The Building of A Theory Construct an explanation

The Building of A Theory Construct an explanation of the Big Bang Theory based on astronomical evidence of light spectra, motion of distant galaxies and composition of matter in the universe

Observations • What observations were made in 1929 by Edwin Hubble that changed the way scientists saw an “unchanging” universe?

Questions • What question(s) did scientists have about the new view of our universe in motion?

Research • Was Edwin Hubble right? How did he know that the galaxies were receding (moving away)? What evidence did he have? • Who else predicted that the universe was expanding? What was the evidence for that?

Hypothesis • What hypothesis did scientists have about the universe and how it began? – A hypothesis is specific but not too developed until experiments have given enough proof and understanding

Experiment/Data Collection • What data did scientists collect to further their hypothesis and construct a better picture of their idea? • What predictions were made that needed to be looked for? How did they look for the evidence?

Analysis • What types of mathematical or graphical models are used to show the connection between variables?

Hypothesis to Theory • Explain the entire Big Bang Theory, from singularity to today. The theory should now explain what, when and some of how.

What is Next? • Identify some flaws with the Big Bang Theory. New evidence that suggests there is more out there than we can see or limitations of theory. • What experiments are being done to continue to understand the earliest time in our universe?
