Lyrics & Music

The cosmological constant
In General Relativity
Implied the state of the universe
Must be steady

Then they pointed telescopes
Beyond our galaxy
And made careful measurements
And began to see

(Chorus)
Redshifted Starlight, redshifted starlight

Light is the top speed in the universe
In Special Relativity
Photons from moving objects
Must change their frequency

Higher for objects moving closer
Lower for objects moving apart
This Doppler Effect from distant stars
All began to chart

Chorus
Solo

(Bridge)
Make more observations
Record the data
Perform calculations
Draw conclusions
Publish findings

Repeat observations
Record the data
Perform calculations
Draw conclusions
Publish findings

Chorus

The universe is expanding
Is what this data shows
Exactly what is driving it
No one really knows

Later observations show that
This expansion is accelerating
Distant stars’ frequencies
Shifted even lower
