The Universe, as observed, is over 8.8 x 1026 meters in diameter.

  • Only ~ 5% is ordinary baryonic matter. The rest is unknown.
    • In total, it is 45 billion light years and always expanding in scope.

To help explain scale, roughly 1.3 million copies of Earth could fit in the Sun.

The previous estimate of galaxies was 200 billion (2×1011).

  • Now it is suggested to be 2 trillion (2×1012) galaxies.

Even following a constrained view of 10 billion galaxies (not 2 trillion) there are an average of 100 billion Stars per galaxy.

That equals a billion trillion stars.

Over 1,000,000,000,000,000,000,000 Stars in the observed universe.

You are nowhere near as important as the vastness of the unknown.

  • While minuscule in scale, you.can still explore and learn.
    • What you discover could bridge that gap in scale.
      • Great distances have been traversed in time.

How far we go as a species depends on personal and societal motivation.

  • We have accomplished a great deal in a short amount of time
    • Where we go depends on how effective we can be.
      • Our issues in equality must be fixed first.
