What is the reason for the asymmetry between the twins in the

the paradox must lie hidden somewhere inside the steps of its derivation within T1. Solving the paradox can thus only come from an exacting scrutiny of these steps. Consequently, there must exist a solution for the twin paradox P1 2 T1 within T1. This solution will not invoke accelerations to explain the paradox P1 2T1, because T1 does not

2006). So called twin paradox, which states, that one of the twins after spaceflight returns home younger than that, which stays on the Earth because of diferences in time flow or acceleration , received especialy harsh critique. Interesting therefore is to see, that here is

Variations on the Twin Paradox - LSU

variations to the twin paradox and the related triplet paradox. The Twin Paradox One of the two twins goes off in the direction opposite to the Earth s rotation around the Sun in a spaceship, and starts lagging it further and further. To do so, it must accelerate and then at some point decelerate to establish its orbit.

Time Dilation, the Twin Paradox and all that

The twin paradox challenges time dilation by suggesting that a contradiction follows from the symmetry of the effect. As an example of the paradox, consider the case of two twins, Roy and Ernie. Roy takes a relativistically-fast rocket ride to a nearby star and back. For the quantitative case we consider shortly, Roy s rocket travels V = 0.86c.

The Twin Paradox

paradox) is the most famous and has been the most controversial. Anthony Philip French (1920 2017) (New York: Special Relativity, Massachusetts Institute of Technology, 1966, page 154) The twin paradox is a thought experiment in SR (special relativity) involving two identical twins A (for Alice) and B (for Bob).

Note that the mere existence of anyphysical symmetry-breaker implies the descriptive invalidity of the mathematically symmetrical LT. On this point the LT is completely inflexible.

example the twin paradox that is arguably the most famous thought experiment in relativity theory. In this supposed paradox, one of two twins travels at near the speed of light to a distant star and returns to Earth. Relativity dictates that when he comes back, he is younger than his identical twin

Introduction A puzzled colleague wrote to the author recently regarding the twins paradox, On the one hand, I think that the situation is well understood, and adequately explained in plenty of textbooks. On the other hand there are

The Traveling Twins Paradox -

The new paradox, termed the Traveling Twins Paradox (TTP) is as follows: Consider the case of two twins, A and B. Assume that A is located at coordinate x= + (l+ ∆l) along the x axis, and B is located at coordinate x= (l+ ∆l) along the same axis. Assume that the twins start moving toward each other using identical vehicles.

Correct Resolution of the Twin Paradox

II. The Twin Paradox Here s a statement of the Twin Paradox , designed to make it seem paradoxical: Suppose that two identical twins start out on Earth, the same age. One of them gets in a spacesh ip and flies around really fast. Call this one Space Twin The other twin, Earth Twin , stays on Earth the whole time.

The Twins Paradox - University of Richmond

The Twins Paradox Consider two twins. One sets out at the age of 25 on a spaceship from Earth at a speed of 0.99c where c is the speed of light. The Earthbound twin goes on about his business accumulating the normal acoutrements of advancing age (gray hair, drooping body parts, etc.). After twenty years have passed for the Earthbound twin, the

Analyzing the Twin Paradox

It becomes the Twin Paradox when the observers are considered to be a pair of identical 30-year-old twins, and Twin-A stays at home on Earth while Twin-B travels at 99.498833956657% of the speed of light to another star and back. Because time moved slower

Symmetrical Experiments to Test the Clock Paradox

Jack gets to sit on Earth and twist his thumbs, the situations for the twins are asymmetrical, and therefore no paradox. It turns out, magically, that the poor hard working brother John, who has to suffer all the ordeal of mechanical shock, long term fatigue and loneliness, lives happier and stays younger than his twin brother Jack.

The Twins Paradox 1 Intriguing biological consequence of time dilation Consider a set of 20 year old twins named Speedo and Goslo. Speedo takes a round trip to a planet 20 light years from Earth on a spaceship with a speed of 0.95c. When he returns to Earth, he nds that his brother has aged 42 years while he has aged only 13 years.

