Living in "Eden" and You Didn't Even Know It

Whenever I need a reminder of how blessed we are and how amazing creation is, I just think about the frigid, inky blackness of space that just beyond the atmosphere of our swirling, blue marble of a world.

Many times we take our Earthly "home" for granted and complain about the weather, especially when it is "too cold outside". The next time you feel like complaining, consider this:

The temperature of the Universe is 2.726 kelvin

This is equal to -270.424 degrees Celsius. That...is seriously cold!

0 kelvin (-273.15 degrees Celsius) is also called "absolute zero"

"Absolute zero is a temperature marked by a 0 entropy configuration. It is the coldest temperature theoretically possible and cannot be reached by artificial or natural means. At absolute zero all molecular motion does not cease but does not have enough energy for transference to other systems." [1]

"Outer space is an extremely hostile place. If you were to step outside a spacecraft such as the International Space Station, or onto a world with little or no atmosphere, such as the moon or Mars, and you weren't wearing a space suit, here's what would happen:" [2]
  • You would become unconscious within 15 seconds because there's no oxygen.
  • Your blood and body fluids would boil and then freeze because there is little or no air pressure.
  • Your tissues (skin, heart, other internal organs) would expand because of the boiling fluids.
Sound like fun?

The coldest natural temperature ever recorded on Earth was −89.2°C (−128.6°F) at the Russian Vostok Station in Antarctica July 21, 1983. [3]

I have been outside in Minnesota when it was -30°F (with no wind chill) and -90°F with a wind chill. Cold enough for me, thank you. Wouldn't personally want to experience -128.6°F.

But considering the Universe next door, the coldest temperature recorded on Earth was a balmy 181.2 degrees warmer.

Compared to the Universe you truly do live in a relative "Garden of Eden". Isn't that nothing short of amazing!? Here is the good news.... it is going to get EVEN BETTER!
