All science creates these days are skeptics. Dreamers need to look elsewhere. God forbid we break some physical "laws" and get some actual new, tangible physics in our lifetimes. I'm glad they are taking it up and trying it. Even if it doesn't work, it's one thing we've ruled out. We need to accept the fact that without a substantial propulsion breakthrough we will be stuck here, so we need to start looking enthusiastically, even if it means looking under rocks or throwing things at the wall to see if they stick.
