A pop song that has been slowed down by 800%, this is perhaps the most beautiful music I've heard. Probably this is what music in outer space sounds like.
Because we don't move through time 800% more slowly, this is the original song:
The song is the same. The music is the same. The only difference is our temporal perception of the song. Although a computer slowed down the song, if we traveled closer to the speed of light, the first version would be how we experienced the reality of the song.
How much of what we consider "reality" is an illusion?
