jb manchak.

i am a philosopher at uc irvine.
for the most part, i think about space and time.

my cv is here.

a recent book is here.

some published papers:

on privileged coordinates and kleinian methods
what do privileged coordinates tell us about structure?
heraclitus-maximal worlds
on coordinates and spacetime structure
time machines
a hierarchy of spacetime symmetries: holes to heraclitus
closing the hole argument
on comparing amounts of mathematical structure
on the (in?)stability of spacetime inextendibility
general relativity as a collection of collections of models
on feyerabend, general relativity, and unreasonable universes
malament-hogarth machines
a remark on time machines in honor of howard stein
why be regular?
some no-hole spacetime properties are unstable
space and time
would two dimensions be world enough for spacetime?
(information) paradox regained?
on the inextendibility of spacetime
on gödel and the ideality of time
is the universe as large as it can be?
supertasks
epistemic holes in spacetime
time (hole?) machines
on spacetime singularities, holes, and extensions
the geometry of conventionality
global spacetime structure
essay review of malament (2012)
time travel: why it may not pay to work out all the kinks
what is a physically reasonable spacetime?
no no-go: a remark on time machines
on efficient time travel in gödel spacetime
on the possibility of supertasks in general relativity
on the existence of time machines in general relativity
