Hope springs eternal for die-hard Star Trek fans that scientists will one day build an actual, working antimatter propulsion engine similar to the one that powers the fictional starship Enterprise.
A paper published earlier this year by a pair of enterprising (get it?) physicists should fan the flames of that fantasy even further. The results from their computer simulations indicate that at least one key component of realizing a working antimatter propulsion engine — highly efficient magnetic nozzles — should be far more efficient than previously thought. And such nozzles are feasible using today’s technologies.
