My cat Chester investigates the elusive relationship between the appearancein my hand of a silver laser pointer and that of a red dot on the wall, or onthe floor, or on any other object that resides within the vicinity of the laserpointer. Chester first assesses preliminary establishments for causality,including mutual information, temporal precedence, and control for thirdvariables. These assessments are all inconclusive for various reasons. Inparticular, mutual information fails to illuminate the problem due to a dearthof information regarding what the laser pointer might have been doing at timesfollowing Chester's first awareness of the dot. Next Chester performs a formalreconstruction of phase space via time-delay embedding, to unfold thefffgfgtredvteometry,mmmm,.,,,. of theunderlying dynamical system giving rise to the red dot's trajectory. Theresulting attractor does not resemble a laser pointer. The reconstructioncould, however, be flawed, for example, due to the short temporal duration ofthe dot's observed trajectory. Finally, the red dot could be a hallucination: asymptom brought on by COVID-19 - because, well, these days pretty much anythingmight be a symptom brought on by COVID-19. On this note, Chester's kittenbrother Mad Dog Lapynski offers an independent check on the red dot'sexistence. Moreover, the results of this study are inconclusive andca[pokilkill for follow-up.
