I mean sure, it's true there's still ambiguous usage. But that doesn't change the fact that hard drive manufacturer use the powers of 1000, which is what the previous comment was about.

No, the powers of 1024 are called "Kibibyte (KiB)", " Mebibyte (MiB) and "Gibibyte (GiB)" (those are called "binary prefixes"). Gigabyte is 1000^3. This is why hard drive manufacturers use Gb instead of Gib, because it lets them sell a smaller drive with the same number before the prefix (2 TB < 2 TiB).
Prior to 1998, it was ambiguous, and some usages of the metric prefixes to denote 1024^n persist to this day (hello Windows). But nowadays any usage of 1024^n should absolutely use the binary prefixes.

There doesn’t need to be a normal at all. Mathematically, the properties/content of surface of a sphere can be completely described without having to think about an embedding space. The word “surface”/“hypersurface” is a bit misleading in this context because it implies an embedding space (It just means object of dimension N-1 in an embedding space of N dimensions) (sometimes the word hypersurface is used when N ≠ 3). But when we say “surface of a sphere”, the “sphere” and the space around it is only a visualization tool, it doesn’t need to be considered as a “physical thing”. If we don’t want to talk about an embedding we can just say we are talking about “a space with positive curvature” or a “spherical space”.

Here’s a video of what it’s like to live in a spherical world (a very small one with a very high curvature): https://www.youtube.com/watch?v=yY9GAyJtuJ0 Here it must be noted, they added a ground to their world to help visualize stuff but it would works without it as well. If nothing obstructed your view, you’d end up seeing yourself in all your vision, as if you were inverted like the house of the video. Trippy stuff!

It’s only one of many possibilities, we have no idea about the actual topology of the universe. It could also be infinite

You’re probably picturing the inside 3D sphere, but it would actually be the surface of a 4D sphere. Just like how Earth doesn’t have an “edge”, if you walk in a straight line you just end up where you started, so there’s nothing to “push” at all

Love to see Löve! It’s what really got me into programming & gamedev, super fun engine to play with :D Nice rice!

You try to land on the moon but you just keep missing for some reason. So you go to read alien scriptures on some hourglass or whatever
