If an airplane flies over but no one has any physical evidence, did it fly over?

Question

If it were unmanned or of unknown origin, did it still fly over?

Your prof brought in a dead cat? He's probably been carrying around that cat for weeks.

Answer 1

Yes. It takes a pilot to fly an airplane. The pilot knows.

Unknown origin and unmanned, but yet you have asked the question stating an airplane flies over. If you can ask the question, then the airplane flew over.

Here's another one for you. God knows if it flew over.

Also, I can't see bacteria, but I know bacteria is there.

I have no physical evidence of gravity but it is there.

I have no physical evidence of God, but I know God is there.

Answer 2

Ah! This is different from the tree falling in the forest one, isn't it?

Yes, it did fly over, because someone had to have flown it. Even if it were unmanned, it would still have to be controlled somehow. Airplanes are inanimate things, the only way for them to move is to have something move them.

Unless the airplane was something like...those robots from Transformers (Though I thought the concept was VERY far-fetched) Yes, I think it did fly over.



Cool point, All knowing dyslexic...I heard that one before...
So it was only real to the professor, but not to anyone else?

Answer 3

Isn't this kind of like the question of the tree falling in the forest?

Anywho, yes it did fly over because it is physically incapable of to not have evidence as a pilot is required to fly one.

Answer 4

the cats not dead till you see it
a professor had a dead cat in the box but didn't tell any body it was dead under the belief that because no body could see the cat and the last time any one saw it it was alive so as long as no one saw it it was nether dead or alive and it would continue to be in this state of nether life or death until some one saw it and there for forced the cat to be one or the other

Answer 5

Until I saw your avatar, you didn't exist in my world. In your world, I'm sure there are many who would attest to your existence.

To someone who knows neither of us, we don't exist in their world.

Physical evidence may exist even if one or more does not have it.

Answer 6

did you ever do something just amazing - like shooting a hole in one or bowling a perfect game - and no one else was around to witness it - still happened.

Answer 7

yes
