We could easily explore space and reach other galaxies. We were contacted by a higher race of beings in the 1950s after detonation of nuclear devices sent out massive EMPs alerting them to our presence. They assured us that until we can act responsibly on our own planet we'll never be welcome outside of it. The ((((CURRENT EVENTS))) are a good example of why we don't really deserve to explore the heavens. Imagine if we let those sorts leave Earth and spread their horseshit to other planets and species?
