What Makes Up The Universe?

“The cosmos is all that is or ever was or ever will be. Our feeblest contemplations of the Cosmos stir usthere is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, or falling from a height. We know we are approaching the greatest of mysteries.” –Carl Sagan

One of the greatest things we can do — when we study and learn the story of the Universe — is simply to tell that story, as best as modern science allows us to. Earlier this week, I had a chance to do this in front of a small, intimate audience at the Hand-Eye Supply Curiosity Club here in Portland, OR. Here’s a video of the entire talk — complete with Q&A at the end — for your enjoyment.

I hope you like it!

    Although I’m sure they exist in your sundry postings, would it be possible to add the various slides/pictures to a file to accompany this lecture? The slides are kinda washed out in the video. Thanks

    Unfortunately, the amount of effort it takes to translate a talk into a good blog post is far greater than the amount it would take to simply write a good blog post.

    The talk exists as-is, and I’ll be happy — whenever I give a talk that is recorded and shared publicly with better audio/video — to post that as well, of any-and-all of my talks. Sorry that the quality isn’t better!

    I thought it was kinda funny that I could visualize all the graphs and pictures you were using, from reading your blog. =D

    For the Hubble Deep Field one I just turned around and looked at my wall. Favorite. Astronomy. Picture. Ever.

    Can you also make the slides available? A little hard to see them in the video.
