Q: Is it true that a black hole isn't a hole at all?

Watch a TV show on this fact.

'Black hole' is a characteristical term used in English, earthy language. angel

 

It is resemblance of happening in the Universe ..., i.e. strong gravity that nothing can escape ...

 

'Black hole' in Universe and 'black hole' on golf course are two very different things ... 

 

I guess, TV is assembled in the framed hole ...

 

I prefer to watch washing machine's cycles over the TV ...

Why you asking people on here for? People on here can barely figure how to get a visa for china let alone how a black hole works.

Any question I guess is fine, just curious why? I mean its like if i went to cooking recipe website and asked them how to change the transmission in my car.

Antarctica's Spooky Cosmic Rays Might Shatter Physics As We Know It

 

Something strange is happening above the frozen landscape of Antarctica.

When scientists launched a science balloon mission called the Antarctic Impulsive Transient Antenna (ANITA) over the continent in 2006, a cosmic ray pinged off one of its instruments. That isn't so strange. Cosmic rays fly from deep space all the time, and ANITA can detect them and measure their energies. But on this occasion, the cosmic ray didn't come from above, it came from below. This high-energy particle had emerged from the ice and traveled upward through the atmosphere. That's not something that cosmic rays are supposed to do.

During another ANITA flight in 2014, it happened again.

Cosmic rays come from some of the most energetic places in the universe — from supernovas to the swirling maws of black holes. To see a cosmic ray emerge from the earth suggests that this particle traveled from deep space and passed right through the planet before emerging on the other side. According to physics, however, this is impossible.

The thing with cosmic rays, which are high-energy protons and atomic nuclei, is that they have large cross-sections. In other words, they have no problem interacting with matter. Should a cosmic ray hit the Earth, it will be stopped in its tracks by the atmosphere, like a bullet hitting a cinderblock. Conversely, neutrinos have very small cross-sections, meaning these ghostly particles zip through matter as if it weren't even there. Neutrinos are so weakly interacting with matter that trillions of them pass through our bodies unimpeded every second. But the particles that ANITA detected were not neutrinos, they were (what appear to be) cosmic rays, and they passed straight through our planet as if it weren't even there. Frankly, these cosmic rays are not normal.

Now researchers have revisited these ANITA events in a study submitted in September 2018 and found three similar detections of upward-moving cosmic rays in another Antarctica experiment called IceCube, a particle detector that's buried in the ice. They've arrived at an astonishing conclusion: These aren't regular, Standard Model cosmic rays; they could be evidence of exotic physics.

Exotic physics refers to physics that we don't currently understand, and scientists refer to it as "physics beyond the Standard Model." The Standard Model is a recipe book of sorts that tells the universe how subatomic particles (from electrons to photons to quarks) should behave. When the Large Hadron Collider (LHC) discovered the Higgs boson in 2012 — the particle that endows matter with mass — the Standard Model was complete; the theoretical framework that describes all interactions down to subatomic scales had been wrapped up.

There was, however, a problem. In fact, there were several. The Standard Model does not explain what dark matter and dark energy are. It also cannot explain why the majority of the universe is made from matter rather than antimatter. There's also the question of neutrino mass — the Standard Model falls short there, too. There are many mysteries that cannot be explained by the Standard Model recipe book, so physicists are hard at work trying to find evidence for a recipe book that's governing the universe in the shadows.

Maddeningly, the most complex experiments on Earth have yet to find any conclusive evidence of this shadowy realm, though there are clues. And, according to the researchers investigating the ANITA and IceCube anomalies, these cosmic ray detections may have opened a window into physics beyond the Standard Model, providing evidence of particles that look like cosmic rays and yet don't behave like cosmic rays.

"[U]nder conservative extrapolations of the [standard model] interactions, there is no particle that can propagate through the Earth [...] at these energies and exit angles. We explore here whether "beyond the Standard Model" particles are required to explain the ANITA events, if correctly interpreted, and conclude that they are," the researchers write in their study.

