20969 | Early Newtonians could not formulate conservation of energy, having no concept of potential energy [Newton, by Papineau] |
14016 | The idea of simultaneity in Special Relativity is full of verificationist assumptions [Bourne] |
14019 | Relativity denies simultaneity, so it needs past, present and future (unlike Presentism) [Bourne] |
17013 | Absolute space is independent, homogeneous and immovable [Newton] |
22915 | Newton needs intervals of time, to define velocity and acceleration [Newton, by Le Poidevin] |
22893 | Newton thought his laws of motion needed absolute time [Newton, by Bardon] |
17012 | Time exists independently, and flows uniformly [Newton] |
14012 | Absolute time, from its own nature, flows equably, without relation to anything external [Newton] |
14013 | Special Relativity allows an absolute past, future, elsewhere and simultaneity [Bourne] |
14015 | No-Futurists believe in past and present, but not future, and say the world grows as facts increase [Bourne] |
14007 | How can presentists talk of 'earlier than', and distinguish past from future? [Bourne] |
14011 | Presentism seems to deny causation, because the cause and the effect can never coexist [Bourne] |
14017 | Since presentists treat the presentness of events as basic, simultaneity should be define by that means [Bourne] |
