Traversing the milky way galaxy! when??? Traversing our own galaxy is a lifelong quest for me and I am actually pondering it and long for it all the time, except when I am sleeping. Maybe it's just a fantasy, though I am not into science-fiction version of it, but many of us want to eventually someday be able to travel to distant worlds and find out more about us, don't we? Modern biology and astrobiology tells us that formation of life is possible wherever in the universe when the right conditions exist...So to traverse the universe in search of life mainly or of a livable planet like Earth, what possible methods are now being considered or discussed? Is there any prospect of travelling to the nearby solar systems and planets in the near future? What do we need to discover/figure out first if haven't already? Thanks in advance for your comments on this.
