Time Travel

[Annah]

9/9 = 0.(9) = 1

 Wrong

 And 2/3 it seems is a finite number. Take some calculators and make it
 You can try even with the basic Windows one

 * EDIT *
 

I\'ve already mentioned that these numbers cannot be properly calculated on calculators, because of their infinity, so their answer of 0.(9) is wrong.

 Now I noticed ...
 So, you say that if a calculator, let\'s say it will be able to do operations even with that \"infinity\" of the numbers, 0.(9) will suddenly turn to 1?
wooow  :rolleyes: lol ^^
 Man, the number IS correct, but it doesn\'t have enough display to show all your .xxxxxxxxxxxxxxxx...

did you by any chance noticed that your calculator has finite space to display numbers so it can\'t display infinite numbers (rounding it up instead)?

Annah! answer where you got 0.(9) from already

- Swords

[Annah]

err yea, it\'s approximated. My bad
 And as for that 0.(9) - I approx. as well. Otherwise, the operation cannot take place.
 Even so, there is no one

Sorry, mathematics in english are not my cup of tea (although they are in french as i got 20+ hours per week - yeah it\'s crazy)

The decimal representation of a number is defined by

n = sum-k (ak * 10^-k) where ak is the k-digit.

This representation is not unique. An algorithm based on euclidian division by 10 gives a representation which is named \"propre\" in french (proper?) and is the representation we are most used with. Example: 1.

But there may be other representation called \"impropre\" (improper?).

for example sum-k (9 * 10^-k) = 9 * 1 / ( 1 - 1/10) (limit of a geometric sum)
so 9.9999... = sum-k (9 * 10^-k) = 10

Stop with the math stop with the math! *twitches*
Eh hee hee, math math math math math WHooo math! *runs oaway while taring his cloths off*

Well i dont like to read the whole thread so i give my two trias about it:

Well time probably doesnt exist in physics, but it does in biology and chemistry. think of nuclear collapse. Or the growing of organism.

Well I have heard of some experiments where they put sucha atomic clock thing into an aero plane and one  on the ground.  then they after the aeroplane landed the clock which was stationary (well I know that the earth cycles but the aero plane gets its speed added to this one), were before the other one.

If this is right we DO make time travels, the one who keeps on the ground travels into future from the point of the one in the plane and the one in the plane into the past from the point of the  one who is on the ground. Think of the clocks.

You just don\'t get it, do you?

You CAN calculate things using 0.(6) and 0.(3)

0.(9) is one.
Let\'s do that again.
TELL me the error in the following logic:
9*0.(9) = 10*0.(9) - 1*0.(9) = 9.(9) - 0.(9) = 9
So, 9*0.(9) = 9
1*0.(9) = 1

That\'s just the way it is.
You know it\'s right, but you won\'t agree to it.
That\'s called \'refusing to accept reality\'.

[elscouta]

Well, even if the result is correct, i think Arzosah miss the real benchmark of the demonstration:

The question is not what 0.(9) is. It is if 0.(9) (the limit of sum-k (9 * 10^-k)) exists. Proof of its existence are:
- any geometric sum with step lower than 1 exists (here the step is 0.1)
- it is the sum of the two 0.(3) and 0.(6) sums (the sum of two infinite sums exists and is the sum of the limits)
- noticing that the partial sums can be written as 1 - 10^-n  

Note: i hope at least one people will understand this post :/

[Kwip]

Soooo, I am guessing that you all are trying to prove or disprove time travel by arguing whether one is one???

*Kwip trys to time travel by typing . then a bunch of nines, and he secedes, for the time is now 20:43 while when he started it was 20:40!!!*

0.(3) + 0.(6) logically must be equal to 1 no matter what your philosopher tells you. I\'ve already mentioned that these numbers cannot be properly calculated on calculators, because of their infinity, so their answer of 0.(9) is wrong.


There is no insanity to math. Move on. Nothing else to see here.

well yeah using calculators i guess.. but ONLY on calculators (which are wacky anyway) is that an instece where \".9\" would equal one... outside of the box .9 is different from 1.00 and .98

also yeah what the hell does the meaning of the number one when dealing with thirds on only a CALCULATOR have to do traversing time? O.o

[rumblebelly]

well i\'m not mathamatic\'s wiz frankly i don\'t understand any of it lol. but on the subject of time travel what i think is a logical theory. it is imposible to travel forward into your time because once you leave and go forward time for lack of a better word has recorded you as gone. so it would not be your future that you see because you have changed the future by leaving your present. and if you were able to come back to where you left the future would either change again or go back to the way it was when you first left. one example of this is what if you were to have a child after you went time traveling the future you would see is one without that child because you left before you had it then that child would not have children and so on and so on. thus your future would have changed drasticly. and that\'s my two cent\'s for what it\'s worth  

[davo]

ok ok.

time in not a physical thing and can not interact with physical things.  it is a measurement just like a centermetre or kilogram.

*trying to not sound biased*...now seriously sit here an think weather or not you are really going to do this by writing down little numbers and doing maths and whatever \"1 is 1\" ect. Its not going to leap to life and take you into the future.

cheers

Foresteer, I think you misunderstood ;-)
We\'re not talking about 0.99.
We\'re talking about 0.99... (aka: 0.999999999999999999999999999999999999999999999999999999999999...99999 - the 9-s go on forever)

And I dunno how we got to this.
I think somebody tried to prove mathematics was often wrong, by stating that 0.99... doesn\'t equal 1.

[Foresteer]

oh.. well in that case i guess 9.999 in that case would equal 1 i still fail to get the relevance to time travel but hayy anyway..

\"Hey guys look! i found something REALLY awsome! Its the threads topic! i think we should go to it right away \"

except... i have nothing else to say on time travel really :/ didn\'t we just totaly hash out the issue? until somebody reads something new or has another question i am pretty sure i have expelled all my knowledge on the topic
