A$$Bandit,
You're in a math forum. What do you expect the people to be like? Of course we're all going to be here debating the existence of numbers, time, etc on Christmas Eve.:D
Does anyone think that 0 is a way of naming something that exists in our subconceinse (argh spelling)? Its probly a dumb thought, but it might go somewhere intresting...
noQuote:

that is something someone would say after smoking a big doobyQuote:

you have something against doobies?
lol far from it... but it sounded like something i would say after smoking one :DQuote:

Doobies are the essence of philosophy, btw. :)
all your doobies are belong to ME
BTW..
if you want some heavy thought on time travel... check this link
http://www.physicsforums.com/topic.a...&TOPIC_ID=8280
Theory of time travel is rubbish talk (ie theory).
i tend to think it is impossible... at least traveling into the past anyways.. i won't say passing into the future isn't possible..
back when they thought the earth was the center of the universe... if you called that idea rubbish.. they would have killed you for treason...
so how can you say it is impossible... it is impossible at the moment.. but possibly not someday...
who thought we would put a guy on the moon? or even go into space for that matter....
technology is expanding exponentially which allows it to develop much more rapidly than it once did...
check out this article if you have a good understanding of physics/quantum theory.. or even if you don't...
http://freespace.virgin.net/steve.preston/Time.html
i agree...lots of stuff could be possible one day. it's actually all possible right now, we just don't have the brain capacity and resources to figure it all out.
true. but don't expect things to happen overnight. you are likely to hear of the new technology years before its finish thx to the internet
Well if they do ever learn to travel into the past, it will be possible at the moment.Quote:

Oh, and don't forget, if they travel into the past, there's another dimension that'll be following that person's moves.. if you understand what I mean.
I personnaly think that time = x / gravity (+ or * or ^... or..) speed and whatever else we havent found..
and unless that hits infinity... you'll never get to 0 (time stop.. before reversing..)
Hey, and if you went back through time, would it be instant, or would you smack into yourself .000000001 seconds ago?!?!
Well, since this has become an entirely philosophical discussion, here are my thoughts on time travel, time warp, the future, etc:
I don't know about traveling to it, but it is certainly possible to change the future. Say either "A" or "B" out loud. Whatever letter you chose changed everything that is going to happen in the future. If you had chosen the other letter, your life would be entirely different. So maybe there is a certain sequence of actions which will cause any given sequence of events to happen in the future.
theoretically...that's right, but would it really change your whole life? i personally dont think so. it just doesn't make sense.Quote:

Wrong, because if you were presented with the same situation again, with all the variables the same, you would pick the SAME letter. We think we make choices in life, but there really is a "fate", which, if we had all the variables, we could predict with enough accuracy... even though the outcome would change the outcome ;)
But, if we were able to travel back in time and change a choice.. then we would have to make sure we told ourselves to travel back at such and such time so as to stop some sort of weird double reality.. and even if we did manage to make the change, it was "fated" anyways! You wouldv'e done the same thing if lalalallala
other things maybe possible, but time travel isn't. lets talk about something more interesting: they cloned the first baby human
http://story.news.yahoo.com/news?tmp...man_cloning_12
http://www.newscientist.com/news/news.jsp?id=ns99993217
tell me what you guys make of it
LOL AHAHHA OMG OMG... That really makes the cloning story more believable :D .Quote:
Vorilhon and his followers claim aliens visiting him in the 1970s revealed they had created all life on Earth through genetic engineering.
And bugz, we ARE travelling through time RIGHT NOW, at a different speed then the people further/closer to the center of gravity.:p
I personnaly do think you can't travel into the past, only VERY SLOWLY into the future (rotate at 99999999999999 kmh around a black hole anyone?)
Now if we learned to control gravity to some extent.. we could literally "slow down" the enemy, or speed us up (scientific purposes as well as military).
Or maybe gravity has nothing to do with it at all and it's some other power changing astronaut's speed compared to ours.
non-sense! time doesn't have anything to do with gravity. the synchronized clocks goto space and come back with different times is because the mechanical parts were affected by gravity, not TIME ITSELF!
Even the digital ones (they brought non-digital??)? And what about the astronauts being a few seconds older??
You have as little proof as I do right now ;).
actually the faster you travel, the less time actually does pass. this is proven. as an object approaches the speed of light, the object travels through the 4th dimension(time) less than it would have had it been travelling more slowly. I can't really explain it... unless I can rustle up another dooby...
I wonder if the upll of gravity counts as speed even if your against something else solid?
As in.. every second you are going SLIGHTLY down and SLIGHTLY up.. and it would slow down your passage of time.
And maybe we are looking at everything the wrong way.
Maybe there are 4 dimentions, the directions, and "speed", which allows us to move through them.. and if we go too fast.. we actually.. slow .. down.. hmmm.
true, in fact on my part i have no proof at all, its just all speculation. but how does one ever know if someone is a few seconds older or not? I'd like to see one of these studies! you see from my POV, all physical matters is affected by gravity, even light (by black hole). so thats why the watch is off, because it is affected by the difference in gravity somehow (digital or not). but time... i don't think its a 4th dimension so therefore to me there is no time travel and won't be ever. time to me is just a measurement of how long ago it was (or how long in the future)Quote:

