if its possible how ... ( 5 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 ... ( 5 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 ... ( 5 days ago by ihateyousomuchx10)
wrong. it would be strictly controlled by the government.
Hey smart guy, they ... ( 4 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 ... ( 4 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 ... ( 4 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 ... ( 4 days ago by Nanumir)
the river of time could very well be shaped as some strange topological object
do i sound like a ... ( 4 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 ... ( 4 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 ... ( 4 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. ... ( 4 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 ... ( 4 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 ... ( 4 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: ... ( 4 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"
Yeah, right, ... ( 3 days ago by ispyonu111)
Yeah, right, controlled. Just like the nukes, GE and those alike are controlled today :-))
no matter what u ... ( 2 days 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
if you went back in ... ( 1 day ago by ManicPanic9000)
if you went back in time, how would you get back? :)
The problem is that ... ( 1 day ago by gomer1951)
The problem is that the speed of light is believed to be the highest speed at which something can travel, so it is unlikely that we will be able to travel into the past. As an object nears the speed of light, its relativistic mass increases until, at the speed of light, it becomes infinite. Accelerating an infinite mass any faster than that is impossible
Pythagorean rule L122 = (X2 - X1)2 + (Y2 - Y1)
time(1 - (U/c)2)1/2 (U=speed, c=speed of light) dilation factor
Wait. :) ( 1 day ago by CptnObvious21)
Wait. :)
Its possible to ... ( 1 day ago by kage7785)
Its possible to travel faster then the speed of light, its just impossible to accelerate matter trapped in our space-time past the speed of light. In our frame of reference yes C is constant and cannot be exceeded but there are other ways to by pass the ''acceleration'' albeit being theoretical and well beyond our current technology. Tachyons are an example of hypothetical particles that travel faster then light and do not violate causality.
Well said Kage. ( 1 day ago by gomer1951)
Well said Kage.
"if you went back ... ( 1 day ago by 666XZ)
"if you went back in time, how would you get back? :)" Hahahahaha your right since there is an infinite number of parallel universes the time traveler has to be very lucky to guest the one universe that the time traveler came from of the infinite number of paralell universe to return back XD
omg nerds..... ( 1 day ago by BornOf95)
omg nerds.....
The same way you ... ( 2 hours ago by dboch3716)
The same way you went back in the first place! How elementary! :)
