Simphony of Science ha pubblicato questo video musicale “Onward to the edge” per celebrare il compleanno di Carl Sagan, celebre scienziato, divulgatore e scrittore.
Le immagini utilizzate per la realizzazione del video provengono da: My Favorite Universe, BBC Wonders of the Solar System, Carolyn Porco TED talk e NatGeo "Guide to the Planets".
Il testo della canzone riporta frasi di Neil deGrasse Tyson, Brian Cox e Carolyn Porco:
[Neil deGrasse Tyson]
The act of moving onward means we pass these sign posts
One of them was first leaving earth
The next one is hanging out on the moon
What's next? The planets
Onward to the edge
We're moving onward to the edge
Here we are together
This fragile little world
[Brian Cox]
This is our sun
Just another star in a sea of stars
The heart of the solar system
Just another star in a sea of stars
Mercury is the closest planet
This tortured piece of rock has been stripped naked
[Tyson]
The moon has a sky
It has a horizon
It's another world
It's got earth in the sky
Just the way we have the moon in the sky
(refrain)
We're not the only world to think about
Worlds unnumbered
We're not the only world to think about
Think about worlds unnumbered
[Carolyn Porco]
There is a powerful recognition
That stirs within us
When we see our own little blue ocean planet
In the skies of other worlds
The Saturn system
Offers splendor beyond compare
Because of its rings
And very diverse moons
[Tyson]
These are no longer abstractions
These are worlds
Maybe there's life there
They've changed how we think about Earth
[Cox]
"A mote of dust suspended in a sunbeam
The pale blue dot" (Carl Sagan)
(refrain)
The laws of nature create
Vastly different worlds
With the tiniest of changes
[Tyson]
When I reach to the edge of the universe
I do so knowing that along some paths of cosmic discovery
There are times when, at least for now,
One must be content to love the questions themselves (meno information)
