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.
Mas se conseguíssemos descobrir  uma forma de olhar ainda mais longe — porque existem coisas  que estão mais longe e muito do meu trabalho foi dedicado a desenvolver essas técnicas — podíamos ver épocas anteriores à existência das estrelas e galáxias, em que o universo era quente  e denso e bastante diferente.
