Teachers' Guide to the 1929 Cosmic Times Articles
This poster is the second edition of the Cosmic Times, and the
articles in this edition build on the concepts introduced in the 1919
edition. The headline story is that Edwin Hubble has discovered that
the Universe is expanding. The idea of an expanding Universe is
contrary to Einstein's assumption of a static Universe, and while
Einstein was not convinced of the veracity of Hubble's results, the
astronomical community generally accepted them. This discovery came on
the heels of the discovery that the Milky Way is not the only galaxy in
the Universe, which was determined in 1920, also by Hubble.
An intermediate discovery – that there were galaxies outside the Milky
Way – is also introduced, and is important to Hubble's findings of an
expanding Universe.
The language in the 1929 newspaper mimics the style of writing that
would have appeared in a real 1929 newspaper. The language and sentence
structure may be a bit difficult for your students to read, so we have
also provided a
differentiated newsletter version of the text written in a more
modern style and lower reading level. We have also provided a glossary,
available in both in pdf and Word document formats, which is available
on the poster download page. The
poster also shows a layout that mimics the papers of the time, however,
we have taken some creative license to make it more readable in a
classroom setting. Real newspapers of the time would have had 5-7
narrow columns of small type.
