If moving clocks advance more slowly, will earth-bound people age more quickly than a space traveller?

Question

I'm trying to understand relativity. I'll buy the slower clock bit, but I still wonder if that directly corresponds to aging...

Answer 1

This phenomenon is often referred to as "the twin paradox" and is based on the Lorentz Factor formula of time dilation.
Time runs slower in a gravitational field (which is synonymous with acceleration) and velocities which are a significant percentage of light.
It is not specific to only certain phenomenon, but is in fact a true slowing of time - all phenomenon slows with the time, from the biological aging processes all the way to the molecular level of matter.
Just about everything about relativity - from the shortening of distances in the direction of travel to the time dilation to the fact that the speed of light is exactly the same for every observer no matter his relative velocity - is counter intuitive and defies our everyday observations.
But then again, it probably isn't any more counter intuitive than in ancient times when people were told that the earth isn't flat, but rather it is a sphere - talk about contrary to observation and everyday experience!
Good question.

Answer 2

Relativity produces countless measurable consequences on orbiting astronauts. 3 relativistic consequences are the time dilation, gravitational frequency shift, and eccentricity consequences. The time dilation result's envisioned by technique of the conception of particular Relativity. the conception states that relative action between 2 clocks will reason the shifting clock to seem slower than the table certain one. subsequently, the clock on board an orbiting spacecraft will lag in the back of an same clock on the floor. Relativity predicts that the clock frequency will be slowed by technique of a element of v^2/(2c^2 )? 10 ^(-10) , or bring about a postpone of about 7 ?s/day, the position the orbital velocity is v = 4 km/s, and c = the speed of sunshine. The time dilation result has been measured and verified utilising the GPS gadget. The results of time % up is via accepted Relativity, which states that a clock in the route of an massive merchandise will be slower than a clock farther away. utilized to the spacecraft, the clocks on the floor are a lot in the route of Earth than the spacecraft ones, causing the spacecraft clocks to seem swifter by technique of a element of five×10^(-10), or about 40 5 ?s/day. Combining the time dilation and time % up result, clocks on the spacecraft tick about 38 ?s/day swifter than clocks on the floor. as well, because spacecraft orbits at the instantaneous are not completely round, their elliptical orbits reason the time dilation and gravitational frequency shift consequences to determination with time. subsequently the astronaut surely a lengthy time period swifter on the spacecraft. do not get too excited nonetheless, the version is tiny. After a million days (2,seven hundred years) in orbit, the astronaut is strictly one 2d older than he may were if he had stayed on the floor.

Answer 3

I don't remeber exactly how it works but yeah that sounds right. The time in the space craft will travel slowier than regular time on Earth so when they get back more time passed on Earth than in the craft. If I remeber right it somehow proportional to the speed they travel at. The closer to the speed of light the slower time in the craft is.

Answer 4

Hi. In a word, yes. Very short lived subatomic particles "live" longer at speed that are close to 'c'.
