    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...

    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...

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...

    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...
  • U.S. Navy controls inventions that claim to change "fabric of reality"

    The U.S. Navy controls patents for some futuristic and outlandish technologies, some of which, dubbed "the UFO patents," came to life recently. Of particular note are inventions by the somewhat mysterious Dr. Salvatore Cezar Pais, whose tech claims to be able to "engineer reality." His slate of highly-ambitious, borderline sci-fi designs meant for use by the U.S. government range from gravitational wave generators and compact fusion reactors to next-gen hybrid aerospace-underwater crafts with revolutionary propulsion systems, and beyond. Of course, the existence of patents does not mean these technologies have actually been created, but there is evidence that some demonstrations...
  • For The First Time, Astronomers May Have Heard The Background 'Hum' of The Universe

    01/11/2021 11:36:35 AM PST · by Red Badger · 42 replies ^ | MICHELLE STARR | 11 JANUARY 2021
    Based on what we know about gravitational waves, the Universe should be full of them. Every colliding pair of black holes or neutron stars, every core-collapse supernova - even the Big Bang itself - should have sent ripples ringing across spacetime. After all this time, these waves would be weak and hard to find, but they're all predicted to make up a resonant 'hum' that permeates our Universe, referred to as the gravitational wave background. And we may have just caught the first hint of it. You can think of the gravitational wave background as something like the ringing left...

    Explanation: Barred spiral galaxy NGC 1365 is truly a majestic island universe some 200,000 light-years across. Located a mere 60 million light-years away toward the chemical constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax Cluster of galaxies. This impressively sharp color image shows the intense, reddish star forming regions near the ends of central bar and along the spiral arms, with details of the obscuring dust lanes cutting across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing...

More precisely, if the entire sky were smeared out, what color would the final mix be? This whimsical question came up when trying to determine what stars are commonplace in nearby galaxies. The answer, depicted above, is a conditionally perceived shade of beige. In computer parlance: #FFF8E7. To determine this,...

    Full Title: We're as good as it gets: Intelligent life is extremely UNLIKELY to exist anywhere else in the universe because it took a series of miracles for humans to evolve, say scientists Statisticians say the evolution of intelligent life is 'exceptionally rare', and that human-like civilisations are extremely unlikely to exist on other planets. In a new paper, Oxford researchers theorise that, for life to evolve in the same way elsewhere in the universe, it would take longer than the whole of Earth's projected lifespan. Evolution on Earth from the Big Bang up until the current day has involved...

    Prof Claudia de Rham’s ‘massive gravity’ theory could explain why universe expansion is accelerating Cosmologists don’t enter their profession to tackle the easy questions, but there is one paradox that has reached staggering proportions. Since the big bang, the universe has been expanding, but the known laws of physics suggest that the inward tug of gravity should be slowing down this expansion. In reality, though, the universe is ballooning at an accelerating rate. Scientists have come up with a name – dark energy – for the mysterious agent that is allowing the cosmos to expand so rapidly and which is...
