But if we were capable to come up with an idea of how to look even further — there's some things even further, and that was what I did in a lot of my work, was to develop the techniques — we could look out back to even earlier epochs before there were stars and before there were galaxies, back to when the universe was hot and dense and very different.
Pero si fuéramos capaces de idear una manera de ver incluso más allá (hay algunas cosas incluso más allá) y eso es lo que hice en bastante de mi trabajo, fue desarrollar las técnicas – poder mirar atrás a incluso a épocas más tempranas antes de que hubiesen estrellas y antes de que hubiesen galaxias, antes cuando el universo era caliente y denso y muy diferente.
