@fact_mike: The Observable Universe Is 93 Billion Light-Years Wide… Yet Humans Have Only Traveled 1.3 Light-Seconds The observable universe spans more than 93 billion light-years across, containing everything whose light has had time to reach us since the Big Bang. Now compare that to the farthest journey humans have ever made. During the Apollo missions, astronauts traveled about 400,000 kilometers (250,000 miles) from Earth to the Moon — a distance of just 1.3 light-seconds. From a cosmic perspective, that's an incredibly small step. While we've explored our Moon and sent robotic spacecraft throughout the Solar System, human spaceflight has ventured only a tiny distance beyond Earth. Meanwhile, the universe stretches across scales so vast that light itself takes billions of years to cross them. It's a reminder of both how far we've come and how much remains to be explored. Humanity has taken its first steps into space. The rest of the universe is still waiting. #DidYouKnow #universe #fact #fyp
