| Jan 27, 2021 at 12:54 | comment | added | sand1 | Craig Callender has done remarkable work on the topic, including a popular article in Sci.Am. Btw the split does not seem arbitrary as it is clearly seen in a wave equation or the metric in SR. | |
| Jan 27, 2021 at 12:10 | comment | added | Conifold | @armand Treatments of time in QM and general relativity are in tension, but QFT is set in special relativistic spacetime, so it already unifies QM with SR. Taking SR spacetime as basis, there are no two entities to be the same or not ontologically, there is only one. It approximately splits into what we call space and time only in special types of frames we are used to (slow moving), and the split is not ontological, it is an artifice of our limited perspective. But, of course, it is controversial that treatment of time in physics (within spacetime or not) reflects its ontological nature. | |
| Jan 27, 2021 at 11:04 | comment | added | prateek | Unified theory aims to assimilate general relativity within quantum framework while quantum field theory has assimilated special relativity within itself. Though QFT is still incomplete for other reasons. The question here is about the relation between space and time which should be prior to any theory of mechanics. | |
| Jan 27, 2021 at 10:51 | comment | added | armand | All I know is that time in QM and in relativity is irreconcilable. The stakes for a unified theory are so great that if someone had found it we would have heard of it. I am a layman too, just wanted to note that concurrent theories of time do exist. | |
| Jan 27, 2021 at 10:41 | comment | added | prateek | But doesn't quantum field theory treat time and space at par? (Disclaimer: I am still in early stages of learning QFT so my understanding of it can be way off) | |
| Jan 27, 2021 at 10:28 | comment | added | armand | Note that quantum mechanics, which is just as relevant, has a very different conception of time, and the way to reconcile both has not been found yet. | |
