Editing Cosmological constant (section)

=== Failure to detect dark energy ===
An attempt to directly observe and relate quanta or fields like the [[chameleon particle]] or the [[symmetron]] theory to dark energy, in a laboratory setting, failed to detect a new force.<ref>{{cite journal |last1=Sabulsky |first1=D.

It is also possible that the difficulty in detecting dark energy is due to the fact that the cosmological constant describes an existing, known interaction (e.g. electromagnetic field).<ref>{{Cite journal |last=Ogonowski |first=Piotr |date=2023-01-09 |title=Proposed method of combining continuum mechanics with Einstein Field Equations |url=https://www.worldscientific.com/doi/10.1142/S0218271823500104 |journal=International Journal of Modern Physics D |volume=32 |issue=3 |language=en |pages=2350010–2350024 |doi=10.1142/S0218271823500104 |issn=0218-2718|arxiv=2212.13113 |bibcode=2023IJMPD..3250010O |s2cid=254778036 }}</ref>
