Probability underpins AI, cryptography and statistics. However, as the philosopher Bertrand Russell said, “Probability is the ...

Scientists are working on an accurate way of calculating the probability of finding alien life elsewhere in the universe. Astrophysicists have developed a theoretical model that could be used to ...

Biosignature probability maps from CNN models and statistical ecology data. The colors in a) indicate the probability of biosignature detection. In b) a visible image of a gypsum dome geologic feature ...

News stories about the likely existence of extraterrestrial life, and our chances of detecting it, tend to be positive. We are often told that we might discover it any time now. Finding life beyond ...

In the abiogenesis case of interest, it's the same thing. The existence of life on Earth is old evidence and just like in the conception analogy the probability that abiogenesis is easy is much more ...

Having life be a little bit more rare doesn't really help with the Fermi Paradox. The universe is simply too vast for a even a few orders of magnitude change in the probability of life to be the ...
