There seems to be only one video on youtube about this posted 3 days ago
Wonder if I had come across this when I was falling asleep on the smart TV.


Dr. Ryan Ridden. He's listed on the published paper "Ryan Ridden-Harper"

6:30 "I've been working with the creator of the timescape model Professor David Wiltshire
and two Phd Students Zach Lane and Antonia Seifert to test this question with supernova"

Dark energy always struck me as a kludge when observations didn't match their model, they just invented something to explain it. Something undetectable and thus unfalsifiable. Unfalsifiable things are generally bad theories.


Some imperial British dude with a pith helmet calculated the mass of Mount Everest around 1910 by using a plumb-bob and seeing how far it was pulled sideways off the vertical (by Everest's gravity) when he suspended it in the vicinity of Everest.

Yeah I never understood it myself. I'm just an innocent bystander catching all the info.
I do admit that the timey wimey stuff as a whole is trippy. Just how say one being
can be residing in a higher mass density slower time region the perception would
be for every 1 year that passes for it the time here would be 10 years have passed.
As an example. Like the Black Hole event horizons and time slowing.

Then add to that, which I haven't touched upon yet, the time perception of an organism's metabolic rate.
The reason time passes slower when we are young and have a higher metabolic rate and as we get old
time just goes by like a snap of finger as metabolic rate slows.

Makes the brain just wanna explode sometimes

You know I don't remember if I knew that our system
resides in a local hot bubble. This Nasa news

Interstellar Tunnels Found Connecting Our Solar System to Other Star Systems
They just happened to drop that bit of information about the bubble before
touching on the tunnels.

Voids and Bubbles

Don't be fooled by the channel name. It's pure bullshit.

"Welcome to NASA Space News, your daily premier source for space exploration, innovation, and astronomy news and updates. We are an independent American news agency that covers the latest discoveries, missions, and events in the field of space science and technology. We are not affiliated with NASA or any other space agency"

One reason I read, rather than watch videos, is because I know who wrote it, when they published it, where it was published, which publication editorial board peer reviewed it, and what data and citations back up what they are saying. Who is narrating that video? Who wrote the script? Where are the citations to back up what they are saying?

I am very skeptical of any "pop science" stuff on the internet coming from people I have never heard of, not affiliated with any academic organization. There are tons of videos out there with people saying whatever they think will get them clicks and money, or just crazy nonsense they make up, and no peer review or other process to ensure what they are saying is accurate.

I could watch videos like this, but at the end, I am left wondering how much they just made up out of thin air, and I realize it's a waste of time.

The information is legit for both the Local Hot Bubble and Tunnels

Aims. We aim to extract spatial and spectral information from each constituent of the SXRB in the western Galactic hemisphere, focusing on the local hot bubble (LHB).

"we found tunnels of dust cavities filled with hot plasma, potentially forming a wider network of hot interstellar medium."

Space can surprise even those who spend their lives studying it. People often think of our solar system as just a few planets and a bunch of empty space.

Yet new observations suggest we have been living inside a hot, less dense region, and that there may even be a strange cosmic channel connecting us to distant stars.

After years of careful mapping, a new analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant constellations.

Astronomers from the Max Planck Institute recently confirmed it using data from the eRosita instrument. Dr. L. L. Sala, lead researcher, and colleagues shared these findings in a paper published in the journal Astronomy & Astrophysics.

EDIT: Ugh forgot to add that the video has the link in their description for the Astronomy & Astrophysics article link I posted below as well.

Well that's good. But you are still relying on the person reading the study for you and getting the results correct. Effectively there is a middleman who may or may not understand what's in the paper and all the background info it relies on. But a citation is a good start. Just saying I don't trust videos by people with no credentials.

If you want to have some fun, look for videos explaining the twin paradox without using acceleration (special relativity only). I have found them in the past, contradicting each other.

Now we might have Negative Time. In all probability. Probably.
On the quantum scale at least.

And Thank god the guy was smart and showed the actual
University of Toronto research paper in it.

[chuft]

One of the reasons you can't send information faster than light is because there are scenarios where the information could be received before it is sent, which obviously makes no sense since it violates the laws of causality.

Interestingly, photons have no mass, and time does not exist for them. Which is pretty weird. A photon emitted from the Sun and absorbed by a planet 2 years later is emitted and absorbed instantly from the photon's point of view because photons have no point of view - time is something only observed from inertial reference frames, and photons, with no mass, are not part of any inertial reference frame. This is why they are viewed from every reference frame the same way - traveling at speed c - even to an observer traveling fast in the same direction.

None of this quantum stuff really makes any sense at the macro level that we exist at.

Exactly what I commented to someone. I don't know how this translates to the macro scale.
That quantum aspect always seemed odd to me that it's the fundamental building blocks of everything
,of the entire universe, we are looking at and yet it doesn't affect the macro scale in anyway.
Unless, what they've observed in this case is such an uncommon probability. Wouldn't have any
noticeable influence on the macro scale.

[chuft]

Quantum mechanics affect things indirectly at the macro scale. Microwave ovens and atomic bombs are based on quantum mechanics. It's just that all the "weird" stuff in quantum mechanics is almost always not visible at the macro scale. Somebody did make a device where you could see quantum effects directly at the macro scale.

Not easy to do.

But I forget, you like videos.

Consciousness involving Quantum Physics

Go to 8:07 for the heart of the explanation

The Smart TV youtube app began recommending Consciousness videos for some reason last night.
I tend to like following certain youtube video rabbit holes. The other videos
were more philosophical than actual biological mechanisms. Then I began
to remember I had seen the above video a while ago. Sure enough I did.
Not at bed time though but when working or playing on the computer and the laptop
playing stuff in the background as usual while I'm on the desktop.

[boredjedi]

It's all very weird I gotta admit that

[chuft]

Since consciousness is subjective and can't be measured, I tend to immediately write off any "scientific" explanations of it, since science deals in what can be measured.

[boredjedi]

I put a time stamp in the post 8:07 the meat of it
