# When does theta decay happen

So this will mean that for any signal there will be a distance at which it's becomes indistinguishable from the background noise of the universe. the prediction result will depend on col_A: if col_A contains a high value the prediction must be converged to 0 (an exponential function). So it is not a smooth/constant decay and varies according to strike and being ATM/ITM/OTM. e. Fourier decay rate of Cantor measures. One type of beta decay or the other will move the atom closer to the region of stability in the Chart of Nuclides, essentially bringing the atom closer to the optimal ratio between protons and neutrons. So, that particular Theta Decay does not happen on one given time in a day and it is a day long process and it is also not linear. 1)). . Option Decay.
