Beyond the Dynamical Universe: Unifying Block Universe Physics and Time as Experienced

Theoretical physics and foundations of physics have not made much progress in the last few decades. Whether we are talking about unifying general relativity and quantum field theory (quantum gravity), explaining so-called dark energy and dark matter (cosmology), or the interpretation and implications of quantum mechanics and relativity, there is no consensus in sight. In addition, both enterprises are deeply... Read more →

Quantum Field Theory With No Zero-Point Energy. (arXiv:1803.05823v1 [hep-th])  hep-th updates on on 2018-3-17 4:45am GMT Authors: John R. Klauder Traditional quantum field theory can lead to enormous zero-point energy, which markedly disagrees with experiment. Unfortunately, this situation is built into conventional canonical quantization procedures. For identical classical theories, an alternative quantization procedure, called affine field quantization, leads to the... Read more →

On the Nature of Discrete Space-Time: The distance formula, relativistic time dilation and length contraction in discrete space-time. (arXiv:1803.03126v1 [physics.gen-ph])  gr-qc updates on on 2018-3-10 1:42am GMT Authors: David Crouse, Joseph Skufca In this work, the relativistic phenomena of Lorentz-Fitzgerald contraction and time dilation are derived using a modified distance formula that is appropriate for discrete space. This new distance formula... Read more →

Emergent gravity from relatively local Hamiltonians and a possible resolution of the black hole information puzzle. (arXiv:1803.00556v1 [hep-th])  hep-th updates on on 2018-3-02 1:31pm GMT Authors: Sung-Sik Lee In this paper, we study a possibility where gravity and time emerge from quantum matter. Within the Hilbert space of matter fields defined on a spatial manifold, we consider a sub-Hilbert space... Read more →
