… to the prediction we have emphasized: a small, positive cosmological constant. Four
features inherent to the cyclic model play a key role in rendering the combined model viable. …

… in favour of such an increase, but is much too imperfect to be able to assert that such an
increase cannot occur, as it is so small ; so there is no need to condemn our theory on this …

… Long-distance (infrared) modifications are unhelpful because we know that the universe
started out small, and the cosmological constant problem is the prediction that the horizon …

… the cosmological constant corresponds to a very tiny vacuum energy density. We discuss
future observational tests for a cosmological constant … if the Hubble constant is extremely small, …

… 1 TeV, this is still 60 orders of magnitude too high. Until recently, this discrepancy between …
only cosmological constant problem. Its solution, many believed, was that something so small …

… If we discount the possibility that the vanishingly small value of the cosmological constant
is accidental, we must accept that it has profound implications for physics. Before we launch …

… cosmological constant and –x the amplitude and shape of the primordial power spectrum
in accordance with data on cosmic … V on the cosmological constant indicates that the small, …

… we choose this arbitrary constant so that the minimum of V is … We know that no simple
low-energy theory is likely to be … and possibly from a bare cosmological constant itself. Each of …

… But it is necessary to the situation that I hav described, in that the small scale value of the
cosmological constant is negative because bubbles always add a positive contribution to the …

… The old cosmological constant problem is to understand why the vacuum energy is so small…
the anthropic principle may apply to the cosmological constant, but probably to nothing else. …
