Where to find information about VRML? Here are two sites you may want to visit:

1. The VRML Repository
   It is the best site to find a VRML 2.0 Plug-in for your browser: The VRML Browsers or Plug-in's

2. VRUNIVERSE

• Black Hole, Worm Hole and Universe (Physics/Gravitation)
  Warning: You must have installed VRML 2.0 Plug-in

  According to Eistein's general relativity, a gravitational filed is just a curved 4D space-time caused by the existing matter. A black hole is a very dense object with such a deep twisted space that is looks like a funnel in a 3D space-time. Two black holes may form a worm hole. I always wonder what if the two black holes belong to different Universes? Here are two static models for you to play with. In our animated model of the Universe, there is a standing wave, whose wave length is increasing (red-shift) when the Universe is expanding, decreasing (blue-shift) if the Universe is collapsing. Because we do see the red-shift, our Universe is expanding. Note the size of black holes (and galaxies) does not change with the universe. It is not sure whether our Universe will be collapsing in the future, because it depends on if the average mass desity of our Universe is greater than a critical value, and scientists are still looking for the dark matter...And if there are other universes connected with ours through worm hols?
