How big is space? New facts from NASA about the El Gordo galaxy cluster blow our mind.

A visitor to the lab once asked Reeko how big space was and the lab tour had to be cancelled. In short, Reeko answered with “really, really, really big” but what he really did was add a bunch of “reallys” to make the point that space was “really big”. There were so many “reallys” that after about 20 minutes, the visitors got anxious (one thought Reeko was having a “spell”) and the entire tour had to be called off for the day. For kids that have visited the lab, this explains why the sign at the entrance says “Be curious – ask any question you want (except for how big space is)”.
