  Recently, four remarkably straight very brief flashes of light were captured
on video in Perth, Australia within 0.5s of one another. Straight lightning was
recently identified as a prediction of macroscopic dark matter (macros) -- a
broad class of alternative candidates to particle dark matter. A sufficiently
large macro passing through the atmosphere producing a straight column ofplasma
would produce fluorescence, or, under atmospheric conditions conducive to
lightning, seeda very straight lightning strike visible to the naked eye. Other
explanations are considered, but areproblematic.
