lol. I always laugh at the gross ignorance of these guys. My background is in engineering and I read a lot, I just decided that it is pointless discussing intellectually with nairalanders as most are just carried away with believes not science. Most pretend to know science and think using scientific words makes them knowledgeable. So many of them here. No point explaining shit to them, they are believers in different forms not science oriented. Science is not belief based, it I'd evidence based. It is not based on stories, it is based on history. Examinable sources not obscure mythism

Many physicists around the world that support these ideas as shown above are ignorant but you, who don't have any degree in Physics, are knowledgeable about Physics. Lols.

Some jokes tell themselves

LordReed:
You wrote "higher beings", who are these higher beings?

I think my posts on this subject are clear enough, and if you read them, you wouldn't need to ask this question.

KnownUnknown:
Lol. People do like to be deceived.

I had to go check the dictionary for the meaning of insightful because I don’t understand how that new age bullshit was insightful. “Frequencies, energies, waves, photon souls” . If A001 is a “physicist”, I am a Nobel prize winner in astrophysics.

Everyone should at least watch the summary of energy from the 2:50 mark from someone who knows what he’s talking about. Also watch from the 23:50 mark.

Stop yarning dust. The team lacked urgency and the tactics was wrong , stop blaming Buhari

Lols. You're taking that comment of mine too seriously. It's just a joke, Mr Buharist

LordReed:
Someone said "It's typical of a white European to come to Africa, see the wondrous pyramids and claim that some otherworldly being did it or gave them the knowledge because he thinks Africans cannot do such a thing."

You should consider this, you might be buying into a racist agenda.

You obviously don't know the history of the ancient Egyptians.

If you do, you'd reaiize they attributed all their achievements to their pagan gods and goddesses, chief among which are Atum or Tem, Ra, and Amun.

Hence, you'd see the names of their gods at the root of their own names. Do you think it's a coincidence names like Aten (the other name of Atum), Ra, Amun are parts of the names of many of their pharaohs?

The paintings of their pagan gods (the source of their knowledge ad civilization) are on many pyramids in Egypt.

Or you think their gods who are their ancestors are fictional entities? Lols.

What The Many-Worlds Interpretation of Quantum Physics Really Means
https://www.forbes.com/sites/chadorzel/2016/01/05/what-the-many-worlds-interpretation-of-quantum-physics-really-means/?sh=61a749f21102

At the core, a person is a ray of light or photon, which doesn't experience time because it's massless, and all things happen at once.

In other words, the core of a person (that photon) exists in all places, all worlds, all realms, all universes at once.

But the brain of the body filters most information about this away, leaving us with a minute part, just a speck.

At death, it's that core, the ray of light, that leaves its shell (body) during the death of the body as portrayed in some Hollywood movies.

(That's why the ancient Egyptians and some philosophers say the soul is imprisoned in the body on Earth.)

Death is only a transition of consciousness, not the end of one's existence, and when a person dies here on Earth, they become awake in another world.

A person doesn't really die but they (their consciousness) transition into another realm (determined naturally by their brain thoughts on Earth) because the core of a person (that photon) doesn't experience time, and its existence has no end nor beginning.

But the average human, whose brain filters most things happening in his world just like his sense organs do, sees things sequentially or chronologically.

But his core doesn't.

(If you only knew the sheer amount of information about our surroundings and our world that the brain filters away from our consciousness.)

We're only aware of a small percentage of all things happening in the environment due to the limitations of our sense organs and the brain.

At this point in time, the many-worlds interpretation of quantum mechanics isn't a well established concept in Physics, but it won't be so for long and will soon be developed further by scientists.

And in the future, scientists will build a device (a sort of a microscope) that looks into other realms of existence just like microscopes allow us to see into the microbial world or realm.

If you can't observe or measure something, it doesn't mean that thing doesn't exist.

When the Super Eagles had a meeting with Buhari earlier today, I knew their defeat, the first and last in the tournament, was around the corner

The spirit of Buhari (failure) has jinxed the team that put up a stellar performance in the group stage.

I hope the players have learned their lesson not to associate with failure before a crucial game.

Like Anthony Joshua, like Super Eagles.

