I know it would take an obscene amount of energy to put any type of manned spaceship within reach of neighboring stars... but why can't tiny probes, maybe the size of a baseball, or if necessary a marble, be sent instead? Say we explode a nuke to fling a few of these 'spaceballs' towards Proxima centauri... would the energy imparted be enough to get it there within a single human lifespan? If so, why isn't it being done?
