  • There is essentially no way we are the only ones in the entire universe. It would have to be the most astounding and amazing luck for that to be the case…. Vanishingly small, might as well be zero, chance of being the only ones. The universe is an absolute monster in size. There is no way for our monkey brains to even fathom how big it is. We need abstract numbers to even talk about it, which make it so anything that could exist most likely does.

    However, those extraterrestrial peers of ours may be so far away that we might as well be alone. Even if we traveled for millions of years and kept our warring civilization from destroying itself, we may only explore a small percentage of this one single galaxy. Even if we managed to catalogued the entire thing, there are still 200 billion more galaxies out there. Our alien buddies may be on one of those that will soon blip out of existence due to universal expansion before we could get there, even if we traveled at maximum speed, never to be seen or heard from again.

    When we talk about actually attainable and achievable exploration goals, the chances of other intelligent life existing get sort of really small. That is what I find to be not terrifying, but somewhat depressing to think about.



  • As I understand it, if you were a photon this trip would be instantaneous from your perspective due to time dilation. You emit from the event, you collide with and energize some particle billions of light years away at the same exact moment.

    But what if you never hit anything? Do you experience time then? Seems that no collision is likely in a mostly empty, but finite universe.

    Or perhaps the universe is infinite, making it a certainty that you hit something eventually. In that case every photon hits something, almost implying a conservation of photons.

    I thought that was interesting to ponder…








  • I used to interview all the time. I thought it was a fun, important process, so they kept giving them to me… until one day a candidate stormed out. We had a panel on one side of the table that had devolved into one-upping each other on who could ask the best brain teasers. Finally the candidate literally said, “Fuck this.” Then got up and walked out. HR asked us WTF and we shrugged and blew it off, but I knew why. We all knew.

    Sometime after that I changed my tact into making interviews conversations to get to know each other instead. If I did send someone to a whiteboard, I always got off my ass and joined them up there. Made it a collaboration exercise and never asked any bullshit. Did that for maybe six months to a year and got some awesome people from that process…

    At the end of that stretch, HR sat in on one and saw the process for the first time… sometime later I stopped being asked to interview. No reason was given, the invites just stopped coming in. We kept hiring people but I wasn’t a part of it anymore. Coincidence?




  • Imagine if we evolved on Earth like normal but were in orbit around a star that had been ejected maybe a billion years before. And when our sentient eyes turned skyward for the first time we saw only profound blackness. The only points in the night sky are other planets in our solar system and perhaps the moon. No constellations, no nebulae, no exoplanet discovery, nothing. Just a few dim smudges where the Milky Way is, and perhaps a fundamentally different understanding of the cosmos.