BegAt40:
it's hard for me to believe that there's any supernatural beign communicating with any natural beign tho. I'll like to know if there's any other mean they might have achieved this without anything God, God or supernatural in the explanation.

I've not mentioned anything like supernatural beings. But there are higher beings or early beings which limited beings (the average humans) regard as gods and goddesses and worship ignorantly as God.

It's these higher/past beings that rule the world today through the religions they founded, which are their personal philosophies.

But supernatural things or beings don't exist in our world or physical realm. Humans do all things on Earth, physically (naturally) and psychologically, i.e. psychophysically.

Apart from the physical realm, there are many other realms in existence, with each existing independently of the other.

If you've had lucid dreams or near-death experience, you'd have seen other realms in existence.

Some higher beings commune with some humans they chose in non-physical realms via lucid dreams and meditations and reveal things to them.

The mechanism of communication works scientifically, and there's nothing supernatural about it.

It all has to do with waves, frequency, and energy.

The core of each person is a ray of light or photon, which is the soul, and it exists in all realms or worlds or universes at once because time doesn't really exist but is a mental construct.

It's the function of the heart to tune a person's heartbeat for their core (consciousness or soul) to match the frequency of any particular realm so they can interact with other beings in the realm and remember the things they did in other realms.

The way a higher being communes with a human via lucid dreams or meditation via a shared frequency is similar in some way to when two atheists on the same or similar thinking frequency agrees with each other about many issues concerning religion.

So, it's said both of them are on the same page or wavelength. But the religious person won't understand them because he's on a lower thinking frequency.

On this planet, the average heartbeat of humans is similar, and hence we're hosted on a specific bandwidth of frequencies in a specific region of the universe.

This is the frequency (or a close value to it particular to that person) any higher being that wants to communicate with a human on Earth tunes to via meditation to interact with the person.

You don't have to believe these things (and I don't expect you to). But you should know life or reality is a lot deeper than we think, and there are some names that can never be forgotten on Earth.

(A number of such are names of higher beings religious people call God.)

Reality exists in different bases and frequencies and is fundamentally mathematical.

BegAt40:
But how did ancient pagans come about these facts?

I

Use of the brain, fasting, meditation, sometimes pure luck.

Also, their gods and goddesses (which are deified humans or higher beings) revealed some hidden knowledge about reality to them, especially those ancient Egyptians.

That gave them some edge above their peers.

BegAt40:
@hardmirror
I'll be glad if you can provide explanation to this sir.
https://zamzam.com/blog/scientific-facts-in-quran/

The ancient humans, especially the homo erectuses and the ancient Egyptians, were not primitive people as most of us believe today.

A number of scientific concepts, principles, and facts in modern physics had been developed and formulated in Ancient Egypt, and the founders of Christianity and Islam simply plagiarized the religious texts of those ancient Egyptians.

That's why you would come across some scientific facts in the Bible and Qur'an.

There's no single aspect of those Abrahamic religions that is original.

Worldwide coordinated search for dark matter

An international team of researchers with key participation from the PRISMA+Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) has published for the first time comprehensive data on the search for dark matter using a worldwide network of optical magnetometers.

According to the scientists, dark matter fields should produce a characteristic signal pattern that can be detected by correlated measurements at multiple stations of the GNOME network. Analysis of data from a one-month continuous GNOME operation has not yet yielded a corresponding indication.

However, the measurement allows the formulation of constraints on the characteristics of dark matter, as the researchers report in the journal Nature Physics.



GNOME stands for Global Network of Optical Magnetometers for Exotic Physics Searches. Behind it are magnetometers distributed around the world in Germany, Serbia, Poland, Israel, South Korea, China, Australia, and the United States.

With GNOME, the researchers particularly want to advance the search for dark matter—one of the most exciting challenges of fundamental physics in the 21st century. After all, it has long been known that many puzzling astronomical observations, such as the rotation speed of stars in galaxies or the spectrum of the cosmic background radiation, can best be explained by dark matter.

"Extremely light bosonic particles are considered one of the most promising candidates for dark matter today.

"These include so-called axion-like particles—ALPs for short," said ProfessorDr. Dmitry Budker, professor at PRISMA+and at HIM, an institutional collaboration of Johannes Gutenberg University Mainz and the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.

