Freaky Fzx Friday - The Birth of the Universe

Last week we took a look at some pictures of planets and stars to get some idea of how tiny we are. but we didn't even talk about our galaxy.

The Milky Way.  La Via Lactea.

The same light that takes 8 minutes to get here from our sun takes 100,000 years to cross the Milky Way.  It's 100,000 light years across and we are 8 light minutes from our sun.  The galaxy's big and we're in a peaceful part of it.

sun not to scale

The closest galaxy to ours is Andromeda.  It's 2.5 million light years away.  Wanna know what was happening 2.5 million years ago?  Just look at Andromeda.  It looks like a star in our sky but it's 220,000 light years across.

And there are just as many galaxies as there are stars in each galaxy.  It's crazy.

Anyway, in celebration of birth week, let's go back in time.

But let's be honest.  It's the best explanation we have and it's pretty well established but there are a lot of details we don't know yet.  We're filling in those details as time goes on but more and more questions keep popping up.  It's the nature of science.

I was there for the births of our three children.  I cried at every one.
