Quantifying Negative Energy from Entropy

Click For Summary
SUMMARY

The discussion centers on the relationship between entropy and negative energy, particularly in the context of cosmology and spacetime. Participants inquire about the calculation of negative energy derived from entropy, especially at event horizons where maximal entropy occurs. The consensus indicates that while this concept is under investigation in recent research, it is not yet an established fact. References to arXiv suggest further reading for those interested in the latest findings in this area.

PREREQUISITES
  • Understanding of thermodynamics and entropy
  • Familiarity with cosmological concepts, particularly event horizons

Entropy has an associated energy quantity that has negative pressure (cosmologically... spacetime).

How does one calculate the quantity of this (negative?) energy from the entropy?

Given that an event horizon has maximal entropy, would this produce significant repulsion?

Anyway, I'd like to know how to calculate the quantity of this energy from the quantity of entropy.

Thanks

I do believe there is no such thing as negative energy...
 
Despite your cross-post, I don't think this is quantum related. I understand this to be an area of recent mainstream research but not of accepted fact. You'll find details on the arXiv.
