Time travel is self-suppressing
Abstract:This paper examines the distinct lack of clear examples of time-travellers and proposes an explanation for their absence without assuming technical barriers to constructing time machines.

Travel on Airless Worlds (2014)
When we get to other worlds how will we get from point A to B? There are no roads on Ceres. No rivers or oceans on the moon. No airports on Enceladus or even air for an airplane to glide on. Until transportation infrastructure is built, suborbital hops seem the way to go. A suborbital […]
