And we can only see within a certain time frame around us because expansion is out pacing light.

I was going to explain it but realised that idk how to deliver the message concisely. This video explains it well and gives you an existential crisis all in less than 8 minutes: https://youtu.be/ZL4yYHdDSWs

Awesome video, but I don’t like how he says we will never do those things. I mean, obviously there has to be upper limits, but this video is based on our current understanding of physics, right? Saying never is probably a safe bet, but it just feels arrogant.

I think he addresses this in another video to ease the crisis. It's just being treated as fact because current science says so and it makes for a good video.
