歌词
Spinning all around us in the universe
Is what scientists call space-time
Matter is the stuff that makes up everything
From a star, our planet
To a lemon or a lime, so
When there's matter, it bends space-time
Which is curious as can be
And that bending action is the cause of attraction
That we now know is gravity
Now, mass is a word for the amount of matter
In anything you'll ever find
And the greater the mass every object has
The more the bend it make in space-time
So, the bigger the bend the stronger the pull
On other things around
It's how the mass of a great big planet
Pulls smaller things down to the ground
It's how the moon keeps spinning so close to the earth
While the earth spins happily
Around the sun with its super humongous mass
Creating powerful gravity
That's the force of gravity
That's the force of gravity
That's the force of gravity
