The nature of time as emergent for a system by separating it from its environment has been put forward by Page and Wootters [Phys. Rev. D 27, 2885 (1983)] in a quantum mechanical setting neglecting interaction between system and environment. Here, we add strong support to the relational concept of t…

This paper explores the enduring black hole information and firewall paradoxes, challenges that have prompted many proposals, conjectures, and theories. Noteworthy among these are the ER = EPR conjecture and AdS/CFT correspondence, which suggest possible avenues toward the yet-to-be-realized unified theory of quantum gravity. This discourse offers a comprehensive analysis of the aforementioned paradoxes, drawing upon insights from efforts to reconcile the schism between general relativity and quantum mechanics.

The simplest cosmological model ($\Lambda$CDM) is well-known to suffer from the Hubble tension, namely an almost $5 \sigma$ discrepancy between the (model-based) early-time determination of the Hubble constant $H_0$ and its late-time (and model-independent) determination. To circumvent this, we introduce an additional energy source that varies with the redshift as $(1 + z)^n$, where $0 < n < 3$, and test it against the Pantheon Compilation of Type Ia Supernovae as well as the CMBR observations (at $z \approx 1100$). The deduced $H_0$ is now well-consistent with the value obtained from local observations of Cepheid variables. Suggesting a non-zero value for the curvature density parameter, positive (negative) for $n > 2$ ($n < 2$), the resolution is also consistent with the BAO data.

The significance of anomalous weak values has been a matter of great debate in quantum foundations and quantum information. Here, a simple proof shows that the weak-value anomaly requires both negativity of a certain quasiprobability representation and coherence of pre- and postselected states in the observable’s basis.
