Existing theories of this &#8216;quantum gravity&#8217; often involve mathematical corrections to Heisenberg&#8217;s Uncertainty Principle (HUP), which quantifies the inherent limits in the accuracy of any quantum measurement. These corrections arise when gravitational interactions are considered, leading to a &#8216;Generalized Uncertainty Principle&#8217; (GUP). Two specific GUP models are often used: the first modifies the HUP with a linear correction, while the second introduces a quadratic one. Through new research published in EPJ C, Serena Giardino and Vincenzo Salzano at the University of Szczecin in Poland have used well-established cosmological observations to place tighter constraints on the quadratic model, while discrediting the linear model.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-02-cosmological-constraints-quantum-gravity-phenomenology.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Placing cosmological constraints on quantum gravity phenomenology<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A description of gravity compatible with the principles of quantum mechanics has long been a widely pursued goal in physics.
