Is the cosmological horizon very slightly gravitationally repulsive?

Question

It seems that Verlinde's emergent gravity model would be explainable if one assumes that the cosmological horizon is very slightly gravitationally repulsive.

This would explain the galaxy rotation curves. The result would be similar to MOND.

Is this the case?

Edit:

For a lone body, no such repulsion can exist. Each body has its own cosmological horizon. But could it be that a body near a large mass is pushed by the horizon towards that large mass? Obviously, the effect should be small and be noticeable only for galactic distances and large masses. 

In other words, could it be that the cosmological horizon creates a very shallow effective potential that rises a little bit at its distant position?

Dear Physics faculty and grad students,

I have taken a deep dive into AI models. The new GROK 4 has made superhuman advances in artificial intelligence, surpassing ChatGPT, Claude, Gemini, CoPilot, DeepSeek, etc.

The experts predict that within the next 12 months, some of these AI models may be discovering new physics and technologies. Already several new drugs were discovered and placed into clinical trials several years ahead of time because of the computational pharmacology involved.

Today, I challenged GROK 4 to synthesize the Unified Field Theory (theory of everything, unifying General Relativity and Quantum Mechanics). GROK invented a Quantum Geometric Algebra (QGA) to lay the foundation for such a unifying theory.

I was wondering, if you're not too busy right now, if you could take a look at the basic postulates of this theory, and let me know what the biggest flaws or deficiencies might be?

Here is the basic theory of QGA. (shared link too:  https://grok.com/share/bGVnYWN5_f704167a-92f2-4680-b149-33b4be181527
