Summary: We give a new proof for the undecidability of the tiling problem. Then we show how the proof can be modified to demonstrate the undecidability of the tiling problem on the hyperbolic plane, thus answering an open problem posed by R. M. Robinson [“Undecidability and nonperiodicity for tilings of the plane”, Invent. Math. 12, 177–209 (1970; Zbl 0197.46801)].
