  • Hmm, but what if the Earth has not been destroyed by a singularity yet?

    We are at the center of what we can observe, obviously, but assuming that everything (including what we can not observe) is within the event horizon of a singularity then what we can observe may all be experiencing the same (relative) spacetime curvature and is apparently “expanding” because it is accelerating as it falls deeper into the singularity.

    I’m kind of thinking of the classic spacetime expansion demo of dots on the surface of a balloon, extended into 3(+?) dimensions… the singularity (the balloon) is expanding as we (and everything else) are drawn further into it, resulting in the objects we can see (the observable universe) appearing to accelerate away from us. The actual center of the singularity is so far away that we can’t observe it, and the acceleration appears (locally) uniform to us in the same way that the surface of an infinite-radius sphere would appear flat.

    There’s probably some obvious physics reason this doesn’t work in reality, but I don’t know what it is.

    There’s not a singularity at the center of our observable universe, though.

    Well, er, how would you know?

    Perhaps the space inside the event horizon is so large, and the distance to the singularity so great, that the expansion we observe from our reference point appears uniform.




  • So yes but… there are still no good alternatives to Active Directory in the context of managing IT for an organization with 10,000+ users, thousands of endpoints, and millions of files which need to maintain proper association with individual user accounts and be delivered to specific endpoints on demand.

    Google Workspace is the most feature-rich competitor, but it is a pale shadow of the level of IT infrastructure that Microsoft’s ecosystem provides.

    For Microsoft to fade away, someone needs to build a competing large-scale IT management system that provides the same kind of functionality that Active Directory does.
