  1. For Questions That Don't Merit Their Own Thread

    Explosives can be "shaped" to direct most of their energy in a certain direction, perhaps the same can be done with EMPs? In the video I perceived them as being like a flying anti-tank mine, so windows aren't the only thing they can get through. Again, I think they could break through that. This could work, I think. Also, here's an idea my mum thought of: A modified water hose that shoots really strong acid instead of water. Probably impractical but worth mentioning.
  2. The size of Spore's Planets.

    I personally don't mind it at all. There is still plenty to explore even on such small planets, in theory at least. Plus it makes civilian space travel easier, not to mention the short travel times. At the very least it would make a nice game setting.

    What would be the best defence against the nightmare fuel in the new short film "slaughterbots"? Here's my current opinion: Projectile weapons: useless Lasers: useless unless the beam width can be expanded and the laser power can be increased significantly EMPs: Could work Nukes: Too hard to acquire, but would certainly work
  4. Russia's new SHLV plan

    Hate, haters will. So, to recap, here's all the space programs that are developing heavy-lift rocket systems: Blue Origin (New Glenn) SpaceX (Falcon Heavy, BFR) CALT (Long March 9) Rokosmos (This new system)
  5. Your Favorite Anime

    Hmm... my top 3 would have to be Code Geass, Attack on Titan and Death Note (the latter of which I've been writing an FF for for over a year now). I'm also a fan of Hetalia, Assasination Classroom, Black Butler, and a few others.
  6. Where do you get your news from?

    ...But seriously, I get most of my news from a range of independent, alternative media organizations.
  7. The size of Spore's Planets.

    Weather update: I think I've figured out how this all works! In Isaac Arthur's new video "Mega Earths", he mentions that an artificial planet could be made by placing a "shell" of orbital rings around a black hole, and then placing a layer of dirt, rocks etc on top of that to create a world vastly different in size to any natural planets. For an Earthlike planet in Spore, such a black hole would have a radius of 0.03759644 nanometers, a hawking radiation energy output of 0.5558304 W, and a lifetime far exceeding the age of the universe. Of course, this only solves the problem of gravity, not how the planets hold onto their atmospheres, or how the orbits can remain stable considering that the ratio of planet-moon, planet-star and interstellar distances.
  8. What funny/interesting thing happened in your life today?

    When I was unpacking my school bag I couldn't find my phone, and I was completely horrified and panicking until I found it in my pencil case.
  9. Thanks. So it looks like this really is the second closest potentially habitable world after Proxima. Still, at 0.1c a colony ship would take over a century to get there. Then again, Stonehenge and the GWOC both took nearly 2000 years to complete, so I guess it may be possible.
  10. I once read that plants around a red dwarf would be black instead of green. As for eyesight, the difference probably wouldn't be as visible as you'd think.
  11. It's fun to think about, even if interstellar travel is a long way away.
  12. Back In My Day...

    Back in my day, you had to go through a systemised psychological torture system for several years just to get into college! Back in my day, there were only eight known planets! Back in my day, some people still thought NASA would recover eventually! Back in my day, Bill Wurtz and Vsauce were just youtubers! Back in my day, the supreme empire of greater Korea was just a tiny state next to China! Back in my day, we had to deal with damn eight legged abominations called "spiders"! You kids probably haven't seen one, but back in my day they were in our classrooms, our homes, everywhere! Back in my day, when we wanted to write something down, we actually had to physically write it down! Back in my day, we couldn't just do as many things on our computers as once! We even had to avoid using full graphics and stuff just so the computer wouldn't lag! Back in my day, computers just had a flat screen! It didn't even change if you looked from a different angle! Every four years, everyone in America would ritually complain about things to one another. "The Expanse" wasn't always a documentary, it was originally an anime. Nikola Tesla invented the first atomic bomb, but Thomas Edison later took all the credit.
  13. The size of Spore's Planets.

    By the way, I calculated that the average "sunlike" star must have an energy output of 613GW to provide the same amount of energy to a planet one 25-millionth of an AU away as Earth gets from Sol. So by Spore standards we're above K2 status.
  14. The size of Spore's Planets.

    This size range actually isn't too uncommon in space games. Other examples of small solar systems that I can find include: Space Engineers: Planets are 19-120km in diameter, "Earth" and "Mars" are 2000-4000km apart. Outer Wilds: The sun is 4km in diameter, and the comet orbits from 0.4km to 22km from the sun's surface. Every single "build a rocket and fly into space" in-browser game that has ever been made (Into Space 2 was my favourite as a little kid) Galacticraft mod in Minecraft: Karman line appears to be less than 1200 meters above sea level. I know it isn't a very "intellectual" game but I figured it's worth mentioning. Toy Solar System mod in KSP: All planet sizes and distances are scaled down to 1/10th of their normal values. Interestingly, this is the only example that scales down the planets/moons and the distances between them by the same amount, so the distances relative to the sizes stay the same. This: On a side note, worlds like this open an interesting possibility of a "rocketpunk" world where even a few teenagers would be able to build something that can fly between planets. An interesting sci-fi setting I'm thinking of is perhaps one where the surface of an Earthlike planet in a Sporelike galaxy is connected to Earth in a nearby abandoned warehouse or something.

    Would an Alderson Disk have more habitable land area than a Ringworld? And which one of the two would require more building material? Alternatively, is there any similarly vast artificial habitat idea with even more area?
