alternate theories to explain (the absence of) time?
anyone?
I really dont have time for this...http://discovermagazine.com/2007/jun/in-no-time?
alternate theories to explain (the absence of) time? anyone? I have already posted my explanation for this.
No, wait. I am going to post my explanation for this. No, that's still not right. I am posting my explanation for this. It's all the same. As I write this, you will will read it.
As you read it, I have already written it. And yet, there it is, existing independently of both of us. >> that the fundamental description of the universe must be timeless <<
Not timeless -- time free. Until observed by someone. so if you would all just shut your freaking eyes, I would stop aging? sweet.
"The past is theory," he once wrote. "It has no existence except in the records of the present. We are participators, at the microscopic level, in making that past, as well as the present and the future." In effect, Dr. Wheeler's answer to Augustine is that we are collectively God and that we are always creating the universe.
Here's something that is very interesting about computation. It is possible to have reversible computation - zero entropy, no information lost. You can rewind the output to get the input back. This is useful for chips that don't heat up. The thing is, it turns out that what generates entropy is reading the output from the computations. It means that a little bit of heat must be generated, unavoidably. However, since you don't have to read all the output from all the intermediate computations, you can have chips that generate a lot less heat than what we currently do. You essentially have a black box.
Compare that to quantum mechanics and the collapse of a wave function. There isn't really a good understanding of exactly what happens at the moment of collapse. I strongly suspect that it's the same thing. That moment is when observation takes place, and entropy increases. That is when time advances a tick, in fact what causes time to advance. It need not be observed by "someone", xampl. Rather by something, anything. It must have an unambiguous effect on something.
Wavefunction collapse is not a sudden event, it can happen gradually.
Really? Wow. That's cool.
I thought it was a discontinuous event. I had no idea. Yeah, I'd love to hear more about the dynamics of waveforum collapse. It's a gradual event? Have people measured a partially collapsed waveform?
What is important here is to realize that whatever theory or formulas we currently use and prove to describe our world are just the best we can come up with today. They are just the perception of reality that suits us the best at some time.
We should not be surprised if future theories add or remove parts of the equation in order to describe the things we couldn't grasp before. well do you think future equations will have a t in them?
do you not think it odd if they dont? what if there is no t? no t, anywhere. loneliness. utter, unabashedly brzen loneliness. at least all those stories of immortal and infinite soul would be true. |
