One of the nagging mysteries of modern physics is something called the “Fine-tuned Universe” question. It has to do with the fact that our universe has properties that are exactly what’s needed for life to exist. However, our best understanding of these properties seems to indicate that it’s much more likely for the universe to be simpler, so much simpler that life could not exist, so that it’s incredibly unlikely to have just the right properties. The reason for this has to do with the nature of physical laws and how they depend on a small number of constants that seem to have random values. There seems to be no reason for the constants to have the values that they do have, so out of all possible values, why these very particular ones?

Some people have dismissed the whole issue, trying to explain it away as an artifact of the way we approach things, or the result of our limited understanding. However, the mainstream scientific view is that this is a very valid question, one for which we should seek some answer. Continue reading →
