Because messing ... ( 4 days ago by TheRedDragon2007)
Because messing around with time is a very bad idea, cause and effect, anything you do in the past affects the future.
go back to the past ... ( 3 days ago by ghettobeats)
go back to the past and bitch slap Eve really good before she eats that apple.
I don't think it's ... ( 3 days ago by ispyonu111)
I don't think it's possible to travel in/across or within time. Time is not a physical object of any kind. Time is a concept or a mental construct created by an intellect to be able to analyse physical events. However, the entertainment value of the concept of travelling in time is great. That's why we love to speculate about it.
A common misconcept ... ( 3 days ago by ispyonu111)
A common misconcept about time is that time acts and behaves sort of like a VCR cassette and VCR player. Well you cannot FF or reverse events that will happen or did already happen to the physical objects. The present is like a result of eqation or a calculation of a mathematical formula. Any manipulation of that formula will change instantly the result. So if you'd kill your mother at the time point before you were born, you'll disappear instantly from the present time.
And another concept ... ( 3 days ago by ispyonu111)
And another concept of time travel would be an eternal existence of a civilization. Let's imagine that humans mastered time travel, and in an event of some incoming cosmic calamity, they'd simply move the entire solar system back in time, say couple of millenia back, and everything would be honky dory again. In this scenario we'd skip the mental labirinth of endless paradoxes that would take place in such an exercise.
Travelling in time ... ( 3 days ago by ispyonu111)
Travelling in time would be great for making money fast'n'easy. Go back to a time point when a major jack pott at your local Lotto wasn't won by anyone, and place a bet with the winning numbers which you'd obtain from your present Lotto archive. Cool, eh? Once we'd master time travel, the life will be a piece of cake.
Not to mention ... ( 3 days ago by ispyonu111)
Not to mention really groovy things like: kill Hitler and Lenin when they were babies, and WW2 + USSR would never happen. Go back to Jurassic, 'bout 100 million years, and snach a T-Rex or Brachiosaurus egg, you'd make a fortune with a theme park based on a real dinos, no DNA cloning needed. Travelling to the future wouldn't be really necessary.
Time travel would ... ( 3 days ago by ispyonu111)
Time travel would be a hell of a thrill for a japanese physics graduate (like pictured Michio Kaku) with some patriotic flavor. Such a guy could go back to pre-WW2 Japan, and equip japanese empire with a ready for use nuclear warheads at the time when US didn't have a clue of it. Pearl Harbour and other possibilities would be quite a sight.
Time travel if it ... ( 3 days ago by ispyonu111)
Time travel if it would be possible, would be the ultimate disaster source for the entire universe, and not only for humanity. But, hey, no sweat, time travel is like a chess game. Exists only in the players mind, and is 100% virtual, meaning: unrealistic. However, this concept will be fun to elaborate on, for me and you. I call time travel: time killer. I think of time travel when I got nothing better to do as sitting on a loo for instance.
if its possible how ... ( 3 days ago by uchihaakall)
if its possible how come its never been done yeah they got all their information that sounds right but they still cant do it
so what you're ... ( 3 days ago by ihateyousomuchx10)
so what you're telling us is. that... you are fucking retarded and are too stupid to of heard the amount of energy required for it to be possible. oh ok then fuckwit. you're a dumbcunt. congratulations :)
wrong. it would be ... ( 3 days ago by ihateyousomuchx10)
wrong. it would be strictly controlled by the government.
Hey smart guy, they ... ( 2 days ago by MrStosh314)
Hey smart guy, they don't have all the information and they don't have all the technology to do it. If you listened at all to what Dr. Kaku said maybe you would know why we don't have time travel right now. He stated that you would need to harness the amount of energy from an exploding star to alter space/time. We can't even control our own environment/weather let alone the energy from an exploding star!
time is just all of ... ( 2 days ago by cheezysingle)
time is just all of the stuff in the universe doing stuff all of the time,if all the stuff in the universe stopped doing all that stuff,.then there would be no time?
don't slam the door ... ( 2 days ago by Nanumir)
don't slam the door especially if they look exotic, meaning different than the people of today, but if they look normal then you might be doing yourself a misdeed letting them in if they're some crazed psycho or something out to get you
the river of time ... ( 2 days ago by Nanumir)
the river of time could very well be shaped as some strange topological object
do i sound like a ... ( 2 days ago by uchihaakall)
do i sound like a smart guy? i never stated that i was im just saying what i think so no need to start calling names these are just their facts about time travel so take it easy man.
there is no time ... ( 2 days ago by ciilman)
there is no time machine now and it will surtenly not exist in the future why do you ask well if there was a time machine in the future they wold have traveled back in time..
to our time and there is no one traveling back to our time because it never becomes possible sorry...but that is the borring truth.
You dont understand ... ( 2 days ago by USSR1941)
You dont understand. If you have a time machine you cant go back in time to show the other people to prove it. Because in the past time the machine did not exsist. Therefore there would be no machine for your molecules to materalize into. If a time machine is created you could travel to any time in exsistance except to a time before the date when the machine was created.
Look up John Titor. ... ( 2 days ago by jaguarclaw)
Look up John Titor. I believe the case to be real. Also, black holes can punch a hole in spacetime. Just throwing out ideas here.
USSR1941: how can ... ( 2 days ago by ciilman)
USSR1941: how can you know so mutch about a machine that does not exist? i mean ho says that when you`"travel" with a time machine that you have to apear in a simular one in another time that proves just how impossible it is to travel from one time to another to a exakt possition this is just something you're imagining like marvel imagined and made up all the superheroes
End of discussion ... ( 2 days ago by ih8theismyo)
End of discussion right here...FIRST, time does not exist we pass time does not. It was something we created because our simple minds couldn't grasp the way the universe moves and the way we pass(grow,live and die etc.) So it is impossible to "travel through time". However, I will pose a question. "Do you think it is possible to travel through the multi-verse, in other words to parallel universe?" Reference book: "The Fabric of Reality: Parallel Universes and it's Implications"
book written by: ... ( 2 days ago by ih8theismyo)
book written by: David Elieser Deutsch, Physics professor at Oxford....and a great read! Reference book: "The Fabric of Reality: Parallel Universes and it's Implications"
no matter what u ... ( 7 hours ago by swordofwind)
no matter what u cant go to the past before the machine was created. u wouldnt be able to prevent yourself from being born like the movie time machine he couldnt save the girl because the girl was the reason the machine was created if she lived the machine wouldnt be there thus making it impossible for her to live
