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

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

That force is gravity
