The curved spacetime Effective Field Theory (cEFT) is a much needed extension of the ideas of
the Effective Field Theory to the case in which gravity, described by the spacetime curvature, cannot
be ignored. After a gentle introduction of the mathematical techniques needed for the task at hand, the
presentation will focus on two particular applications of cEFT, i.e., vacuum stability in the presence of
self-induced gravitational field and influence of spacetime curvature on properties of boson and dark
fermion stars. In broad terms, the former is a new incarnation of the very old question, namely why
do we exist? This question is tackled by investigating cosmological implications of the Higgs vacuum
stability. Meanwhile, the latter addresses, among other things, a problem of lack of a direct detection
of dark matter particles and alternative sources of the detected gravitational wave signatures.
