After a brief review of the experimental situation, I will show the potential implications of this \u201cHubble tension\u201d for new physics. I will argue that it points to some new mechanism at play in the pre- recombination universe (i.e., z &gt; 1000), rather than a new dynamical effect at late-time (i.e. 0 &lt; z &lt; 1). I will discuss some model-independent implications of the Hubble tension that can help shed light on its origin.<br \/>\nhttps:\/\/indico.in2p3.fr\/event\/35427\/<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speakers: Vivian Poulin (LUPM (CNRS &amp; U. de Montpellier)) Over the last decade, measurements of the expansion rate of the universe today, H0, made with cepheid-calibrated SN1a have become increasingly [&hellip;]<\/p>\n","protected":false},"author":8,"featured_media":0,"template":"","meta":{"_acf_changed":false,"_tribe_events_status":"","_tribe_events_status_reason":"","footnotes":""},"tags":[],"tribe_events_cat":[],"class_list":["post-9097","tribe_events","type-tribe_events","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/9097","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/users\/8"}],"version-history":[{"count":2,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/9097\/revisions"}],"predecessor-version":[{"id":9455,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/9097\/revisions\/9455"}],"wp:attachment":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/media?parent=9097"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tags?post=9097"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events_cat?post=9097"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
