Time dilation is measured relative to which frame of reference?

Question

Twin paradox?

the twins are pregant female just about giving birth relative to earth the time of the moving female to give birth appears as years?

Perhaps it takes a long time for the light signal to get to earth because of the long distance that light has to travel to get the imformation?

Answer 1

Time dilation is a relativistic effect that occurs when you are measuring the passage of time between two reference frames. For example, if you are on a spaceship traveling at near the speed of light away from Earth (as in the twins paradox), you will not notice any change in the passage of time for yourself. But for someone on Earth, they will see that time has slowed down for you. Hence, when you return to Earth, you will have aged less.

This is the twins paradox, where you would think that since all reference frames are relative, the same time dilation would have applied to the person on Earth. This appears to be a paradox if one expects that, according to relativity, either twin may validly claim to be "at rest", and thus each expects that the other twin will age slowly. Like most paradoxes, this occurs because of faulty assumptions. This one happens because one twin undergoes acceleration while the other does not, something that was not taken into account when this twin-paradox story was invented.

Answer 2

In Albert Einstein's theories of relativity time dilation is manifested in two circumstances:

In special relativity, clocks that are moving with respect to an inertial system of observation (the putatively stationary observer) are found to be running slower. This effect is described precisely by the Lorentz transformations.

In general relativity, clocks at lower potentials in a gravitational field-- such as in close proximity to a planet --are found to be running slower.

Time dilation is the phenomenon whereby an observer finds that the rate at which time passes for ("in") an object moving relative to that observer, has decreased--"time has slowed down." Thus a moving clock which is physically identical to the ("stationary") observer's own is observed, specifically by that observer, to be ticking at a comparatively slower rate. Those moving along in parallel with the clock detect no change in their clock-rate. The time dilation phenomenon applies to relatively-moving objects or entities of any and all kinds: not only clocklike mechanisms, but biological aging, decomposition of atomic particles, radioactive emission, thought and sense-perception, and in general any process that manifests change over time. This article discusses the description of the phenomenon most widely accepted by contemporary physics, its treatment in Einsteinian Relativity. Historically, other accounts consistent with the relevant observations have been proposed but are not generally accepted at the present time.

Answer 3

It is usually related to speed. As you near the speed of light, time is dilated. For instance if i was travelling at near the speed of light and you were to see me, I would appear to be standing still from your veiw point. From my veiw point, I would still go about my ways. From your veiw point, you would see time dilation.

Answer 4

time dilation is reciprocal ... it's observed from the stationary frame of reference but the concept of "stationary" is relative.
