Can we travel to the past? Irreversible physics along closed timelike curves
Carlo Rovelli
The Einstein equations allow solutions containing closed timelike curves. These have generated much puzzlement and suspicion that they could imply paradoxes. I show that puzzlement…
ESA Voyage 2050 white paper -- GrailQuest: hunting for Atoms of Space and Time hidden in the wrinkle of Space-Time
L. Burderi, A. Sanna, T. Di Salvo +30
GrailQuest (Gamma Ray Astronomy International Laboratory for QUantum Exploration of Space-Time) is a mission concept based on a constellation (hundreds/thousands) of nano/micro/sma…
Neither Presentism nor Eternalism
Carlo Rovelli
Is reality three-dimensional and becoming real (Presentism), or is reality four-dimensional and becoming illusory (Eternalism)? Both options raise difficulties. I argue that we do…
On the statistical mechanics of life: Schrödinger revisited
Kate Jeffery, Robert Pollack, Carlo Rovelli
We study the statistical underpinnings of life. We question some common assumptions about the thermodynamics of life and illustrate how, contrary to widespread belief, even in a cl…
Minisuperspace model of compact phase space gravity
Danilo Artigas Guimarey, Jakub Mielczarek, Carlo Rovelli
The kinematical phase space of classical gravitational field is flat (affine) and unbounded. Because of this, field variables may tend to infinity leading to appearance of singular…
Reflections on the Energy of Black Holes
Tevian Dray, Carlo Rovelli
Inside a black hole, there is no local way to say which side of a sphere is the inside, and which is the outside. One can easily be gulled by this fact into mixing up the sign of t…
