Could dark energy be emitted from stars?Dark matter could. Thorough searches to find it have so far drawn a blank.
Given that the best fit for dark energy is the cosmological constant, and that other alternatives to the cosmological constant (quintessence and phantim energy) are also part of Einstein’s equation for gravity, dark energy isn’t transmitted at all.
Dark energy is well understood. Dark matter is not.
Dark energy is zero point energy ?
Um. It’s at least 15 years since I’ve heard the term “zero point energy”. I’ve forgotten what it means.
Looks it up, ah, the Casimir effect.
> Dark energy is zero point energy ?
To tell the truth I don’t know. Dark energy is so tied up in general relativity, and zero point energy is so tied up in quantum mechanics that I don’t know how they relate to one another.
Dark energy appears as the constant Λ in the following equation from GR, or as an alternative term where it isn’t a constant.
