    Considering we only know it’s there because it slightly dims the light from its star as it crosses during its orbit, you would be correct. At that distance, we would never see light bouncing off the actual planet. Even the star is basically a single pixel. We can estimate its size and orbit based on how quickly it crosses in front of the star and how much the light dims, and using those two numbers we can estimate its distance from Kepler 452.







  • I did something similar with an old spare phone for a while when my actual phone screen stopped working. I carried both around, but I found 90% of my use cases didn’t involve phone calls or even texting.

    I do find it convenient to have my phone connected to tailscale so I can access my home network from anywhere.

    And I don’t necessarily trust public wifi.

    But otherwise, I fully support this and think it’s entirely viable for most people.


  • With one linear timeline, you basically have Back to the Future rules. You can go back and change things, even if it rewrites you out of existence. Of course, there are some logical paradoxes that arise from that theory of time, so most versions rely on some delayed repair mechanism, like how the photo of Marty slowly disappears, or how The Ancient One explains the Time Stone to Professor Hulk. Time Cop, Butterfly Effect, and Looper do the same, with changes going into immediate effect like old injuries becoming later scars in real time, but erasing yourself really ought to be devastating to spacetime itself. I liked the concept in Butterfly Effect where the time traveler experiences all the memories of their new life in the altered timeline with every new change, but then they abandon the hard sci-fi aspect to get cute with stigmata. Donnie Darko probably handles it the best, where time travel itself creates a universe-ending paradox that requires the destruction of the time traveler.

    Essentially, you jump from now back to another location in spacetime where you didn’t exist the first time around. If you overlap with yourself, you’re either going to gain a new retroactive memory, or there’s some magical maguffin that erased the memory (like the Tardis does for the Doctor), or some universal force reconciles the timestream and eliminates the paradox.




  • I oppose it simply because it doesn’t work. It is not a deterrent, and it does not serve justice to put people to death, and it costs far more to execute someone than it does to rehabilitate them (the most expensive alternative - I’m not suggesting rehabilitation is an option for everyone).

    And sometimes we execute innocent people. Like, how many of your family members would you be willing to put to death to keep the death penalty? Every innocent victim of the death penalty had a family, and that family never imagined it could happen to them.

    Ugh that drives me crazy. The human eye is a perfect example of observable evolution. Organisms exist with every stage of eye development, from a photosensitive spot to a more advanced convergent evolution of our eye. And the human eye is poorly designed for it’s current use, resulting in a significant percentage of people requiring corrective lenses.
