Spacetime may emerge from a more fundamental reality. Figuring out how could unlock the most urgent goal in physics—a quantum theory of gravity
In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. Universe The universe (Latin: universus) is all of space and time and their ...
Does quantum chromodynamics depend on Minkowski spacetime? What is the theory of spacetime and black holes? Does space-time expand at light speed? What is the first postulate of special relativity? What is relativistic quantum mechanics? What is the displacement of space-time? Where does the spec...
The amount of dark energy in the Universe is appreciablylessthan we had previously thought, while the amount of dark-and-normal matter is appreciablygreaterthan we thought! Instead of a Universe made up of73%dark energy, the best post-Planck estimate puts it at just68-to-69%. Instead ...
general relativity says nothing about the "atoms" that make up spacetime but describes the dynamics of spacetime as if it were a "classical" object. Spacetime would therefore be a phenomenon "emerging" from more fundamental constituents, just as water is what we perceive of the mass of H2O mo...
Quantum reality has a reversible nature, so the entropy of the system is constant and therefore its description is an invariant. The space-time synchronization of events requires an intimate connection of space-time at the level of quantum reality, which is deduced from the theory of relativity ...
whereis the Littlewood-Paley projection ofto frequency magnitudes. Then, given a spacetime slab, we define the restrictions where the infimum is taken over all extensionsofto the Minkowski spacetime; similarly one defines The gap in the paper is as follows: it was implicitly assumed that one cou...
Minkowski’s spacetime must be altered to make it simpler. For this, we can translate the complexity of Minkowski’s spacetime into conventional geometrical space, which makes it easier to understand and solve for. This geometrical space is known as Euclidean space. ...
more clearly we would be better at finding an answer. We have made some progress in understanding how time behaves. For instance, we now know that one shouldn’t think about space and time in isolation, but there really is this thing called spacetime—space and time together forming one ...
