What is the tipler cylinder
The Tipler cylinder
In 1974 the American mathematical physicist and cosmologist Frank Tiplers discovered, while analysing their solution, an enormous cylinder of infinite length that rotates along its long axis at high speed and could allow time travel.
When a high-speed object in space moves through a vacuum, it creates its own gravitation field. The shape of that field changes as time passes. Physicist Frank J. Tipler has proposed that such an object could also create an infinite, self-sustaining version of itself; not merely on one plane but around a series of curved surfaces. This theoretical structure is called a Tipler cylinder.
The idea was first proposed by physicist Frank J. Tipler in his 1994 book The Physics of Immortality . He suggested that if scientists could copy a person's mind onto a computer, then he or she could be resurrected from inside a computer when technology becomes advanced enough to create human-like intelligence in computers. One proposal for doing so involves nanotechnology machines called oracles, which would use quantum processes to simulate and improve upon brain functions. Scientists at Max Planck Institute for Gravitational Physics , however, have come up with another way: Create one giant supercomputer capable of mimicking all physical processes that happen on Earth.

This 3D shape could be the key to time travel
Physicists say a cone-shaped object called a Tipler cylinder could theoretically allow for time travel. A report published on io9 explains that it all has to do with what happens when one loops gravity into space-time, tying it back into itself. Theoretically, by taking advantage of those properties we could create closed timelike curves. And who would want to create such things? Travelers from the future and other dimensions—if that's not sci-fi enough for you, try reading up on wormholes.
Physicists have proposed a new way to think about time. In an experiment, they sent a particle of light back in time. And it's due to a cylinder with two openings, one at each end. It sounds confusing, but stick with us - because if you have any interest in physics or time travel (who doesn't?), then it might just be your favourite thing you read today.
Parts of the tipler cylinder
The cylinder begins with a torus which has been deformed in such a way that one of its rings sticks out to become its own little donut-shaped ring. The cylinder next consists of an outer ring of normal space and time, and an inner torus of warped space-time. Our Universe lies between these two parts, in what could be called inner space. According to [Physicist Frank] J. Tipler, we can think of it as being another circle wrapped on top of our three dimensions of normal space. This fourth dimension (the circle) contains all possible points at once because it moves very fast in relation to us - or vice versa, depending on how you look at it.
How A Tipler Cylinder Works
Imagine two nested coaxial cylinders, each of which has its own axis of symmetry. One cylinder is inside the other and both cylinders have a radius of one meter. In terms of volume, therefore, each cylinder contains about 439 cubic meters. If there were no air in either cylinder and if both cylinders were placed next to each other with their axis parallel to one another, then at least from a geometric perspective there's no reason why they should attract or repel. It seems as though they should just sit there like bookends without doing anything much at all.
You have to figure out how to spin a cylinder at several billion revolutions per minute. Well, for this cylinder to work, its length must be infinite. Before we get into explaining how this time machine works, let me give you a little background.
In 1948, Kurt Gödel worked with general relativity to obtain equations that suggested time travel to the past. He proved that a rotating universe, in accordance with Einstein's theory, will allow you to travel in time.
However, Stephen Hawking proved that time travel won't work with a finished cylinder if you don't have negative energy (which is unlikely).
If you try to make a complete cylinder, you have to deal with foreign matter and its negative energy. To make the cylinder work, you need about ten times the mass of the sun and a lot.
The mass of the cylinder should not be less than the mass of the sun, but it must be tightly packed together.
Then you have to launch it faster and faster until it spins so fast that it begins to disturb the fabric of space and time - and you can detect the flow of gravitational waves emanating from this structure.
You have to make this supermassive and super dense object spin a billion times per second. However, no matter how this effect is achieved, the massive gravitational force of the cylinder combined with the fast rotation will create the effect of frame drag.
Once a cylinder is spinning fast enough, the nearest spacecraft (if it follows a very precise spiral around that cylinder) can travel billions of years in the past and several galaxies far away.
When you get close enough to the most distorted cylinder in time and space, you will fly around it a few times, then fly back to the earth, back in time.
How far in the past depends on how many times you have walked around the cylinder. Your path will usually force you to move forward in time, but as you move around the cylinder in the direction of rotation will cause you to go back in time, your path will change.
The machine turns the direction of time into the past, so the longer you follow the rotation of the machines, the further back in time you will go.
To return motion to normal, simply step away from the cylinder, return to Earth, and you will return to the present, albeit to the present in the past.
The danger of time distortions is that if the traveler is receding into the past, any changes quickly "fluctuate" over time and thus affect the traveler.
Basically, if you rotate around the cylinder in one direction, you can go back in time, and if you go in the opposite direction, you can move forward in time.
Your path moves with time, and changes in the movement of the cylinder due to the direction of rotation make you move back and forth in time.
You have to rotate the cylinder, and when it rotates, it will start to disturb the structure of space-time so that it can detect the gravitational waves emanating from it.
In order for this cylinder to work, you need matter that is about 10 times the mass of the Sun (so VERY matter). Then you will need to roll this fabric into a very long and very dense cylinder.
This superdense cylinder will look a bit like a black hole that went through a spaghetti factory (so you can imagine the technology it would take to create that density).
Tipler argued that a cylinder can create closed curves similar to time if the rotational speed is high enough, at least a few billion revolutions per minute.
Tipler suggests that the finished cylinder can achieve the same effect if its rotational speed is increased significantly.
Tipler's original solution was for a cylinder of infinite length, which is easier to analyze mathematically, and although Tipler suggested that a finite cylinder could create closed time curves if the rotational speed were high enough, not, he demonstrated.
Stephen Hawking showed that negative energy is a prerequisite for creating a closed time curve by manipulating gravitational fields in a finite region of space; this shows, for example, that a finished Tipler cylinder cannot be used as a time machine.
Now that you have finally assembled a Tipler cylinder, it should spin at an unimaginable speed, billions of times per minute. To use Tipler's time machine, you must leave the earth in a spacecraft and go to the point where the cylinder rotates in space.
To use the Tipler time machine, leave the earth in the spacecraft, and then go to the rotating cylinder in space.
The Tipler cylinder, also known as the Tipler time machine, is a hypothetical object that is theoretically regarded as a potential mode of time travel, although the results show that the Tipler cylinder can only be allowed if its length is infinite or there is energy. Time travel.
Tipler Cylinder, also known as Tipler Time Machine, is a hypothetical object, theoretically considered as a potential mode of time travel, this method is considered useful for modern humans to understand physics, especially general relativity, although later Research has shown that Tipler can only allow time travel if the length of the cylinder is infinite (see the discussion of Hawkins' theorem below).
In 1974, Tipler showed in his paper "The Rotating Cylinder and the Possibility of Global Causality Erosion" that space-time contains a long and huge cylinder that rotates around its longitudinal axis and produces an adhesion effect with the frame.
Although Tiplers' paper originally proposed that the length of the cylinder can be infinite, recent calculations show that it can still work even if it is "only" a few thousand miles long. Tipler's cylindrical method is called Tipler's time machine because a hypothetical object is theoretically regarded as a potential way of time travel-this method will apply to our current understanding of physics, especially the theory of relativity. In general, although recent results indicate that even if its length is infinite, the device can allow time travel
