Existence Definition and 543 Threads

When I took a math foundations class we only did naive set theory and took as an axiom that the empty set is a member of every set. The book had formal set theory and thus listed the ZFC axioms. One of them was that the empty set exists and that it was a member of every set. I've looked at a...

It is true in Relativity that is it impossible to enihilate matter or energy to the extent that it would not come back again in some other form of information. Where did Life on Earth come from? It is also true to relativity that there is always cause to an action. (Action/Reaction) The...

How does physics allow for the existence of observers?

Alright, if any of you have seen The Matrix, then you have heard Morpheous's question to Neo concerning reality. In the matrix, Neo and Morpheous see a red chair and a television. Neo says that none of it is real, based on the logic that it is all of a computer program. Morpheous responds by...

Is this true?? I was explaining the impossibility of a complete vacuum to a friend when another friend overheard us talking. He then posed a claim that relativity says that "Something can't exist unless you see it". I have a very hard time believing this has any validity since the statement...

Photons are deemed to have their own anti-matter mirror particles (they ARE their own anti-mirror particles), does this mean that single photons do not exist? or is it that the E-M part of a photon is really the 'other' photon? Are there such a thing as Double Photon-Wavefunctions?

Mankind is irrational. Their political decisions are often not made uppon logic and science. I have critisized mankind for this. And each time I've done so, people say that I am stupid, an idiot or something like that. That have raised the question: Do mankind deserves its existence...

Are there any photographic proof of the atoms, electrons, protons and all these particles? Or do we simply see the effects of these so called particles and conclude from that evidence that there must be some sort of particles?

Nothing can be proven to exist Truth, Us, Universe, etc ... :cry: So ... is existence an idea cooked up by sum1? :-p Whether existence can be proven or not - does it matter? :zzz:

evidence against existence of dark matter?? Hi have there been any recent publications that u guyz may have read that are against the idea of dark matter and have other theories on wot keeps galaxies in orbit.? I really need ure help coz its for an essay that i have been working on. cheers.

ie. plants that get you high. Why is it they evolved? What is the purpose of these plants that induce such states? Or is it just something "that happened"? I read that Terance McKenna (strong supporter of psychedelic drug use, philosopher, etc.) believed that mushrooms in specific is what...

So, the Earth is not the http://www.dionysus.org/forums/showthread.php?t=61 huh? How so? If the Universe is endless, then we must be in its center. In fact we always will be. Why? Because that's what existence is all about, being in the center of who we are ... If you told the bug under the...

Pre-amble: This post is in no way original or even discussing an original topic if anything it is merely stating the obvious and no doubt has been discussed at this forum umpteen times.....so... Having visited and read at many internet forums and real location discussion groups I have noticed...

Dear Readers, I am Dr. Raj Baldev, Cosmo Theorist, author of Two Big Bangs created the Universe (Formed in Eternal Space), a new hypothesis, which I wrote being inspired by Stephen Hawking's appeal given in his book "A Brief History of Time", reproduced below: "However, if we discover a...

If someone is dead, do they still exist?

http://arxiv.org/PS_cache/hep-ph/pdf/0306/0306024.pdf Cold dark matter may be made of superweakly-interacting massive particles, superWIMPs, that naturally inherit the desired relic density from late decays of metastable WIMPs. Well-motivated examples are weak-scale gravitinos in...

http://physicsweb.org/article/news/8/2/4 6 February 2004 Many astronomers believe that the universe is dominated by cold 'dark matter' and 'dark energy' - a view that has been confirmed by recent measurements on the cosmic background radiation. Now, however, a group of astrophysicists in...

Have you ever considered that absolutely nothing actually exists? It existed before time started, along with absolutely everything. The awareness of this basic paradoxical duality, (Absolutely Everything & Absolutely Nothing coexisting simultaneously, together, intricately intertwined), caused...

holographic universe and our very existence in general... One night i was in a strange mood and wrote this... i don't really remember writing most of it... but i thought i would share with the community here and i am definately searching for any feedback on my ideas that anyone might have! I...

Disclaimer I: The human mind is not well suited for perceiving such complete and utter perfection. Upon viewing this video, you may collapse in tears of dumbstruck awe and terrible joy. You may hyperventilate from the shock and never fully recover. You may even spontaneously combust...

