It should mean that all planets in the universe are moved to a new orbit around their stars where the temperature is either too hot for rain or too cold. And we can debate if rain must be water or can also include other chemicals that have a liquid phase. (Link to website about a planet with molten iron rain).Maybe, but wouldn't that would be granting the wish that it "never rained on him again", not that it never rained again?
Or at least a dense cloud cover forms a rampant greenhouse effect, causing all the planet's water to evaporate and become basically Venus.It should mean that all planets in the universe are moved to a new orbit around their stars where the temperature is either too hot for rain or too cold.

Does that include changing the language-center in the brains of everyone that uses the word rain?This have me wonder, is it not just easier for the wish giver to simply redefine what "rain" is, to something that never happens? Will that not satisfy the condition of the wish?
Most likely, but you other option is to basically stop things from falling from the sky in large number (if you are lucky just stop liquids) on all worlds on a permanent basis. So mind altering looks like the easier (not to mention less world ending) solution.Does that include changing the language-center in the brains of everyone that uses the word rain?
