What is the universe expanding into if it's already infinite?
Hamden CT (SPX) Dec 10, 2024 When you bake a loaf of bread or a batch of muffins, you put the dough into a pan. As the dough bakes in the oven, it expands into the baking pan. Any chocolate chips or blueberries in the muffin batter become farther away from each other as the muffin batter expands. The expansion of the universe is, in some ways, similar. But this analogy gets one thing wrong - while the dough expands into the baking pan, the universe doesn't have anything to expand into. It just expands into itself. It ca ... read more |

Falsifying the role of the Anthropic Principle in CosmologyParis, France (SPX) Dec 10, 2024 The Anthropic Principle (AP), first proposed by Brandon Carter in 1973, suggests that the universe is uniquely fine-tuned to support life. This idea has long sparked philosophical and scientific deb ... more 
Webb telescope's largest study of universe expansion confirms challenge to cosmic theoryBaltimore MD (SPX) Dec 10, 2024 New observations from the James Webb Space Telescope suggest that a new feature in the universe-not a flaw in telescope measurements-may be behind the decadelong mystery of why the universe is expan ... more 
Astronomers uncover key clues to the formation of giant galaxiesLondon, UK (SPX) Dec 05, 2024 Astronomers are making significant progress in solving the mystery of how the universe's largest galaxies were formed, a puzzle that has intrigued scientists for decades. A recent study by res ... more 
Particle research gets closer to answering why we're hereCincinnati OH (SPX) Dec 06, 2024 Physicists hope to answer fundamental questions about the origins of the universe by learning more about its tiniest particles. University of Cincinnati Professor Alexandre Sousa helped outlin ... more |

Searching for evidence of primordial black holes in planets and everyday materialsLos Angeles CA (SPX) Dec 03, 2024 The formation of black holes is often associated with massive stars collapsing under their own gravity. However, new research suggests the chaotic conditions of the early universe may have enabled t ... more 
'Spooky action' at a very short distance: Scientists map out quantum entanglement in protonsUpton NY (SPX) Dec 03, 2024 Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators have a new way to use data from high-energy particle smashups to peer inside protons. Their appro ... more 
Novel supernova observations grant astronomers a peek into the cosmic pastColumbus OH (SPX) Nov 26, 2024 An international team of researchers has made new observations of an unusual supernova, finding the most metal-poor stellar explosion ever observed. This rare supernova, called 2023ufx, origin ... more 
New bar set for simulating the universe in the Exascale eraOak Ridge TN (SPX) Nov 26, 2024 The universe just got a whole lot bigger - or at least in the world of computer simulations, that is. In early November, researchers at the Department of Energy's Argonne National Laboratory u ... more |

Attosecond X-ray pulses at high repetition rates revolutionize atomic imaging
Berlin, Germany (SPX) Nov 26, 2024 A collaborative team of scientists from European XFEL and DESY has achieved a significant milestone in X-ray science by producing high-power attosecond hard X-ray pulses at unprecedented megahertz repetition rates. This technological leap promises transformative applications in ultrafast electron dynamics research and damage-free atomic-level imaging. The researchers successfully created single-spike hard X-ray pulses with energies exceeding 100 microjoules and pulse durations of only a few hundre ... read more
