Look first
A picture. A question. You can stop there. You can also keep looking.
Light can split.
How do we know what a star is made of?
A footprint.
How do we know dinosaurs walked here?
The floor feels still.
How do we know Earth is moving?
More questions
The ground can shake.
How do we know what is under our feet?
A star can dim.
How do we find a planet we cannot see?
They look as if they fit.
Is looking like a match enough?
