For example, the unification of electricity and magnetism, and weak and electromagnetic forces. To continue this reductionism, we want a theory that unifies all known forces.

Past attempts for a theory of everything include string theory and loop quantum gravity. But string theory does not produce any falsifiable results. Its mathematics is too flexible. Loop quantum gravity only addresses gravity and not the other forces. Quantum Holonomy Theory or QHT was pioneered by two Danish scientists, physicist Jesper Grimstrup and mathematician Johannes Aastrup. It begins by asking question, how can a theory be immune to further scientific reductions, so that reductionism ends? The presumptive idea is that the simplest way to describe the universe is objects moving around in three dimensional space. The theory is based on the mathematics of empty 3-dimensional space, just space, not even time. So the starting point of QHT is the mathematics of moving stuff around. There are an infinite many ways you can move an arbitrary object between points in space. Any one of these combination of movements from point A to point B, is called a recipe. A recipe for a combination of movements in physics is called a gauge field. A gauge field is the recipe of how to move one particle from point A to point B. Gauge fields are what makes up the forces in the standard model. Since they are recipes of moving things around in space, they represent how things interact with each other, or how forces work. The sum of all mathematical recipes is called the “Configuration space” of these recipes. The key insight in QHT is that the this space has a geometry and stores a lot of information. Geometry means that two different recipes for moving stuff around can be said have a relationship between each other. This is complicated but can be proven mathematically. Grimstrup and Aastrup found is that this geometry results in mathematics that looks almost identical to the mathematics that we already know from quantum field theory – this includes the mathematics of the Standard model. From the geometry you can obtain a a Bott-Dirac operator. The square of this operator gives us the Hamiltonian for both matter particles and force carrying particles. The Hamiltonian represents the formula for all the energy in a system. #QHT #Theoryofeverything Once you have a description of the energies of all the matter and forces in the universe, that’s all you need to need to understand how matter interacts in the universe, and is essentially everything we would need to describe the universe, once all the math is worked out. By simply considering the movements of objects in empty space, all this rich mathematics that appears to resemble the known mathematics of the universe comes out. If QHT is correct, then here are the implications: 1) The universe is quantum because the only way you can describe things moving in empty space is via quantization. 2) Gravity is not quantized, so there is no theory of quantum gravity. 3) No singularities can exist 4) There is no infinite curvature of space-time inside black holes 5) The universe could not have come from nothing, but from a prior universe — a Big Bounce!

Supermassive Black Hole Heading Towards The Milky Way Galaxy

Back in 1971, a couple of British astronomers predicted the existence of a black hole at the center of our galaxy. And in 1974, other astronomers found it, naming it Sagittarius A*.

Since then, astronomers have discovered that a similar “supermassive black hole” sits at the center of almost every other large galaxy. In 2019, they took the first image of a supermassive black hole. Today, these exotic objects are a fundamental part of our understanding of how galaxies form and evolve.

But what of smaller astronomical bodies, like the Large Magellanic Cloud, a dwarf satellite galaxy that is expected to collide with the Milky Way in 2.4 billion years? Nobody is quite sure whether clouds like this might also house supermassive black holes.

Runaway stars reveal hidden black hole in Milky Way’s nearest neighbor

Astronomers have discovered strong evidence for the closest supermassive black hole outside of the Milky Way galaxy. This giant black hole is located in the Large Magellanic Cloud, one of the nearest galactic neighbors to our own.

To make this discovery, researchers traced the paths with ultra-fine precision of 21 stars on the outskirts of the Milky Way. These stars are traveling so fast that they will escape the gravitational clutches of the Milky Way or any nearby galaxy. Astronomers refer to these as “” stars.

Similar to how recreate the origin of a bullet based on its trajectory, researchers determined where these come from. They found that about half are linked to the at the center of the Milky Way. However, the other half originated from somewhere else: a previously-unknown giant black hole in the Large Magellanic Cloud (LMC).

Wolfram’s Theory of Everything: The Universe Is a Giant Computer

In human engineering, we design systems to be predictable and controlled. By contrast, nature thrives on systems where simple rules generate rich, emergent complexity. The computational nature of the universe explains how simplicity can generate the complexity we see in natural phenomena. Imagine being able to understand everything about the universe and solve all its mysteries by a computational approach that uses very simple rules. Instead of being limited to mathematical equations, using very basic computational rules, we might be able to figure out and describe everything in the universe, like what happened at the very beginning? What is energy? What’s the nature of dark matter? Is traveling faster than light possible? What is consciousness? Is there free will? How can we unify different theories of physics into one ultimate theory of everything?

This paradigm goes against the traditional notion that complexity in nature must arise from complicated origins. It claims that simplicity in fundamental rules can produce astonishing complexity in behavior. Entering the Wolfram’s physics project: The computational universe!

ALPHA experiment successfully installs helium dilution fridge to aid search for dark matter

The Axion Longitudinal Plasma Haloscope (ALPHA) experiment reached a milestone on February 24 with the successful installation of a Bluefors helium dilution fridge at the site of the experiment in Wright Lab.

ALPHA will extend the search for a hypothetical dark matter candidate—a very low-mass particle called the axion—to a higher mass range than has been searched for previously.

Michael Jewell, associate research scientist in physics and a member of Yale’s Wright Lab is the ALPHA project technical coordinator. Jewell explained, “In order for ALPHA to achieve its physics goal, we need to limit any potential source. For us, the biggest source of noise is thermal noise from the experiment. So we operate the whole experiment in the coldest commercially available systems, which are helium dilution fridges that are able to cool down to ~10 millikelvin (mK).”

Water might be older than we first thought, forming a key constituent of the first galaxies

Water may have first formed 100–200 million years after the Big Bang, according to a modeling paper published in Nature Astronomy. The authors suggest that the formation of water may have occurred in the universe earlier than previously thought and may have been a key constituent of the first galaxies.

Water is crucial for life as we know it, and its components—hydrogen and oxygen—are known to have formed in different ways. Lighter chemical elements such as hydrogen, helium and were forged in the Big Bang, but heavier elements, such as oxygen, are the result of nuclear reactions within or supernova explosions. As such, it is unclear when water began to form in the universe.

Researcher Daniel Whalen and colleagues utilized computer models of two supernovae—the first for a star 13 times the and the second for a star 200 times the mass of the sun—to analyze the products of these explosions. They found that 0.051 and 55 (where one solar mass is the mass of our sun) of oxygen were created in the first and second , respectively, due to the very high temperatures and densities reached.
