The fabric of the cosmos, as we currently understand it, comprises three primary components: 'normal matter,' 'dark energy,' and 'dark matter.' However, new research is turning this established model on its head. A recent study conducted by the University of Ottawa presents compelling evidence that challenges the traditional model of the universe, suggesting that there may not be a place for dark matter within it. Dark matter, a term used in cosmology, refers to the elusive substance that does not interact with light or electromagnetic fields and is only identifiable through its gravitational effects. Despite its mysterious nature, dark matter...

The universe is expanding faster and faster, but not all scientists agree that dark energy is the cause. Perhaps, instead, our universe keeps colliding with and absorbing smaller 'baby universes,' a new theoretical study suggests. Our universe is expanding at an ever-accelerating rate — a phenomenon that all theories of cosmology agree upon but none can fully explain. Now, a new theoretical study offers an intriguing solution: Perhaps our universe is expanding because it keeps colliding with and absorbing "baby" parallel universes. Studies of the cosmic microwave background, the afterglow of the Big Bang, have revealed that our universe is...

The Orion: A molecular cloud shows cosmic filamentary structures where stars are being born. Image: ESA / Herschel / Ph. André, D Polychroni, A. Roy, V Könyves, N Schneider for the Gould Belt survey Key Program ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In the first part of this series, we saw that electromagnetic processes in plasmas – electrically conducting gases – could, over trillions of years, produce the giant filaments that we see today as the largest structures in the universe. This happened without a Big Bang, without dark energy or dark matter, based on processes that we observe here on Earth in the laboratory...

Christmas is less than a week away, and even the night sky is spreading some holiday cheer with what could be the largest Christmas tree in the universe. On Tuesday, NASA released an image of NGC 2264, also known as the "Christmas Tree Cluster," a group of young stars located around 2,500 light-years away from Earth. The image was captured by the Chandra X-ray Observatory, and the green nebula surrounding the stars resembled a festive Christmas tree. Some stars in the cosmic Christmas tree are only one-tenth the size of our sun, while others are several times larger. NASA added...

Although we still don't know the question, we know that the answer to life, the Universe, and everything is 42. Here are 5 possibilities. The answer to the ultimate question about life, the Universe, and everything has been asserted to be 42 by the infamous Douglas Adams. But... if 42 is the answer, what's the question? Credit: Ben Gibson/Big ThinkKey Takeaways If you programmed the ultimate supercomputer to give the answer to the ultimate question in the Universe, legend has it that, after 7.5 million years, the answer would at last be revealed: 42. Only, what's the point of knowing...

Utah's Noelia Voigt has been crowned Miss USA in a glitzy ceremony that saw the contestants showcase their fashion prowess in shimmering mini dresses and stunning gowns. The 72nd pageant also featured the first married state titleholder following a rule by Miss Universe that has allowed married women and mothers to compete for the first time in its seven-decade history. Noelia Voigt, 23, oozed glamour last night in a silver frock with a thigh-high split, before swapping into an eye-catching gem-covered gold gown ahead of being crowned Miss USA. Savannah Gankiewicz of Hawaii placed as first-runner up at the Grand...

Dismantling the belief in a static universe, Edwin Hubble's revolutionary observations in the 1920s laid the groundwork for our understanding of a continually expanding cosmos. However, we must seek to reconcile this theory with observations that are consistent with a non-expanding universe, writes Tim Anderson. You have been taught that the universe began with a Big Bang, a hot, dense period about 13.8 billion years ago. And the reason we believe this to be true is because the universe is expanding and, therefore, was smaller in the past. The Cosmic Microwave Background is the smoking gun for the Big Bang,...

A biologically male transgender model was crowned as ‘Miss Netherlands’ and will compete for the title of Miss Universe later this year in El Salvador. Rikkie Kolle, a 22-year-old model, has been selected as Miss Netherlands 2023, the first biological male to win the historically female competition.

