Physics is a special case. Either we are unimaginative or we have truly started reaching the limits of what can and cannot be found. I think it's a mix of both but also I'm not a physicist so don't listen to me too much.

You might accuse me of calling Physicists of being unimaginative but I truly believe that to be the case. The most fascinating topic in this regard is the alcubierre drive; before that concept became famous when I asked any Physicist if we are truly stuck in our solar system for eternity due to light speed limit they said yes, it's actually mathematically absurd to even think of any other possibility. Then this topic comes, and as impossible as it sounds it's at least not absurd mathematically (absurd physically still, sure but I feel theres a difference). So it's wierd that more Physicists are not grabbing at crazy tails like this and truly push what their imagination can conjure up.
