Toward a Phenomenologically Acceptable Quantum Cyclic Universe
Sean M. Carroll, Nadiia Diachenko, Saakshi Dulani
We put forward a quantum model of cosmology that is exactly periodic but avoids the Boltzmann Brain problem. If the universe is described by a quantum state evolving unitarily in a…
What Hawking Radiation Looks Like as You Fall into a Black Hole
Christopher J. Shallue, Sean M. Carroll
We study the measurements of a freely falling Unruh-DeWitt particle detector near the horizon of a semiclassical Schwarzschild black hole. Our results show that the detector's resp…
Holographic phenomenology via overlapping degrees of freedom
Oliver Friedrich, ChunJun Cao, Sean M. Carroll +2
The holographic principle suggests that regions of space contain fewer physical degrees of freedom than would be implied by conventional quantum field theory. Meanwhile, in Hilbert…
The Cosmological Constant
Sean M. Carroll
This is a review of the physics and cosmology of the cosmological constant. Focusing on recent developments, I present a pedagogical overview of cosmology in the presence of a cosm…
Energy-Momentum Restrictions on the Creation of Gott Time Machines
Sean M. Carroll, Edward Farhi, Alan H. Guth +1
The discovery by Gott of a remarkably simple spacetime with closed timelike curves (CTC's) provides a tool for investigating how the creation of time machines is prevented in class…
