Acceleration slows biological aging?

Question

According to the long-resolved so-called twin paradox, one twin flies away and returns younger than the other twin.

The resolution is that one undergoes acceleration, the other does not. (3 different inertial frames are considered, when SR applies to only two)

From this, I suppose one could conclude that the acceleration/deceleration *causes* one to age slower, no?

Answer 1

All paths through spacetime that connect the same two events are of equal length in four-space. The difference is the relative sizes of the components of that length. Some will cross more space and experience less time between the two events. Others will cross less space and experience more time. The acceleration vectors that each observer uses while going from Event 1 to Event 2 determines how much space and how much time each of them will measure.

The two events being connected are the handshake the twins gave each other before departure and the other handshake they greeted each other with when the spaceship came back home. The travelling twin was accelerated through space and returned to Earth to meet the stay-home twin.

The four-space paths connecting the two handshakes is of equal length through spacetime, but the accelerations of the travelling twin loaded more of the magnitude of his path into space leaving less of it in time, while the stay-home twin's path was nearly all through time.

Answer 2

The aging is "slower" only relative to the stationary person. But for the twin in acceleration, the aging is "normal" in his frame of reference.

Answer 3

It's the velocity induced by the acceleration that causes the age difference, not the acceleration itself. Sqrt( v^2 / c^2 -1)

Answer 4

According to Albert's theory, ALL molecular process slow down due to extreem volocity, acceleration and/or gravitational fields - and that includes biological processes - i.e. aging.
And there you have the "twin paradox" in a nutshell.

Answer 5

I understand what you're saying, yet with the help of no ability am I going to bypass into element, as i do no longer recognize a lot of this technology communicate. yet, what you're saying makes some type of expertise, that's like searching up on the sky and seeing the celebrities, a number of that were lengthy burned out. this kind of lag would have interfered with Astra's chronometer, searching on how speedily she replaced into vacationing faraway from earth. So briefly, my opinion is that the universe a at the same time as homogeneously, because the speed at which undemanding travels from distance to distance would not actual advise it truly is older or youthful, merely that it hasn't been considered with the help of our eyes yet.

Answer 6

The one critical term you left out is "relative to." Relative to each other the two twins age differently, but as far as each individual twin is concerned their biological aging is normal.

Answer 7

yes and no

yes u wiil live longer then others(ur twin) couse o space/time dialtation

but it dosent not efect in any way de aging process at molecular level

here is how u can
