Why do we see visuals when we meditate?

>>9047486
I'm pretty sure the question here is why do /you/ see visuals when you meditate.

Meditation is clearing your mind and quite literally focusing on nothing, to allow for a brief sense of peace and allowing you to concentrate on either your next tasks or more complex tasks as there's less going on inside your head that would affect your mood. You're not supposed to see anything, because anything and everything should be gone. At the very most, you should be focusing on a single basic stimulus, like breathing.

And why is this on /sci/?

You guys are idiots and obviously know nothing about meditation

Some time ago I made a thread about the alleged Schumann levitator (Pic related) and asked wether or not it would work
https://boards.4tan.org/sci/thread/8954365/
Mostly it was said it would work but would be really inefficient.

However recently a new thing came up during some discussions, gravity shielding.
http://mysteriousuniverse.org/2016/04/the-weird-tale-of-the-man-who-discovered-gravity-shielding-ufo-like-technologies/
Just assuming this guy is not bullshitting you can reduce the mass/decrease the effect of gravity by taking "rotating ceramic superconducting disc" by 2%. Now again this seems pretty inefficient if it works at all it tells me you just need some finetuning to make it viable (just look at how much computers have improved over the years).
Furthermore something I recognized is that the description of the gravity shield and the Schumannlevitator is pretty much the same. you just have to replace the aluminium disc with a rotating ceramic superconducting disc and got the same.
Basically my question is if it would be possible to combine these two things, and wether or not it may could increase efficiency of both making it viable or would it hinder one another.

And if someone is interested in what all this is about:

A complex apparatus with a lot of room for uncharacterized systematic behavior should be treated as experimental error first and foremost.
>>
>>9047026
If it works, it would seem to me that current theories of gravity are not only wrong, but WAY wrong.

Just invent Cavorite and use that, would seem easier.

I'll keep this short as I can. I've got a hereditary predisposition to skin cancer. I've had pre-cancerous melanoma removed from my back about a year ago, and I had a small sore on the tip of my ear that my dermatologist said not to worry about. Well, it had been there for a year and I recently had a biopsy of it done. Took a while for the doctors to get back to me, and they said that it was in fact cancer. Okay, no big deal, right?

The thing that has me freaked out is that they didn't know what they were looking at, and sent the samples to a medical conference- and no one THERE knew what the hell it was, or what to really do about it. They then sent the samples to UC of san Fransisco and I should be getting a call this week to figure out my next steps. When I asked about if it had metastasized, my doctor said to "take that off of my plate for now" and any other of my questions were just met with her saying stuff like "it's just really abnormal and we don't know what it is, really."

I'm losing my fucking shit here guys. Are any of you in the medical field? It seems like she wanted to tell me more, but couldn't. Am I fucked? How common is it for pathologists to not have any fucking clue what's going on in cases like this? I'd rather not fucking die of skin cancer just yet, I'm in my 20's and I've got shit I wanna do first. I don't normally post on this board so forgive me if this is an inappropriate thread topic. I just could use some reassurance or facts to help me to stop freaking out over the unknown.

Well, Melanoma has a 98 or 99% survival rate, but that's generally due to it being topical so early detection is common. Early detection being the most important factor of cancer survival (especially if surgery is needed). That being said, it's extremely unlikely it has metastasized, as it would have to make its way through your subcutaneous tissue, basement membrane, and into the bloodstream or lymphatic system. I feel this would be more identifiable in a melanoma, also would probably lead to pain while it is occurring. When people say they "don't know what it is", that's not nearly as scary as you think it is, as there are hundreds of types of cancers and they are just unable to fit it into a neat category that already exists.

I really wouldnt be worried, mainly because melanoma isnt a big deal anymore, and you have been aware of it and taken steps to identifying its risk.
Overall, i highly doubt this will lower your lifespan, may just be an annoying inconvenience for you

Alright, that helps a bit. I really don't care if they come to me and say something like "hey, we're gonna need to lop your entire ear off". Good! Do it!

I just worry a little because it's on my ear. That's got a pretty good blood flow and is close to shit like my CNS, brain, etc etc.

