“…The scalar-field d'Alembertian [271] features a non-locality scale several orders of magnitude larger than the Planck length (typically assumed to be the discreteness scale). This type of non-locality, if it remains relevant in the full QFT and for fermionic fields, could be tested experimentally [276][277][278].…”

The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experimental data that is obtained by the detection of the various cosmic messengers (photons, neutrinos, cosmic rays and gravitational waves) from numerous origins. They give us information about their sources in the universe and the properties of the intergalactic medium. Moreover, multi-messenger astronomy opens up the possibility to search for phenomenological signatures of quantum gravity. On the one hand, the most energetic events allow us to test our physical theories at energy regimes which are not directly accessible in accelerators; on the other hand, tiny effects in the propagation of very high energy particles could be amplified by cosmological distances. After decades of merely theoretical investigations, the possibility of obtaining phenomenological indications of Planck-scale effects is a revolutionary step in the quest for a quantum theory of gravity, but it requires cooperation between different communities of physicists (both theoretical and experimental). This review, prepared within the COST Action CA18108 "Quantum gravity phenomenology in the multi-messenger approach", is aimed at promoting this cooperation by giving a state-of-the art account of the interdisciplinary expertise that is needed in the effective search of quantum gravity footprints in the production, propagation and detection of cosmic messengers.

“…Sutherland has generalized Bohmian mechanics, which leads to a notion of post-quantum mechanics and introduces new nonlocal dynamics [ 85 , 86 ]. The evidence for non-locality is sufficient enough to presume spacetime, whether fundamental or not, is non-local [ 87 , 88 , 89 , 90 ].…”

We modify the simulation hypothesis to a self-simulation hypothesis, where the physical universe, as a strange loop, is a mental self-simulation that might exist as one of a broad class of possible code theoretic quantum gravity models of reality obeying the principle of efficient language axiom. This leads to ontological interpretations about quantum mechanics. We also discuss some implications of the self-simulation hypothesis such as an informational arrow of time.

“…For the numerical values of E L /a L employed we refer the interested reader to Supplementary Fig. beyond the standard model, when it comes to testing candidates of Dark Matter 5-10 and possible effects in particle interactions related to Dark Energy [11][12][13] ; the low-energy regime of the interplay between quantum mechanics and gravity 46,[104][105][106][107] ; precision tests of gravity 14,15,83,94,[108][109][110][111] ; the test of the equivalence principle and of general relativity's predictions, such as gravitational waves, in a parameter range complementary to existing experiments such as LIGO, VIRGO, GEO600, and the planned LISA space antenna 112,113 , and frame-dragging effects 114 . Furthermore, large-mass experiments in space will unavoidably provide a formidable platform for applications in Earth and planet observation 115,116 , where large-mass mechanical systems have already shown a superb capability as force and acceleration sensors 78,[117][118][119][120][121][122][123][124][125] , including in rotational mechanical modes 55,126 .…”

Quantum technologies are opening novel avenues for applied and fundamental science at an impressive pace. In this perspective article, we focus on the promises coming from the combination of quantum technologies and space science to test the very foundations of quantum physics and, possibly, new physics. In particular, we survey the field of mesoscopic superpositions of nanoparticles and the potential of interferometric and non-interferometric experiments in space for the investigation of the superposition principle of quantum mechanics and the quantum-to-classical transition. We delve into the possibilities offered by the state-of-the-art of nanoparticle physics projected in the space environment and discuss the numerous challenges, and the corresponding potential advancements, that the space environment presents. In doing this, we also offer an ab-initio estimate of the potential of space-based interferometry with some of the largest systems ever considered and show that there is room for tests of quantum mechanics at an unprecedented level of detail.