How do we know that we are alive right now? or for that matter are we dead? , we call this life but is it a illusion ? i mean am i typing this right now onto a PC or am i thinking about typing this and some of you are seeing this in your minds eye? to many question not enough answers.

i remember a referance to, binary pairs in the kuiper belt, i can not remember if a mass for the objects was given or orbital distance, my memory may be fading or wrong, can someone comfirm or dispute the existence of these objects?

There is a quote in particular I would like to share with you. It is from a 2001 Linklater film: Waking Life. 1. The quest is obviously your willingness to live your life and you want to be freed from the negatives that sporadically arise in your existence. Ok he starts off good. In life...

This is an interpretation of Christopher Langan's CTMU, www.ctmu.org , and Saint Anslem's ontological argument. 1.] If it is possible for a mind to perfectly understand[model] every aspect and detail of reality, then the mind that perfectly models reality is a super-intelligence, for all...

How many times you have read fiction strories which talks of two different worlds in different dimensions in the universe? But wait a minute, they arent different in all sense but in the time dimension. Everything is the same, but time. I have read hundreds of such stories and even a handful...

since matter and energy always behave the same way so all of our actions could be calculated if having not a soul the option of free will would necesary imply the existence of a soul or other else wouldn't exist a soul but how do you know you have free will?

it seems that the existence of black holes is taken for granted thees days, but there are people who question there existence, under the heading "binary star", in this forum, john shoemaker proposed a theory that would disprove black holes. this has me thinking "what is the evidence for...

This discussion originally arose in the thread "The answer to the 'Does God exist' question from Human Practice." I'm posting it in a new thread because by now it's a pretty deep tangent to the original thread and it's also an issue worth discussing in its own right. I am not arguing for...

Disproof of the existence of a Being that is BOTH a Necessary AND a Consciouss Being Introduction We happen to know there is a world in which we live. We have sensuoury perceptions and awarenesses about there being a world. We can be conscious about the things that exist in the world, and...

In 1935 Yukawa predicted the existence of the pi-meson. In which year was it finally discovered?

Quote from Rovelli's book, page 19: "In classical general relativity...there is no preferred time variable...[but] we nevertheless have a notion of spacetime for each given solution. [By contrast] in quantum theory there are no trajectories. Thus, THERE IS NO PHYSICAL SPACETIME IN QUANTUM...

You don't need to solve this, just tell me what problem it is... although if you do solve it you'll be a million dollars richer. Prove the existence of smooth solutions to a certain model of incompressible fluid dynamics. This is the ... problem?

is it a worthy cause to pursue the fundamentals of our existence? i am an atheist but when the final results of a long search are realised it comes down to two posibilities, we don't know ,or god created everything full stop, so that leaves me two options become religeous or stay ignorant, or...

It seems that in philosophy existence has 2 meanings. It can be taken to be an entity itself (the universe, God, etc.) or the proper definition of "the act of existing". But looking at statements made by philosophers (asking what can exist, and what does exist) seems to indicate that existence...

Existence Any form "exists" if it has been created/assembled/ or if it is a part of something else that "exists." I exist because something that does not exist cannot question itself (separate logic from above).

Although any discussion concerning this three-letter word, should be placed in the designated sub-topic of this Philosophy forum, the debate on this forum shows a large amount of post that are in concern of this aformentioned three-letter word. So the topic of this thread then is a debate...

The Center of Existence speaks of the nature of essence, which is our origin. What does this entail? First off we start with our general outer appearance or "form." This is where our material "physical" being terminates and meets the world. By which other beings like ourselves are able to...

Follow your spleen, not your mind. Only that can lead to enlightenment. When you open yourself to the wisdom of your spleen, you discove the miracle of the true nature of existence, and can fulfill your divine purpose.

This argument 'evolved' from another thread of mine. I think it's an excellent argument to show that 'God' exists... How do you know that anything exists? Your whole understanding of existence is gleaned from five senses: sight; touch; taste; smell; hearing. To that, I would add that we have...

In several threads the subject of existence arises. What do we define as 'existence' and what kind of existence can we recognize? First and foremost we should recognize that existence in the real sense (something that exists outside of our mind, has existence on it's own) is material...

Existence is elusive and tantilizing for round headed carbon lumps. The textrium of existence centers around the shininess of this elusive covering. Existence is a textrium and it is not a textrium all at the same time. The proof of this can be found in the hyfig joppe shole. This is all...

The Paradox of Existence Existence is demonstrably paradoxical, that is, it does not make rational sense. Nature makes abundant sense but existence itself is patently irrational and, thus, possibly supernatural. So profound is this paradox that it may be forever beyond our ability to...