"They can also be considered as a classical field oscillating with a certain frequency. A peculiarity of such bosonic fields is that—according to a possible theoretical scenario—they can form patterns and structures.

"As a result, the density of dark matter could be concentrated in many different regions—discrete domain walls smaller than a galaxy but much larger than Earth could form, for example."

"If such a wall encounters the Earth, it is gradually detected by the GNOME network and can cause transient characteristic signal patterns in the magnetometers," explained Dr. Arne Wickenbrock, one of the study's co-authors.

"Even more, the signals are correlated with each other in certain ways—depending on how fast the wall is moving and when it reaches each location."

The network meanwhile consists of 14 magnetometers distributed over eight countries worldwide.

Nine of them provided data for the current analysis.

The measurement principle is based on an interaction of dark matter with the nuclear spins of the atoms in the magnetometer. The atoms are excited with a laser at a specific frequency, orienting the nuclear spins in one direction.

A potential dark matter field can disturb this direction, which is measurable.

Figuratively speaking, one can imagine that the atoms in the magnetometer initially dance around in confusion, as clarified byHector Masia-Roig, a doctoral student in the Budker group and also an author of the current study.

"When they 'hear' the right frequency of laser light, they all spin together. Dark matter particles can throw the dancing atoms out of balance.

We can measure this perturbation very precisely." Now the network of magnetometers becomes important: When the Earth moves through a spatially limited wall of dark matter, the dancing atoms in all stations are gradually disturbed.

One of these stations is located in a laboratory at the Helmholtz Institute in Mainz.

"Only when we match the signals from all the stations can we assess what triggered the disturbance,"said Masia-Roig.

"Applied to the image of the dancing atoms, this means: If we compare the measurement results from all the stations, we can decide whether it was just one brave dancer dancing out of line or actually a global dark matter disturbance."

In the current study, the research team analyzes data from a one-month continuous operation of GNOME.

The result: Statistically significant signals did not appear in the investigated mass range from one femtoelectronvolt (feV) to 100,000 feV.

Conversely, this means that the researchers can narrow down the range in which such signals could theoretically be found even further than before.

For scenarios that rely on discrete dark matter walls, this is an important result—"even though we have not yet been able to detect such a domain wall with our global ring search," added Joseph Smiga, another Ph.D. student in Mainz and author of the study.

Future work of the GNOME collaboration will focus on improving both the magnetometers themselves and the data analysis. In particular, continuous operation should be even more stable.

This is important to reliably search for signals that last longer than an hour. In addition, the previous alkali atoms in the magnetometers are to be replaced by noble gasses.

Under the title Advanced GNOME, the researchers expect this to result in considerably better sensitivity for future measurements in the search for ALPs and dark matter.

What if there are other particles yet to be discovered by scientists that are even harder to detect than neutrinos?

If such particles exist, how will their discovery affect the way we see reality? How will it affect the Standard Model, the most successful theory ever in Physics?

The game against Spurs is a must win for several reasons; we've got to put an end to our current barren run, we've got to consolidate on our top four place and at the same time, put the brakes on Spurs' charge.

If they win, the gap between us closes to 8 and they still have FIVE games in hand. Arsenal, Man U and even West Ham may also be within touching distance.

The quantum field theory on which the everyday world supervenes

The laws of physics underlying everyday life are, at one level of description, completely known, and can be summarized in a single elegant—if quite complex—equation. That's the claim physicist Sean Carroll, an SFI Fractal Faculty member and External Professor, makes in a recent paper.

Objects in our everyday world—people, planets, puppies—are made up of atoms and molecules.

Atoms and molecules, in turn, are made of elementary particles, interacting via a set of fundamental forces.

And these particles and forces are accurately—and completely, Carroll argues—described by the principles of quantum field theory, in a model known as the "Core Theory."

All the things we humans experience in our day-to-day lives—the warmth of sunlight, the gravitational pull of the Earth, the kinetic energy required to move our bodies through space—are beholden to and can be explained by Core Theory.

Don't worry that physicists will soon be out of their jobs, though.

The Theory of Everything is not yet in our hands. We will undoubtedly discover new particles and new forces, and perhaps even phenomena that are completely outside the domain in which our current understanding of physics operates.