"Supersymmetry" (or SUSY) is one hypothetical exotic physics recipe book that may help explain what's going on. This hypothesis suggests that all the particles we know and love have SUSY particles (aka "sparticles"). These sparticles would provide balance to the Standard Model and may explain some of the mysteries that are confounding physicists and cosmologists. Could these phantom cosmic rays actually be a whole different type of particle emerging from supersymmetry?

It's too early to tell, and more data is needed, but it's tantalizing to think that we may have accidentally glimpsed physics beyond the Standard Model at the most extreme location on Earth.

People online are pointing to this and talking about parallel universes and things. I don't know enough about that to put forward any opinion but imagine if it turned out to be true.. like 2020 wasn't a hell of a year already.

That was posted at Zero, first! Parallel universe, where time goes backward ...

 

I was laughing at the comments ... there,  when I was suddenly 5-years old ... again. 

Here it is:

https://www.zerohedge.com/technology/scientists-discover-evidence-parallel-universe-where-time-flows-backward

 

I saw the same article at the Oz News, butT ... only on the next day.

 

I fancy the topic 'cause Earth's physical laws don't apply elsewhere in universe ...

However, it's kind of heavy topic.

 

Universe is too big for humans to be the only one ... IMO, so whatever will come it will come.

I am simpleton and not scared easily. I can laugh even at the rainy weather ...

If you look at the animals, who are all no.2 comparable to primates ... one nice sunny day, the wheel might turn ... and primates will take no.2 spot, after the big shinny UFO's landing ...

Moreover, it might landed LTA and we are all unaware of manipulations ...

When I was DD-ing Gobekli Tepe, I came across some read about the real purpose of Gobekli, i.e. why and by whom it was built 11 000-years ago, and one 'option' was ''advanced outer space civilization built it for directing/sending waves to the home planet in other galaxies."

Apparently, since they lack of sun there, all their energetic needs come from the gold (metal), which was in abundance on Earth ... I read also about some reasons of destroying today's Syria, Iran & Iraq, i.e. Mesopotamia. 'cause advanced civilization left proof of landing ...

Key word was 'Annuaki' or something similar.

Some Syrian's artifacts are describing it in ancient language ... written on papyrus.

Russians-did-it denial of parallel universe with the time flows backward ...

 

https://www.rt.com/news/489519-no-parallel-universe-antarctica-time-backwards/

 

What was surprising about the findings was that, even as early as this month, a Russian study had results which indicated“that high-energy neutrinos are born in active galactic nuclei.” So, the fact that ANITA detected a handful of neutrinos coming from inside the Earth’s interior runs directly counter to our current understanding of the origins of these particles. This led to excited reports of a parallel universe to our own.

The possible existence of parallel universes came into being via quantum physics, a theory in physics that attempts to describe the fundamental properties of nature at an atomic level. Examining physics at this scale has birthed many strange discoveries over the years. If you shoot a single electron through a double slit, for example, you will know only the likelihood of where it will land, not the exact location, leading to theories that would usually be thought outside the realms of possibility.

Quantum physics is something I can't wrap my head around but I like reading about some of the trippy studies that are being done, it makes me pretty sure we know nothing about how things really work.

 

Did you ever read about that two slot experiment you mentioned? That's a real head scratcher.

A:Going to HK would be the best bet I reckon, especially if you were looking for a church wedding. Chinese weddings are pretty grim IMO - you go to a barren govt dept with souless officials and navigate red tape so some guy can give you a red stamp and a marriage book. You get expensive pictures taken of you both posing in places you'd never go to in everyday life that is somehow supposed to represent your wedding, then a while later it's off to a restaurant where a game show host kind of guy makes sure it's as tacky as possible while the guests eat as fast as they can so they can leave as soon as they finish eating and gave you money. Hell, I'd go to Thailand or the Philippines and get married in Paradise.   -- Stiggs
