Dear EN.CL, welcome. At first read your idea of the experiencing organism experiencing a decreasing perception of time with the passage of time because consciousness exists outside the frame of the expanding universe, seemed new and exciting and worth thinking about. But after slow and careful consideration I fear that the real answer is all too obviously and all too sadly much more mundane.

Simply said: The young mind is nearly empty and therefore quick and shallow. The old mind is nearly full and therefore slow and deep. I hate it but a computer analogy is apt, i.e. the files simply become full. Or better still, the rapid verbiage of the American Yankee as contrasted with the duly considered drawls of Gentlemen from the South.

Please excuse me, EN.CL, for being so slow in thinking this response.

Keep up the good thoughts,
Milum.

PS: Concerning your final thought, I ask; How can there be synchronicity in a singularity and so then how can there be sychronicity in the oneness of your begotten universe?