Hubble Ultra Deep Field It’s possible that the universe isn’t uniform past what we can see, and conditions are wildly different from place to place, says Caltech astrophysicist Sean Carroll. “That possibility is the cosmological multiverse. We don’t know if there is a multiverse in this sense, but since we can’t actually see one way or another, it’s wise to keep an open mind.” “Astronomers estimate that the observable universe — a bubble 14 billion light-years in radius, which represents how far we have been able to see since its beginning — contains at least two trillion galaxies and...

Physicists are building neural networks out of vibrations, voltages and lasers, arguing that the future of computing lies in exploiting the universe’s complex physical behaviors.Inside a soundproofed crate sits one of the world’s worst neural networks. After being presented with an image of the number 6, it pauses for a moment before identifying the digit: zero. Peter McMahon, the physicist-engineer at Cornell University who led the development of the network, defends it with a sheepish smile, pointing out that the handwritten number looks sloppy. Logan Wright, a postdoc visiting McMahon’s lab from NTT Research, assures me that the device...

The validity of this theory is based on three main facts: a) the redshift of spectral lines of distant stars; b) the presence of cosmic microwave background radiation; c) the theory of primary Big Bang nucleosynthesis (BBN) of light H2 , He3 , He4 , Li6 and...

Artist’s impression of cosmic filaments: huge bridges of galaxies and dark matter connect clusters of galaxies to each other. Galaxies are funneled on corkscrew like orbits towards and into large clusters that sit at their ends. Their light appears blue-shifted when they move towards us, and red-shifted when they move away. Credit: AIP/ A. Khalatyan/ J. Fohlmeister ==================================================================================== By mapping the motion of galaxies in huge filaments that connect the cosmic web, astronomers at the Leibniz Institute for Astrophysics Potsdam (AIP), in collaboration with scientists in China and Estonia, have found that these long tendrils of galaxies spin on the...

Experimental setup. As a beam of beryllium comes in from the left, the deuteron Trojan horse intercepts it at the target and delivers its neutron soldier. This allows the decay products of the beryllium and neutron reactions to be captured by a curved array of six detectors on the right. Credit: Hayakawa et al. There is a significant discrepancy between theoretical and observed amounts of lithium in our universe. This is known as the cosmological lithium problem, and it has plagued cosmologists for decades. Now, researchers have reduced this discrepancy by around 10%, thanks to a new experiment on...

Galaxies reside in filaments hundreds of millions of light-years long, on a backbone of dark matter. And, where those filaments meet, there are galaxy clusters. Between them are massive voids, where galaxies are sparse. Now a team of astronomers in Germany and their colleagues in China and Estonia have made an intriguing discovery.These massive filaments are rotating, and this kind of rotation on such a...

Then there are all the suggestions that the UFOs are optical illusions, meteorological phenomena or electromagnetic events The Silly Season has come early this year. Normally it happens in August, when wicked people all over the northern hemisphere temporarily stop doing evil things to take their children to the beach and enjoy the last of the summer. With no bad news to report, desperate journalists will run any story, however silly. Why is it Silly Season in June this year? Because the US Department of Defence has announced that it will release a report on 'Unidentified Aerial Phenomena' (UAPs), which...

A peculiar ranch incident in New Mexico nearly 75 years ago has kept UFO enthusiasts intrigued at the possible presence of alien life on Earth until this very day.ROSWELL, N.M. — A peculiar ranch incident near Roswell, New Mexico nearly 75 years ago still intrigues UFO enthusiasts about the possible presence of extra-terrestrial life on Earth. Amid a violent summer thunderstorm in July 1947, a large flying object fell out of favor with the gods and crashed on a ranch about 75 miles northwest of the military town. The events to follow gave rise to Roswell as a tourist attraction...

Prior to his death on March 14, 2018, the English theoretical physicist created a theory that changed the way we think about the universe. Working with Belgian professor, Thomas Hertog, from the Katholieke Universiteit Leuven (KU Leuven), Hawking theorised that our three-dimensional reality is an illusion. Put simply, Professors Hawking and Hertog speculated that all information in the universe is stored on a flat 2D surface and our so-called “solid” world around us is then projected from that information. Back in 2018, Professor Hertog said: “It's a very precise mathematical notion of holography that has come out of string theory...
