Kind of, but probably not. I'm going to try to explain it, and a lot of this will be super simplified (and a little wrong). With computers, numbers are limited to a certain range of either size or accuracy. This wikipedia page explains it a little more. https://en.wikipedia.org/wiki/32-bit The higher the bit, the bigger (or more accurate) the number. But as you get further and further away from 0, the numbers begin to be less precise. This becomes an issue really, really far away from zero and will almost be as if the number is rounding itself. So things become jittery. Another issue is because things aren't as smooth, you start to have scenarios that wouldn't exist otherwhys. In Minecraft, if you travel far enough away (millions and millions of blocks away) the world generator suddenly goes crazy, physics don't work, and so fourth. That's because the numbers can't maintain the accuracy anymore. --- So you can have a huge, huge map. But it (probably) isn't infinite. There are a lot of ways to fix it. Kerbal Space Program avoids it by teleporting the world and player back to 0,0 for physics, and handles orbital physics and calculations with much higher bit sizes.
