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”

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

Journey Through the Expanding Universe

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!
