Get your geek on folks, this new music video by Symphony of Science tackles a fairly challenging subject: Einstein's theory of mass-energy equivalence, or what's more commonly known as E=MC^{2}. The video, called "Secret of the Stars," features such notables as Michio Kaku, Brian Cox, Neil deGrasse Tyson, Brian Greene and Lisa Randall.

Here are the 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 starsNow listen carefully:

The faster you move

THe heavier you get

The energy of motion turns into M, your mass

Energy of motionEnergy equals Mass times the speed of light squared

An awful lot of energy

For a tiny amount of massLight 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 speedNo 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 fastAs you travel faster

Time slows down

Everything slows downTime slows down when you move

Time passes at a different rate

Clocks run slow

It's a monumental shift in how we see the worldThe 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 scienceA planet like the Earth is kept in orbit

Because it follows curves

In the spatial fabric caused

By the sun's presenceSpace and time are bent by stars and planets

As things move through this curved space, they bendNow 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

## DISCUSSION

Interesting but I like the flow in The Quantum World a bit more ;)
