Unifying physics’ biggest divide: Equation links Einstein’s relativity, quantum mechanics

A modified version of Einstein’s general relativity equation reveals the strange connection between gravity and entropy.




Several physicists have proposed theories that try to unite quantum mechanics with Einstein’s general theory of relativity. But a new study goes one step ahead; it not only links the two theories but also suggests that gravity emerges from quantum entropy.

The study author, Ginestra Bianconi, who is a physicist and a professor of applied mathematics at the Queen Mary University of London, proposes that “gravity is derived from an entropic action coupling matter fields with geometry.”

In simple words, this means that gravity is not a fundamental force by itself but instead comes from the way matter interacts with the shape (geometry) of space. This interaction is driven by entropy, which is a measure of disorder in a system. This indirectly suggests that a lack of entropy growth might cause gravitational effects to diminish, leading to unpredictable consequences for our universe.
 
Connecting quantum entropy and gravity

Physicists have long attempted to find a single theory that unites quantum mechanics and general relativity. This has been very tricky because quantum mechanics focuses on the unpredictable nature of particles at microscopic scales, whereas general relativity explains gravity as the curvature of spacetime caused by massive objects.

The two theories discuss forces existing on different scales. Bianconi employed an interesting approach to deal with this challenge. She proposes an entropic action where, instead of being a fixed background, spacetime works like a quantum operator  acting on quantum states and deciding how they change over time.

Next, she introduced a mathematical tool called G-field into the entropic action. This tool ensured that when spacetime interacts with matter as the quantum operator, the equations remain valid and don’t break any fundamental rules.

“By introducing the G-field, we obtain the modified Einstein equations and the equations of motion for the matter and the G-field,” Bianconi notes. The equations revealed how matter influenced the geometry of spacetime.

Moreover, at low energies, their modified equations behaved just like Einstein’s general relativity, suggesting that gravity may be an effect of the entropy. “This work proposes that quantum gravity has an entropic origin and suggests that the G-field might be a candidate for dark matter,” Bianconi added.

The equations go beyond general relativity

In addition to explaining the link between gravity and entropy and connecting quantum mechanics with general relativity, the equations in the study also left the researchers with a constant value that can explain why the universe is expanding at an accelerating rate.

“The theory goes further, predicting the emergence of a small, positive cosmological constant – a value that aligns with experimental observations of the universe’s accelerated expansion much better than for other pre-existing theories,” Bianconi notes.

These interesting findings could completely change our understanding of gravity, dark matter, and the universe. However, further research is needed to gather more evidence supporting these results.

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Green comet to pass Earth, won't be back for another 50,000 years

   visit:  https://hep-conferences.sciencefather.com/ After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1.   A newly discovered comet could be visible to the naked eye as it shoots past Earth and the Sun in the coming weeks for the first time in 50,000 years, astronomers have said. The comet is called C/2022 E3 (ZTF) after the Zwicky Transient Facility, which first spotted it passing Jupiter in March last year. After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1. It will be easy to spot with a good pair of binoculars and likely even with the naked eye, provided the sky is not too illuminated by city lights or the Moon. The comet "will be brightest when it is closest to the Earth", Thomas Prince, a physics professor at the California Institute of Technology who works at the Zwicky Transi...

"Explore the Fourth Dimension"

Fourth Dimension   The fourth dimension is a fascinating concept that has captured the imaginations of scientists, mathematicians, and artists for centuries. Unlike our three-dimensional world, which is limited by the linear flow of time, the fourth dimension is a realm of space and time that exists beyond our everyday experience. One way to visualize the fourth dimension is through the use of a hypercube, also known as a tesseract. A hypercube is a cube within a cube, with additional lines and edges connecting the vertices of the two cubes. It's impossible to construct in our three-dimensional world, but it provides a glimpse into what the fourth dimension might look like. Another way to understand the fourth dimension is through the concept of a wormhole, a theoretical passage through space-time that connects two distant points in the universe. A wormhole is like a shortcut through the fabric of space-time, allowing us to travel vast distances in an instant. While there is no de...
