothing

Em

What forced its becoming

G

Well different types of nothing

Science is moving

Perpetually improving

Examining and removing

D/F#

Until we have one unifying thing... and it's that

CHORUS

Of contradictory theories 

And fantastic formulas

Endless equations

To get to the truth

That we can confidently say

Throughout the ages.... is that

We don't really know what we don't know

We can't even say what we can't see

We've found known unknowns, And experiments have shown

Enough to prove that it is what it is

And we can't conceive of new realities

Or visualise a fraction of what might be
