متن کاملTesting Weak-Field Gravity
One of the most important problems in science today is the origin of \dark matter". Much of our understanding of the history and present state of the universe depends upon conjectures about the nature of dark matter. In some sense, our knowledge rests upon a \house of cards" which won't be buttressed until progress is made in identifying what dark matter represents. Most research today is found...
متن کاملWeak Gravity Conjecture
We investigate whether the eternal chaotic inflation can be achieved when the weak gravity conjecture is taken into account. We show that even the assisted chaotic inflation with potential λφ or mφ can not be eternal. The effective field theory description for the inflaton field breaks down before inflation reaches the eternal regime. We also find that the total number of e-folds is still bound...
متن کاملAttractors at weak gravity
We study the attractor mechanism in low energy effective D = 4, N = 2 Yang-Mills theory weakly coupled to gravity, obtained from the effective action of type IIB string theory compactified on a Calabi-Yau manifold. Using special Kähler geometry, the general form of the leading gravitational correction is derived, and from this the attractor equations in the weak gravity limit. The effective New...
متن کاملThe gravitational interaction of light: from weak to strong fields
An explanation is proposed for the fact that pp–waves superpose linearly when they propagate parallely, while they interact nonlinearly, scatter and form singularities or Cauchy horizons if they are antiparallel. Parallel pp–waves do interact, but a generalized gravitoelectric force is exactly cancelled by a gravitomagnetic force. In an analogy, the interaction of light beams in linearized gene...
