Verusamore Posted December 5, 2004 Share Posted December 5, 2004 Would I travel further-out or travel farther-in to find out ? How do we know that the objects that exist farther-in toward the original point of BB are new , when only one BB has occured . for example : I represent space being water . I represent a stone being an object . I drop the stone in the water ,the stone blows up as it reached a critical point,the water splashes and ripples expanding in an outwards motion pushing current water and creating a new type of water which exists in our known universe called 'dark energy' being the bond that glues our universe The particles & matter created from this stone expand with the water as the movement is exerted by the ever expanding dark energy . The final point of expansion is where the matter has travelled the furthest point ,does this typically mean that this matter is also the oldest ? Or is everything the same age as long as it exists within the reaches of dark energy ? Link to comment Share on other sites More sharing options...
Verusamore Posted December 5, 2004 Author Share Posted December 5, 2004 Was there 1 BB then a series of other chain reactions of SB ( small-bangs ) ? How do we know that the original BB isn't a small-bang compared to a possibly greater one ? Link to comment Share on other sites More sharing options...
Verusamore Posted December 5, 2004 Author Share Posted December 5, 2004 If Earth is said to be 4.5 billion years old and the universe being 13.* then how is earth younger than the total age of the universe when only one known big bang has caused all matter that exists within our universe to age differently . Or unless Was there 1 BB then a series of other chain reactions of SB ( small-bangs ) ? Or the the original BB is a smaller-bang compared to a possibly greater one ?

swansont Posted December 5, 2004 Share Posted December 5, 2004 If Earth is said to be 4.5 billion years old and the universe being 13.* then how is earth younger than the total age of the universe when only one known big bang has caused all matter that exists within our universe to age differently . The eartg is dated to ~4.5 billion years because that's the age of the matter in that form. Before that it was supernova leftovers that eventually coelesced. Before that it was part of a star, and prior to that a different star, in the form of hydrogen. It's not that things aged differently. You are measuring to different starting points.

Verusamore Posted December 5, 2004 Author Share Posted December 5, 2004 Yeah that was what I was thinking . You are measuring to different starting points. Link to comment Share on other sites More sharing options...
RawThinkTank Posted December 9, 2004 Share Posted December 9, 2004 we dont. The distant objects that we see 13 billion light years back; It must have took them trillions of years to reach there from the center of the universe. Link to comment Share on other sites More sharing options...
Severian Posted December 9, 2004 Share Posted December 9, 2004 WMAP has given us the best estimates for the age of the universe so far. Take a look here: http://map.gsfc.nasa.gov/m_uni/uni_101age.html Link to comment Share on other sites More sharing options...
MOTP Posted December 12, 2004 Share Posted December 12, 2004 How do we know the universe had a beginning? Link to comment Share on other sites More sharing options...
