Did it happen?

Posted by: Mathgeekjoe

Let say there was an event that was so small that its effects get overwhelmed by quantum noise. Even with a complete knowledge of the present, it would be impossible to know if the event happen. In fact calculations would consider it highly unlikely that it happened. Did this event definitely happen?

  • No, the event did not definitely happen. The past doesn't exist, but the present does. If the effects of the past does not definitely prove its existence, then it did not definitely happen.

  • Yes. The event definitely happened. If you were to go back in time, you would see that it happened.

  • You said so yourself.

  • Obviously

  • Since the narrator is omniscient, I guess we can trust him.

  • Yes, countless events happen all the time that there are no witnesses to. That no one saw does not nullify the event, even if there is no evidence. It's the counter-point to "perception is reality". Simply because you did not perceive it does not make it less real, and simply because you witnessed it does not mean that it was real in the manner in which you perceived it.

You said the event happened in the description lol

This is too confusing.
Mathgeekjoe says2015-04-26T18:16:10.3456899-05:00
"You said the event happened in the description lol" But did it really happen. The past doesn't exist so if there isn't evidence in the present then it didn't happen.

Math geek-I think you and I could have a fun conversation at a bar with this one.
Mathgeekjoe says2015-04-26T18:20:32.7282948-05:00
I am under 21, plus I don't see any point of drinking alcohol.
CannedBread says2015-04-26T18:21:17.7006709-05:00
Learn to have fun.
TBR says2015-04-26T18:21:26.5626982-05:00
It happened, but there is no rational reason for me to believe that it happened. It is a conundrum of science that it insists it didn't happen yep still happen
CannedBread says2015-04-26T18:22:55.7977290-05:00
It brings up the question, if a tree falls in a forest, and no one is around to hear it, does it make a sound?
TBR says2015-04-26T18:25:11.2854660-05:00
It is incredibly cool. Looking back on the event, I have more reason to disbelieve then I do to believe.
Mathgeekjoe says2015-04-26T18:26:47.6167010-05:00
But did it actually happen? Does the existence of the event happening exist in the past? Does the past exist?

It seems to depend on what you consider to be proof.
Mathgeekjoe says2015-04-26T18:31:09.9492792-05:00
It is not a question of whether there is proof it happened, or if you would be able to know it happened. It is literally a question about whether the event happened.
CannedBread says2015-04-26T18:37:11.1410948-05:00
No one has answered my question yet.
Nac says2015-04-26T18:52:47.5743002-05:00
Mathgeek - your question implied certainty. "Did this event definitely happen" seems to imply that we can say, with complete certainty that this event happened. The negation, therefore, encompassed both certainty in the opposite, and a lack of certainty in either claim. The latter is the one which I hold, as true, philosophical knowledge seems to be impossible. If I were to answer this questions with the affirmation you proposed and the former of my two options, I would claim it did not happen, since this follows suit with the null hypothesis. Cannedbread - To answer your question, I will define sound in the following way. From google, "vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear." Again, true certainty seems impossible but, to ensure my answer is useful, I will answer this with either affirmation or negation. I will actually affirm this, since it seems to follow suit with the current theory of sound. The absence of a human will not affect the vibrations, since the only involvement of a receptor for the sound is the ability to hear it when it reaches their ear. This only means that, in the case that the vibrations reach a person's ear, it will be heard.

"It brings up the question, if a tree falls in a forest, and no one is around to hear it, does it make a sound?" I say yes. Of course the question is slightly different.
CannedBread says2015-04-26T18:54:15.9630493-05:00
Alright NNNEEERRRDDD!!!
Mathgeekjoe says2015-04-26T19:04:33.8312997-05:00
@Nac. I was actually debating with myself whether to ask did the event happen, rather than did the event definitely happen.
Mathgeekjoe says2015-04-26T19:06:39.9541716-05:00
I went to the latter because it would be impossible for it to guaranteed not to have happened. I ask the question to ask is there some hidden variable with the past which would mean the past exist.
mishapqueen says2015-04-26T21:53:59.9776882-05:00
I'm not smart enough to even comprehend this question.
Nac says2015-04-27T06:17:39.8041557-05:00
Cannedbread - Aw, thank you. Very few people are nice enough to call me that. Mathgeek - Fair enough. The cases in which a negative can be proven are scarce. Was my answer sufficient?
Diqiucun_Cunmin says2015-04-27T06:22:07.8616308-05:00
My first reaction was 'what on earth is quantum noise?' and my second reaction was 'hey, that's just a fancy way of saying "If a tree falls in a forest where no-one is around to hear it..."'
TheHappyReaper says2015-04-27T06:45:45.3133504-05:00
Indeed
TBR says2015-04-27T12:22:52.7412888-05:00
It is a little different than solipsism. What he is getting at is that looked at through a scientific lenses - the event can be proven to be unlikely to have occured. That is more like saying, I was there when the tree fell, I know what it sounded like, but it is easyer to prove that the tree never fell at all!