Time exists within this same dimension. Time is not the 4th dimension.
It's a simple notion.
Watches are mechanical, time does not tell them to go. Time isn't pushing the hands. A motor powered by a battery is.
And, if time is increased or decreased, as is supposed? When is the inversion of that to adjust back to the time everyone else is in?
Otherwise, how would you know you traveled in time, as you 'should' be compliant with other people of that time.
Time travel is a ridiculous idea.
Let's say we place you inside a space capsule, and send your spaceship hurtling off into space at, say, 0.98c (98% speed of light). While you are travelling out there in space at such high speeds, time will slow down for you. A few minutes will pass for you, but it will be a couple thousand years for us. So if you were to (heaven forbid :p ) return back to earth at that speed, you will now be in the future.Quote:

Simple as that.
Now the practical imlementation of this... well... heheh :p

No, you can't.
If zero doesn't exist, I propose that we invent it, to allow the following question to be solvable:
A = 3
B = 3
C = A - B
What is C?
Also, if zero didn't exist, Then the only numbers convertable to binary would all be of the form 2n - 1,
And I hardly think computers would appreciate half of its numerical system being nonexistant!
:)
Also, if Zero didn't exist, how would anybody remember this guy's name?
http://www.vbforums.com/attachment.p...postid=1312599
Furthur, What would we call the central location of a nuclear blast?
And, if Zero didn't exist, then We'd never have had all those great movies and shows about that Masked Mexican Sword bearing hero!
;)
we invented zero wayy before we use algebra and computers (binary).Quote:

siyan,
That makes all the more sense, because infinity is undefined! Want to prove me wrong? Ok, what's the definition of infinity?
http://mathworld.wolfram.com/Infinity.html
Infinity isn't undefined really. It simply cannot be represented in the real number system.

My point is that there is as much basis for claiming zero doesn't exist as there are for all of the whole numbers (and many other things besides).Quote:
"These are labels, categories, ideas and concepts that have no physical existance. Or, more precisely, there is no physical object that is the sum of the whole concept. The concept is always (infinitely) greater than the physical instance."
your point being???
Simon
what is the point in saying that something exists?
Kedaman
To claim that something exists is to claim that some entity is objectively observable. It's existance can be intersubjectively tested.Quote:
what is the point in saying that something exists?
For instance, if I saw an image of a car in my mind, I would not claim that it actually existed because it would not be objectively observable (only I could see it).
To claim that something exists is to establish that it can be experienced by anyone who cares to experience it.
I don't need to. If you were more in touch with science news, you'd know that it's already proven. Here's a good place to start for you: http://sciencenews.orgQuote:
