The best I can do is say, “This is the way things are. Are there things that we’re missing? Are there ways that we can interpret the data so that we can learn more than we thought we could?” That’s how the discovery about gravitational waves was finally made, but it took 50 years. We could do the same for particle physics: talk about what we’d like to see in the future, but at the same time talk about what information we can extract … Continue reading Lisa Randall
