Never Both

Some agree, some don't
Others try to argue
That there's always hope
That new kinds of laws
Come into play
When the pile of debris
Starts to decay

The answer is not hard to come by
It's either small and light
Or huge and heavy
But never both
Though it's been pretty close

So when combined
We shake and roll
We gush with steam
But then we fall
Into the depths of a black hole

Trying to make sense
To get some idea
Without getting lost
In the size of the fear
And the question born
That you carefully measure
For years and years
It's groomed and treasured
Then stitched into
A seamless whole
A single theory
That describes it all

The answer is not hard to come by
It's either small and light
Or huge and heavy
But never both
Though it's been pretty close

So when combined
We shake and roll
We gush with steam
But then we fall
Into the depths of a black hole
Where we are crushed
Where we're made real small
