That, most probably, this effect is now observed in many room-temperatureĮther-drift experiments and, in particular, in a very precise cryogenicĮxperiment where this level of signal is about 100 times larger than theĭesigned short-term stability. I describe several broad features of a programme to understand gravity as an emergent, long wavelength, phenomenon (like elasticity) and discuss one concrete framework for realizing this paradigm in the backdrop of several recent results. In this essay we marshal evidence suggesting that Einstein gravity may be an emergent phenomenon, one that is not fundamental'' but rather is an almost automatic low-energy long-distance consequence of a wide class of theories. Should exhibit a tiny fractional anisotropy at the level 10^. One of the hottest new ideas in physics is that gravity is an emergent phenomena that it somehow arises from the complex interaction of simpler things. Transformations and, for an apparatus placed on the Earth's surface, light We study the effect of this extra contribution on the emergent laws of gravity, and argue that it leads to a modification compared to Einstein gravity. Would not coincide exactly with the basic parameter "c" entering Lorentz In this case the speed of light in the vacuum There is sufficient internal evidence for this in the structure of classical gravitational theories. Classical Gravity has the same conceptual status as elasticity/hydrodynamics. Padmanabhan IUCAA, Pune, INDIA Classical Gravity has the same conceptual status as elasticity/hydrodynamics. Einstein’s genius was in realizing that this particular feature requires an explanation and then developing a theoretical framework (‘gravity is curvature of spacetime’) in which it emerges naturally. Pluchino Download PDF Abstract: According to some authors, gravity might be an emergent phenomenon in aįundamentally flat space-time. GRAVITY AS AN EMERGENT PHENOMENON: STATUS AND PROSPECTS T. General theory of relativity (or Lovelock extensions) is a dynamical theory given an initial configuration on a spacelike hypersurface.
