Happy Yule, everybody!

Happy Yule! Or Christmas or Hanukkah or Saturnalia or Hanukkah or HumanLight or Kwanzaa or Festivus or whatever you might to celebrate around this time.

Yule is from the old-time Germanic name for celebrations at this time of year, a name that Scandinavians still use. I don’t have a Yule log to burn, but with the help of wiktionary.org, I’ve composed some proto-Germanic, spoken some 2000 – 2500 years ago in what is now northern Germany and southern Scandinavia:

Gôdan Yehulan! Gôdô sunnôn-standingô! Hampan allaimaz mannumaz — allaimaz gumammaz andi kwenômaz.

Good Yule! Good sun-standing (solstice). Happiness to all people — to all men and women.

Solstice: the word is a borrowing from Old French solstice, in turn from Latin solstitium, “sun-standing”

Why celebrate at this time of year? Because in the northern hemisphere, the Sun seems like it is returning from having gone southward. Why lights? Because light is what the northern hemisphere is short of. Why evergreen trees? Because they seem like they are still alive. The traditional song “O Tannenbaum” / “O Christmas Tree” celebrates how that tree does not seem to die, as many other trees seem to.

As I’d noted in <a href=”https://nexuszine.wordpress.com/2010/12/26/the-reason-for-the-season-7000-years-ago/&#8221; title=”The Reason for the Season 7000 Years Ago”>The Reason for the Season 7000 Years Ago</a>, people have been marking out the solstices for centuries before Jesus Christ was born, and centuries before the first record of his ethnicity.

The Fermi Paradox: Unwilling to Contact?

I come to my final major category of solutions, the hypothesis that interstellar-capable extraterrestrial civilizations are unwilling to make contact with us, or else that they are trying to hide from us and other civilizations. Not surprisingly, this category contains some “fun” hypotheses. Here are some:

  1. Lack of Interest in Contacting Others
  2. Hiding from Others
  3. We are Not Worth Contacting
  4. The Zoo Hypothesis

The Fermi Paradox: Too Hard to Contact? II

I will continue with the hypothesis that it is too difficult to make contact over interstellar distances.

  1. Interstellar communication is too difficult. I
  2. Interstellar travel is too difficult. I
  3. We have not been searching long enough.
  4. We have not been searching for the right kind of evidence.
  5. We already have evidence of ET’s, but we don’t recognize it.
  6. We already have evidence of ET’s, but we are unwilling to recognize it.

So with this post, I conclude my discussion of this possibility.

The Fermi Paradox: Too Hard to Contact?

I will now consider the hypothesis that interstellar-capable extraterrestrial civilizations are common, but that it is difficult or impossible for us to contact them or for them to contact us.

  1. Interstellar communication is too difficult.
  2. Interstellar travel is too difficult.
  3. We have not been searching long enough.
  4. We have not been searching for the right kind of evidence.
  5. We already have evidence of ET’s, but we don’t recognize it.
  6. We already have evidence of ET’s, but we are unwilling to recognize it.

I will leave off at interstellar-travel difficulty.

The Fermi Paradox: Too Rare? IV

I have completed this list:

  1. Stars I
  2. Planets I
  3. Origin of Life I
  4. Origin of Photosynthesis II
  5. Multicellularity II
  6. Colonization of Land II
  7. Intelligence III
  8. Technology III
  9. Abstract Science III

There is an additional set of issues that I wish to discuss before I turn to other Fermi-paradox solutions.

  1. Natural Disasters
  2. Self-Destruction

So after looking at all these factors, I conclude that there are numerous possible bottlenecks that can prevent the emergence of a long-lived technological civilization, and numerous possible calamities that have been nicknamed “The Great Filter”. So rarity is very hard to rule out.

The Fermi Paradox: Too Rare? III

In my previous post, I had discussed this list up to the colonization of land.

  1. Stars I
  2. Planets I
  3. Origin of Life I
  4. Origin of Photosynthesis II
  5. Multicellularity II
  6. Colonization of Land II
  7. Intelligence
  8. Technology
  9. Abstract Science

I will be finishing off this list.

Here, I’ll be doing up to colonization of land.
