Tell me about psychedelic mushrooms, guys.

Are they dangerous?

Do they have potential in the medical field?

They can be dangerous. Within the circle of people who use psychedelics it is understood that they can be used to rewire the brain somewhat. Your established perceptions of the reality you have forged throughout your life can be questioned. Some people find this an uncomfortable experience, others just let it take them where it will and yet others use that inherent ability as a tool to repair damage that has been done to their mind, or just to enhance the way they perceive life.

It's largely psychology babble and unfortunately most psychologists are more nuts than their patients.

So they have the potential to be dangerous from a psychological perspective, or to be useful. Physically the psychoactive constituents are not dangerous, however other poisons contained in varieties like the Aminitas and non-psychedelic look alikes do pose risk of serious harm and even death.

What tha fuck is going on here? Came from Russian imageboard here to checkout if /sci/ is better on 4ch. So all what I see are people showing off their collage grades, how-to-start-learning-maths/programming threads, what shape is better thread, "Why is biochemistry so much more interesting than pure chemistry?", IT noobs threads.
Chto za huynya blyad'? Where is fucking science?On Russian imageboard we discuss really important subjects, such as consciousness, Integrated information theory ,immortality, rocket engine and many many others. And real sciense discussions with conlcusions, while Russian science sucks big cock. Even our"stupid questions thread" does not contain so stupid and senseless posts like this board.We're tying to fuck up pseudo-science things like SETI etc. And actually this isn't just about /sci/ but about other s sections as well. What is wrong with you guys?

Cube, because it's the perfect logical representation of three dimensions, length width and height equal. Spheres are plebes- they occur naturally in celestial bodies and bubbles

but the mighty cube is the stackable achievement of man kind. Tetrahedrons are arranged creatively to form houses. 90 degree angles are the most beautiful angles since they unite the earth and sky.

I love cube

Also do you believe math will unlock the secrets of the universe that we are looking for?

So if there are infinite universes in which things are slightly different then the other..

Is theren't a universe where a blade of grass was leaning to the left, but everything was the same as ours now? Or one where it's leaning to the right and everything is the same?

At what point are these multiverses just like the Stage or Level creator of a game where you dictate it's environment based on just your imagination alone? Because after all, these are INFINITE, anything you can think of can happen, given the prior conditions of the universe in mind of course.

So are multiverses really all that exciting?

i believe this is a small part of why alot of scientist believe in a creator.
Just like we create a videogame world its inhabitants have no idea of the world outside but are able to study how things work, study the code,
our games are rather primitive since they are made from 1s and 0s and it ends there, but the game of our world well it seems to just go on and on and on and on and on and on with no end in sight
i can but wonder how deep will it go until we reach the "1s and 0s". And thats not even what you asked about.

When we talk of infinity can you really think of something in reality be infinite, are these infinite mutliverses really infinite? try to grasp this, we apply infinite in math and in reality differently.
In reality infinite is something we arent able to measure the number is too great that we dont have a number for it, hell numbers arent enough to count all of it, its that much, so the term infinite has a different meaning. In reality everything has a beginning and an end. Before there was time there could have been nothingness it ended and time began. Now the better question comes when will it stop going deeper and deeper? When will the "infinite" layers end and what comes after? Is it all just ever expanding? what can hold all of this expansion? nothingness? The same nothingness that started time a start? why? Well fuck if i know.

To answer your question, multiverses alone might not be all that exciting but when you add in the rest of the reality and go deeper and deeper adding more detail its just gonna fucking blow the mind up, and its just keeps going and going and going , i truly wish immortality would be a thing so i could have my brain fucked vertically "forever"

And yes in the mutliverse theory everything happens i think it explains that in any source you have

The multiverse theory is a failed attempt to ignore the Creator's intelligence and will. It pretty much implies heaven and hell, magic and randomness, whilst a smart Creator is a simpler and more coherent explanation for our fine tunning. Multiverse theory is Modern Paganism.

Since time is all perspective based on position and direction/speed of travel that suggests that free will is an illusion. Your future has already happened in the perspective of someone across the galaxy moving in the opposite direction.

Doesnt this also sugest that theres a mathematical equation that can predict the future as well?

According to the demarcation criterion of pseudoscience originally proposed by Lakatos, a theory is pseudoscientific if it fails to make any novel predictions of previously unknown phenomena, in contrast with scientific theories, which predict novel fact(s).[14] Progressive scientific theories are those which have their novel facts confirmed and degenerate scientific theories are those whose predictions of novel facts are refuted. As he put it:

"A given fact is explained scientifically only if a new fact is predicted with it....The idea of growth and the concept of empirical character are soldered into one." See pages 34–5 of The Methodology of Scientific Research Programmes, 1978.

Lakatos's own key examples of pseudoscience were Ptolemaic astronomy, Immanuel Velikovsky's planetary cosmogony, Freudian psychoanalysis, 20th century Soviet Marxism,[15] Lysenko's biology, Niels Bohr's Quantum Mechanics post-1924, astrology, psychiatry, sociology, neoclassical economics, and Darwin's theory.
Darwin's theory

In his 1973 LSE Scientific Method Lecture 1[16] he also claimed that "nobody to date has yet found a demarcation criterion according to which Darwin can be described as scientific".

Almost 20 years after Lakatos's 1973 challenge to the scientificity of Darwin, in her 1991 The Ant and the Peacock, LSE lecturer and ex-colleague of Lakatos, Helena Cronin, attempted to establish that Darwinian theory was empirically scientific in respect of at least being supported by evidence of likeness in the diversity of life forms in the world, explained by descent with modification. She wrote that

our usual idea of corroboration as requiring the successful prediction of novel facts...Darwinian theory was not strong on temporally novel predictions. ... however familiar the evidence and whatever role it played in the construction of the theory, it still confirms the theory.[17]
>>
>>7746286
but Darwin actually did novel predictions of previously unknown phenomena