Frank remains on earth. ¾Frank sees Mary s clock running slow hence she is younger than Frank on return. ¾Mary sees Frank s clock running slow hence he is younger than Mary on

4 Paradoxes of special relativity

This is a simple version of the Twin Paradox, so called because the classic version of the paradox imagines two twins setting off in rockets going in opposite directions: it seems that it would be true for each to say that she is aging more quickly than her twin. But surely two people can t each be older than each other!

the resolution of the twin paradox [12 23]. 3. The twin paradox Two twins Eartha and Stella meet at an event P1, move away from each other, and then meet again at a later event P2. Eartha considers herself as at rest and predicts that Stella is younger than herself at P2 due to the relativistic time dilation.

The Twin Paradox in a Compact Space

The Twin Paradox in a Compact Space Joshua Albert December 17, 2007 1 Introduction The twin paradox is a well known puzzle for young physicists to ponder. The setup is simple. Two twins decide to go separate ways, one will stay home on Earth, the other will fly on a spaceship traveling at high speeds away from Earth, and then turn around and

Twin paradox in de Sitter spacetime

May 18, 2019 term paradox , however, is quite misleading, as all ramifications of the situation considered are well understood nowadays. Nevertheless, we use this term to sketch the basic situation of this paper. While one of the twins, we will call him Eric, stays on Earth, the other twin, Tina,

O. 2) In two di erent I.F. s, O0 1 and O0 2. Blind application of time dilation leads to contradiction. Actually, O0does see O-clock run slowly, but there is

Twin Paradox- the role of acceleration - Miami

What is the twin paradox The twin paradox is as old as special relativity. A pair of twins, A and B, synchronize their clocks, and then B moves away (usually at a very fast velocity) to a distant object, and then returns to A, we find B is younger than A. B journey consists of a short period of acceleration followed

The Twin Paradox Resolved

The paradox of the twins dates from Einstein s first paper on relativity (Einstein, 1905), although he only alluded there to a peculiar consequence of his theory which didn t involve a re-uniting of twins, just distant clocks becoming un-synchronized by one s acceleration. The

years! Now both twins think the other is younger, paradox? Well fortunately enough, no. This analysis has assumed symmetry in the problem when there is clearly asymmetry. To return to Earth, Adelle has to undergo considerable acceleration in the Tau Ceti system which means she no longer occupies an inertial frame of reference.

says higher speeds increase existence. So the story of the twins paradox is possible. Origin of the muon particle in the atmosphere at 9000m The normal muon at rest lives 2.2 microseconds and with this life only would travel 600 m, but when accelerated to 99.8045% c your life increases 35 microseconds Muon detected

On the Ingredients of the Twin Paradox - ELTE

A rapid review of the twin paradox is given in Sect. 2. To begin with, Sect. 3 considers a confusion at the origin of the famous paradox; in order to preserve a long used terminology, the paradox appellation is re-defined. Then, for the sake of a later geometrical synthesis, the closely related Thomas-Wigner rotations phenomenon is introduced.

He called his theory Relativity

The Twin Paradox Twins are born on earth. One of them decides to travel at great speed to a distance star and then return home to earth. Her twin stays at home. When the traveling twin returns home, both twins stand side by side and compare ages. The traveled twin should be younger than the

What the Global Positioning System Tells Us about the Twin s

Introducing the twins The twin s paradox is an illustration of the complexity of SR s interpretations of nature. Suppose two identical twins start out at some common instant. One remains on Earth. The other (the traveler ) is on a spacecraft headed for Alpha Centauri (AC) four light-years away


The Twin Paradox is a thought experiment in Special Relativity, in which the ages of twins are compared after one has made a high speed journey over a long period of time, while the other has remained stationary. The proposed paradox arises because each twin sees the other
