Since there is a dyer lack of topics regarding science on this forum i thought i would open one. This topics is about the universe and scientific theories.
Here are several interesting links i have picked up, some of which include videos.

The Elegant Universe and theories

Space

Technology

Note: Some of the above links contain videos and these videos require a quick time player to watch. This player can easily be downloaded free from the apple website. This player is multi-functional and can be used to upload downloaded data onto an i-pod or MP3 or to purchase songs, videos etc.


Enjoy the Topic !

this is good series. but I'v noticed that duering last dacade, Dr. Michio kaku has been used as a propoganda tool to make people fantasize about topics like multiverse, m theory, alien plnets and far future. his practical views about current world may have same effect as Samuel P. Huntington in long term, when he talks about topics like post singularity , post human, AI, and defining type 2 and type 3 civilizations.
