A old video, but very effective if you have the patience to understand it. [ame=http://www.youtube.com/watch?v=iHzeGke6KdI&feature=channel_video_title]YouTube - Our View Of The Universe[/ame]
I find it especially effective because of it's conceptual depiction of time and space as a single dimension.
And matter too? A part of the single dimension??? Yes, please! I love it, every time I hear people (especially on the science channel) talk about how space and time are bent, and I just can go, "Ha! In your dreams!"
