Scientists believe galaxies like UGC 477 are largely dominated by dark matter.
A new study suggests that the collapse of a massive star could spark the creation of a tiny expanding universe rather than a black hole. The resulting object, called a gravastar, w...
Modern cosmology rests on a simple assumption: if we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known...
Tiny galaxies orbiting the Milky Way may hold clues to one of cosmology’s biggest mysteries. Ultra-faint dwarf galaxies are among the smallest known galaxies orbiting the Milky Way...
Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden f...
It's like a baby Big Bang. The post Scientists Propose That Entire Universes Can Form Inside Collapsing Stars appeared first on Futurism.
The mysterious substance that binds galaxies together could naturally be 'in tune' with a hidden fifth dimension, according to a new theory aiming to shed light on one of science's...
The universe may have its own version of Heisenberg's uncertainty principle, and that might be enough to explain dark energy without invoking any new physics at all.
A mysterious neutrino signal has led astronomers to a surprising discovery: a hidden star-forming galaxy, not a supermassive black hole, may be generating some of the Universe’s mo...
Like the spin of a cosmic coin, a unique set of particle oscillations could ultimately decide the fate of the Universe’s biggest suns.Continue ReadingCategory: Physics,
Imagine standing in the emptiest place the universe has to offer, a stretch of cosmic ocean so vast that light takes tens of millions of years to cross it, and yet still finding co...
New study confirms accelerating expansion of the universe The post Cosmic crisis averted as supernovae put dark energy back on track appeared first on Physics World.
About 25 years ago, astrophysicists noticed that the universe’s expansion is accelerating. To account for this observation, physicists came up with a new type of energy – called da...
Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like the Milky Way, no planets, and no heavy elements such as...
Mysterious "little red dots" discovered in the early universe by the James Webb Space Telescope could harbor buried black holes that fire high-energy neutrinos through the cosmos.
Once dismissed as empty expanses between galaxies, cosmic voids are becoming one of the most promising tools for probing the universe’s biggest mysteries.
Astronomers have identified a possible new example of one of the universe's strangest galaxy types: galaxies that appear to contain little or no dark matter. The newly studied pair...
DAL BIG BANG AL DESTINO FINALE DELL'UNIVERSO: LE DOMANDE FONDAMENTALI DELLA FISICA E DELLA COSMOLOGIAContinue reading on Medium »
We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank...
Neutrinos are one of the fundamental particles of the universe. They live a ghostly existence with no electric charge, very little mass and extremely few interactions with matter....
A star-forming galaxy in the early universe might have sent a ghostly particle known as a neutrino crashing into the ice at Earth’s South Pole, after an 11 billion-year journey thr...
A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have follo...
A technique called echo mapping suggests supermassive black holes, like that at the heart of the Milky Way, are surrounded by clusters of dark matter.
Inside some very special black holes, there may be a boundary called a Cauchy horizon. Columnist Leah Crane explores the place beyond which physics breaks and anything is possible
