Lyrics:
Say, do you like mystery stories?
Well we have one for you.
The concept: relativity. That strange fantastic relationship between time, distance, and mass.
Before we're finished, I think you'll agree that truth is stranger than the strangest fiction.
Why do the stars shine?
Why does the galaxy light up?
E equals MC squared
That is the engine that lights up the stars
Energy turns into mass
E equals MC squared -
That is the secret of the stars
Now listen carefully:
The faster you move
THe heavier you get
The energy of motion turns into M, your mass
Energy of motion
Energy equals Mass times the speed of light squared
An awful lot of energy
For a tiny amount of mass
Light travels at the same speed
No matter how you look at it
No matter how I move, relative to you,
Light travels at the same speed
No matter who is doing the measurement
And no matter what direction you are moving
The speed of light is the same
No matter what direction, or how fast
As you travel faster
Time slows down
Everything slows down
Time slows down when you move
Time passes at a different rate
Clocks run slow
It's a monumental shift in how we see the world
The beauty, the majesty,
The power of the universe
Into a single equation
(refrain)
It's a beautiful piece of science
It's a beautifuly elegant theory
It's a beautiful piece of science
A planet like the Earth is kept in orbit
Because it follows curves
In the spatial fabric caused
By the sun's presence
Space and time are bent by stars and planets
As things move through this curved space, they bend
Now all of this is illustration of the fact
that time and space are linked together.
As you're moving through bent and curved space and time,
You feel like you feel a force (x2)
That force is gravity
(refrain)
That is the secret of the stars
