WebG is Newton’s constant, μ is the cosmic-string tension (i.e., energy per unit length), k labels the harmonic modes of cosmic-string loops, and P k ¼ Γ=kq=ζðqÞ is the averaged GW power spectrum. We assume that P k is dominated by cusps propagating along cosmic-string loops (q ¼ 4=3). P k is normalized such that the total emitted power ... WebThese strings may weave throughout the entire universe, thinner than an atom and under immense pressure. Naturally, this means they'd pack quite a gravitational pull on anything that passes near them, enabling objects …

WebJun 28, 2024 · A cosmic string is a kind of structure that has been discussed in theoretical physics for quite a while. I think most attempts to think about quantum gravity allow such things, so I don't think a cosmic string would necessarily distinguish among quantum gravity theories. In that sense it would not necessarily support string theory over other ... WebFeb 3, 2009 · Cosmic Strings and Cosmic Superstrings Mairi Sakellariadou In these lectures, I review the current status of cosmic strings and cosmic superstrings. I first discuss topological defects in the context of Grand Unified Theories, focusing in particular in cosmic strings arising as gauge theory solitons. cheap pool deals
