>>5364382
oh...

The fact that I'm a temporary collection of atoms, arranged in a way to perceive, integrate, interpret and transfer information. An automaton, who has the capability to know it exists and that its life is finite. That there are almost 7 billion like me on a tiny planet, and that it took 13.7 billion years for us to emerge from the simplest, tiniest particles.

When I die, almost all of the information I possessed will vanish. All the atoms that make my body will be distributed, leaving no memory of me. I am unique, and I am the only one capable of experiencing and exploring my place in the world.

It makes me feel both incredibly insignificant and important.

That elementary particles are identical to each other.

The way I see it, any "remarkable fact" ever can be reduced to the presence of some symmetry. Why are electrons copies of all other electrons? Why isn't every particle in the universe unique?

>>5364432

Confirmed in countless experiments but no one is yet to offer a single unified theory that satisfactorily explains it more deeply.

>>5364441
This!

lol'd so hard

The coldest known temperature in the universe happened on earth.

Gravity.

The fact that things pull themselves together over infinite spaces based entirely on their mass. The fact that it can warp "space", that space is even something that can be manipulated, let alone warped by gravity. The fact that it can somehow escape black holes, something which neither particles nor waves can do. The fact that it's so easy to escape with a minimum of force but could potentially pull an entire universe together.

There are three generations of matter particles, however all stuff is composed of the first generation only, the other two can be briefly seen in particle accelerators only, are seemingly useless and nobody knows why they even exist.

>>5364581

>The fact that it can somehow escape black holes, something which neither particles nor waves can do.

Charged black holes can attract stuff through electromagnetic force (photons), too. Gravity is not special in this.

>>5364348

That eveything Happens in the same pattern in rhythm, though chaos. The butterfly effect, if you'like. This effect gives "Mana" around the "room" that-when taped- breaks pattern shortly. In this break, Magic happens, and it will always manifest itself.


Ever noticed, that when two people have a fight of words, and one of them have finished an argument, that leaves Silence. A's soon as the person breaks it's frozen state, it will happen.. 'X" will happen.
I could tell you more, if not for end of worlds-in a few days... Seems pointless now. Will take to damn long, and you got better things to dó then to be teached about the universal source code.

More info?

>>5364432
I guess I can't disagree with there being a lot of symmetries on the level of elementary particles, though a lot of them aren't perfect. Weak interactions, for one, fuck up a lot of otherwise good symmetries.

That it has become conscious.

>>5364835
Also negative temperatures are HOTTER than positive temperatures.

>>5364836
It comes from the definition of temperature and plotting entropy versus energy for (finite) spin systems. The plot has a maximum, and above that adding energy reduces entropy, so you have a negative temperature.

Actually looking at the plot of temperature, it looks more like you roll over from T = + infinity to T = -infinity (if you excuse me treating the limits as numbers), and then approach 0 again.

There is some debate whether it's truly legitimate because any real spin system has to be embedded in a lattice, which will have a positive temperature.

>>5364836
He thnks in C°.
Zero degrees =/= total absence of movement (particles)

>>5364845
I believe he's talking about the fundamental leptons (electrons, muons, and tau particles) and their corresponding neutrinos. The heavier ones have finite (rather short) lifetimes, on account of being heavier than electrons.

He's not quite correct though. Taus are rarely seen because they have extremely short lifetimes, but we get muons outside particle accelerators from cosmic rays interacting with the atmosphere.

If he's talking about the quarks other than u and d, those go through pretty much the same process, decaying because they are heavier than u and d.

The chance that this universe is real and not a simulation is very very close to 0

>>5365070
fuck that, we arnt related, we ARE all vibrations in the same fundamental field.

>>5365108
Explain why.

>>5364581
Except that gravity has little-to-nothing to do with mass.

>>5365349
Well, you only have to answer this question:
Will we be able to simulate a universe similar to our universe after several billion years or even sooner? If no then the chance that we are in a simulation is 0. If yes then the chance that we are in a simulation is 1.
Why? Because if such simulations are possible, then there should already be A LOT of simulations out there. Since we can simulate, then the simulations will also be able to simulate inside them and so on. There would be so many simulations that the chance to be the real one is 1/n (n being a huge number).

But it all depends on how you answer the question. Both answers are equally possible.

>>5365649
Then that makes them 0.5 and 0.5 if they're equally possible you fucking moron.

>>5365668
That's not how probability works at all.

