Astronomers Discover A Water Reservoir Floating In Space That Is Equivalent To 140 Trillion Times All The Water In The Earth’s Ocean

Posted by in category: cosmology

There is a reserve of water the size of 140 trillion oceans lurking in a faraway supermassive black hole, the universe’s largest deposit of water and 4,000 times the amount found in the Milky Way.

This amount of water was discovered by two teams of astronomers 12 billion light-years away, where it appears as vapor dispersed across hundreds of light-years.

The reservoir was discovered in a quasar’s gaseous area, which is a brilliant compact region in the heart of a galaxy powered by a black hole. This finding demonstrates that water may be present throughout the cosmos, even at the start.

Ionization of Gravitational Atoms

Posted by in categories: cosmology, particle physics

By: William Brown, Biophysicist at the Resonance Science Foundation

Stellar mass black holes, like elementary particles, are remarkably simple objects. They have three primary observable properties: mass, spin, and electric charge. The similarities with elementary particles, like the proton, doesn’t stop there, as stellar mass black holes in binary systems can also form bound and unbound states due to interaction of orbital clouds (from boson condensates), uncannily analogous to the behavior and properties of atoms.

MIT Physicists Harness Quantum “Time Reversal” for Detecting Gravitational Waves and Dark Matter

Posted by in categories: cosmology, particle physics, quantum physics

A new technique to measure vibrating atoms could improve the precision of atomic clocks and of quantum sensors for detecting dark matter or gravitational waves.

Gravitational waves are distortions or ripples in the fabric of space and time. They were first detected in 2015 by the Advanced LIGO detectors and are produced by catastrophic events such as colliding black holes, supernovae, or merging neutron stars.

Deep Space ‘Ghost Particle’ Reveals Clue in Centuries-Old Cosmic Mystery

Scientists tracked a neutrino back to a violent black hole — and it could help explain where elusive cosmic rays originate.

Scientists revealed for the first time the origin of neutrinos

Posted by in categories: cosmology, particle physics

An international research team led by the University of Würzburg and the University of Geneva (UNIGE) is shedding light on one aspect of this mystery: neutrinos are thought to be born in blazars, galactic nuclei fed by supermassive black holes.

Sara Buson has always thought of it as a significant task. In 2017, the researcher and his associates introduced a blazar (TXS 0506+056) as a potential neutrino source for the first time. That study sparked a scientific debate about whether there truly is a connection between blazars and high-energy neutrinos.

After taking this initial, positive step, Prof. Buson’s team received funding from the European Research Council to launch an ambitious multi-messenger research project in June 2021. Analyzing numerous signals (or “messengers,” for example, neutrinos) from the Universe is required. The primary objective is to shed light on the origin of astrophysical neutrinos, potentially confirming blazars as the first highly certain source of high-energy extragalactic neutrinos.

Scientists Contemplate Alien Contact (The Daily Galaxy Archive)

Posted by in category: cosmology

“We know now that in the early years of the twentieth century this world was being watched closely by intelligence greater than man’s…across an immense ethereal gulf, minds that to our minds as ours are to the beasts in the jungle, intellects vast, cool and unsympathetic, regarded this earth with envious eyes and slowly and surely drew their plans against us.” So began actor Orson Welles’ chilling Mercury Theater radio performance on October 30, 1938 that Martians were invading, leading terrified listeners to believe that Earth was under attack by hostile aliens.

Welles’ chilling performance was a dramatization of the H.G. Wells science-fiction classic, “The War of the Worlds,” and was part of a weekly series of dramatic broadcasts created in collaboration with the Mercury Theatre on the Air for CBS, according to a transcript of the program.

Physicists harness quantum ‘time reversal’ to measure vibrating atoms

Posted by in categories: cosmology, particle physics, quantum physics

The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of atomic clocks as well as quantum sensors, which are systems of atoms whose fluctuations can indicate the presence of dark matter, a passing gravitational wave, or even new, unexpected phenomena.

A major hurdle in the path toward better quantum measurements is noise from the , which can easily overwhelm subtle atomic vibrations, making any changes to those vibrations devilishly hard to detect.

Now, MIT physicists have shown they can significantly amplify quantum changes in atomic vibrations, by putting the particles through two key processes: and time reversal.

Stephen Hawking’s Final Research Predicts The End Of The Universe And Existence Parallel Universes

Posted by in categories: cosmology, space travel

Two weeks before his death, famed scientist Stephen Hawking published a research article predicting parallel universes and along with the end of our own.

Hawking and co-author Thomas Hertog published their results in “A Smooth Exit from Eternal Inflation,” outlining how scientists may also be able to discover other universes using spaceships. According to Hertog, Hawking completed the work on his deathbed, leaving a legacy worthy of the Nobel Prize.

Mysterious radio “heartbeat” signal detected from distant galaxy

Posted by in categories: cosmology, mapping

Astronomers from MIT report today that they have discovered a mysterious signal with a pattern akin to a heartbeat, emanating from a far-off galaxy that is billions of light-years from Earth. Exactly what the source may be of this regular pulse of radio waves remains a mystery, as it is the first time that such a signal has been recorded.

They have identified the signal as a fast radio burst (FRB), which is typically an intensely strong burst of radio waves of unknown astrophysical origin that lasts only a few milliseconds at most. This new signal, labelled FRB 20191221A, is unusual, because it persists for up to three seconds, which is about 1,000 times longer than the average FRB. Within this time, there are shorter bursts of radio waves that repeat every 0.2 seconds in a clear periodic pattern, similar to that of a beating heart.

Since the first FRB was discovered in 2007, hundreds of similar radio flashes have been detected across the universe, most recently by the Canadian Hydrogen Intensity Mapping Experiment, or CHIME, an interferometric radio telescope that is located at the Dominion Radio Astrophysical Observatory in British Columbia, Canada. CHIME is designed to pick up radio waves emitted by hydrogen in the very earliest stages of the universe, but the telescope is also sensitive to fast radio bursts. Since it began observing the sky in 2018, CHIME has detected hundreds of FRBs emanating from different parts of the sky.