If we push beyond our ordinary world into black holes and other aspects of quantum gravity, there are indications that quantum field theory might not be the right framework to describe them.

Similarly, it may not suffice to explain conditions in the early universe, or near neutron stars or black holes, or phenomena such as dark matter and dark energy that don't interact noticeably with human beings under ordinary circumstances.

But Carroll argues that none of the discoveries needed to explain such phenomena will alter our understanding of the physics that affects our everyday lives.

Assuming Carroll's claim is correct, it has a number of immediate implications.

It means there is no life after death, as the information in a person's mind is encoded in the physical configuration of atoms in their body, and there is no physical mechanism for that information to be carried away after death.

The problems of consciousness must ultimately be answered in terms of processes that are compatible with this underlying theory.

And while historically, discoveries of new particles and forces have spurred technological innovations, Core Theory means that won't happen going forward, since those discoveries won't be at a level to impact our everyday lives.

Carroll admits that he can't give an airtight proof for this, which would be essentially impossible.

But his arguments, he says, highlight the challenge faced by those who think something beyond the Core Theory is required. He notes that the dynamics summarized by the equation of the Core Theory are "well-defined, quantitative, and unyielding, not to mention experimentally tested to exquisite precision in a wide variety of contexts. . . .

Skeptics of the claim defended here have the burden of specifying precisely how that equation is to be modified. This would necessarily raise a host of tricky issues."

What will the James Webb Space Telescope look at first?

The first images are going to be ugly.

As the James Webb Space Telescope begins the lengthy process of aligning its 18 primary mirror segments, a question burns in the astronomical community: What will the huge observatory look at first?

Webb soared into space successfully on Dec. 25 and successfully completed its major deployments about two weeks later while speeding toward its ultimate destination: the Earth-sun Lagrange Point 2 (L2), a gravitationally stable spot in space about 930,000 miles (1.5 million kilometers) away from our planet.

The telescope includes 18 hexagonal mirror segments that need to be gradually aligned into a single, nearly perfect light-collecting surface.

A necessary part of that process is taking images of the sky to see how well the alignment is proceeding, but Jane Rigby, Webb operations project scientist, warned everyone not to expect much from the "first light" of Webb.

"The first images are going to be ugly. It is going to be blurry. We'll [have] 18 of these little images all over the sky," Rigby told reporters during a livestreamed press conference on Saturday (Jan. discussing the successful deployment of Webb's 21.3-foot-wide (6.3 meters) primary mirror that day.

Rigby was speaking from NASA's Goddard Space Flight Center in Maryland, where telescope operations are centered.

Webb team members didn't say during the press conference if they plan to release those early, "ugly" images.

The primary mirror segments will at first be off by millimeters, which is a large degree of imprecision when it comes to honing in on a distant exoplanet or seeing the stars in a faraway galaxy.

But by roughly Day 120 of the mission, which is about April 24, engineers expect that the telescope will be seeing far more precisely, with the alignment procedure complete.

"I like to think of it as, it's like we have 18 mirrors that are, right now, little prima donnas, all doing their own thing, singing their own tune in whatever key they're in," Rigby said.

"We have to make them work like a chorus, and that is a methodical, laborious process."

The next major question is what Webb will first focus its eyes on.

The observatory, billed as a successor to the groundbreaking Hubble Space Telescope that launched in 1990, has received many requests for "telescope time" among astronomers, and the vast majority of those had to be turned down.

A few "early science" programs are listed on NASA's website, but where Webb will look first has not yet been disclosed.

However, we do know some of the engineering alignment targets that the observatory will examine during early commissioning.

"We have some sources that are [of] nice and uniform brightness," Rigby said, "so we can check how the detectors are working ... A lot of those targets are in the Large Magellanic Cloud, because we can always see the north and south ecliptic poles. They're always available."

Rigby added that the team picked many of the commissioning period targets in the Large Magellanic Cloud, a dwarf galaxy relatively close to the Milky Way, because they would always be in sight no matter when Webb launched.

"We knew we didn't have to keep replanning if the launch date changed," she said.


That consistency was, in retrospect, a wise choice, as Webb's launch date was delayed repeatedly in the last few weeks alone due to last-minute issues, including a faulty data cable and an unplanned clamp band release during launch preparations.

