I was mostly off during these two weeks, but I took some hours to finish the “Time dilation” video and publish it on YouTube. I used this time to shorten and improve the script, create the thumbnail and the video description. I was a bit in a hurry to do all this. I forced myself to publish the video before the New Year, being aware that I have a lot of work to do on the video game.

In hindsight maybe I should have waited. The video didn’t go well and had a poor reception. I’ll write a dedicated post to analyze the results and some possible causes for the bad performance. I may also respin the video a bit and publish it on TikTok, after fixing some of the problems and also following the suggestions made by some subscribers of my YouTube channel. This could be a good opportunity to check whether I understand the YouTube algorithm and my audience well enough.

Time Dilation Visualized

This video explores time dilation, an effect explained by Einstein's Theory of Special Relativity. The video starts by showing that time dilation can prolong the life of a short-lived particle, allowing it to witness events that it couldn't experience if it had its normal short life. The video then focuses on what the particle itself sees. The two accounts of what happens are strikingly different, but are consistent! All observers agree that the particle witnesses an event that it couldn't witness if space and time followed the common-sense rules of Classical Mechanics. This video presents an apparent paradox. It's similar to other relativistic paradoxes. It is somewhat similar to the ladder paradox, but rethought for time dilation rather than length contraction. See https://www.youtube.com/watch?v=vnWNKdY8JtQ for the length-contraction counterpart of this video. I'd also recommend the Sixty Symbols video, https://youtu.be/kGsbBw1I0Rg?feature=shared It explains what happens to muons entering the Earth's atmosphere. It is a real-life example of the effects explained in this video. This video was born during a brainstorming session I did for my relativistic video game. The game aims to make Special Relativity more intuitive. I believe that human intuition can crack relativity if given a chance.

The bodies are discretized into meshes with 3x3 vertices. Each vertex follows a piece-wise hyperbolic trajectory. The video shows the "measured reality" and not the "observed reality". So what you see is what an inertial observer would measure, rather than what an hypothetical camera would record. === Credits === Thanks to all my patrons and, in particular, to those in the Early Supporter tier: - SirCypher - qb20nh - Sketches&Spaghetti - Usagi === Useful links === - Game development and news, https://www.patreon.com/relativisticgame - Game blog and formulas, https://relativisticgame.net - Time dilation, https://en.wikipedia.org/wiki/Time_dilation === Soundtrack === Luminescence by Benjamin Lazzarus
