And now the expansion is accelerating

They had to explain what is causing the acceleration so they invented dark energy. Makes you wonder what will stop the acceleration other than the speed limit.Will the universe run out of dark energy before it reaches the speed of light?

Another thing I don't understand is if the balloon model is correct, and space is expanding, then we are moving away from the objects at the edge of the observable universe in the other direction. We are moving away from the point where it started, when when we were "next" to these distant galaxies.

So wouldn't those objects at 13B lt yrs only have traveled half that distance in half the time?

    - By persistent I assume you mean we have never seen one of them stop functioning. - FrankC - 11/27/2012 9:27:30 PM
      - Then your theory states that the mass hangs around inside the black hole for a while... - alcaray - 11/27/2012 10:43:48 PM
        
        Not necessarily - FrankC - 11/28/2012 1:52:15 AM
        
        If the mass immediately goes there, then the mass immediately is not here. - alcaray - 11/28/2012 2:40:45 AM
        
        So after a black hole is formed, what happens to the additional mass it consumes? - FrankC - 11/28/2012 3:08:10 AM
        
        It's mass, demonstrably, is here. The effects of its mass are apparent. - alcaray - 11/28/2012 5:17:49 AM

        You don't need to hold a picture of a hypersphere in your head. - alcaray - 11/27/2012 4:14:52 AM
        
        Inflation and Expansion are not the same thing. - ER - 11/27/2012 5:43:42 AM

    - You are certainly correct, especially with "may". - bowser - 11/26/2012 8:39:42 PM
      - I don't think there is an "outside". - ER - 11/27/2012 1:26:45 AM
