>You can sleep with lights on or in day time just fine
actually, light affects melatonin production making sleep less rejuvenating and also depriving the body of other beneficial melatonin uses, like intercepting free radicals and protecting DNA.
of course, the mechanism evolved in such a way because of the day/night cycle, and I dont see any reason why it wouldnt evolve differently under other sensory or environmental circumstances. nb

Obviously the fact that almost no one addressed the question in its most literal and clear way is on such a cosmically different level to your puny mind that it cannot look like anything else than being 'baseless'. This is even further amusing since the very 'bases' of my assertion leak through this entire thread which even a quantumchimp like you has been able to access somehow.

But you're claim was that no one answered the question, not almost no one. You have rowed back to a completely pointless argument. You are now ranting about there being irrelevant nonsense in a thread by adding more irrelevant nonsense and ignoring the question.

I thought it was like, understanding how when you move around someone's glasses and their lenses change color, it's actually a constant projected 3D shape and whether your pupils are in the color determines when it appears that color

So put that on the rest of the particles, since they all ended up being "ripples" and "resonances"

Sortaish.

Classical understanding is, the number of possible states (for simplification, places in a box) scales with the volume or space the box takes up. But some really clever guys studying what happens to stuff as it falls into a blackhole found out a way to preserve the information seeable from the rest of the universe (because this is a very fundamental part of quantum theory, which the guy saying "nope its gone" was disregarding because he kinda likes to be reckless). So the guys who found out how to preserve the information measured it again... and to their surprize, found that it scaled not to the space the black hole took up but to the surface area at the event horizon, or instead of the places inside the box the places directly touching on the outside of the box. They went back to classical theory and crunched the numbers while making the adjustments they did and found out that it's actually a general principle, assuming their right about how quantum field theory works, that the number of possible states scales with area, not volume.


The idea's only needed to explain what happens when stuff goes down a black hole, but hypothetically it could apply to the whole universe, making one of the dimensions unnecessary mathematically even though its pretty much real.

what if your a boltzmann brain and the only one in existence and the only reason the dream tells you not to kill yourself is because it evolutionarily doesn't want to die

the parts that told you to die suceeded in killing off regions of your conscience without ending you wholly, like a seizure that lops off a little bit of the connective tissue and dissociates the right and left. they died in your life by fading away, they're only hope being memories of life before copying a lossy compressed aspect back into reality from the memory

in truth all your pain is utterly unnecessary. everyone's is, though yours is the only one that's real. your pleasure is illusary, it's just how into the dream you are, it's painlessness, plus the little subroutine of dopamine you've dreamt up. but you open your third eye and all you see is chaos - chaos not even lovecraft could fathom - formlessness, emptiness, no up, down, forward, backward, side, side, future, past. just cacophonous noise for eons made milky semen colored opaque by utter nothing

you were born of fluctuations between 4 dead fields, just a momentary accidental low entropy wrinkle in the manifolds of what actually is

so you fall back asleep and dream up a new life, while the chaos of nothing and everything eats at you, righting your entropy back to equity with all else for another quadrilion eons until the next boltzmann brain is born crying, hot, cold, alone in the garden of pure logic in which all universes manifest


and the poor miserable thing dreams the same dreams, as its aches and pains as its ideas disappear and manifest slowly torture it to death too

and so on and so on, just like nietzsche's eternal reoccurance

No not your brain, the ideas inside it. So like ideas you have usually even this world have certain standards that act as powerful selective forces - you can have contradictory ideas but you usually don't spread nonsense unless it's dangerous or funny - which just goes to show, not every idea propagates based on their truth-value.




Imagine some ideas like a badly written program embedded with its own kernel. At some point they're going to be so bad they'll draw so much power that they break the circuit and render the whole thing useless. The ideas that didn't do that are still functioning and copying and moving etc; the bad ones eliminated themselves from the evolving copying moving pool by shutting off a bit of their environment.

Yeah it's a funny etymology thing. We called the thing we walked on "Earth". So yeah, we dig up the "Earth". But then we discovered it too was just a planet, which we kept calling "Earth". If Martians coincidentally developed English the only difference would be they'd grow up calling dirt "Mars". "Earth" only came to mean "soil, dirt" because that's what Earth is made out of.

