Light clocks A and B moving horizontally through
space. According to length contraction, clock A should tick faster than
clock B. In a new study, scientists argue that there is no length
contraction, and both clocks should tick at the same rate in accordance
with special relativity. Image credit: Sorli and Fiscaletti.
(Phys.org) -- Philosophers have debated the nature of time
long before Einstein and modern physics. But in the 106 years since
Einstein, the prevailing view in physics has been that time serves as
the fourth dimension of space, an arena represented mathematically as 4D
Minkowski spacetime. However, some scientists, including Amrit Sorli
and Davide Fiscaletti, founders of the Space Life Institute in Slovenia,
argue that time exists completely independent from space. In a new
study, Sorli and Fiscaletti have shown that two phenomena of special
relativity - time dilation and length contraction - can be better
described within the framework of a 3D space with time as the quantity
used to measure change (i.e., photon motion) in this space.
