Is there a physical phenomenon that could be used to record digital information in such a way that it has the following properties:
it relies on some immutable physical law and does not rely on any third party authority, neither centralized nor distributed
it is associated with a physical absolute time stamp (the time stamp can be translated into physical clock time with some fixed and useful time resolution (e.g. no worse than x hours, or 1 day))
the time stamp is immutable (it cannot be changed later, without detection)
the time stamp is unique (for some fixed resolution, no two time stamps are identical)
any existing time stamp is uncopyable (it cannot be recreated at a later time, without detection)
any future time stamp is not pre-constructible (it cannot be forged ahead of time)
there is a method for checking time stamp seriality (times stamps s and t can be shown to be generated by a specific source of such time stamps, and can be reliably ordered based on some physical principle)
[optional] it is global (i.e., time stamps can be used across more than one instance of the time stamper)
[optional] it is feasible as a technology (i.e., does not involve taking images with a telescope or via high energy physics experiment)
[optional] resilient to certain classes of failures (e.g. inaccessibility of any third party infrastructure)
If this is not possible, I would be interested in learning why. If it is possible, I would be interested in examples of phenomena that could be leveraged. In either case, I would appreciate simple-language explanations, with document links for mathematical details.
Thank you in advance for spending any time on this, and apologies if you don't consider this question to be on topic.
Update 1: @AndersSandberg pointed me to an interested paper by Haber and Stornetta (https://www.anf.es/pdf/Haber_Stornetta.pdf). On cursory reading, I suspect that it violates some of the conditions I mentioned above. Nevertheless, it's an elegant (blockchainish) idea.
