instantaneous doesn't exist

[dream431ca]

Another physics/math thread.

Here is why I think instantaneous doesn't exist:

Everything in the universe has to happen within a certain time. Instantaneous means that something happens without rate of change (or time), Therefore, if it takes absolutly no time to do something, it doesn't exist because it doesn't change. Instantaneous is just a excuse humans make for something that changes so fast, they can't measure it. Infinity is the same way. Humans have infinity an excuse for something so large they can't measure it. There, i've said my share. I just like things that go beyond the human mind. Discuss......

 

[Ennui]

not much to discuss since I agree

I think that's generally assumed that instantaneous doesn't mean it takes 0 time, it just changes right away, as in a very short time..

Infinity means never ending. There are an infinite amount of numbers, which is common sense.

No...the real definiton of instantenous is something changes with out time...so it can't exist.

Infinity also means that something goes on forever...which we can't measure...so there will never be an infinity about of numbers because humans will stop at a certain number and not go any higher because there will be no point.

Weeeell... duh...

I think time is just a horrible illusion existing in our minds, because we can't percept it as it is... It's a good concept to think of the future and the past as we see it, though.

I've gone into those theories and my brian hurts

.Yeah.

instantanious is a zero interval within a large interval.

when you acelerate a car, your speed is building up .. every instantanious moment has its own speed.
just like when you walk .. you keep changing position, so every moment you are in a certain position.
Think of it as a point in a line. (btw, a point has zero dimensions)


We can only measure what happens in an instantanious moment when we know what happened before it and what will happen after it. That's where caculus starts (it doesn't stop there though).

People aren't using it in that definition then, I would hope most people when they say "press the button and the light instantly turns on" know that it's however .5 microseconds or however long. It's used in common speech as exceptionally fast.

There are an infinite amount of numbers because we can think ahead. You know there are. It's not debatable. Any debate against it goes against common sense.

this is an example of wiseass scientists getting on our case about colloquialisms

I'll colloquialise you, churchy. Now get in the soapbox, and stop eye bleeding in my rhubarb sundae.

Not true. How do you explain your cognitive abilities?

You were born -- why is it in a supposed galaxy of infinites existing of time, of which, a full past history went by without you, is it then on your birthday, did you exist? You dont recall a building up point for yourself -- because it was not capable. However, you just became conscious.

That seems like an instant, or beginning.

Instantaneous does exist, however, it is an incorrect term to be applied for most subject discussion.

What are we applying reason to, were an instant might or might not exist?

Instantaneous means that something happens without rate of change (or time), Therefore, if it takes absolutly no time to do something, it doesn't exist because it doesn't change.

Somethings do not require change to exist. If something does not exist, how can you change it?

If you apply change in the sense of, it did not exist before, but it does now -- were the sect of math changed because of a new existance, we could use instanteous to describe its arrival -- not work out mathematics with a human expression without a mathematical character of reasoning.

Instantaneous is just a excuse humans make for something that changes so fast, they can't measure it.

So, if you cant measure it, it does not exist.

Fine. Measure space.

Does space, exist?

Infinity is the same way. Humans have infinity an excuse for something so large they can't measure it.

Can you measure infinites?

Interestingly, if someone were to try and measure a smaller amount of time than has been measure...they would apparently create a black hole.

(Well...sort of)

My own pet theroy is called the loop theroy
Scientists think that eventually evrytihing will fall back in on itself and then there will be a big bang and it will all happend again. Obviously next time it will be different.
But engergy cant be destoryed, neither cam atoms or parts of atoms.
So this will go on forever.
So everytime it will be a bit different, as in for infinity
Infinity = all possibility because if something goes on forever every single way of it happening will occur
However it isnt infity because there is a finite amount of the ways something can happen, though on the scale of the unvierse this is a unmginably huge number.
So sometime in the future, way way in the future there will be big bang WHERE WHAT IS HAPPENING NOW WILL HAPPEN AGAIN
What is happening now has happend before
But if the two points are the same, how do we know which is now and which is the future? We dont so they may as well be the same time, therefore the whole of existance is going round in a loop.

I think you all are philosophising (.. a word? :d) things that really are common sense and stuff.

But I've never been one for philosophy myself. Hehe.

Instantaneous in my mind is indeed true. It an occurance that is completed without perceptible delay. There are many things that the human mind has a hard time percieving, but that doesn't mean that they don't exist. To me, instantaneous means the very second something happens. You don't bypass time doing it... its just that by the time it has happened, its already over in the split fraction of a second that it occured.

I'm no good at discussing these things scientifically, but the idea that instantaneous doesn't exist is kind of silly to me =P
