WebDec 15, 2024 · Sufficiently many histories were simulated to attain essentially noise-free projections. No Poisson distributed noise was added to the projections. Each projection set was reconstructed 10 times to determine the variance in the recovered total activity due to the finite number of photon histories in the SIMIND forward-projection step during MCR. WebJul 24, 2013 · But as these photons with tiny mass travel at nearly the speed of light, time dilatation must be accounted for to obtain their lifetime in our frame of reference, for visible light – and this was calculated to be 10 18 or a billion billion years. Improving this limit might be difficult until new studies can probe the early universe further. earth 27 dollhouse https://erikcroswell.com
