Relativity of young and old
Einstein theory of relativity age
For the clocks used in the experiments, one second is equal to more than a million billion vibrations. I know I can learn much from my elders, I hope they see that they can learn much from me 2. It was. This is especially true for the young, for they spend the first quarter of their life attaining academic qualifications. In the above text, the key criterion was hidden in parentheses: For the dictum "Moving clocks go slower" to hold, you must be an inertial observer. The accelerated twin cannot just apply the simple time dilation formula, while her sibling on Earth can. The year-old taught himself calculus, algebra and geometry in two weeks, and can solve up to numbers of Pi. During his time at the Albert Einstein Institute , he created the Einstein Online website as one of the institute's contributions to the World Year of Physics Einstein year. The researchers found that even a height difference of around 1 foot 33 centimeters causes a measurable change in the passing of time. The equations of general relativity also predict that gravity similarly slows down, or dilates, time. Before anyone rushes to lower elevations, though, the NIST scientists note that these effects are much too small for humans to perceive directly—adding up to approximately 90 billionths of a second over a year lifetime. There's no way around it: At least for some of the time, the travelling twin isn't an inertial observer.
With the help of time dilation - often abbreviated to "moving clocks go slower" - one can try to explain what happens to the twins.
The result is that, in the given situation, the Earth's gravity does not make an appreciable difference.
If she simply would simply coast along with constant speed along a straight line, she could never return to Earth or, in the alternative version, to the other twin's space-station. Creationist research has exposed many of the weaknesses and flaws in evolutionary philosophy, and has provided answers in such areas as geology and biology.
There's no way around it: At least for some of the time, the travelling twin isn't an inertial observer. If we choose situations in which the twins eventual age difference is counted in years, gravity will not matter. For such an observer, special relativity predicts the following: For any moving clock, that observer will come to the conclusion that it is running slower than his own.
Contraception and abortion are the hardware, but the means are not decisive. There are two possible ways to proceed.

The elderly get comfortable with a certain pattern in their lives and do not like this pattern disturbed Young adults on the other hand are much more adaptable to change What it all comes down to is time, experience and most of all the willingness of old and young alike to learn and share with each other. Though the scientists didn't have much doubt that the theories would hold up on these scales, it's important to show that clocks can now detect such small relativistic effects, he said. If we ignore Earth's gravity and treat the twin on Earth as an inertial observer, our results regarding the relative aging of the two twins will be correct, give or take a few fractions of a second. During his time at the Albert Einstein Institute , he created the Einstein Online website as one of the institute's contributions to the World Year of Physics Einstein year. This would eliminate all risks of a pregnancy after the age of For instance, if there are two observers drifting through space, each on his or her own space station, and if those two space stations are in relative motion, then for each observer, the time in the other space station appears to run slower than for himself. Whether it is a clock on another space station floating past or a clock on an engine-driven rocket, in the time it takes for a second to elapse on the observer's own clocks, less than a second will have elapsed on the moving clock.
She's in a gravitational field in which objects fall down instead of remaining at rest. The age is real. Either one can use Einstein's theory of gravity, general relativityand calculate how the gravitational field influences the twin on Earth.

But with the reality revealed by GR, we now know that we have to ask— six days as measured by which clock? For example, if one twin spent 79 years living at an altitude 1 foot higher than her sister, the first twin would end up approximately 90 billionths of a second older, the researchers found.
