Sailing To Another Galaxy
Earth/ Sky News tells us of a concept developed by some phsycists that might enable man to travel to our nearest galaxy, Alpha Centauri, within 20 years. That system being four light years away, which means it would take four years for just light to travel that far and we can't go light speed...yet.
The Breakthrough Starshot plan would use solar sails- the description reminiscent of the solar sail craft used by Captain Cisco in Star Trek's Deep Space Nine show. Pretty neat, but I won't be volunteering for that mission. I wouldn't want to go anywhere unless I knew I could make it back.
