We don't talk about Pun-Pun
Because our understanding of things is always changing. History is full of people who thought this or that thing was "impossible" only to be eventually proven wrong. We can say that things are impossible according to the laws of physics, for example, but we do not know everything there is to know about physics.But plenty of things are flat-out impossible. Why is it wrong-minded to acknowledge it?
Take the ability for a human to run a sub-4-minute mile. Experts for a long time claimed that the human body couldn't take the strain of such a feat. Then Sir Roger Bannister did it. Now it's a benchmark for runners.
Our understanding of our universe changes all the time. This isn't to say that there cannot be impossible things, but at any moment, what we presume is impossible could be contradicted, so I feel that it's always better to keep an open mind, no matter how improbable something may seem to be.
The ability for a human to fly through the air without some device to defy gravity is currently impossible. I think we can all agree on that. But when the day comes that someone falls and misses the ground, we'll all feel a bit silly, won't we? : )
