  • Pushing Ice by Alastair Reynolds is one of my favorite scifi books and it deals with this question in an interesting way. It proposes that Time is the great filter. Life exists in this galaxy, but intelligent life is so fleeting when considering galactic distances that the probability of one sentient lifeform finding another during their “peaks” is vanishingly small. Extinction, societal collapse, evolution to a higher form, whatever you want to imagine, it all gets in the way of the fantasy of meeting a thinking being from another planet.


  • Time itself is the filter. I don’t think we are the first, but I don’t think we will every find any other intelligent life. The universe is too big and our lives are far too short to make any sort of attempt to travel or communicate across those distances ourselves. I’m also not entirely confident our idea of what a society is will last in any meaningful way over the timespans required. Our longest lasting dynasties rarely make it more than a couple hundred years. Space is just too big for us to work with using our current understanding of physics.



  • Maybe I’m biased because I’m a welder, but it always made more sense to me that electricity flows from the negative. Like , if the positive moved, wouldn’t you change the element of the wire after a while? It also helps that you can tell the difference if an arc is positive or negative relative to the stinger depending on how the metal reacts, at least to a welder. I know that doesn’t make any sense at all but it does to another welder lol







  • Do you worry about UV exposure from the sun?

    You can block the vast majority of harmful welding radiation with a long sleeve tee shirt. Throw on some sunscreen if you’re paranoid about it. I generally wear a lab coat and that’s plenty.

    If you want something to worry about, worry about gas exposure. You can’t see it, generally can’t smell it, and if you can feel it, you’re probably already fucked. Argon asphyxiation is particularly insidious. Close ur eyes for a little snooze on the job and wake up to meet God.
