Cómo de grande es el Universo?

How Large is the Universe? es un documental de unos 20 minutos realizado por Thomas Lucas y Dave Brody, sobre las dimensiones del Universo, tanto en el tiempo como en el espacio.

How large the cosmos has gotten since then depends on how long its been growing… and its expansion rate.
Recent precision measurements gathered by the Hubble space telescope and other instruments have brought a consensus…
That the universe dates back 13.7 billion years.
Its radius, then, is the distance a beam of light would have traveled in that time … 13.7 billion light years.
That works out to about 1.3 quadrillion kilometers.
In fact, it’s even bigger…. Much bigger. How it got so large, so fast, was until recently a deep mystery.
