In this article we derive the second order Friedmann equations from the QRE, and show that this also contains a couple of quantum correction terms, the first of which can be interpreted as cosmological constant (and gives a correct estimate of its observed value), while the second as a radiation term in the early universe, which gets rid of the big-bang singularity and…</p><p><a href="https://hackerpaper.kaipfister.de/p/1404.3093/">Paper and discussion history</a>.
