Dark matter may have formed giant black holes: Here's how

Research suggests that early cosmos had different method for creating massive black holes




Researchers have proposed in a new paper that dark matter may have contributed to the formation of giant black holes in the early universe.

Truly gigantic black holes that appeared in the relatively young universe, are being revealed by more observations, especially with the James Webb Space Telescope, reported Space.com.

It would appear just a few hundred million years after the Big Bang that our cosmos was already home to black holes billions of times more massive than the sun.

Moreover, the only known way to create black holes is through the deaths of massive stars, but that process yields black holes with a few dozen solar masses.

There was just not enough time for the first stars to form, die, and then for those little black holes to eat enough matter to become supermassive, which is the reason why the huge black holes appeared so early.

Therefore, it's possible that the early cosmos had a different method for creating massive black holes, which would have started the process. The simplest method to accomplish that is to have massive clouds of helium and hydrogen collapse on themselves, bypassing star formation entirely and proceeding directly to the development of black holes.

However, molecular hydrogen, which is highly effective at cooling the gas, is often formed when gas clouds collapse. This prevents the cloud from collapsing directly into a black hole by causing it to break up into numerous smaller pieces, creating a cluster of young stars. High-energy ultraviolet (UV) light, which was scarce in the early universe due to the lack of stars, can be used to blast molecular hydrogen to prevent its creation.

Additionally, dark matter is an unconventional answer put out by Hao Jiao of McGill University in Quebec and associates in a new work published in March and posted to the preprint database arXiv.

It has been predicted by some models of dark matter that it's extremely light, even billions of times lighter than the neutrino, the lightest known particle. If dark matter is superlight, then at galactic scales, it acts more like a quantum ocean than a beehive of discrete particles.

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...
