There Are Thousands of Alien Empires in The Milky Way

Kurzgesagt – In a Nutshell・2 minutes read

There could be alien empires in the Milky Way, but no civilizations have visited Earth yet, leaving humanity seemingly alone. The challenges of space colonization and the vast distances between star systems question the feasibility and sustainability of potential galactic expansion.

Insights

  • Despite the vast number of star systems in the Milky Way, the absence of alien visitations to Earth has led to the assumption that humanity may be alone in the galaxy.
  • Comparing potential space colonization to the human colonization of Oceania suggests that space exploration might face similar challenges, questioning the ease of galactic expansion and the sustainability of advanced civilizations.
