I thought you knew the reasons why. Yes, that's right. Eric D's been
interested in interstellar travel for a long time. He's done some work
and thinking about it, but I don't think any of his work is in a
presentable written form.
Robert too, but I think that he's more interested in where is the
carbon (looking for M-brains).
BTW, interplanetary spacecraft for a few decades now have been using
shielding and other methods to ward against dust impacts (I can say
more about that in the future, but not now).

P.S. And don't forget that the Universe is a plasma with localized
magnetic fields.
