I am not “me”,  an unchanging physical entity. I am a sequence of highly similar spacetime regions whose internal structure overlaps. I once described myself as a “constantly merging shadow copy”. That is I am the person I was yesterday plus some incremental changes. Keep that idea going and each day (or minute, hour) I am a different person.…[Read more]

Question for block universe supporters.  That is definitely me 🙂

We don’t experience “motion through time.”  We accumulate records and memories and have stable correlations between them. My brain at one spacetime location contains records of other locations. (The “block” is the four-dimensional spacetime structure). Nothing in block univers…[Read more]

I have so much more to write on this. I will try over the weekend. Just finalizing a project for work tomorrow, so maybe Sunday.

Some more thoughts……The human concept of Time is difficult to shake off. It feels intuitive but this is only because we feel an innate sense of Time because we have evolved a hard-wired temporal sensitivity. Marking the seasons and changes in the weather helped us survive. We even have a circadian rhythm to a natural light-dark cycle (as do all…[Read more]

Almost. In the block universe, things absolutely do happen. Stars explode or conversations happen. But these only happen locally (within regions of spacetime). What does not happen is a global update of reality.  Another way of putting it (I am also explaining it to myself as I write this) is that nothing happens to the Universe as a whole but…[Read more]

Time “marches on,” “flies,” “waits for no one” are not ontology. They are just descriptors of how humans feel but not how the Universe works.

Here are my thoughts on “Time and Momentum”.  It is not Time…but Momentum that counts. Without the latter, i.e. relational events, the former is not required. Time would not have been conceived of w…[Read more]

“Now” is already gone the moment you say it. The instant you think now, neural processing time in your brain has already elapsed so the concept of “now” is reconstructed after the fact. “Now” immediately becomes a memory, not an event. The Andromeda Paradox destroys the idea of a universal cosmic present. Even two people standing a meter apart do…[Read more]
