O palmar\u00e9s hist\u00f3rico incl\u00fae figuras como Stephen Hawking e Roger Penrose e varios premios nobel como George Smoot, Gerard&#8217;t Hooft ou Frank Wilczek.<\/p>\n<p>O ensaio galardoado, asinado xunto a Gustavo Arciniega, Pablo Bueno, Pablo Cano, Robie Hennigar e Luisa Jaime, presenta un <a href=\"https:\/\/arxiv.org\/pdf\/1812.11187.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">traballo<\/a> no que se identifica un mecanismo que explicar\u00eda a r\u00e1pida expansi\u00f3n do Universo no per\u00edodo denominado inflaci\u00f3n, onde este expandiuse cencuatrillones de veces en menos dunha quintillon\u00e9sima de segundo, pouco despois do Big Bang. Os autores propo\u00f1en que este crecemento acelerado poder\u00eda deberse \u00e1 propia natureza xeom\u00e9trica da gravitaci\u00f3n e non a un axente externo denominado inflat\u00f3n, como prescribe a explicaci\u00f3n m\u00e1is aceptada. O mecanismo de inflaci\u00f3n xeom\u00e9trica que se promove no ensaio titulado \u201cCosmic inflation without inflaton\u201d mostra que, baixo a hip\u00f3tese de que a gravitaci\u00f3n e a mec\u00e1nica cu\u00e1ntica foron compatibles naqueles instantes, a expansi\u00f3n exponencial do Universo temper\u00e1n ser\u00eda inevitable.<\/p>\n<p>A Gravity Research Foundation foi fundada por Roger W. Babson en 1949 co obxectivo de estimular a investigaci\u00f3n sobre a gravidade, as s\u00faas aplicaci\u00f3ns e efectos, creando un concurso anual de ensaios cient\u00edficos. Nesta \u00faltima edici\u00f3n, o primeiro premio recaeu nun traballo de Alessio Belenchia, Robert M. Wald, Flaminia Giacomini, Esteban Castro-Ruiz, Caslav Brukner e Markus Aspelmeyer.<\/p>\n<p>Artigo no que se basea o ensaio:<br \/>\nArciniega, G., Bueno, P., Cano, P. A., Edelstein, J.
