| Feb 2, 2016 at 8:51 | comment | added | bright magus | @PieterGeerkens: "NO-ONE KNOWS WHAT INERTIAL MASS IS". Actually, no-one knows nothing. Only the Maker does. Humans can only have theories. Now, Einstein was very close. He probably didn't dare to take his equivalence pronciple literally and propose that (all) matter is expanding, solving several problems, such as unexplainable mechanism of attraction, free-fall or the identity of inertial and gravitational mass. In order to move matter one needs to work against its innate acceleration. The thing is no-one (in the mainstream) is ready to dump curved space(time) and such. | |

| Apr 15, 2013 at 5:37 | comment | added | Manishearth | @Force He doesn't seem to be mocking the question here. He's just addressing a single point in the question, that's all. | |
| Apr 15, 2013 at 1:53 | comment | added | Pieter Geerkens | @Force: I am rarely accused of having tact. I believe your question has merit at its core, but that this is being obscured by the creation of phantom windmills to tilt at. Feynman died over 25 years ago, so maybe his is not the last word on the subject. If you improve your question, You might attract answers from community members more knowledgeable, and current, than myself. | |
| Apr 15, 2013 at 1:47 | comment | added | Force | Then you should have simply answered with "No one knows what inertial mass is" instead of mocking the question. Which if troubled you as such, you should of simply avoided answering it. | |
| Apr 15, 2013 at 1:30 | comment | added | Pieter Geerkens | And my point is that you are apparently inventing windmills solely for the purpose of tilting at them. Your question is much more interesting if you work from the existing acknowledgement that NO-ONE KNOWS WHAT INERTIAL MASS IS. Feynman famously admitted as much in his memoirs. It is believed to be identical to gravitational mass solely on a preponderance of empirical evidence, with no theoretical basis whatsoever. | |
