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 …

We review the question of whether the fundamental laws of nature limit our ability to probe
arbitrarily short distances. First, we examine what insights can be gained from thought …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

According to a number of arguments in quantum gravity, both model-dependent and model-
independent, Heisenberg's uncertainty principle is modified when approaching the Planck …

Attempts to formulate a quantum theory of gravitation are collectively known as quantum
gravity. Various approaches to quantum gravity such as string theory and loop quantum …

In this work we investigate a Schwarzschild-type black hole that is corrected by the
Generalised Uncertainty Principle (GUP) and possesses topological defects within the …

In this paper, we review some highlights from the String theory, the black hole physics and
the doubly special relativity and some thought experiments which were suggested to probe …

Based on string theory, black hole physics, doubly special relativity and some'thought'
experiments, minimal distance and/or maximum momentum are proposed. As alternatives to …

In a recent paper, we presented a nonperturbative higher order Generalized Uncertainty
Principle (GUP) that is consistent with various proposals of quantum gravity such as string …

We investigate shadows, deflection angle, quasinormal modes (QNMs), and sparsity of
Hawking radiation of the Schwarzschild string cloud black hole's solution after applying …
