century ago profound discoveries were made about our cosmos. As well as Albert
Einstein’s epochal formula E0=Mc2, Special
Relativity - the basis of General Relativity - uncovered an
even more astonishing insight: One can travel into the future.
Not of oneself, but of other people.
With the help of a simple approach to Space-Time visualization
(and a little school maths), this first Time Travel lecture will show graphically how a medieval
principle of simple motion leads to both of these revelations neatly -
and understandably - fitting in with physical reality and how
‘Providence’ cleverly limits the maximum speed any object can travel
(thereby also preventing us from going backwards in time). The kinematic
twin paradox scenario will be properly explained, showing how one twin
can ‘slow down’ his or her biological aging.
As well as dealing with some rather
neglected Irish and Russian relativity history, the
lecture will also present some quite new facts: an easy (but expensive) way to measure - rather than assume -
what the limit speed of the Universe is, and a radically new shortcut to
Einstein’s mass-to-energy formula. Both of these approaches have
appeared in a physics journal (details below), but still require only school maths for their understanding.
The second lecture in November – the
Space-TimeS Cosmographicum - will focus on an innovative way of
visualizing the very essence of Special Relativity and cover the more
involved dynamic twin paradox.
It will demonstrate (for example) how home ‘contemporaries’ age exponentially
compared with an accelerating rocket’s passengers who however could
never seem to exceed a certain distance from their point of departure
because they would perceive their
‘ever-increasing’ distance away as continually ‘contracting’
(the Dubliner FitzGerald’s famous 1889 contraction theory).
