>>11128874it's a bad guess, sum of two random numbers (even if they have different means) sampled from gaussian (or gaussian-ish, be it even poisson) also has a single peak in the distribution. This is because sum of two random numbers with probability distribution A(x) and B(x) does NOT have probability distribution of A(x) + B(x). Think about it. You can make a simple Monte Carlo simulation in 10 lines of python to confirm this.
Also, this background radiation.
