make a time machine?

Question

how do u make a time machine

Answer 1

The current consensus is that traveling backwards in time is impossible. You can move at a faster rate into the future by traveling at a speed approaching the speed of light. When you return to the frame of reference of people on earth, more time will have elapsed for them then for you. Hence, you can say (sorta) that you "traveled into the future."

Answer 2

OK first off if something is a theory it hasn't been proven secondly you can not travel the speed of light to get into the future you don't become massive your energy is turned into mass you know e=MC2 that is to say energy = mass x the speed of light the faster you go the more mass you must use to create energy to go faster but you cant because the more you produce the more you need until bang! you are no more so yeah a warm whole would be nice too but then your black whole would suck in all the matter around it and you have the problem of escaping the gravity that can move Galaxy's so really i think the only way this is phys-able is through proton acceleration in which you accelerate the protons of an object and pretty much freeze it in time but good luck on not exploding oh and one last thing every sci fi show dealing with time travel teaches us one thing . . . don't mess with time travel you'll only screw stuff up watch the butterfly effect

Answer 3

In reading some of these answers I was struck by the sudden correlation between the light speed travel and the worm hole theories. As an object approaches the speed of light it's mass increases toward infinity. More and more energy is required to accelerate the object. As an object's mass increases, its gravitational field increases. If it were possible to accelerate an object to near light speed, giving it near infinite mass, it would quite possibly gain enough mass to collapse into a black hole. If there were any way to create an artificial wormhole, this would probably be it. Though the amount of energy required to generate a mass that enormous would be astronomical. I still don't think it would allow travel backward in time but who knows what can happen in quantum physics?

Answer 4

Well there's 2 ways that I know of that have been theorized, and 1 has been proven. However there's a catch.

In order to travel into the future, you simply need to travel near the speed of light. If you were in a rocket for a year going near the speed of light many many many years would pass on Earth. This has been proven, of course not nearly fast enough to make a noticable difference hehe. The other problem with this method of time travel is that the closer to the speed of light you go, the more massive you become. In other words as you increase your speed closer to the speed of light in theory your weight would increase to infinity....

The other theory I've heard of is making a wormhole. You would need an amazing amount of gravity; a black hole, to create one. Basically the theory is that if you create a wormhole using a black hold, it will make a "rip" in time and space in which you could travel back to the time you first made that "rip"

So the travel really really fast theory allows you to travel into the future, while the wormhole theory allows you to travel back in time.

Answer 5

OK this is a not exactly a simple question, but lets give it a try. This explanantion is of perforce a simplified one, not least because this is not an area of expertise of mine. But try this...

According to the equations of Albert Einstein's general theory of relativity (the best theory of time and space we have), there is nothing in the laws of physics to prevent time travel. It may be extremely difficult to put into practice; but it is not impossible.

A simple black hole won't do, though.

If such a black hole formed out of a lump of non-rotating material, it would simply sit in space, swallowing up anything that came near it. At the heart of such a black hole there is a point known as a singularity, where space and time cease to exist, and matter is crushed to infinite density.

Thirty years ago, Roger Penrose (now of Oxford University) proved that anything which falls into such a black hole must be drawn into the singularity by its gravitational pull, and also crushed out of existence.

In the 1980s, though, Kip Thorne, of CalTech studied the situation from all sides, but were forced to the conclusion that there really was nothing in the equations to prevent time travel, provided (and it is a big proviso) you have the technology to manipulate black holes. As well as the Kerr solution, there are other kinds of black hole time machine allowed, including setups graphically described as "wormholes", in which a black hole at one place and time is connected to a black hole in another place and time (or the same place at a different time) through a "throat".

Thorne has described some of these possibilities in a recent book, 'Black Holes and Time Warps' (Picador), which is packed with information but far from being an easy read.

Michio Kaku, a professor of physics in New York, has come up with a more accessible variation on the theme with his book 'Hyperspace' (Oxford UP), which (unlike Thorne's book) at least includes some discussion of the contribution of researchers such as Robert Heinlein to the study of time travel.

So to make a Time Machine you would need to be able to control two black holes in different parts of the universe. Linked at the singularity this would let you travel through time and space. Simple. But we are a long way from either a TARDIS or Star Trek style 'Guardian of Forever' as yet.

