Who owns the universe?
With many countries, companies and individuals intensifying their space exploration programs, questions about rights, ownership and the feasibility of manned space missions are coming to the fore of public debate......»»
A new possible explanation for the Hubble tension
The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values......»»
The Universe in a lab: Testing alternate cosmology using a cloud of atoms
We can't experiment with the Universe, but we can make something that works like it. Enlarge / Density waves in a Bose-Einstein condensate. (credit: NASA) In the basement of Kirchhoff-Institut für Physik in Germany, res.....»»
Prototype for DUNE detector will test new technology that can handle more neutrinos
Long before the Deep Underground Neutrino Experiment takes its first measurements in an effort to expand our understanding of the universe, a prototype for one of the experiment's detectors is blazing new trails in neutrino detection technology......»»
Why don"t we see robotic civilizations rapidly expanding across the universe?
In 1950, while sitting down to lunch with colleagues at the Los Alamos Laboratory, famed physicist and nuclear scientist Enrico Fermi asked his famous question: "Where is everybody?" In short, Fermi was addressing the all-important question that has.....»»
New astrophysics model sheds light on additional source of long gamma-ray bursts
Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows—gamma-ray bursts, or GRBs. The new unified model confi.....»»
For its next trick, Gaia could help detect background gravitational waves in the universe
Ripples in a pond can be captivating on a nice sunny day as can ripples in the very fabric of space, although the latter are a little harder to observe. Using the highly tuned Gaia probe, a team of astronomers proposes in a paper posted to arXiv prep.....»»
If warp drives are impossible, maybe faster-than-light communication is still on the table?
I'm sure many readers of Universe Today are, like me, fans of the science fiction genre. From the light sabers of "Star Wars" to the neuralyzer of "Men in Black," science fiction has crazy inventions aplenty and once science fiction writers dream it,.....»»
Researchers pioneer a new way of searching for dark matter
The existence of dark matter is a long-standing puzzle in our universe. Dark matter makes up about a quarter of our universe, yet it does not interact significantly with ordinary matter......»»
New constraints on the presence of ultralight dark matter in the Milky Way
Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional experimental meth.....»»
A galaxy only 350 million years old has surprising amounts of metal
Astrophysicists working with the JWST have found a surprising amount of metal in a galaxy only 350 million years after the Big Bang. How does that fit in with our understanding of the universe?.....»»
Does Monarch: Legacy of Monsters signal the slow death of the cinematic universe as we know it?
Monarch: Legacy of Monsters is a frequently entertaining adventure series, but it also feels like a relic of an era that's either dead or dying......»»
"Triple star" discovery could revolutionize understanding of stellar evolution
A ground-breaking new discovery by University of Leeds scientists could transform the way astronomers understand some of the biggest and most common stars in the universe. The paper, "Gaia uncovers difference in B and Be star binarity at small scales.....»»
The universe can"t hide behind the Zone of Avoidance any longer
Our view of the cosmos is always limited by the fact we are located within a galaxy filled with interstellar gas and dust. This is most dramatically seen in the central region of the Milky Way, which is filled with so much dust that it is sometimes r.....»»
Physicists answer question of Supergalactic Plane"s absent spiral galaxies
Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our local universe called the Supergalactic Plane......»»
Can Apple Vision Pro reinvent the computer, again?
As the universe counts down the clock to Apple's upcoming "reinvention" of augmented reality computing with its new Vision Pro early in the new year, it's useful to take a look at how successful it has been at reinventing the computing platform in th.....»»
Scientists disagree on how fast the universe is expanding, and new tech is making it worse
Usually new tech brings us closer to understanding more of the universe, but in the field of cosmology, one uncertainty is only getting worse......»»
The echoes from inflation could still be shaking the cosmos today
In the very early universe, physics were weird. A process known as inflation, during which the universe went from a single infinitesimal point to everything we see today, was one such instance of those weird physics. Now, scientists from the Chinese.....»»
The universe is expanding faster than theory predicts—physicists are trying to explain the mismatch
Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth......»»
Who owns and controls Danish agricultural land?
Investments are not just about money, and they don't just impact the agricultural economy but also the dynamics of the agricultural sector itself. In Denmark, external investments have played an increasingly influential role in shaping the sector. Ri.....»»
How to think about a four-dimensional universe
In Einstein's famous theory of relativity the concepts of immutable space and time aren't just put aside, they're explicitly and emphatically rejected. Space and time are now woven into a coexisting fabric. That is to say, we truly live in a four-dim.....»»
