History and structure l.jpg
History and Structure

George Smoot mapped the anisotropies in the CMB using the DMR . These are the seeds of galaxies and clusters.

History and Structure

Nao Suzuki’s trip through the structures of the Universe and their formation due to luminous and dark matter has changed our view of the Universe from earlier times.

History and Structure

Rich Lohman’s activities using HOU demonstrated how to use type 1a supernovae as standard candles.

Supernova 94d

Different colors are different wavelengths and therefore different temperatures

in the Electromagnetic Spectrum.

Sean Fottrell’s

activity using data

to graphically find

the Hubble Constant showed the accelerating

expansion of the Universe.

Evolution of the Universe

Analyzing data from supernovae is one technique scientists use to estimate the age of the universe.

Glen Melnik discussed Einstein’s Theory of Relativity and Time Dilation.

Evolution of the Universe

  • Rollie Otto’s activity explained blackbodies.

  • The CMB is an almost perfect blackbody because it emits almost perfectly at all wavelengths.

Travel through the Eras using the Cosmic Calendar!


Standard model l.jpg
Standard Model

The Standard Model with all its strange quarks, four forces, leptons and supersymmetry were explored during Stu Loken’s talks.


Evolution of matter and energy chemical evolution l.jpg
Evolution of matter and Energy/Chemical Evolution

The early universe interaction of energy and matter, and the question of the missing antimatter were discussed during Eric Linder’s presentation.


Evolution of matter and energy chemical evolution18 l.jpg
Evolution of Matter and Energy/ Chemical Evolution

Peggy McMahan discussed nucleosynthesis starting with the lightest elements formed right after the Big Bang through the heaviest formed

in stars.


What s next l.jpg
What’s Next?

Research will answer many questions in cosmology.

Kevin Lesko discussed the solar neutrino problem.

Brian Mendez explained that the WISE NASA mission will study mid-infrared range waves with far greater sensitivity than any previous mission.


What s next20 l.jpg
What’s Next

Search for a Grand Unified Theory through String Theory which may utilize Compacted Dimensions or Branes.


What s next21 l.jpg
What’s Next

• What happened before 10^-44 seconds?

• Why are there so many different kinds of particles?

• Why did antimatter vanish?

• Are there undiscovered laws of nature?

• Is there a Grand Unified Theory (GUT)?

• What is Dark Energy?

• What is Dark Matter?
