What’s perhaps surprising about these galaxies is that the farther away we find them, the faster they appear to be moving away from us. This was one of the most puzzling discoveries of the early 20th century…
Of the hundreds of billions of galaxies (maybe even as many as a trillion) in our Universe today, only about 3% of them are still reachable.
It’s pretty crazy to think about what Ethan Siegel describes. Only a small percentage of the visible Universe would be still reachable by travelling at the speed of light. Even though 3% is still mind-bogglingly huge, we need that wormhole tech right now! ;)
Matt Gemmell’s piece on empathy is one of the best articles I’ve read recently.
When I was younger, I was convinced that the important part of what I was doing was the output itself.
As I’ve grown a little older, I’ve realised how misguided I was. The truth is that the importance of something you create doesn’t even exist yet while you’re making it, and you start at zero when it reaches other people. The most important, and most life-changing lesson I’ve learned is that everything is about people’s reactions.
You Know Nothing is a great little handbook for the characters of Game of Thrones.
