As long as mankind exists we are bursting our frontiers. Einstein bursted the frontiers of physics in the beginning of the 20th century and Columbus bursted our frontiers when "Land was sighted at 2 a.m. on 12 October 1492" [Wikipedia.org]. 518 years and 6 days later I'll burst my own frontier by setting foot on American ground.
Maybe human race once will be able to travel to the stars. Making dreams come true and expanding its consciousness like its outreach. But in our days it lasts out just to travel to another continent =) to grow your awareness, enrich you personality with a lot of new experience, get to know to new ways of thinking and beeing and spend a great time in your live!
Well, so far the introduction, but what it's really like, I will see on October 18.
