Think about it, we often hear as scientists-this is impossible that is impossible. But is it? It is possible to walk up a wall and it is possible to travel faster than light, we just don't know or even understand the means behind making them so. But just for a change in my philosiphy, can it actually be possible that something is impossible?
An example, can God's existence be possiblly impossible. Is it impossible for an atheist to turn into a full believer? I suppose it can derive from optimism and pessimsm, the glass if hall full/empty argument, but still from a scientific point of view is something that which cannot be proven possible impossible?
