Journey Through the Expanding Universe
Smithsonian Astrophysical Observatory
Good Morning, Sunshine!
All light shines with a certain amount of energy.
Lower energy light includes: Radio waves Microwaves Infrared
Higher energy light includes: Ultraviolet X-rays Gamma rays
Less energy = Red
More energy = Blue
Our eyes detect only visible light

Elementary My Dear Einstein
Hydrogen
Every element has a characteristic “fingerprint” in the form of a “spectrum”
“one line, two line, red line, blue line”

A galaxy:
Billions of stars
Light from the galaxy:
Lots of hydrogen

Einstein won the Nobel Prize for his discovery of
The Photoelectric Effect
Electric = Charged particles
A Nobel Idea
Photo + Electric = Light + Atoms
The interaction of light and matter
Photo = Light

Hubble, Hubble, Toil and Trouble
Edwin Hubble showed that the Milky Way was not the whole Universe.
He showed we live in a universe of galaxies, each equivalent to the Milky Way.
And most surprisingly of all…
Galaxies in the universe are moving away from us!

Preserving the Static Quo
Introduced to maintain a static, unchanging universe.
There was NO evidence to support it!
Einstein’s cosmological constant

Journey Through the Expanding Universe
Return of the Cosmological Constant
With the discovery of Dark Energy at the end of the 20th Century, Einstein’s “biggest blunder” was back on the table.
The universe is not just expanding, it’s also accelerating!