>>5365671
Either the universe is a simulation or it isn't. The probabilities of both sum to 1.

Retard that I quoted said both answers were equally possible.

x + x = 1

x = 0.5

You must be him.

>>5365685
I said that it depends on how you answer the question you fucking retard. It HAS to be one of the answers, don't try to play probability there. I chose "yes" because "no" is retarded. I don't even know why I said that they are equally possible.

>>5365649

Not really. Just like in games, when you slow it down it requires less computational power. Again, just like in games, we have superposition (when you don't look at it, it isn't even computed)

The Universe is alive. How do I know this? We are Universe. It is continuous. We take in material from our surroundings to add to our bodies. Likewise, we're constantly shedding atoms to our environment. In this way, you can think of your consciousness as an energy wave moving through the material we call matter. Your body is not made up of the same atoms as it was 10 years ago, but you have the same constant sense of self and the same memories. There's no difference between the Carbon in my hand and the Carbon in the milk next to me. Let this sink in, the Universe is ALIVE and experiencing its own existence. I am Universe and so are you.

Not actually true. There were a couple hundred thousand years before baryonic matter became commonplace, and there's a good chance a number of the electrons in you weren't electrons when that started, but wrapped up into some more massive lepton that later decayed.

There's also the annihilation of electrons through interaction with virtual photons that happens more or less constantly.

The energy was all there, though.

All the atoms in your body get cycled out and replaced about every 7 years.

A few million years after the big bang, the universe was actually expanding faster than the speed of light. "Why anon," you might ask, "how is that possible when the speed of light is the cosmic speed limit?" Well, shut the fuck up and I'll tell you. The speed of light is the fastest anything (including something massless) can move through space, but space itself can move infinitely fast. NASA is even experimenting with a theoretical FTL ship that moves space around itself for propulsion.

Maybe they all just watched Futurama and decided Farnsworth was on to something.

>>5369219
My thoughts exactly when I read the article. Unfortunately, more likely Futurama writers read about the Alcubierre drive and thought it would be hilarious to introduce.

>>5369219

In a funny way, that's sort of how it works. By manipulating space time in front of and behind the ship you can effectively move very quickly without actually propelling yourself.

The dark matter drive in futurama is not a warp drive.

That for all our thoughts and accomplishments, when our race is dead, it will have no impact on the universe at large. It will be a miniscule blip on the cosmic scale.

Slimemolds exist, seriously how the fuck did those things come about.

>>5369085
No. Virtual photons are fundamentally different, in the sense that they can have things like mass - wiki "virtual particles".

All the particle shit here, like electrons becoming photons and jumping around like points, is not a fair way of thinking about a "fact of the universe". Particles, waves, and even fields are just conceptual and mathematical tools for representing an enormous soup of mutually-interacting incongruities. We're nowhere near the level of sophistication needed to say that any of these are an accurate or true representation of the fundamental nature of the universe.

That said, we at least know that our universe consists of broken global symmetries (which give conservation laws), local inhomogeneities (which look like particles), and a whole bunch of interactions between everything that makes most of this computationally intractable. I'm comfortable with that for now.

>>5369246

>>5364412
In fairness to this problem, many jet aircraft will not use their jets to take off (because many jets are inefficient or even ineffective at low speeds) and may instead use a tow or track or batteries or catapult, and some of those will in fact not work on a treadmill.

The notion that an airplane typically uses the same thrust type to take off as to remain airborne is not obvious to most people, hence the confusion in the treadmill problem.

An alcubierre drive is a form of a warp drive. I'm not interested in debating common usage of words though, so feel free to rephrase my post as "the dark matter drives in futurama are not alcubierre drives or otherwise built on warping of spacetime." They actually move the universe as a whole around the ship, it's intentionally nonsensical.

The universe we live in, the planet we call home, the people we interact with, the technology we use, the food we eat, the words we say, the emotions we feel. Galaxies, nebulae, stars, mountains, wheat fields, cars, computers, baseball, billiards, love, hate, steak, chocolate, sex.

>>5369718
haha, come on bro...

>>5369718

nope

It exists!

There are two things that blow my mind about the Universe OP; one's pretty scientific and the other's mostly conjecture but could make sense until proven wrong.


The first is that, due to space expanding ever outwards due to whatever is causing it, from your perspective you are the center of the universe. This is because all points are expanding from all other points at a constant rate, giving you the perspective of being a constant (a.k.a. center) in the universe.

