Stephen Hawking is giving this year’s Reith Lectures all about Black Holes. I found this video somewhere and thought you might enjoy it if you are interested in Space. . I think the animation helps!

Over the week I have had some great contributions which might be found in the comments but I thought I would group a few of them here to make it easier! The first to mention is now a menu item above. Under Fun Stuff you should see Scale Of The Universe. It is an amazing …

SpaceX…
The SpaceX vehicle Falcon 9 has just delivered an important satellite into orbit. It is an unusual space vehicle in that the initial rocket stage is designed to be reuseable. It is meant to land back on a brage in the middle of the ocean. It doesn’t always work!
He’s Done It…
I wrote about Felix here and now he has done it. You can follow the whole story at the Guardian’s website.
Dark Matter and Dark Energy…
a post by Dreamy One aspect of the Universe’s expansion was quite certain in the early 1990s.

Clear Explanation…
It is lovely when something is explained in such a way that the ‘light bulb’ goes on inside and one suddenly realises the point of the subject being explained. I teach for a living, but it is still relatively rare that I am sure that such an event has occurred. I often get asked about E=mc2. …
