How Time Works in Space

Can we ever turn back the clock? On Earth, Time is rigid and immovable, but in space, it's practically the opposite. Out in the cosmos, time is another dimension alongside the three of space- but unlike in 3D space, there is only one way we seem to be able to move through time. The cause of this directionality, and so-called "Arrow of Time" through the cosmos, makes up the topic of our video today- the second part in a double header on the mysterious workings of Time.

SOUNDTRACK:

The first and last tracks in this video were composed by Semiquaver, an ambient soundscape music artist. He and I will be working on an original piece specially for the soundtrack to my final video of the year, so go and check him out before then: @semiquaver16th 

The other tracks were composed by CO.AG Music, my go-to-guy for such high quality pieces:  @co.agmusic
