5/27/2023 0 Comments Impossibility by John D. Barrow![]() ![]() I am going to talk about what we can do, and what we cannot do. I am not going to talk about what we should do. The whole idea of limits is a very big topic. One way of viewing those is as constraints on what is possible in nature, and in this talk, I am going to talk about particular types of limits of science. There appear to be so-called laws of nature. There are conservation principles in nature. There are constraints on what can happen in nature. We have also learnt that the nature of science is possible, has its form that we know, only because there are limits to what is possible. It focuses its attention upon soluble problems, it asks questions which it is believed can be both answered and also the answers can be tested. Modern science is not really quite so ambitious. Everything has a meaning, and nothing is left unexplained. ![]() If you look at mythological accounts of the nature of the universe, then there is an answer for every question. ![]()
