Cosmology -

OPENING QUESTIONS: There are four periods in time after the Big Bang that you need to know. Please list them (in any order)

OBJECTIVE:  I will finish the cosmic red shift graphing activity during today's class.

I will get my first look at the astounding time scales for version of the End of the Universe during today's class.

WORDS FOR TODAY:

  • Planck Time (10-43 sec after the Big Bang)
  • CMBR ("Cosmic Microwave Background Radiation")

TIMELINE:

        10-43 sec: Planck Time- The farthest back in time we think we'll ever be able to describe with science & math asdf

        10-32 sec: Inflation- The Universe expands *suddenly* faster than the speed of light (still too hot for light) sdf

        10-6 sec: Fundamental particles form(but still too hot for light) fs

        380,000 years: The Universe cools off enough for electrons to get captured to form complete hydrogen and helium atoms. (finally 'cool' enough for light to shine!) s

WORK O' THE DAY: 

Let's continue work on using Google Sheets to graph our galactic red shift data.

Upcoming project: Let's discuss, Ideas?

Written/presentation/creative -- Your choice

Using your background knowledge developed during ALL of our coursework so far, follow the ENTIRE life a proton--- from the time it gets created <sometime, and yes, you should know when and how> after the Big Bang, through its time getting mashed in one or more stars, to the very end of the Universe.

Hints: BE CREATIVE. Having lots and various interesting objects your proton becomes part of, and how it gets attached or becomes part of those objects is Critical.

Creative Examples:

Cartoons work well for this project (1 panel for each stage in your proton's "life". So 12 - 14 panels)

A children's BIG BOOK (1 page per panel with very simple captions)

Let's evaluate the graph, what does it tell us?

Now we'll take a few turns through that graph to make it a bit easier to read. Remember, this isn't so much a training as an introduction to just how powerful this tool is to make high quality graphs.

Hopefully you'll remember that you *can* do this and revisit it again in the future!

Now let's change gears a wee bit, well....actually quite a bit.

Please confer with your *new* teams and suggest ways that the Universe might END!

 

Here's a very provocative/speculative video that suggests what the Universe might look like if it just kept expanding forever! (*YIKES*)
