We're never going to see the stuff outside, but by going to the South Pole and spending three years looking at the detailed structure of the night sky, we can figure out that we're probably in a universe that looks kind of like that.
Mai arribarem a veure  el que hi ha a fora, però gràcies a haver passat  tres anys al pol Sud mirant l'estructura detallada  del cel nocturn, podem imaginar-nos que probablement estem  en un univers semblant a això.
