Albert Einstein, special relativity, and an afterlife: this is heavy

Is your dead grandmother… still alive? The answer is…
… yes…
… in a sense.
That’s if information in the cosmos is never destroyed, but rather… rearranged. In this case the information I refer to are the atoms, sub-atomic particles, and who knows what else, that make up everything in the universe, including us, and our predeceased family members.
Interaction with this information, which over eons diffuses into the cosmos after our deaths, may then be possible if cosmic consciousnesses, being ours — somehow — come into being one day, and are able to envelope the universe, and eventually encounter your late grandmother’s information.
This is the understanding I took away from this Big Think video featuring German theoretical physicist Sabine Hossenfelder, which I saw on Open Culture. Best you watch for yourself though, and see what you make of it, as matters of maths and physics are not my thing. Otherwise, some fodder for a little contemplative thinking this weekend, perhaps?

How can nothing unreal exist in a not locally real universe?
10 October 2022
In addition to Annie Ernaux being named the Nobel Prize literature laureate , John Clauser, Alain Aspect, and Anton Zeilinger, received the Nobel for their contributions to physics this year. I studied physics in high-school for an ill-fated year, and struggled to make sense of any of it. Way too mathematical. And maybe way too weird.
All the more so, given the Nobel award winning work of Clauser, Aspect, and Zeilinger, effectively “overthrows reality as we know it.” This outcome spans the previous study of a whose-who of household names in the realm of physics, including John Stewart Bell, Boris Podolsky, Nathan Rosen, John von Neumann, and of course, Albert Einstein.
Quantum mechanics’ problem of nonlocal realism would languish in a complacent stupor for another three decades until being decisively shattered by Bell. From the start of his career, Bell was bothered by the quantum orthodoxy and sympathetic toward hidden variable theories. Inspiration struck him in 1952, when he learned of a viable nonlocal hidden-variable interpretation of quantum mechanics devised by fellow physicist David Bohm — something von Neumann had claimed was impossible. Bell mulled the ideas over for years, as a side project to his main job working as a particle physicist at CERN.
