If you’re thinking about buying something astronomy-related for your astronomy buff, I have some ideas for you. […]

The Great Thing About Life

… is that things never stay the same for long.
I’ve spent last week getting accommodating all of the changes life has recently thrown my way. I’ve been lucky because these changes have all been positive. I’m getting ready to move my entire life 1000 miles to the east. Illinois to be exact […]

Was that a Thursday? I tend to get a lot more done on Thursdays myself.

If I Saw Jesus’ Face In a Burrito

…I would still eat it.
I supoose I’ll let this article speak for itself:
It would mean our understanding of how the cosmos was born 14 billion years ago is seriously flawed. Astronomers would have redder faces than they’ve had since the beginning of the 20th century, when some scientists claimed they saw “canals” built by Martians […]

How To Weight the Entire Universe All At Once

It blows my mind sometimes to listen to a cosmologist talk. They make some pretty remarkable statements about the universe, and they do it with such certainty.
For example, we know how big the universe is, we know how many stars are in the universe, likewise the number of galaxies, we know what it’s made […]

How Do We Know the Universe is Flat?

One of the things you hear a lot in cosmology, particularly when discussing the amount of dark energy there must be, is that the geometry of the universe tells us a lot about what’s in it.
For example, in order to have a flat, accelerating universe, 70 percent of our universe must contain something like dark […]

Energy Is Not Conserved in an Expanding Universe

I know, I know, I can hear you all harumphing and spluttering all the way over here.
HarumphHarumph What you do mean, man!? Have you gone mad? Harumph, I say to you!
The fact is, there’s nothing in Newton’s physics that requires that energy be conserved. The idea that energy is neither created nor […]

More Annoying Hints About My Life Changes

Time to move on
This last year has been, without a doubt, one of the strangest in my life. Starting at about the time I posted my Hubble Deep Field video in September 2006, my life started a slow change that has culminated in these past weeks.
It’s so strange how events transpire, one can never […]

Some of Us Are More Different Than Most of Us

Oooh, a graph! There’s nothing like a graph to get your science juices flowing.
Most people enjoy being in the middle of the bell curve. Indeed, they expend an enormous amount of energy to make sure they are as smack-dab in the middle as they can get.
If they start to see themselves stand […]

How Do We Know Normal Matter Makes Up 5% of the Universe?

As I write this, I’m watching the Illinois/Ohio State game. Currently, the game is tied 14/14 and I am quite pleased. I mention this not because you may be a football fan but as a hint to where my new job is. One of these schools will be my new professional home.
Now, […]
