God doesn’t just roll dice, the vast casino of quantum physics may have more rooms than we think. In fact, there are countless more.
Physicists from the University of California, Davis (UCD), Los Alamos National Laboratory, and Ecole Polytechnique Fédérale de Lausanne in Switzerland have redrawn the map of fundamental reality to demonstrate that the way we relate objects in physics can hinder Let’s look at the bigger picture.
For about a century, theories and observations under the banner of quantum mechanics have complicated our understanding of reality. Gone are the days when objects had absolute measurements such as velocity and position.
In order to understand the structures that make up the universe, we need mathematics to break down games of chance into possible measurements.
This is far from an intuitive cosmology. In what came to be known as the Copenhagen interpretation of quantum physics, there seemed to be waves of possibilities, until there weren’t. Even now, we still don’t know what ultimately sealed the fate of Schrödinger’s cat.
That hasn’t stopped physicists from considering the options. American physicist Hugh Everett argued in the 1950s that all possible measures constitute their own reality. What’s special about this is just that you happen to be observing it.
Everett’s “many worlds” model is less a theory than a way of rooting the sheer weirdness of quantum mechanics in something tangible.
We start with an impression of a possible infinite multiverse, or what a physicist might call the sum of all energies and locations called the global Hamiltonian, and then zoom in on what we’re interested in, limiting the infinite to the finite and more In the range.
However, does this “amplification” hinder us as a means of understanding the infinite? Or, as the researchers behind this latest study describe it, is this approach “too narrow, stemming from our familiarity with certain macroscopic objects?”
In other words, we might easily ask whether Schrödinger’s cat is dead or alive in the box, but not consider whether the table below is hot or cold, or whether the box is starting to stink.
To determine whether our tendency to focus on the inside of a box matters, the researchers developed an algorithm to consider whether some quantum possibilities, called pointer states, might be more stubbornly set than others, thus Make some key attributes less important.
If so, the box describing Schrödinger’s Cat is in some way incomplete Unless we’re considering a long list of factors that might extend to the entire universe.
Arsalan Adil, a physicist at University College Dublin, explained to Karmela Padavic-Callaghan: “You can put the Earth and part of the Andromeda Galaxy in a subsystem, and it’s a perfectly legal subsystem. ” new scientists.
In theory, there are no restrictions on how subsystems can be defined, and adding long lists of near and far states can isolate reality in subtly different ways.
Starting with Everett’s “many worlds,” the team proposed what they call a “many worlds” explanation, multiplying an infinite set of possibilities with an infinite range of realities that we don’t usually consider.
Much like the original explanation, the novel is less a commentary on the behavior of the universe and more about our attempts to study it a little at a time.
The researchers stress that their algorithm doesn’t lend much conceptual meaning, but they do wonder whether it could be applied to developing better ways of probing quantum systems, such as those inside computers.
No doubt in other realities they already have the answer.
The research, which has not yet been peer-reviewed, is available on arXiv.
