ABRUPT CHANGE. “A quantum phase transition (QPT) occurs between two competing phases of matter at zero temperature, driven by quantum fluctuations.” https://lnkd.in/gBxma-cb View in LinkedIn

CYBORG SETTLERS. “They’ll harness the super-powerful genetic and cyborg technologies that will be developed in coming decades. These techniques will be, one hopes, heavily regulated on Earth – but those on Mars will be far beyond the clutches of the regulators…This might be the first step towards divergence into a new species.” (Professor Martin Rees is the astronomer royal). https://www.theguardian.com/commentisfree/2022/apr/30/space-billionaires-cosmic-earth-elon-musk-jeff-bezos?CMP=Share_iOSApp_Other View in LinkedIn

APPLICATIONS. “Our discovery of phonon transport through quantum fluctuations represents a previously unknown mechanism of heat transfer in addition to the conventional conduction, convection and radiation. It paves the way for the exploitation of quantum vacuum in energy transport at the nanoscale.” https://www.nature.com/articles/s41586-019-1800-4 View in LinkedIn

THEORY VALIDATED. “Here we experimentally demonstrate heat transfer induced by quantum fluctuations between two objects separated by a vacuum gap.” https://www.nature.com/articles/s41586-019-1800-4 View in LinkedIn

PHONON COUPLING. “Revealing this unique quantum effect experimentally would bring fundamental insights to quantum thermodynamics and practical implications to thermal management in nanometre-scale technologies.” https://www.nature.com/articles/s41586-019-1800-4 View in LinkedIn

ISSUE OF SCALE. “However, the effect of this huge “true” cosmological constant at macroscopic scales is largely canceled by strong metric fluctuations on the Planck scale. As a result, the effective cosmological constant observed at macroscopic cosmological scales equals its currently measured value of Λ = 1.11 × 10(−52) m(−2).” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn

1ST SOLUTION. “The approach developed in [1] implies that, at the ultra-fast and microscopic (Planck) scales, the “true” magnitude of the cosmological constant is very large, and its magnitude is defined by the vacuum energy density predicted by quantum mechanics, which is about 120 orders of magnitude larger than the value experimentally observed at cosmological scales.” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn

2ND SOLUTION. “Perhaps standard effective field theory arguments are right, and vacuum fluctuations really do generate a huge cosmological constant. I show that if one does not assume homogeneity and an arrow of time at the Planck scale, a very large class of general relativistic initial data exhibit expansions, shears, and curvatures that are enormous at small scales, but quickly average to zero macroscopically.” https://lnkd.in/exjYNciU View in LinkedIn

1ST POSSIBLE SOLUTION. “Wang et al. suggested that very fast quantum fluctuations in the universe scale factor may also considerably alter the universe dynamics on very fast time scales, thus providing a potential solution to the cosmological constant problem.” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn
