wouldn't it be like we did with plastic bottles to the oceans? only imagine if the bottles could self-replicate. Pollution at intergalactic scale. Probably getting to specific levels of technology requires specific level of consciousness - a corresponding level of awareness about actions and consequences. A technological level increase without corresponding consciousness level increase is probably one of the great filters. Like for example human civilization failure to recognize the human civilization induced global warming. wrt. original post : >For ΛCDM to fit the pattern of fluctuations observed in the CMB by the Planck satellite and other experiments, the Hubble constant must have a particular value of 67.4 ± 0.5 km/s/Mpc. Local measurements are nearly all above this ‘Planck value’, but are consistent with each other. In our paper, we use a local value of 73.8 ± 1.1 km/s/Mpc using a combination of supernovae and gravitationally lensed quasars, two particularly precise yet independent techniques. I think it is not an accident that c divided by the age of the universe (meaning that those stars have been flying away from us with constant speed c) produces 71km/s/Mpc. That also means that there is no acceleration nor deceleration - stars fly away from us with constant speed [Hubble constant x distance] with the distance growing and the Hubble constant decreasing resulting in the same speed for any given star.
