### 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

### 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.

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).

In this supposed paradox, one of two twins travels at near the speed of light to a distant star and returns to Earth.

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.

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

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.

### 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!

### 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 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

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.

### 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.
