It’s NOT a “small, small world”

when we “Hubble it.”

The bigness of the Universe

boggles the mind

when space telescopes report in…

For some numbers, use the DOOR.

   Our Milky Way is a galaxy of stars.

   Our Solar System is in this average-sized galaxy, maybe 1/3 the way to the far edge of this disk-shaped spiral of stars.

   In the SS, our Sun (an average-sized star), has 8 planets whirling around it.

   Earth is one of those.

 

   Now to the bigger picture.

.

   About 200,000,000,000 stars are in a galaxy¹.

   In our farthest (yet) visual detectable distance away (about 13,000,000,000 light years²), there are 200,000,000,000 galaxies.

   That means there are (within visual reach) 40,000,000,000,000,000,000,000 (or 40 billion trillion) stars.

   That’s a “4″ followed by 22 zeros.

.

   So…depending on where you “stand” when “looking at things,” it’s a “big, big, big world,” or a “Small, Small World” after all³.

   ¹ All the approximate numbers here are from Hugh Ross’s, Why the Universe Is the Way It Is (Baker, 2008. p.31). Since it’s estimated that there are 10 trillion stars in unobserved dwarf galaxies, adding those in, that would make 50 billion trillion stars in the observable universe. This information comes from the Hubble Space Scope was sent up in 2005 with scientists collecting light from a small region for a million seconds, the longest exposure (then) ever taken by a telescopic camera. Ross is an astrophysicist/evangelist who founded and heads Reasons To Believe [www.reasons.com]. We recommend this website.

   ² A light year is a unit of distance, the amount of time it takes for light to travel in one year. (It takes about 8.3 minutes for light to travel from the Sun to Earth.)
