A FB comment just reminded me my head was totally blown yesterday in cosmology.

When I teach Astro 101 I tell my students that we know about the Big Bang because we see that things are moving apart from each other right now, so this means they once had to be closer together in the past. Kinda like if we're watching a fireworks show, and we look away for a moment and turn back to see a firework after it's already exploded. We see the glowing bits moving apart from each other, and we know that perviously they all came from a big explosion. That's just like the Big Bang.

Turns out I'm wrong.

The rest of this post is based around two graphs, one which I already knew about and one which blew my mind. The text will extensively explain these graphs, hopefully sufficiently well for non-typically visioned people as well. Continue on if you want to learn some cosmo.

( Here's a graph I already knew about, with an explanation. )

( Here's the second graph which blew my mind, with an explanation. )

So yeah, that was my big HOLY SHIT moment yesterday, realizing what that "NO Big Bang" meant.

Hope you learned a bit of cosmo there. :)

One of my reading assignments last week was a Wikipedia article. Do you know how hard it was to resist editing the article?!?! I figured it would corrupt the learning process if I did so.

I was attending a wedding. The bride and groom were trying to rival T&J's wedding - instead of having someone sing one cortina, they were having two people sing cantinas. I was taking photos of the lip synch performance, and then got swept into the folk dance where Tom Cruise started flirting with me. There may have been gladiators too. I had to leave the party for something so *reality* I woke myself up and will now go to return the rental.

Man, I have so much homework to do.

I posted this as a comment to

amavia's post on class structure in the US, and thought it deserved space of its own.

Sometimes I am amazed by people's stories of different classes. My Nga Boo (maternal grandmother) was from a rich family in Shanghai. They had servants, wet-nurses (Ama), and "companions" (as my family calls them) - I think a companion is the child of the wet nurse who was born at roughly the same time as the family member.

She was a rebel though, she broke off an arranged marriage to marry a Cantonese peasant, who later was part of the Nationalist Army. He (my Nga Cone) borrowed an army buddy's passport which had permissions to come to the US, and somehow arranged for asslyum for my Nga Boo and infant mother. They took a boat here, my Nga Boo strapping my three-year-old mother to her back so that she wouldn't get washed overboard on the stormy journey. Once here, Nga Cone opened a resturaunt, Nga Boo waited tables, and Mom bussed the tables after school.

And at family reunions not only do I bow to my Boo-boo's (grand aunts), but also to one woman who was the companion of a Boo-boo. She never married: even here in America her main goal in life was to serve as my Boo-boo's companion. She could have left at any point in time, but she never did.
