If two universes have a perfect 1:1 correspondence, can they be both identical and distinct?

In philosophy, can two things be completely indistinguishable from one another, and yet still be two separate things?

Let's assume there exists an exact replica of our universe, but in which the value of every property is inverted in some way. Temperature would be one of these properties. However, the properties which contribute to a sense of hotness and coldness have themselves been inverted, as have the meanings associated with those properties. Something which is hot in our universe would be cold in the other, but the traits which contribute to coldness in our universe are those which contribute to hotness in the other, and vice versa.

Each universe maintains a perfect 1:1 correspondence for every property and relation. The flipped universe would appear completely normal to its inhabitants, because the relations between concepts are preserved.

If every property, concept and relation corresponds perfectly between the two universes, what would distinguish them? Would they be considered different universes, or just two different ways of referring to the same one?

Could they somehow be both identical and distinct, or is that a logical impossibility? Is there a concept in philosophy which deals with this?

Hi new to Taobao, need help

Hi there, I'm new to Taobao and saw many people spending millions of tokens on expensive frontier models for less than a dollar, I tried to sign up for Taobao but the captcha is a pain, after somehow solving it, I got ratelimited (happend twice) regardless I don't know where the cheaper or trustworthy people are, so I wanted to know if any locals or pros could help me purchase cheap tokens (claude and gpt) for me? I can also pay I bit extra for your work. Thanks for reading.

Well the time has come to cancel my copilot subscription, it is really a shame, it was a beautiful tool that allowed developers to access frontier AI models for basically nothing, but now due to AI inflation and enshittification of GitHub Copilot (moving to usage based billings with expiring credits, vendor lock in and no additional benefits), I'm moving away, right now my top contenders are:

  1. OpenAI Codex due to 20$/mo plan that includes GPT 5.5 a well-versed model and more models (gpt-5.5-codex and gpt-5.6) coming soon.

  2. Claude Pro / Claude Code, really explains itself but still poor usage limits.6

  3. OpenCode Zen/Go great sub, access to many cheap frontier Chinese models that perform amazing.

I'm interested in seeing where you are moving next as well, I need some recommendations for any AI product that has something similar to PRUs in Copilot with frontier models and decent rate limits.

It's sad to see such a good product go, but the good flowers are picked first, goodbye Copilot.

I don't know if this was posted yet but all models in GitHub copilot will have a significantly higher premium request quota and say bye bye to free models for all plans, we thought the 7.5x multiplier was bad, just take a look at this
