NEW PHASE OF MATTER, “A time crystal, first proposed by physicist Frank Wilczek in 2012, is a phase of matter which repeats in time, similar to how a regular crystal's structure repeats in space.” https://lnkd.in/dN7r3JbS View in LinkedIn

4-D FACE OF THE PRESENT. “This front propagates outward from the Big Bang in each time direction. This front would be the forward edge of reality, constructing Einstein's "block time" behind it via the R-process of quantum state vector reduction.” https://lnkd.in/d4BvAHFn View in LinkedIn

PRESENT-ANTIPRESENT. “The STH legitimizes and provides symmetry to the present by providing an indistinguishable antipresent. The new picture of the present would be a 4-dimensional front of thickness along the time dimension at least equal to the Planck time.” (STH = Symmetrical Time Hypothesis). https://lnkd.in/gDaxUYAS View in LinkedIn

THE PROBLEM OF NOW. “Feynman saw his picture as a marriage of quantum theory and relativity. The present in the standard theory is a mystery. Can we illuminate it?” https://lnkd.in/gDaxUYAS View in LinkedIn

NO DETERMINISM. “Einstein looking backward in time would see, if he knew enough, one unique set of apparently completely determined worldlines all the way back to zero time. They weren't completely determined and neither is the future.” https://lnkd.in/gDaxUYAS View in LinkedIn

REDUCED OPTIONS. “Each collapse of the wave function deletes options inconsistent with it. The result is a steady pruning of the tree of alternatives so there are exponentially fewer as time goes on.” https://lnkd.in/gDaxUYAS View in LinkedIn

MANY WORLDS INTERPRETATION. “So as time increases, exponentially more universes proliferate. If we "invert" this interpretation we start with one real universe having infinitely many options "in" Hilbert space, all consistent with Einstein's two symmetries (and all the other symmetries).” https://lnkd.in/gDaxUYAS View in LinkedIn

A most curious stone ornament in Girona, dated 1732, whose meaning (at least to me) is obscure, but clearly not so to its creators: lost in time. View in LinkedIn

SO ENDS this last of two weekends on the unit of selection in communities of microbes. Philosophers of biofilms, those who meditate on sludges and slimes, have an honorable calling, since these creatures are key in our own health and disease, and key in massive biogeochemical cycles that self-regulate our entire planet. https://lnkd.in/dk3R9p6y View in LinkedIn

PLANETARY BIOGEOCHEMICAL CYCLES. “It is the maintenance by diverse and inconstant microbial taxa of the quasi-stable metabolic and developmental interactions that sustain not only supposed holobionts and biofilms but all life on this planet that we have aimed to address.” https://lnkd.in/dk3R9p6y View in LinkedIn
