impactful is still a lowsy word

Whenever I try to stretch my mind to contemplate the vastness of space and the strangeness of its other inhabitants, the exercise causes my appreciation for every-day existence on Earth to swell. Even if I do occasionally forget that Carl Sagan and Isaac Asimov were two different people, their work impresses itself upon my mind in a likewise impactful fashion. That's correct. Impactful. Like a giant meteorite. Per ardua, ad astra, ad terra firma? Hooray!
