*LIVESTREAM <https://youtu.be/IX9mVzEqzR8>* | *PERMALINK <https://isoc.live/19737>* [image: ISOC LIVE] On *Wednesday October 8, 2025*, at* 2pm-3pm EDT* (18:00-19:00 UTC) the *Interplanetary Networking Special Interest Group <https://ipnsig.org/>* (IPNSIG) presents an IPNSIG Academy Keynote ‘*Interplanetary and Relativistic Distributed Computing*‘. *Siddhartha Jayanti <https://www.linkedin.com/in/siddhartha-jayanti-a31b27271/>* will examine interplanetary distributed systems, such as the Interplanetary Internet, and the Global Positioning System (GPS) which are subject to the effects of Einstein’s theory of relativity. In this talk, we will formulate a unified computational model for relativistic and classical distributed computing systems and study the relationship between properties of distributed algorithms deployed on the two types of systems. *SPEAKER* *Siddhartha Jayanti* – Assistant Professor of Computer Science, Dartmouth College) *MODERATOR* *Ginny Spicer –* IPNSIG -- -------------------------------------- Joly MacFie +12185659365 -------------------------------------- -
