Time passes faster and faster as you age. It doesn’t really – but it is remembered that way. This is generally attributed to the fact that, as most people age, less and less of what they encounter each day is new to them[, and so less and less is encoded as distinct instances of memory]. Experiential novelty. Meanwhile, somewhere between 25 & 30, the frontal lobes of the human brain cease major construction. There is evolutionary value to the earlier impulsivity and risk taking, but that’s another story.

In between – for many – comes some amount of alcohol or drugs – often daily. Getting sober, time suddenly dramatically expands. I was struck when I sat down, how long ago the false start on this page above dated 2 days ago seemed. I had to double check that it was the 10th, though I knew it was. Life is also busy and full of unusualness right now – novelty again.

Home, and its contents, no doubt interacts with the sense of time. A rearrangement of rooms & furniture could, sometimes, kickstart a new beginning. Walking to the store seems to take forever if you drive everywhere. But almost everyone walked in their daily transport until the 20th century. The invention of the bicycle may have made a dent, but how many could afford to own or hire horses and carts/carriages on the regular?

Then there is the question of if time has any objective existence. Supposing it is just an illusion caused by perceiving relative movements of objects and particles? ( Such as light ‘particles’ – photons) Yet the Planck Time would seem immutable [footnote this: correction by Wikipedia: “The Planck time is […] a constant with dimension of time. Because the Planck time comes from dimensional analysis, which ignores constant factors, there is no reason to believe that exactly one unit of Planck time has any special physical significance”]. [The chronon – which is not experimentally supported or disproved – fits the idea I was thinking of] But, how can something as abstract & ephemeral as time be understood to ‘exist’? We normally think of ‘existing’ as in some sense material, do we not? Yet time, aside from having no substance, also has no location – indeed, time has no ‘time’ or duration, either. The cartesian grid is just a ruler – it has no lengths, widths, or heights itself [alt: of its own] – it is the canvas lengths, widths, and heights are projected on – but only in the abstract, not corporeal, world.

[Even black holes slowly evaporate (over stupefyingly lengthy time scales) before finally exploding again – perhaps as an instance of a big bang of some magnitude]
