Is a second infinite?

Ok just bare with me for a second...

between 0 and 1 are an infinite amount of numbers (1.1,1.00000001,1.0000000000000000000001), so how exactly does a count down reach zero?

How can something subtract from infinity?

I might be able to explain it a bit better if you like.

 

Good question, I'll be checking back here to read some stuff.
No doubt Shredderbeam will show up

And, yes, his name is Shredderbeam, not Cheddarbeam

 

Infinitely close is the same as exact. Well, some mathematicians would disagree... but limits in Calculus found a lot of what we depend on.

I could see why you are confused, it really doesn't make sense in some ways.Time is one of the few fundamental assumptions within physics. Not fully understood, but ALWAYS progressing.

 

The paradox of time and movement..

divide by zero.

 

Time actually doesn't exist. In my opinion at the very least. Time is actually something created to keep track of tasks in the ancient times. The earliest civilization that I have been able to find that actually kept track of time were the Ancient Sumerians. The creation of time began with capturing the movement of the sun and the moon and then recording their position in the sky. Which gave Sumerians a way to tell whether or not day-light or night-time would end or begin. That's the way I see it. Feel free to stab at me with your virtual knifes. I will be on the other-side of my monitor waiting to receive them.

 

No,

just because the way WE measure time is relative, it doesn't mean the progression of physical time is nonexistent. Time is no illusion.

 

5, 4, 3, 2, 1, 0. thats how.

Your logic means how do you count up to 1? how do you count to any number? Yes theres an infinte amount of "numbers" between 0 and 1, and between 1 and 2, tho that doesnt stop 1 - 1 from equaling 0

Think about this one:

Would you say that 9.9 repeater equals 10? You have been taught that a third of 10 is exactly 3.3 repeater right? tho if we times 3.3 repeater by 3 we get 9.9 repeater, does that make 9.9 repeater actually = 10?

 

You are probably right I have never put much thought into it. Maybe I will and get back to this thread.

 

This sort of time is abstract. It does not exist in reality - it is just a reference point.

 

What do you mean it does not exist in reality, Shedder? If someone had a really precise stop watch , say in the future , who's to say he can't stop the watch at 0.00001284

 

You are thinking too hard.
1,2,3,4,5,etc... are all integers. By subtracting 1 from 2 we get... 1.
Simple as that.
Unless you subtract .999999999... continuously then the answer would be 1.11111111... continuously
In mathematical notation, the answer would have a dash above it i.e. 1.111 (with dash above the .111)

You are not subtracting from infinity. You are subtracting from integers; integers are defined.

Also, there are numerous ways to find a number that is infinite or solve a infinite pattern using Pre-Calculus. An example would be the sum of an Infinite Geometric series formula.
S∞ = a1 / (1-r ), ∞ means infinite.

 

I've wondered about things similar to this.

Like, if you move a finger from one point to another, would it be possible that somewhere in that movement, you moved as fast as the speed of light?
As for this question, I don't really know. I'm trying to think of a way to put my opinion into words but I'm confusing myself. :|

 

Infinity is a concept that does not exist in reality. Some hypothesize about a "smallest possible time", known as the Planck Time: http://en.wikipedia.org/wiki/Planck_time

 

The thing is countdowns usually don't go through every fraction of a second. Because they may only go down to milliseconds, they skip a lot and therefore it will not be infinite. HOWEVER, if they really did split a second as far as it could go, it would be infinite.

 

Not really, no.

It's more of a reference..

 

You do realize if it was .99999999 repeated, and you subtracted it from 2, it would 1.00000000000 repeated with a 1 at the end (but seeing as it is infinite, there really is no end). In any sense, it's not 1.1111111 repeated.

The idea of infinity, as said before, is relative however. As you approach something to infinity, it essentially that number.

 

Well, I would say that when you do a countdown you only do integers, or else how would you ever reach 0 to 1?

 

Shredder, infinity is a valid concept, and it doesn't exist in reality, but it is only a theory that is impossible to prove. Such as pi. How would you determine the last digit of pi? Impossible. If it is the infinity theory, then it would be impossible to find out the last digit of pi, in which does exist, you would have to somehow manipulate the infinity theory, and change the way mathematicians think of the theory of infinity. Wrapping it up, infinity is a theory, and a symbol, predicting what would happen if you went from 1 to whatever number at the end of everything, which probably is possible, but the number is always rising, so it technically is impossible. It's amazing how I know all this in 6th grade, but I do. And know, I must say,


CONTRADICT!!!!!

EDIT: I forgot to submit my opinion on if a second is infinite. To have infinity, you need and endless supply. There is not an endless supply of milliseconds in between a second, but there is an endless amount of time.

 

good point.....
Gotta think more 'bout it aye?

 

It's just a theoretical numbers, not practical.