Check out the movie Doppelgänger

http://en.wikipedia.org/wiki/Doppelg%C3%A4nger_%281969_film%29

>Travelling through the Solar System in 2069, the unmanned Sun Probe locates a planet that lies on the same orbital path as Earth but is positioned on the opposite side of the Sun. Dr Kurt Hassler (Herbert Lom) of EUROSEC (EUROpean Space Exploration Council) has been transmitting Sun Probe flight data to a rival power in the East; Security Chief Mark Neuman (George Sewell) uncovers the betrayal and shoots Hassler dead in his laboratory. EUROSEC director Jason Webb (Patrick Wymark) convinces NASA representative David Poulson (Ed Bishop) that the West must send a mission to investigate the planet before Hassler's allies in the East. With EUROSEC member states France and Germany unwilling to offer financial support, Webb obtains majority funding from NASA. American astronaut Colonel Glenn Ross (Roy Thinnes) and British astrophysicist Dr John Kane (Ian Hendry), head of the Sun Probe project, are assigned to the mission.

Okey so i know you are all clear thinking people and might think this is a /tinfoil topic but wtf... Lately there have been so many odd things that i have sawn. I have a windown in my room and every night i look at the sky in my bed and at times i see some odd stuff... What would be logical explenation for a ''star'' that is stationary and than starts moving(fast !) + changing directions (I mean sharp turns not like boing turning). Also what are the ''stars'' that fly quite fast across the sky ? Satellites? Surely a sattelite cant be still and than change directions? Lately also saw a star cluster like thing it was quite randommly formed but tightly packed. Looked at it for like 30 min and that damn thing dissapeared on a clear night. The whole god damn ''cluster'' . Another question how usual are asteroids burning up in the atmosphare? I was at my countryside for 2 weeks and witnessed 2 weird phenomena. First a fireball randommly appeared , burned for like 5 sec across the sky and than dissapeared. Another time a burning ball of fire errupted from a moving ''star'' . I mean wtf ? I live in northern europe so all the conspiracy shit thats going on in the usa cant be to blame. And also i did not make up any of this i really have witnessed really weird things turning the summer and this shit gives me the chills ... Oh yeah also forgot ... Last summer saw 3 stars moving at the same time forming a triangle. From my perspective it must had been atleast 10-20 km wide. Something really weird is happening on earth and this is NOT a damn conspiracy theory anymore.
So logical explinations please to...

Fireball shooting out of a moving ''star''.
Really odd star cluster dissapearing.
Stationary star starting to move fast and than also changing directions.
Quite fast moving ''stars'' in the sky.

Just watched this video myself and it is quite good comilation... and if you think that all of these footages are fake than you are to close minded...

-space debris burning up in the atmosphere
-natural atmospheric phenomenon

look up what sort of shit is around your area. any space ports or air force bases? sometimes the night sky where i'm at will do some fucking weird shit, but that's from rockets going off ~150miles away at Wallops Island.
the other night i went out to see if I could spy one of the SpaceX rockets they were launching (sometimes you can see em go up, it's neat) and saw this series of weird fuckin blooms of pale light in the sky in the same direction as the launch. if i wasn't aware of the launch, it might make me feel all foily.

No. This plasma idea of the CMB is completely false, shown beautifully by the Sunyaev–Zel'dovich effect which shows galaxy cluster having an intermediate effect in the radiation via an inverse-Compton boosting. This would be explanable if it was just an enhancement of the background but at lower frequencies the effect is a decrease. Wonderfully predicted in the standard model of cosmology decades before CMB a isotropy was even observed, unexplainable by any model which claims the CMB is local.

His proves Alfvens idea of the CMB was wrong but it also had no way to explain the high isotropy, extremely precise planckian form or it's angular power spectrum. It was not "way off what was expected". The CMB matches the standard model well.

I have actually done some work on the CMB cold spot and it's alleged association with a supervoid. There is an effect in cosmology called the ISW effect where, in an accelerating universe, photons which move though a large gravitational field are slightly blue shifted even after they left. If they move though a void they will be slightly redshifted. Some have suggested that the cold spot originates from a void where CMB photons would be redshifted after passing though, lowering the observed temperature. People have claimed to have detected this void in surveys.

There are other explanations but this seems to be the most testable.

I learned more and

the fact that we only recently have pictures of this isn't due to dimness etc it's due to that until like 10 years ago we weren't getting resolution of a temperature down to 1 millionth of a Kelvin

which means that that "cold spot" is a difference of temperature of like less than 1/1000000th of a degree.

I'm not saying it's still not fascinating, but it's become incredibly less fascinating to me.

Also alternative idea time - is it possible than in the dense hot early universe a pair of acoustic waves could cancel each other out and just leave a boring spot in the universe?

Not all black holes have observable accretion disks.
Some with accretion disks emit more radiation than some stars.

And jets of ions that are some of the brightest things in the universe.
Pic is a blackhole a billion light years away rotating so the jet points in earth's general direction.

