different??
Hi.
According to the latest analysis of WMAP image, "the universe is 13.7 billion years old (accurate to 1 percent), composed of 73 percent dark energy,
23 percent cold dark matter, and only 4 percent atoms, is currently expanding at the rate of 71 km/sec/Mpc (accurate to 5 percent), underwent episodes
of rapid expansion called inflation, and will expand forever." (quoted from
antwrp.gsfc.nasa.gov...)
From the analysis, the scientists concluded that the universe is flat, never ending (see below). However, they are unsure about the nature of dark
energy, and thus their conclusion is in question.
Jazzerman is right! Our science and technology aren't advance enough to find out what lies at the end, or if there is an end at all.
if there is a boundary (like "a wall" as Stuey 1221 described), then the further question would be : What lies behind the boundary?
Talking about the expansion of universe and its geometry, the scientists have proposed three possibilities: Open, Flat, and Curved and concluded it to
be flat, according to the latest data. Read more here
