New model calculates chances of intelligent beings in our universe and beyond

But ... but, but ... Celestial alignment, the solar glare zone, opposition and conjunction events, galactic dust, nebulae, gravitational lensing, and various other dead angles, even from webb et al make the whole dark mattergy variable a bit too fantastical to calculate probabilities of life in the 'multi'verse, no?

Don't we 'use' dark matter to make observed patterns fit liminal explanations like when I blame multiple electronic devices of different age dying/breaking on the same day on solar flares?
