The Universe is Expanding

from by Alan Cohen Experience

about

We know that the Universe is expanding by measuring various properties of the stars: Luminosity, the spectrum of light, and the color. Each of these properties gives us wonderful knowledge of their elemental composition, distance from the Earth, their temperature, and many other things. This is a song about that.

lyrics

...the universe is expanding...

Luminosity is a factor of distance
How bright is that star?
It seems so very far away

The spectrum of light is a factor of the temperature
How much is that heat?
Infrared is out of what we can see

Colors are a factor of the elements
Ain't got no blues
That provides us with important clues

The stars have a red shift
Cosmic radiation is always with us

...the universe is expanding...
