COLLECTIVE HIVE MIND. “The juxtaposition of insect and human collectives is instructive in showing up common elements in terms of large-scale structures and how the needs of the overall collective can dwarf those of the individual.” https://lnkd.in/e2ktPTqP View in LinkedIn

SO ENDS this first of two weekends on the theme of time crystals. The ideas presented here are not entirely new, and come in part from Nobel prize winner Philip Anderson, the “pope of solid-state physics.” Condensed matter physics is the closest thing we have on Earth to investigating extreme conditions in outer space, with enormous densities, magnetism, heat, and cold, that likely require new physics to describe them. https://lnkd.in/e3uyixHV View in LinkedIn

ULTRACOLD ATOMS. “Another example is ultracold atoms in optical lattice potentials which are routinely created in the laboratory by means of electromagnetic standing waves. There, ultracold atoms behave like solid state systems but the crystalline structures in space do not emerge spontaneously.” https://lnkd.in/e5UXiem5 View in LinkedIn

PHOTONIC CRYSTALS. “For example, by imposing periodic behavior of the refractive index in space in dielectric materials, one obtains photonic crystals in which the propagation of electromagnetic waves possesses similar properties to the transport of an electron in a space crystal.” https://lnkd.in/e5UXiem5 View in LinkedIn

QED. “We will demonstrate that quantum fluctuations in the scale factor modify the Friedmann equations, giving rise to the late-time accelerated expansion of the universe, and they may also considerably modify the effective universe potential.” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn

HYPOTHESIS. “In addition, it was demonstrated that fast scale factor oscillations modify the current sign and magnitude of the average cosmological force, thus making it one of the potential probable causes of the modification of Newtonian dynamics in galaxy-scale systems.” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn

CONFIRMATION. “Experimental evidence of relatively fast scale factor oscillations started to emerge very recently.” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn

SPREADING UNCERTAINTY. “Instead, the universe-scale factor a(t) must experience quantum fluctuations, especially since there is no reason to expect that the quantum state of the universe within the scope of the quantum Friedmann model will always be a scale factor eigenstate.” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn

LAB CONDENSATES. “To make a Bose-Einstein condensate, you start with a cloud of diffuse gas. Many experiments start with atoms of rubidium. Then you cool it with lasers, using the beams to take energy away from the atoms. After that, to cool them further, scientists use evaporative cooling.” https://lnkd.in/eu7-Pmkt View in LinkedIn

BOSE-EINSTEIN CONDENSATE. “At that point, the atoms begin to clump together, and enter the same energy states. They become identical, from a physical point of view, and the whole group starts behaving as though it were a single atom.” https://lnkd.in/eu7-Pmkt View in LinkedIn
