so this image is not quite fitting because the wormholes are separated, but if you imagine the sheet glued together at the holes it seems like a good representation of portals in 2d space. That makes the whole idea of 'one portal moving and one stationary' rather weird because you can't think of them as separate objects. You might have something like 'space closer to the orange portal compresses, space closer to the blue one expands', but that would just mean the portals move differently seen from different positions on the connecting line, and are both stationary at the halfway point. Also, if you were an ant on that line, would you actually go through the 'moving' portal or just come arbitrarily close to it? Seems like something would need to give you momentum to go through.

Why do people believe that interstellar travel is a possibility given humanity's current aptitude in physics? Where we are absolutely proves that there is no possible way of traveling with such distances without bringing in /x/-tier stuff. Why do media outlets that are supposed to be factual, preach to people that solar system domination is just within our reach? Is it political? In my personal opinion, research in space should be centered around keeping earth safe from a cataclysmic event like an asteroid strike, not putting an outpost on an inhospitable planet when we are really not ready for something like that.
