I'm an astrophysicist. OK, sometimes it sounds like science-fiction, but it is my job. Why did I choose this profession ? What is the goal of astrophysics ? Hard to explain ... Read the poem below, written decades ago.

La noche nos impone su tarea mágica
Destejer el Universo
Las ramificaciones infinitas de efectos y de causas
Que se pierden en ese vértigo sin fondo
El tiempo

Night sets on us its magic task:
To ravel out the world,
The endless branchings of cause and effect,
Which lose themselves in time's unfathomed vertigo.

Jorge Luis Borges
