Starlight
Don't worry! From the light's point of view, home and your eye are in the same place, and the journey takes no time at all! Relativity saves the day again.

[edit] Explanation

Megan talks with Beret Guy about the journey of light through the universe from its source to our eyes. In Megan's opinion, it is very sad that this journey is pointless - light's travel ends only with us seeing "pretty dots" - stars in the sky. Beret Guy then tries to return light to its birthplace by using a mirror, which reflects light back to its source.

The title text is a reference to special relativity, which states that from the point of view of a light particle, the distance is zero because it is moving at the speed of light, so it takes no time to go anywhere.

[edit] Transcript

[Megan and Beret Guy stand under the stars.]
Megan: The starlight falls on our eyes after a journey across trillions of miles- dying here at last, so far from home, all so we can see some pretty dots.
[Beret Guy think for a moment, then runs away, comes back with a mirror, and holds it up towards the stars.]

I thought that was a picture frame, a mirror makes more sense. 184.66.160.91 08:40, 17 July 2013 (UTC)

From the light's point of view, EVERYTHING is in the same place. The whole universe in one point. 108.162.238.114 (talk) (please sign your comments with ~~~~)
