A closed universe whose energy density is dominated by matter will one day recollapse. ❋ Unknown (2010)
¦ A few of the little bubbles, however, will grow to a certain size at which they are safe from recollapse. ❋ Unknown (2007)
Note also that in the extended stage each black hole may be causally disconnected from any others, so no observer at any given location seeing a neighbouring hole come back into view as the recollapse got underway could be sure that this hole had always been in the same cosmos! ❋ Sean (2008)
This is typically a reference to the question of whether the universe will recollapse, forcing all its contents into smaller and smaller volumes, increasing the pressure and the temperature, or whether it will expand forever, gradually cooling to ever lower extremes of temperature. ❋ Mark (2008)
Third, though each recollapse would destroy the components of the universe, the radiation would remain, so that each successive cycle would add to the total. ❋ Reichenbach, Bruce (2008)
Einstein and Wheeler believed that the universe was closed and would someday recollapse, because a universe that was finite in time felt right to them. ❋ Sean (2008)
A popular model of the FRW cosmology was a recollapse model, which is similar to ballistic flight. ❋ Sean (2007)
This will then be the final state of the universe, as it appears recollapse does not happen, which occurs as time — infinity. ❋ Sean (2007)
If there was a negative cosmological constant, then the universe would recollapse in on itself. ❋ Sean (2007)
Apparently life is possible only because the universe is expanding at just the rate required to avoid recollapse. ❋ Plantinga, Alvin (2007)
A second question was a standard one I get in public lectures, although these students seemed to have more background than the general public, - “We know that the universe is expanding; do we know if it is infinite in size or not, and whether it will expand forever or eventually recollapse?” ❋ Mark (2007)
Hawking writes: Why did the universe start out with so nearly the critical rate of expansion that separates models that recollapse from those that go on expanding forever, that even now, 10 thousand million years later, it is still expanding at nearly the critical rate? ❋ Francis S. Collins (2006)
We can have positively curved universes that expand forever, negatively curved ones that recollapse, or what have you. ❋ Sean (2006)
If we take current observations at face value, and make the economical assumption that the dark energy is strictly constant in density, all indications are that the universe is going to expand forever, never to recollapse. ❋ Sean (2006)
(Not to mention that the universe shows no sign of wanting to recollapse.) ❋ Sean (2006)
We removed the dirt on the individual and we put it in areas so it will not recollapse on the individual. ❋ Unknown (2002)
There is no apparent danger of recollapse evident in any of the data for the end of the metasimulation period. ❋ Allen, Roger MacBride (1996)
It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. ❋ Unknown (2010)
Black holes are the one kind of clump that will _not_ evaporate in a hot radiation bath [new suggested advertising slogan: “Black holes — they plump when you cook ‘em!”] and so their high entropy will be preserved, and only increase, during all stages of the recollapse. ❋ Sean (2007)
