**Can thermal input from a prior universe account for relic graviton production?:
Implications for the cosmological landscape**

**Abstract:**

The author presents how answering Sean Carroll’s supposition of a pre inflation state of low temperature-low
entropy pre inflation state provides a bridge between two models with radically different predictions. I.e. Loop
quantum gravity may be giving us a template as to thermal input which answers in the affirmative if or not relic
graviton production can exist. Brane world models as constructed by Randall and Sundrum permit the low entropy
conditions Carroll and Chen predicted in 2005, and then of course how to go from the brane world model so outlined
to the 10 to the 32 Kelvin conditions stated by Weinberg in 1972 as necessary for quantum gravity . Afterwards,
we would have a transition to Guth style inflation. This is also a way of getting around the fact that cosmological
CMB is limited by a red shift limit of about z = 1000. It also allows quintessence scalar fields of a very short
term time scale on the order of Planck time magnitude which allows for relic graviton production and leads to
dark matter/dark energy values predicted via current Chapyron joint dark matter/dark energy models after Guth
style chaotic inflation. We also discuss a difference in values of the upper bound of the cosmological constant
between a huge upper bound predicated upon temperature, and the much lower bound predicted by Barvinsky et al in
late 2006 with the difference in values an energy input into relic graviton production. Among other things, this
difference in Planck’s constant values accounts for how to introduce quantization via a shift in values of the
Hartle-Hawking wave function from a lower value of nearly zero to one which is set via an upper bound of the
Planck’s constant of the order of 360 times the square of the Planck’s mass.
