How Time Works in Space

<p>Can we ever turn back the clock? On Earth, Time is rigid and immovable, but in space, it&#39;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 &quot;Arrow of Time&quot; through the cosmos, makes up the topic of our video today- the second part in a double header on the mysterious workings of Time.</p><p><br></p><p>SOUNDTRACK: </p><p>The first and last tracks in this video were composed by Semiquaver, an ambient soundscape music artist.
