If I can imagine it, it is possible!

Recommended Posts

Hey guys especially moontanman I just want to apologize for some very rude and disrespectful comments I have made lately I guess I just have been very frustrated because I can't stack to anybody here on top of recent family troubles but none of those things are an excuse to be an absolute jerk

I can't imagine how it could be.

But I'm almost sure that however you imagine it to be, it's probably some other way.

Forget science based arguments. Forget philosophical arguments. Forget logical arguments.

If someone gives me the old 'Anything is possible.' spiel, I say:

OK. Stand against that wall facing parallel to it with your left foot and shoulder pressed against it.

Now lift your right foot off the ground.

Call me again when you have succeeded.

I never hear another word from them on the subject.

I succeeded on the 2nd attempt (had to adjust my balance), but I've yet to levitate.

Although I'm unsure how one can stand parallel with the wall if only one foot and shoulder is pressed against it?

I think you may have misunderstood (I can be a bit vague sometimes). By "standing facing parallel", I mean that a line taken through your body from front to rear should be parallel to the wall.

The title is a common view among crackpots.

This is a situation in which something is conceivable, but logically impossible. This means it is not the case that whatever you can imagine is possible. Crackpots, take note: the fact that you can imagine something in no way implies that it is possible. It doesn't matter how clear your perpetual motion device/unified theory/God/electric universe is, imagining it doesn't cut the mustard. This is one of the reasons you NEED the math.

Agreed:

I do though accept the scenario, that  humanity, given the time, may well achieve all that the laws of physics and GR allows.

Without a citation, I would say that many novels are based around time travel. Do you believe it can become a reality?

I take it you didn't actually read the OP. It's generally good practice to do that before posting in its thread.

The title is a common view among crackpots. They often think that the ability to imagine something means that the universe might actually be that way or could have been that way were things differently. To use philosophy words, they often think that conceivability means epistemic or metaphysical possibility. But, the question is, is that true?

 

To find that out, we need to find something that is conceivable but is impossible. For the first sense of possibility, (how things might actually be), that is incredibly easy. All we have to do is find something that is conceivable but not the case. Have you ever been wrong about something? If you have, you've shown that conceivability does not mean epistemic possibility.

 

The second one is a bit harder, since there's disagreement on the exact requirements of what makes something metaphysically possible, but we do know that for something to be metaphysically possible, it must also be logically possible. That is, were things different, an accurate description of the universe still wouldn't entail a contradiction.

 

So, we can knock this out by finding something which is conceivable, yet logically impossible. Can we imagine things which are contradictions? You might be tempted to say "No one can imagine a square circle!". But I'd like to talk about one which almost everyone intuitively conceives.

 

People intuitively like to group things. It's how we make sense of the world. We have apples, chairs, etc. All you have to do is put things together and you have a group. In mathematics, we call these kind of groupings 'sets'. The things in these groups are called "members". Any group of members of a set is called a "subset". This does mean that all sets are subsets of themselves, but that's not of interest to us here. What we're interested in is the idea that you can group whatever you want into a set. You can make sets of sets. You can take your set of cats and your set of dogs and put them together into a new set!

 

So, let's take a look at a specific set: the set of all sets which are not members of themselves. The set of all cats is not a member of the set of all cats-it's a set of cats, not of sets! So, it goes in! Likewise, any set consisting of no sets will go in this set of all sets which are not members of themselves.

 

So, we pose a question: Is this set of all sets which are not members of themselves (from here on out, we'll call it 'R') a member of itself? If R is a member of R, then it fails to meet the requirements to be in R, so it isn't a member of R. That's a contradiction, so that's no good. That means R must not be a member of itself. But what happens if R is a member of itself? If R is a member of itself, it meets the requirement to be in R. Since R is the set of ALL sets meeting this requirements, it goes in. Again we have R both being a member of itself and not being a member of itself. So, either way, weget a contradiction. This means something is logically impossible. But we got this result simply from the definitions of sets and members and from the very conceivable idea that you can group whatever you want together.

 

This is a situation in which something is conceivable, but logically impossible. This means it is not the case that whatever you can imagine is possible. Crackpots, take note: the fact that you can imagine something in no way implies that it is possible. It doesn't matter how clear your perpetual motion device/unified theory/God/electric universe is, imagining it doesn't cut the mustard. This is one of the reasons you NEED the math.

Your whole answer fails one simple truth.  You are assuming you did not just write all of this on a forum on a web server loaded in your web browser on a computer that is on your desk that you are using as a human avatar in a simulation of life.  If it is a simulation, then anything you can imagine is truly possible but only if we the admins (God) allow your imagination to be true.  Think of the prison in Minority Break.  Maybe you are a convict and I'm the guard controlling your "punishment" aka Life.. and thus I can grant you a fantasy or ruin it by adding painful aspects to it.  But if it is real life, then no what you imagine isn't possible.  So all of your work is useless and irrelevant as it is based on an assumption that "Life(TM)" is real and not a simulation or an augmeneted reality experience.  If I stuck a chip in your brain with Augmented Reality aspects, when you walk down the street and see a space ship the ship part is a 3D illusion but you believe it because you don't know the chip is in your skull.  Far fetched, until you realize whether Life is real or a sim... :)  Go see Dr. Strange from that perspective.. the doc wakes up in a hospital right?  And goes on a quest.. but he never really woke up.. The neurosurgeon crashed his car and was crippled.. then they fixed his body.. stuck a chip on him like VR/AR stuff.. and he opened his eyes in a simulated reality... and all of those dimension things are just his "game" experience.  His real body was being handled in some cripples-hospital place by nurses, drones, nanites..etc.  So in reality Dr. Strange is a paralyzed crippled man.. whose conscience is playing a simulation of life... so no sir.. Dr. Strange didn't go through many dimensions.. just different levels of "Life v35.694.3.504beta9". :)  See how the movie now has a different meaning? :)

So if you can imagine it, it may be possible. :)

Peace out. :)
