• expanding and continuing getting bigger all the time.
  o
• most distant galaxies rush outwards in all directions – moving away from us at about 90% of the speed of light.
  o
• recent theories suggest that our Universe may just be one of countless bubbles of space-time – multiverses shows a cluster of interesting universes that happens to be neighbours. (See BizleyArt)
  o
• no maximum possible temperature in the Universe.
  o
• accurate minimum possible temperature of -273ºc.
  o
• working in specialised laboratories, they cannot achieve this ultimate low temperature than -273ºc.
  o
• matter is not spread out evenly throughout the Universe.
  o
• on the largest-scale, the Universe lies up of thin filaments (fibre), each one made of millions of galaxies that surround huge empty space that contain nothing but clouds of hydrogen (gas) between galaxies.
