I find the idea of colonizing other planets for human habitation really fascinating. It's also amazing to see so much investing and resources put into the idea, despite it paying back kinda poorly, at least in short term. Of course there are many ethical aspects to it, like should we go and shape and eventually destroy other planets too, like we are doing to our home planet currently? I think that since the Mars for example is (apparently) "dead" planet, it's okay for us to infect it with humans. In some way think it's even "logical" and "makes sense" for us to bring life to Mars.
Here's a great animation and simulation on how the preparations for the first colony could happen;
I suppose this counts as an interest. I stumbled across this guy's videos a while back when I was looking for 80s and 90s nostalgia. For some reason I kept clicking on more of his videos and now his videos show up in my feed all the time and I can't seem to stop watching them. I never thought it would be so interesting watching some stranger's home movies from the past.
I think he has a following of people who found his videos the same way I did.
I mean looking at it, with the new one you're not going to be able to have a lightsabre fight like in the films since it's supposed to solidify in contact with other objects like other lightsabres so it resembles a sword fight so you're still sacrificing something either way. You either sacrifice some of it's functionality for aesthetic or the other way around.
EDIT - By the way, here is another video from the same guy describing how he did it. Interesting fact - I was about 3/4 of the way through building this exact kit when I heard the James Cameron Titanic movie was coming out in 1996-1997. I almost finished mine but for some reason stopped working on it. I don't know what ever became of it. You wouldn't think something that large could go missing for very long but I couldn't tell you where it went.
By the way. I was building mine to look like it was supposed to. Not like the wreck. Even that was hard so I can imagine what it must be like to make an accurate model of the wreck.
