Yep.

Like I said, a tree might not make a sound. There has to observation.
EzDay281:

You cant use your example because the tree might not have made a sound in which case the birds nest didn't fall. Out of the litterally infinate possibilities of the tree making a sound, one of those possibilities might not make a sound. We wouldn't know though because no one was there to hear it.

Our presence has nothing to do with the sound being created in this scenario.

Okay, what you can do is take a bare room, and make sure no insects or such are in it.
Now, setup a camera, and have it take a picture of the inside of the room.
As you'll notice, the camera will work. Why?
There was no one in the room to percieve the light, which is required for a camera to work, so the picture should have turned out all black!
OMG HAX!

Technically, if you knew anything about quantum mecahinics, if there is no observer of an event or object it never happened/isn't there. The tree analogy is imperfect, because there are plenty of observers in a forest. (animals). If something is not observed tchnically it never happened. How do you know it happened if it wasn't observed? You don't.
Quantum mechanics has been scientifically proven to be correct, several times. Its a very wacky theory, with some odd experimantally confrimed impacts on our perception of the universe.
EzDay, the camera picture itself counts as an observation, because it's recorded information. Therefore, there were observers in your blank room, and an observation was made. QED. We, by setting up the camera, have caused observers to appear. Its not humans or life that acts as an observer, its anything that can record or store information.
Egg came first, as ihatett said.

wow...... that was a good explanation of the tree thing, and of the camera. but then that means that there are unawnserable questions out there. cus somethings noone bere whitness to. i dont know what they are.....but that means that they dont happen? i dont know......

So then...
If someone is killed in their sleep by something not alive, say a chandilier falling on them, then how do we know the chandalier fell on them? They couldn't have observed it, they were asleep. Nothing else was in the room. Yet we know that the chandalier fell on this person.

Quantum Mechanics my ass.

If a tree falls in the woods, and nothing (not nobody) is around to hear it, does it make a sound?

Yes, because, though nothing heard it, the vibrations were still caused by the tree's contact at a high velocity with the ground, which knocked the bird's nest over. The bird never heard the sound nor did anything else, yet there on the ground, not the tree, lies its nest.

Let's take another example:

Nothing, absolutely nothing, except possibly god, was around to 'observe' the creation of life. So therefore, it could never have happen.

Holy Cheeze Pie, Batman! We don't exist!!

And if you say god counts as an observer, find me some solid proof he exists.

In that case, Dr.Sh0tgun, there is an 'observer' for any physical event, because anything that is effected by something is 'storing information', in which case, my analogy isn't needed anyways.
EDIT:In Shapechanger's 'chandelier-falling' counter, the chandelier itself, along with the corpse, and the air itself, are storing the information of the fall and kill.

then how do you explain evilution..........hmmmmmm. thats a good one...

Well there isnt an observer for every event, at the microscopic scale, where quantum mechanics applies.
For example: Isolate an electron. What quantum mechanics says is that the electron has no properties until observed (and even then its properties cannot be solidly determined, only given a probability). There are no observers to attest to the fact that its has a postion and a spin and a velocity, so therefore its spin could be anything, its postion anyhting, its speed, anything.

Gezzus, I'm only in 9th grade, stop burning my damn head down. I don't even know what the hell are Quantum Mechanics geezus make some less "scientific" sh*t for us to read man -_-

Just don't read this topic then.

Ya, well this is simpler crap than things I was thinking about last year when I was in 7th grade(starting 9th in a month).
And part of the problem is, it's kind of hard to simplify it when you're already using terms and examples that are known and understood by most people that have finished the fourth grade.

So then it's just me with my stupidity

Not everything in qm is completely accepted.

What the hell is QM?

Quantum Mechanics

Hmmm, having any effect and actually occuring are two completely different things. If you're not there, it won't have any effect on you (except in very rare cases). It still occurs though. I'm sorry that I'm using common sense in this one, because technically there would be no way to prove that it happened.

Quantam Mechanics is still a theory, is it not? What about the Butterfly theory? We do not witness the butterfly flapping its wings in another dimmension, but we witness the actions in our dimmension. However, we do not know what it was that caused the actions. Wouldn't that cancel it out? If a tree falls here, forces something to happen in another dimmension, and through a chain of events causes something to happen here, wouldn't it still happen even though we never witnessed the first event?

In other words:
If a tree falls in a forest and noone is around to hear, does it make a sound?

(About falling tree) Geez, sound is merely vibrations and the vibrations that vibrate against your eardrum are vibrators... I mean what you hear... (I used vibreate in a sentence so much lol. I hope never to do that ever again)

Well, people seem to think that, just because it's one of the things that the human body percieves, it magicaly disapears when there's nothing that can hear it around.

How about this:
Take a deaf man and have him near the tree. Close enough he'll be able to feel the moving air. He's deaf, so he can't hear it, but he'll be able to tell you that the air was moving a lot more after the tree fell- and that's all that sound is, movement in an object.

if that made sence to anyone raise your hands............

i get what you mean aobut the QM, but there must always be someone, or something there to see, hear it. there cant be things out there that no-one has seen or heard.
