A new satellite could see shadow of extra dimensions

David Shiga over at New Scientists reports on a new satellite to be launched next year that could possibly detect theoretical dimensions beyond the common 3 we are familiar with.

The satellite might be able to detect the hint of the extra dimensions in the afterglow of the big bang. The afterglow is from the cosmic microwave background that describes the structure of the universe from about 370,000 years after the big bang. But hey what's a few hundred thousand years when you are talking about billions!

This is fascinating as the extra dimensions are key to string theory which is attempting to unify everything into a single theory of everything. 2007 looks to be an exciting year for science (as long as we can keep the politics at bay!) as the Large Hadron Collider is to go online by the end of the year and will provide our first real glimpse into the reality of string theory. If it proves out it will change everything and we will all have to face the fact that there just might be unlimited parallel universes!

Wow, this is wildly cool. What's next, gravity telephones into the parallel dimensions?

If this works out our *shadows* are going to be saying "HEY, I can see my shadow!"

Personally I am very afraid of my shadow! :)

This also begs the question:

If there is no satellite would anyone hear a shadow asking that question?
