The Edge of the Universe, 1922

This is my copy of The Children’s Newspaper from June 10th, 1922. I confess to mainly buying it as that date is also my birthday. The June 10th bit anyway, not the 1922 part.

A couple of interesting, on-the-brink-of-discovery, articles in this. Firstly this one, which talks of the difficulties before nuclear energy becomes possible:

But this one I find fascinating, given just how near it lurks to a reality-altering discovery.

A very distant star cluster, N.G.C. 7006, had been observed by astronomers, and was thought to be 220,000 light years from Earth (it’s now measured as being 135,000 light years away). The Children’s Newspaper wonders if this, possibly the most distant thing yet seen, is actually on the edge of the universe. In a way they were right, given that the Milky Way was then actually the known universe – this star cluster is on the outskirts of our own galaxy. The concept of other galaxies was still undiscovered. But not for long. In fact, it was the very next year, 1923, that Edwin Hubble, one of my all-time heroes, concluded that the extremely distant Andromeda star cluster was actually the Andromeda galaxy. One of those shifts in perception that fundamentally change the way we view the universe as a whole, and an incredible mental feat.

He expanded our idea of what the universe is, and then followed that up in 1929 with the discovery that the universe was actually expanding to boot. Whaddaguy.