The second is that due to the conservation of matter and energy, neither one can be created nor destroyed. Thus, whenever entropy finally takes hold of the entirety of existence and crushes us all down and into the infinitesimal point at the end of the universe, everything would start again. Though since all the same materials would be involved, the new universe would most likely be very similar to what we have now, and I wonder why it is and what may change in the next go-around...

>>5369770
>whenever entropy finally takes hold of the entirety of existence and crushes us all down and into the infinitesimal point at the end of the universe

The idea is that the opposite will happen. You know, cause everything is expanding?

>>5369473
apparently the University of Pittsburgh has never heard of Dragonforce

The fact that it is hospitable to us.

The Universe's gravitational field is slowly but surely getting stronger, between 2 and 22 billion years atoms will start to quantum tunnel to planes closer to the ground to not use as much energy defining gravity.
For example if you put an object, any object on a table, it would instantly appear on the ground and maybe if there was a cave underground it would appear there, and so on. So either that kills us or the cooling of the universe kills us, or ourselves. Very strange thing.

It's not a sphere per se but that is accurate. There is no imaginary glass wall where the edge of space is.

It's like you're a drawing on a balloon and someone is inflating it, is space 'expanding.' You can end up where you started if you go long enough.

>>5369955
But anon, it wasn't made for us. We are here because we appeared and happened to be comfortable here.

If life evolved on Jupiter it wouldn't last long on earth, probably, whatever it would be.

>But .001% of a change in the mass of protons would mean that stars never happened or something

Well, we're fine now. Obviously we would only be surprised if we existed in a universe that WASN'T hospitable to us, since we shouldn't be existing there.

>>5370100
The big bang theory itself doesn't necessarily implicitly state that "something came from nothing" but merely that there was a beginning of space and time in our universe.
There could be other universes, or other unseen mechanics beyond that. There are lots of hypotheses, and lots of crazy ideas about this.
But the point is that Science only tells you what we can observe based on principles found in nature.
Religion doesn't play by those rules, and has been proven wrong a million times over and has receded from being seen as fact, to being at best an optional philosophical standpoint characterized by internal consistency so as to avoid getting burned again.
But just because an idea is internally consistent, that doesn't necessarily mean that it is true.
You must look at the body of evidence for a given postulate, make judgement calls about its veracity, and compare it to the world we live in.

How many people have you seen being turned into salt statues? How many times has a "prophet" stood forward, warned people that he would cast a spell, then done so, causing frogs to rain from the sky at his will - in front of cameras?
How many Sasquatch autopsies have been documented?
If these things were real, they would have been proven.

What i'm trying to say is, they're NOT equally valid unless you completely forfeit all attempts at weighing the hard evidence for one, over the hard evidence for the other, and estimate the track record of their sources over the course of history.

What you'll find is that religion, despite fighting tooth and nail, has lost again and again and again to science.
The bible used to be "Fact" to believers. Now you've got to kind of squint a little and be creative and maybe interpret it figuratively and if you ignore all of discrepancies and and and and and and ...
Basically, the scriptures should be a discredited source even if you were a christian yourself.

the fact we exist are have the illusion of consciousness

>>5370252
forgot my picture

Some research shows that when you sleep your brain releases DMT, and causes you to dream, and is also released before you die as a 'goodbye-ease-your-passing' type of deal.

Now if this is proved to be true, consider this.

Life is a trip.

What happens when you don't get 'good' sleep? Or any sleep at all? You feel like shit, you can't function. Should you experience long periods of time without sleep your body will force it on you. It being DMT.

Forced sleep or 'microsleep' will produce DMT, and death produces lots. Either way you experience a trip, so maybe life and reality is just a trip, with the necessity of sleep giving you your necessary 'fix' and just acting like a top-up for life. If you don't sleep you can go crazy and develop mental illnesses...

So /sci/, is it actually possible?

>>5370256
except DMT does more things then "makes you hallucinate man" and sleep is more then just "lol time to release DMT" otherwise you could replicate sleep with pharmaceuticals

>>5370256
This has also been used to explain afterlife visions, tunnel of light, life-flashing-before-eyes, etc, when in shock and on the verge of death the brain releases DMT, explaining 'eyewitness' accounts of the afterlife.

Except from what I understand this information is false and DMT is not produced by the brain.

If you could cite otherwise I'd be thankful, would be cool.
