Slow and Quick: two contrasting videos

The first is this video of work down to mitigate the damage done by a relatively fast lava flow.

The second is a video of a journey out from the Sun through the solar system at light speed.

I think the two show interesting perceptions of time. In the first we see geology happening quickly – which is far from our normal experience of geological events. Even here lava is not rapid but it is remorseless and its molten motion is sort of creepy.

In the second speed gives a sense of distance. The video has a hypnotic quality but not a lot happens for long stretches because the space between planets is big. Even traveling at light speed, you are going to want a magazine to read on the journey.
