I love infinity. The idea of it is so abstract and so far from possible to imagine, that it give one feelings of overwhelmement and dread, yet it is so fulfilling and emptying, it can help me relax. It's an intoxicating feeling that makes me crave for it, more and more.
There is a video on YouTube. ,The Shape of Infinity' by Jacob Geller. I saw it a couple of days ago, and it sums up a part of what I feel.
Jacob Geller has also made a video about depths, which is also a video I heavily recommend.
There is also a YouTuber by the name of exurb1a. His videos are... thought provoking and poetic. They are interesting. These two channels are ones I recommend you to check out. I hope you'll enjoy their content.