Answer 6

i have heard of many theories
1)take a body nearly equal to the mass of the earth compressed to the size of a ball and rotate it 2000 times a second. according to a theory of einstien it will elapse the surrounding time and u will reach the future
2) just take a trip to black hole at its center u will find electron sized wormhole, just pour some exotic material itwill enlarge; enough for a person to enter. they will serve as a shortcuts in space time curves. and u will reach to future. this theory is supposed to be able explain how to see the past . as the light that were reflected ages ago by earth can be caught and seen. its quite amazing concept which explain we can go to the future and see the past ....... moreover this theory arises the idea of traversable shortcurts from one galaxy to the next
3)time curves over heavy masses and u need to increase ur mass (probably by travelling in the speed of light be careful this may cause a dilation in time too.) this will too take u to future.
4)take two heavy masses each at the opposite of space curvature rotating very fast in space in opposite direction this will cause a tear in space through which u willbe able to travel to the two mass stations following a shortcut space path i.e.u have reached the future
5)choose a very high gravity region .... according to einstiens theory these regions are capable to constrict space in between them(which is also the actual cause planets start the revolution.) this property is useful to constrict time and even tear the space whenthey are paired with another similiar regionin next part of space curve... this can take u tofuture. fast moving nature would be an additional advantage.
6)travel in the speed of light but donot let urmass turn infinity this will dilate time this willtake u to past than the earth time.
7)if u need to constrict time and goto future rotate very fast,as time constricts and curves over fast rotating objects. but if u want to go to past follow 6)

Answer 7

First you need a Delorian. Then you need some refined Plutonium to create 1.21 Gigawatts to feed into the flux capacitor (did I mention you need a flux capacitor?) And don't forget to make sure your time circuits aren't damaged, how many times do I have to tell you people!

Answer 8

Stephen Hawking's chronological protection conjecture holds that the laws of physics disallow time machines. However, lets think for a moment before jumping to a hasty conclusion.

There have been some toy experiments in which, at just the moment that the time machine is actuated, the universe conspires to blow it up, which has led Hawking and others to conclude that nature will contrive it so that time travel never in fact occurs. But NO ONE actually knows that this is the case, and it cannot be known until we have a FULL theory of quantum gravity, which we do not seem to be on the verge of yet.

One of Hawking's arguments in the conjecture is that we are not awash in thousands of time travelers from the future, and therefore time travel is impossible. This argument I find very dubious, and it reminds me very much of the argument that there cannot be intelligences elsewhere in space, because otherwise the Earth would be awash in aliens. I can think half a dozen ways in which we could not be awash in time travelers, and still time travel is possible.

First of all, it might be that you can build a time machine to go into the future, but not into the past, and we don't know about it because we haven't yet invented that time machine. Secondly, it might be that time travel into the past is possible, but they haven't gotten to our time yet, they're very far in the future and the further back in time you go, the more expensive it is. Thirdly, maybe backward time travel is possible, but only up to the moment that time travel is invented. We haven't invented it yet, so they can't come to us. They can come to as far back as whatever it would be, say A.D. 2300, but not further back in time.

Then there's the possibility that they're here alright, but we don't see them. They have perfect invisibility cloaks or something. If they have such highly developed technology, then why not? Then there's the possibility that they're here and we do see them, but we call them something else—UFOs or ghosts or hobgoblins or fairies or something like that. Finally, there's the possibility that time travel is perfectly possible, but it requires a great advance in our technology, and human civilization will destroy itself before time travelers invent it.

I'm sure there are other possibilities as well, but if you just think of that range of possibilities, I don't think the fact that we're not obviously being visited by time travelers shows that time travel is impossible.

A profound consequence of Einstein's special theory of relativity is that no material object can travel as fast as light. It is forbidden. There is a commandment: Thou shalt not travel at the speed of light, and there's nothing we can do to travel that fast.

The reason this is connected with time travel is because another consequence of special relativity is that time, as measured by the speeding space traveler, slows down compared to time as measured by a friend left home on Earth. This is sometimes described as the "twin paradox": two identical twins, one of whom goes off on a voyage close to the speed of light, and the other one stays home. When the space-traveling twin returns home, he or she has aged only a little, while the twin who has remained at home has aged at the regular pace. So we have two identical twins who may be decades apart in age. Or maybe the traveling twin returns in the far future, if you go close enough to the speed of light, and everybody he knows, everybody he ever heard of has died, and it's a very different civilization.

It's an intriguing idea, and it underscores the fact that time travel into the indefinite future is consistent with the laws of nature. It's only travel backwards in time that is the source of the debate and the tingling sensations that physicists and science-fiction readers delight in.

I don't know that my answer to what I hope was a somewhat sincere question has brought time travel a step closer. But maybe the joint effort of all those involved in this debate has at least increased the respectability of serious consideration of the possibility of time travel. As a youngster who was fascinated by the possibility of time travel in the science-fiction novels of H.G. Wells, Robert Heinlein, and others, to be in any way involved in the possible actualization of time travel is very exciting. Of course we're not really at that stage; we don't know that time travel is even possible, and if it is, we certainly haven't developed the time machine. But it's a stunning fact that we have now reached a stage in our understanding of nature where this is even a bare possibility...

Answer 9

airplanes are time machines.... if your flying in the oposite as the rotation of the earth (west ) you are traveling backward in time as it will be an earlier time in the zone you are in (posably landing at an earlier time than u left home!).... if you travel with the rotation (east) but faster than the rotation your are traveling forward in time hence moving to a later timezone (will be later when u land than the travel time would equate to).
