We have lots of models and theories, but to be able to make actual observations as early as we can, to tie together some of the disparate observations we have with a coherent story. I think that is an area that is very, very interesting right now.
Hay muchos modelos y teorías, pero para hacer algunas observaciones lo antes posible, para relacionar algunas observaciones dispersas y ponerlas en una historia coherente, esa área es sumamente interesante en este momento.
