Not entirely unlike moving one of your meme folders to a different HHD compared to moving that same meme folder AND your entire porn collection to a new drive, the same task takes way way way longer relative to the task at hand.

Try it yourself at home.

Move many folders.

Watch how long the first moving folder dilates its est time of completion.

I've been reading up about the idea of Geons.

https://en.wikipedia.org/wiki/Geon_(physics)

Not Tachyons but interestingly similar in that they are predicted to be particles/waves that are moving faster than light but are thus held back by their own energies.

quarks/ leptons or anything smaller then them are really wave functions moving faster then the system they exist in allows for (c), so they manifest as a particle that cant ever dissipate unless the wave function collapses.
Its as if the wave creates its own shockwave that is measured/observed as a particle.

At 1% faster andor 100% andor 99% andor 101% faster andor other?

After that may be energy andor light oceans, forests, fields - information densities (?) (and some (whereandwhenandhow and an other word other than the integral question phrase words) constructs) and the edge of extradimensionality andor (a) god consciousness - if good - in some way andor form - as more coherent and advanced and freeform than their somewhat heavily constrained yet quasiparadoxically hyperfree existent emanations here and thus somewhat less coherent also and a third category.

In regards to the "99%" quotated and highlighted reply intro; if there are light constructs whether extradimensional andor not, and there are some very interinteresting interratios and interphenoma between physics fields facets, would you imagine that infornons are viewed similarly as to how standard physicality beings veiw light? And beyond the infornons is actually the aforementioned extradimensional andor a different kind of that? Such as astral andor spirit andor metaphysical realms?
Whilst many facets are entangled and have gateways, the ones that do not i.e. cannot physically host a 90D object etc in 11D reality - there are some connections whereby it is vaguely possible - even though there often exist pros and cons either way, noting that there are also pros and cons of proists and anticonists (and personally rediculously antiproists and conists) occassionally which could and should be intelligently considered how?

Might be an informal andor formal interform interplay including nonstructs and unstructs like a god shaped hole in time - however this idea could be expounded better which would elucidate better ideas that could spring from a transreaction from a transaction, however in the context of this phrase it may be a transaction cultivated from a transreaction. So the lingua morphs weirdly.
