And just to follow up on those roughly half-million ancestors from 500 years ago: that's actually half a million positions on the family tree, not half a million individuals.  It's statistically certain that individuals occupied multiple positions in my ancestry, and probably even across multiple generations.

Of course, to throw a little further perspective on this, I can do no better than to quote Robert Anton Wilson:

Quote
Most of our ancestors were not perfect ladies and gentlemen. The majority of them weren't even mammals.

According to this:

http://bigthink.com/paul-ratner/how-many-people-have-ever-lived-on-planet-earth

There have been 108.2 billion people that have lived on Earth. That's a lot of ancestors, considering I have no idea who either of my parents were!

Your genes know, approximately, who your biological parents were.  But the really important parents are the one's who raise you.

There's a term for the phenomenon of finding a single person in multiple places in your ancestry: Pedigree collapse.

And it's something we all have -- that we must have, in fact, since it's not possible to have more distinct ancestors than there were/are total people that have ever lived.

Parallel to that, if you're European or of recent European stock, you're descended from Charlemagne.  Congratulations, Your Highness.  :)

More recently, King Charles II of GB really got around a lot ;-)  Most US Presidents are descended from him.  Obama is a cousin of Cheney.  Inbreeding.

Well, I was adopted when I was 3, then those folks got divorced when I was 10, and I went to a boy's camp for a couple of years. Then I went to a foster home for four years, then I was in an orphanage for a couple of years, then got in trouble with the law and was "encouraged" to join the service when I was 17.


So, who raised me?

It could even be the favorite authors/characters you read before you were 21.  Have any real or fictional heroes you take after?  My situation was more stable, so I was able to imprint off my adoptive parents (their good points only).  But I have had many real and fictional heroes, because of all I have read.  I am still growing ... over 12 feet tall now.

I didn't spend much time reading in those days. So no idols, no heroes, role models. It was purely an act of self-creation.

Sorry, but psychotic individualism ... isn't a good thing.  I am sure you took after some musicians, movie stars or sports stars.  Are you sure you weren't kept locked in a basement for 40 years and dreamt the rest of it?

The whole idea of the comoving distance to the edge of the universe hurts my brain.  But it's a good kind of hurt, like chiles.  Those quasars 13 billion light years away are actually 46 billion light years because space has expanded since then.  Ow.  Mentally yummy, but ow.

Even worse, THOSE quasars have the same distance on the other side from us.  And so to those.

When "they" say the universe is 13 billion years old, they only mean the part we can see.  It logically spreads further.

You have to get into projective geometry ... weirder than Riemannian geometry (of GR).  In higher math, you can't visualize, you have to make up a symbolic game, and play out the game.  Like tick-tac-toe with yourself, all legal moves being allowed.
