A spinning universe could crack the mysteries of dark energy and our place in the multiverse

"It would be amazing if a simple rotation of the universe was the origin of dark energy."



The universe seems to be rotating, and if that is the case, then this could have major ramifications for some of the biggest questions in science, including those above. That's according to Polish theoretical physicist Nikodem Poplawski of the University of New Haven, who is well-known for his theory that black holes act as doorways to other universes.

"Dark energy is one of the most intriguing mysteries of the universe. Many researchers have tried to explain it by modifying equations of general relativity or suggesting the existence of new fields that could accelerate the universe's expansion," Poplawski told Space.com. "It would be amazing if a simple rotation of the universe was the origin of dark energy, especially that it predicts its weakening."

Evidence that the universe is rotating was recently delivered by the James Webb Space Telescope (JWST), which found that two-thirds of galaxies are rotating in the same direction. This suggests a lack of randomness and a preferred direction for cosmic rotation.

Additionally, Poplawski pointed out that other astronomical data seem to show that the angle between the most likely axis of the spinning galaxies and the axis of the bulk flow of nearby galaxy clusters is 98 degrees, meaning they are nearly perpendicular in relation to each other. That is something that is in accordance with the hypothesis that the universe is rotating.

A spinning universe isn't the only universe

To understand why a rotating universe implies more than one universe, Poplawski refers to "frames of reference." These are sets of coordinate systems that are integral to physics, which allow motion and rest to be measured.

Imagine two scientists, Terra and Stella. Each is in their own frame of reference, but Terra on Earth, Stella in a spacecraft traveling past our planet. Terra sees Stella's frame of reference (the spacecraft) moving in relation to her own (the Earth), which is at rest. Stella, meanwhile, sees her frame of reference at rest while it is Terra's frame of reference in motion as the Earth races away.

Poplawski pointed out that if the universe is rotating, then its frame of reference is rotating, and that only makes sense if it is rotating in relation to at least one other frame of reference.

"If the universe is rotating, it must rotate relative to some frame of reference corresponding to something bigger," he continued. "Therefore, the universe is not the only one; it is a part of a multiverse."

For Poplawski, the simplest and most natural explanation of the origin of the rotation of the universe is black hole cosmology.

Black hole cosmology suggests that every black hole creates a new baby universe on the other side of its event horizon, the one-way light-trapping surface that defines the outer boundary of a black hole.

The theory replaces the central singularity at the heart of a black hole with "spacetime torsion" that gives rise to repulsive gravity that kick-starts the expansion of a new universe.

"Because all black holes form from rotating objects, such as rotating stars or in the centers of rotating galaxies, they rotate too," Poplawski said. "The universe born in a rotating black hole inherits the axis of rotation of the black hole as its preferred axis."

In other words, our universe may be spinning in a preferred direction because that is the way that the black hole it is sealed within is spinning.

"A black hole becomes an Einstein-Rosen bridge or a 'wormhole' from the parent universe to the baby universe," Poplawski explained. "Observers in the new universe would see the other side of the parent black hole as a primordial white hole."

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...

Scientists Discover New “Hall Effect” That Could Revolutionize Electronics

Scientists discovered a new Hall effect driven by spin currents in noncollinear antiferromagnets, offering a path to more efficient and resilient spintronic devices . A research team led by Colorado State University graduate student Luke Wernert and Associate Professor Hua Chen has identified a previously unknown type of Hall effect that could lead to more energy-efficient electronic devices . Their study, published in Physical Review Letters, was conducted in collaboration with graduate student Bastián Pradenas and Professor Oleg Tchernyshyov of Johns Hopkins University. The researchers uncovered evidence of a new property, dubbed the “Hall mass,” in a class of complex magnetic materials known as noncollinear antiferromagnets . The traditional Hall effect, discovered by Edwin Hall at Johns Hopkins in 1879, describes how an electric current is deflected sideways when subjected to an external magnetic field, generating a measurable voltage. This effect plays a crucial role in technologi...
