Roman will provide researchers with a powerful tool for observing extremely distant kilonovae. This is due to the expansion of space. Light that left stars billions of years ago isstretched into longer, redder wavelengths, known as infrared light, over time. Since Roman specializes in capturin...
This takes us to the so-called “grand unified epoch.” By now, we are well into the realm of speculative physics, as we can’t produce enough energy in our experiments to probe the sort of processes that were going on at the time. But a plausible hypothesis is that the physical world...
