Yeah I remember my mate who is an Ent complaining about the time he fell over in the forest aparently he was shouting for my help for ages but I was not around to hear it. Anyway being an Ent I only just knew about it yesterday after he said hi to me about 15 years ago.

So, if it was falling in a perfect vacuum? That would rip the tree apart before it could do any falling. Mind you, even in space there's no perfect vacuum. So since the tree can't be in a perfect vacuum, not in one piece anyway, there will always be atoms to vibrate around it, creating sound. And I don't give a damn if anybody is around to hear it.

The tree would not explode... or as you put it rip apart. It would just eventually freeze... depending on the distance from the sun and if it gets direct sunlight.

I'm not convinced.
A vacuum sucks in matter, right? And the tree is full of matter. So if the tree is surrounded by a vacuum on all sides, it gets sucked to all sides. it can't decide where to go and rips apart. Assuming of course the forces sucking the tree apart are greater than the forces holding it together. But with a perfect vacuum (aka no matter) that shouldn't be a concern.
It's the opposite of things getting squished by water pressure deep in the ocean.
Things get ripped apart by the lack of pressure around them. My whole understanding of the universe points to that one conclusion.

No. The vacuum doesn't actually suck on anything. It just doesn't apply any pressure. Since outer space already applies very, very little pressure, there wouldn't be much difference in pressure between a perfect vacuum and a near-perfect vacuum.

This is correct, the only way something explodes is if the internal pressure minus the external pressure is greater than the structural strength of said object (like some deep-sea fish), and a tree has a way to equalize the pressure (that's why trees don't explode when they freeze or burn, you only hear light popping)

All choices are made in fear,
What you fear more is the only difference.
Positive decisions are made in fear negative consequences,
Negitive decisions are made in fear of positive decisions not giving the outcome you want.
Embarrassment is the fear of people knowing your real thoughts.
Greed is the fear of having too little.

A vacuum can only cause something to explode if there are secured spaces containing any type of gas within the object or body; the lack of pressure on the exterior allows the gas to expand until it exceeds the force de résistance of the exterior wall's material and causes an explosion.
Deep-sea fish will have their swim bladder popping out of their mouth when pulled to the surface too quickly, since the pressure in deep sea is much higher than closer to the surface. If humans dove to great depths without proper preparations, our skulls would implode because of the immense pressure, since the air in the cavities would become very dense and would no longer be able to provide counter pressure to pressure the water puts on the exterior of the body.
Back to the tree, trees don't have secured spaces containing gas, so they can't explode or implode.

On the philosophical note, just because no one's around to hear the sound doesn't mean it doesn't exist. Since no one was around to see the tree fall and comfirm that there was no sound, you cannot exclude that there was indeed no sound. But since there was no one around, it could also not be confirmed that it did make a sound. It's kind of like Schrödinger's Cat, unless you were there when the tree fell, the sound is both existent and non-existent; just like the cat in the box can be thought of as both dead and alive until you open the box.

the tree would explode because it contains water
the water inside it boils until it freezes..i think..
edit:vacuum doesnt "suck in" matter..unless you're talking about black holes

Yes, it would make sound.
Just because someone isn't around to see it or hear it, it doesn't mean it's not happening.
Isn't the earth itself a good example of that?

The vascular pressure containing the sap (blood of trees) and cellular fluid would make the boiling temperature above that of the surrounding space.

thanks ALOT for the link
i remember reading before that boiling point of water is directly above its freezing point in vacuum so anything with water in it explodes
but i wasnt sure if this applies to livingthings too

It means is that the planet is here. We know how planets form and how long it takes, so we know that the planet was here for over a billion years before humans were around. The earth didn't just pop into existence as it is.

Bad argument.

The tree falls, that's a fact (it's the basis for the statement). The question is, does it make a sound?
It depends on your definition of sound, if you define sound by that what you hear, then no.. It doesn't make a sound if there is no observer to hear it (animal or human).
If you define sound by vibration in the air, then yes it does make a sound.

Same with light or pretty much anything else.

Sound and light are basically both just vibrations, it's your interpretation of those vibrations that make in sound or light.

Sound happens, the same way that the tree falling over happens. It's not open to interpretation.

Not a philosophical question at all. Physics will say that sound energy is converted from the potential energy of the fall.