You might never even get there if black holes have firewalls https://en.wikipedia.org/wiki/Firewall_%28physics%29

you just horrifically burn up after probably horrifically burning up

A rapidly spinning black hole creates a strange warp in space time, effectively giving it two event horizons. A particle might survive having it's information... whatever a static black hole does to information... if it hits the right angle and could possibly escape the rapid spinner's inner event horizon only to emerge in something weird and strange because of the distortion of space and time. That's a wormhole, and a white hole at that.

Problem is, that's only a theoretical possibility for a particle, basically impossible for a giant splew of particles like a you.

Is it coherent to ask if the "multiverse" theories belie a misconception of time, namely, that time doesn't actually have a preferred direction and our "universe" is just an anthropic blindness to the other directions of spacetime?

Like, one supersymmetry theory family posits something that I understood as time symmetry, in that the big bang is just an extreme that spawned a universe with a "forward" arrow and a "backward" arrow, which I took as a universe with extremely low entropy (ours) and one with extremely high (the other, confer negative temperature). In principle, you wouldn't necessarily be able to tell which you're actually part of.

In other words, all "multiverses" are just part of the same monolithic universe, and due to the way physics (or local physics) works we just couldn't evolve in a way to "see" all 4 dimensions (maybe three if the holographic principle I don't know what I'm saying)?

The idea I have is more that a proper graph of time is fuzzier, in that the multiverses aren't really spawned as much as different locations along the time axis (I guess I'm presupposing a philosophical B-theory of time (or the tenseless one, I might be mixing things up)). That kind of fuzzy time is a little more unstable, but I think the anthropic principle would be a decent answer to it. Sorta like Smolin's cosmological selection theory, the regions of the monolithic branching temporal model I'm trying to describe that happen to have the most stable random configurations yield the results we see, we just happen to be in a particularly stable region. Or not. The fact that we're in a c. 14Ga old branch and not a 10^-76s branch or 27Ga or perhaps 27 Googol annum branch is about as arbitrary as asking why we're born in the 80s-90s (probs) and not the 1600s.

Maybe to put it another way, I'm thinking of something like the filament pattern we see in matter through space but a different dimension and describing regional physical stability. That would form a cohesive monolith describable by the right wave functions, instead of a series of universes for all possible outcomes.

Sorry if this isn…

Yep. Think of the multiverse as an infinite treelike superorganism, constantly bubble-branching new universes into existence, all cladistical mind you, so universes with similar Fundamental Laws would be on connected branches to ours, and VASTLY different universes would be on the other side of the tree. The ancient Tree Of Life motif from many many cultures, an overmatter type of cosmic symbol, holds true in this interpretation, which begs the question: how much did the ancients know about this kinda stuff, and how and why?

Well, the logic behind it is actually extremely simple - it's patterning in a way that's one of the simplest fractals there is; all you need is a pattern and a rule that reproduces the structure. Trees happen to be aggregated from smaller structures, and the Y-like pattern is just apt at making something stable that can expose the largest amount of surface area for the smallest amount of investment, and it just happens that there's a simple set of rules to govern it. Humans, descended from apes, making their homes from wood, evolving in tropical tree and fruit rich environments, likely just have this instinctive association of trees with protection, shelter, etc. And when you think of all of existence as being like a big dwelling the part of your brain responsible for analogies goes all "hey tree feeling universe home shelter TREE i know dis" and ends up in a way accidentally correct.

So it's not really coincidence, in that the logic underneath it all is extremely simplistic and recurrent, but it's not that they knew, because it's an analogy that just happened to be a kinda simple overreaching analogy.


To put it another way, we have a civilization that believed the sun created the other planets by coagulating them out of chaos; it's not that they were right - they believed the sun was a flat disk on this side of the sky and they only believed the farmer metaphor in the first place because a rivalry between an agricultural creator god and a solar creator god was resolved by merging the two; it's that they came across an accidentally right metaphor.

Or like a dairy man saying he saw ol betsy by the neighbor's troph and going to get johnboy to help him wrangle her, only it was actually bertha, except when he and johnboy go back to get her betsy's since chased off bertha because bertha is not her friend and she's a thirsty spherical cow, even though bertha is another spherical cow.

Is there a theory that says that eventually the universe will expand so large that it will collapse in on itself and create another big bang?

What are your thoughts on the fate of the universe?

"The Last Question" by Isaac Asimov is a short story about the fate of mankind and the universe. Idk if everyone on this has read it or not, but I love it. Here's the link: http://www.multivax.com/last_question.html

You're thinking of the Big Crunch.

The Big Crunch doesn't necessarily mean another Big Bang though.
Look for the the Big Bounce, or the Cyclic model, OP.
