How can time be slower and faster at the same time? Thanks to http://www.audible.com/minutephysics for supporting MinutePhysics This video is about the famous “Twin paradox” of special...
========== One of the most revolutionary things we learned
in the 20th century was that time is not absolute– the rate at which time passes for you
(or anything else in the universe) is differentdepending on how fast you're moving and how
much you're accelerating.In particular: time passes slower the more
you're moving.This fact has been confirmed experimentally
countless times – fast-moving muons takelonger to decay, light emitted from a moving
source has a lower frequency , and so on.But relativity of time can at first glance
seem somewhat contradictory.Suppose we're flying past each other; from
my perspective it seems like you're moving(and so time should go more slowly for you),
and from your perspective it seems like I'mmov...
