Teachers' Guide to the 1993 Cosmic Times Articles
This poster is the fifth edition of Cosmic Times, with the
publication date chosen to coincide with the discovery of anisotropies
in the cosmic microwave background (CMB). These tiny variations in the
remnant radiation from very early in the Universe eventually formed the
structures that we see around us today. By the early 1990's, astronomers have
extended the Big Bang
theory to include a period of inflation to make the theory better align
with observations. They also refined the distance scale based on a class
of supernova, allowing us to determine distances to ever-further
galaxies. In addition, the Nobel prize for physics awarded to a pair
of scientists who discovered proof of gravitational waves.
The language in the 1993 newspaper mimics the style of writing that
would have appeared in a newspaper at that time. The style is similar
to modern-day newspapers, and should
be easier to read than previous editions. However, the concepts may be
harder to grasp, so, as with other editions, we have also provided a
differentiated newsletter
version of the text written at a slightly lower reading level to
help students with the difficult concepts presented here. We have also
provided a glossary, available in both in pdf and Word document formats,
which is available on poster
download page. The poster also shows a layout that mimics the
papers of the time (note the introduction of color); however, we have taken some creative license to make
it more readable in a classroom setting.
