Try everything Brilliant has to offer at https:\/\/brilliant.org\/PhysicsExplained \u2014 and get 20% off an annual premium subscription.\n\nEach time we\u2019ve built a new tool to look deeper into nature, we\u2019ve uncovered hidden worlds \u2014 from cells and atoms to quarks and fields. But can we keep zooming in forever?\n\nAt first, shorter wavelengths mean finer detail. Yet if we push far enough, the energy required to probe smaller regions would collapse spacetime itself, forming a black hole. This defines a fundamental boundary \u2014 the Planck length \u2014 where quantum mechanics and gravity meet, and the very concept of distance ceases to have meaning.\n\n\ud83d\udcda References and Further Reading\n\nPossible Connection Between Gravitation and Fundamental Length \u2014 C.

There is a growing community of independent learners who are keen to explore modern ideas in physics with the aid of mathematical reasoning. This channel aims to tackle advanced topics head on whilst at the same time providing a historical narrative to help provide context to the ideas. \n\nA bit about my educational background: I have a PhD in theoretical physics, specialising in string theory. I now dedicate most of my my time to physics education.\n\nYou can help support this channel via the Physics Explained Patreon account: https:\/\/www.patreon.com\/physicsexplained\n","logo":{"url":"https:\/\/yt3.ggpht.com\/ytc\/AIdro_nZGuvYl7MLFflLBsXBo4mX8iMYl6GAycYDhvk9NOlM6X4=s800-c-k-c0x00ffffff-no-rj","width":800,"height":800,"@type":"ImageObject","@id":"https:\/\/www.youtube.com\/watch?v=f3jhbui5Cqs#VideoObject_publisher_logo_ImageObject"}},"potentialAction":{"@type":"SeekToAction","@id":"https:\/\/www.youtube.com\/watch?v=f3jhbui5Cqs#VideoObject_potentialAction","target":"https:\/\/www.youtube.com\/watch?v=f3jhbui5Cqs&t={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"},"interactionStatistic":[[{"@type":"InteractionCounter","@id":"https:\/\/www.youtube.com\/watch?v=f3jhbui5Cqs#VideoObject_interactionStatistic_WatchAction","interactionType":{"@type":"WatchAction"},"userInteractionCount":1641040}],{"@type":"InteractionCounter","@id":"https:\/\/www.youtube.com\/watch?v=f3jhbui5Cqs#VideoObject_interactionStatistic_LikeAction","interactionType":{"@type":"LikeAction"},"userInteractionCount":35621}]},"about":["Insights","\u300eEnglish\u300f"],"wordCount":1512},{"@context":"https:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Insights","item":"https:\/\/blog.terabox.com\/insights\/#breadcrumbitem"},{"@type":"ListItem","position":2,"name":"Why the Universe Forbids a Final Zoom: The Plank Limit","item":"https:\/\/blog.terabox.com\/insights\/plank-length-ultimate-resolution-limit-physics#breadcrumbitem"}]}]