All issues were successfully resolved before launch.

Black hole devoured a star decades ago and it was only discovered now !

Traces of a black hole 's "meal" were identified in a dataset from the 1980s, thanks to two high school students.

The object devoured a star, which was torn apart in a process known as a tidal disruption event, before crashing to the event horizon never to return.

How black holes feed

A black hole's “lunch” is not a discrete process; on the contrary, it is a confusing and troubled event, which releases large amounts of radiation.

When the star (or anything else unlucky) gets too close to the object, gravity pulls on it with violent force.

Despite this, the star still has a long way to go before reaching the event horizon — the critical point of a black hole from which nothing, not even light, can escape.

Therefore, the star's matter is gradually stripped away, until it is spaghettied.

This stellar mass "spaghetti" begins to spin at great speed around the black hole, producing a burst of light. And while astronomers have seen this phenomenon occur a few times, few of these cases have relied on radio observations.

Black hole meal found by teenagers

Young Ginevra Zaccagnini and Jackson Codd were reviewing data collected by the Very Large Array (VLA) in New Mexico and noticed that a bright signal seen in the mid-1990s had disappeared in 2017.

They left a note for scientists about the discovery, and so a team of astronomers began looking for other observations of the glow, cataloged as J1533+2727.

They soon discovered that another radio telescope, at the Green Bank Observatory, Virginia, USA, had detected the same object before its sudden disappearance.

With the sum of the data, they realized that observations between 1986 and 1987 showed that the object appeared even brighter than those of the 1990s.

Now, according to the team's calculation, the glow is now 500 times darker than it was at its brightest.

Looking further, they concluded that the glow was caused by a black hole feeding on a star, causing a tidal disruption event that resulted in a relativistic jet, detected by radio signals.

According to Vikram Ravi, an astronomer at the California Institute of Technology (Caltech) in Pasadena, "this is the first discovery of a candidate for a relativistic tidal disruption event in the relatively nearby universe."

This could mean that this phenomenon may be more common than previously thought.

These glows emitted during black hole meals are great opportunities to study them.

More than 100 such events were found in all. The paper describing the research has been accepted for publication in The Astrophysical Journal.

Galaxies, Types of Galaxies, and Constellations

Image of the Antenna galaxies, composite from ALMA and Hubble observations !

The Antenna galaxies (also known as NGC 4038 and 4039) are a pair of colliding spiral galaxies with highly distorted shapes located about 70 million light-years away in the constellation of Corvo.

This image combines ALMA observations, taken at two different wavelength regions during the observatory's initial testing phase, with observations taken by the NASA/ESA Hubble Space Telescope.

The Hubble image is the sharpest image ever taken of this object, making it a milestone in terms of resolution.

ALMA observes at much longer wavelengths, which makes it much more difficult to obtain images that are comparatively sharp.

However, when ALMA's network is complete, your view will be ten times sharper than Hubble's.

Most of the ALMA test observations used to create this image were taken with just twelve antennas working in unison - far fewer than those that will be used to make the first scientific observations - and situated very close together.

Both factors contribute to making this new image just a foretaste of what is yet to come. As the observatory grows, the sharpness, speed and quality of observations will increase dramatically as more antennas become available and the network will grow in size.

Despite this, this is the best submillimetre-wavelength image of the Antenna galaxies and opens a new window into the submillimetre Universe.

While visible radiation - here shown in blue - shows newborn stars in galaxies, the ALMA image shows something that cannot be seen at these wavelengths: the clouds of dense, cold gas from which new stars form.

The ALMA observations - shown here in red, pink and yellow - were obtained at specific wavelengths of millimeter and submillimeter radiation (ALMA bands 3 and 7), calibrated to detect carbon monoxide molecules in the hydrogen clouds (which would be otherwise invisible), where new stars are forming.

Enormous concentrations of gas were found, not only in the hearts of the two galaxies but also in the chaotic region where the collision is taking place.

There, the total amount of gas amounts to billions of times the mass of the Sun - an extremely rich reservoir of material for future generations of stars. Observations like these will be vital to understanding how galaxy collisions give rise to new stars.

This is just one example of how ALMA reveals parts of the Universe that cannot be seen with a telescope operating in both visible and infrared.
