Probably biased by the physicist I mostly listen to because they have a lot of lectures and talks online, Leonard Susskind and Nima Arkani-Hamed.<p>The idea that space is quantized is pretty unlikely to be true because of relativity, i.e. because of length contraction the size of those space quanta depends on the motion of the observer. So if you find those space quanta have a specific size in your reference frame I can just go to a reference frame moving relative to yours and I will see length contracted space quanta and we will therefore disagree on their size.<p>It is actually believed that neither space nor time are fundamental but that they emerge from something more fundamental because spacetime, relativity and quantum physics taken together are not really compatible, see for example &quot;Space-time is doomed. What replaces it?&quot; [1]. Susskind explores the idea that entanglement is what holds space together under the name &quot;ER = EPR&quot; [2].<p>[1] <a href="http:&#x2F;&#x2F;www.cornell.edu&#x2F;video&#x2F;nima-arkani-hamed-spacetime-is-doomed" rel="nofollow">http:&#x2F;&#x2F;www.cornell.edu&#x2F;video&#x2F;nima-arkani-hamed-spacetime-is-...</a><p>[2] <a href="https:&#x2F;&#x2F;youtube.com&#x2F;watch?v=OBPpRqxY8Uw" rel="nofollow">https:&#x2F;&#x2F;youtube.com&#x2F;watch?v=OBPpRqxY8Uw</a>
