Howling:What is a "universe"?

I was looking at some things on the wikia and I wasn't sure about the correct definitions of things when it comes to parallel universes and alternate dimensions and timelines. What is a universe and what is a dimension, since it seems that they are used interchangibly. What are your thoughts on these definitions? Steed 20:30, May 18, 2010 (UTC)


 * The two articles Alternate timeline and Parallel universe are fairly instructive and interesting. Dimension also gives a breakdown of what it is. --Tangerineduel 05:21, May 19, 2010 (UTC)
 * It seems rather straight forward to me. A parrallel universe is exactly that, an entire universe that is different to the one in which we occupy. An alternate dimension may refer to the same thing (ie the parrallel universe is in an alternate dimension to our own) however it doesn't need to be an entire universe. For a recent example, look at Rory's comments when he enters the TARDIS in which he says the inside of the TARDIS is another dimension which the doctor is unhappy about as he prefers people to say "It's bigger on the inside". The outside of the TARDIS occupies our dimension whilst the inside is in a different dimension allowing it to contain more space that the physical limitations imposed by the outside. It also allows it to be picked up and moved around on a number of occasions!

 * A change in a timeline within one universe affects that universe and changes the current state of it. That universe is now on an alternate path to what it once was. There can still be a parrallel universe that was the same or similar to the universe that was alterered by changing the timeline. I haven't read the definitions but if they are confusing to you or contain errors maybe you should make some adjustments? R Breed 116.193.194.166 05:58, May 19, 2010 (UTC)
