Hi, I’m sbird! I like programming and am interested in Astrophysics and all things space. I also have a hobby of photography.

  • In Australia, I would definitely say Victoria is the best state. I’m from Melbourne though, so I’m a bit biased. Tasmania is also really neat as well. I haven’t visited any of the others, but realistically it’s hard to find the “worst” state in Australia, since they are mostly just big coastal cities with a lot of desert inland. The only exception is the Australian Capital Territory, which is just Canberra and the surrounding area, so unless you really like Canberra there is not much to do (none of the national parks, sightseeing, etc. that Australia is known for)




  • A lot of people have already mentioned neutron bombs, which are more immediate, but things like infected hoards of mosquitoes, rats, etc. would be devastating, especially for urban populations. One of the main reasons why the native peoples in the Americas and Australia didn’t put up much of a resistance against European colonialism was due to the spread of foreign diseases killing the majority of the population, and in many cases, the idea of deliberate infections has been brought up (whether this was implemented is pretty controversial and still an open question). The Black Death is another example, and aside from how many people died from it across Eurasia, the corpses of those who died from the plague were used as a weapon.

    And of course, you have all the chemical and bioweapons of the 20th century developed by the Germans, the Japanese, the Americans, the Soviets, etc., all of which have been used for mass killings, warfare, and terrorism.








  • Since it’s a laptop, I would set up something like NextDNS (what I often use, but you can also use Cloudflare, ControlD, etc.) in order to block advertisements and unwanted content. Ideally use a Firefox-based browser as then you can use uBlock Origin (+ they are often less memory intensive!) to block additional stuff. Others have already suggested supervision and setting a different user account with fewer privileges. I would highly encourage using a solid Linux distro, as those break less often (especially when the kid becomes / is older and starts going to sketchier websites), and in the modern era they tend to work better too, particularly on older hardware! KDE Plasma and GNOME are both solid desktops available in a variety of distros, or you could go with the reliable Mint w/ Cinnamon.



  • A planetary mass disc would collapse into a sphere. Gravity works towards the centre of mass, so it makes sense that it becomes a sphere once the force is great enough, where the distance from said centre of mass is nearly equal from all points on the surface. it’s the reason why smaller objects are usually oblong and weird shaped (e.g. asteroids) while larger objects are close to spherical (e.g. Pluto!)

    And what do you mean by “uniform gravity”? If you mean for a theoretical person on the planet, it would not be uniform on the edges as you have an imbalance of forces towards either side, while in the centre it is symmetrical, an equal amount of mass on either side. On a perfectly spherical planet, it would all add up to a downward force on any point on the surface