I haven't felt any pain anywhere else and there's been no real medical issues that would make me think "hm, that's not usual." So I guess that's good. I just keep jumping to that 18% survival rate if the melanoma has metastasized and my life starts to fucking flash before my eyes. Their reluctance to tell me anything more than the fact that they don't know what it is also has me on edge.

150k in debt later and my "Doctorate" is fucking useless because the field is saturated as fuck.
Fuck off with the stem shit. Its been over for a decade now.

How is it for the other /sci/entists?

How on earth can it feel like I was in the dream world for like a year, when I only slept for a couple hours?

It's beyond my comprehension.

>>9050248
perception of time is a neuronal function. there are some circuits inside your cortex, hippocampus, thalamus, whatever that mediate it. during sleep, they get falsely activated, or falsely synchronized, giving you that illusion.

>>9050267
I wish I could explain it better than this but I think it hits the mark (not that I really have studied neurology).

How many folks here have also spend a year in the dreamworld? I actually haven't, but I know at least one friend who claimed he was back in high school for a full goddamn year.

My own experiences differ in that I typically only run around for minutes at a time, but somehow I get fooled into thinking I was *always* in the dream world, no matter how absurd my surroundings are, relative to waking life.

The only time the spell is broken is when I ask myself "How did I get here?" and it becomes so obvious I'm asleep, and I'll basically wake up on the spot. Infrequently occurs to ask the question, though.

Can /sci/ create a simple meme to fully disprove Flat Earthers?

I was thinking along the lines of constellations, however they already have Southern hemisphere science deniers. Travel times over their warped land masses would be interesting, however it would have to be explained simiply for these people.

Keep in mind these God fearing people already believe photos of Earth from space are fake, and they can't grasp that the horizon is relative to your height.

All you really need to do is put your IQ scores on your resume. Once your employers know that you're well above 180, they will hire you immediately. Degrees are a meme for sub-180 IQ brainlets.

Whaddya mean? Because most schools that offer online degrees make no distinction between them and their regular degrees.

what's that pic from, roald dahl autobiography?
>>
>>9049606
Yes. Yes it is. I used to read it fairly often as a kid.
Did you read Roald Dhal too?

Which one is more ideal /sci/? Let me give an example:

1. (PERSONAL) You study 4 topics during the summer, reading textbooks, completing exercises until you're confident in your grasp of the subjects. Note that only you are aware of your grasp.

2. (DEMONSTRABLE) You study 1-2 topics during the summer, but program an algorithm that demonstrates your competency in one of the topics, showing others your grasp and further enhancing your own. Note that you now do not study the other 2-3 subjects you could have.

What do you guys think?

Do you think there's some tiny truth to physiognomy?

I know this is a pseudo-science, and that phrenology went full retard on it by explaining your personality traits by the bumps and crevices in your skull.

But don't you think the way a person looks can be deformed, altered, changed by the way it feels? By what it's lived?
I mean you get scars when you grow up. It's a bit simplistic, in my opinion, to only see the skin-deep scars and not examining the impact of some more in-depth trauma on your physical body.

In extension, you could say the way a persn thinks can be reflected on your face. It's been proven it's got an impact on your stance and your poise after all.


I know I'm just shooting the shit here, but I'd like to hear what you guys think.

Yes, and not even tiny. For example many neurodevelopmental disorders come with distinct facial features. Your brain and face do develop together and there happens some kind of interaction between the genes coding those two. Also certain racial features can hint about neuropsychological traits of that said race. Hormones like testosterone also affect both your face and brain.
>>
>>9048649
Yeah, that's exactly it. But how do you conceive it's not more widely accepted? I mean the collective unconscious hasn't really processed this concept yet, at least from my point of view. You can't yet assume people's traits by looking at them and be taken seriously at that. The natural reaction is to dismiss these kind of thoughts by thinking it's prejudice against a person - even though you could say everyone does it all the time, in seduction, in job interviews where you know what to expect from the first look at the person...

How? Why do we restrain from thinking that if a man looks dangerous, or looks dumb, he actually is? This can't be just a social construct. Spirituality maybe? Are there proper counter-arguments to this kind of thinking?

The race thing could be a bit more cautious though, connotation and all. But I'm not picky.
>>
Another question: do you think it could be valuable as a research subject? If not outright scientifical, at least philosophical or sociological?

Or has it been researched already?
