3.6.2Black hole and gray hole: mitigation and countermeasures In[42], theIDSis able to detect black and gray hole attacks thanks to a trusted supervisor that monitors packet loss. The system raises an alarm when a node is failing to forward a number of packets superior to a threshold repre...
and space and time cease to exist. when this happens, the laws of physics break down because it is not really humanly possible to conceive of anything with zero volume and infinite density. 2 there is no tunnel at the center of a black hole www.ifans.com as we said earlier, contrary ...
Extreme scenarios of AI focus on what is logically possible rather than what is physically possible. What does physics have to say about AI risk?
How our treatment leads to a unitary description of the black hole evolution laws is recapitulated in Section 7. Some of the problems still left wide open are mentioned in Section 8, and we phrase our conclusions in Section 9. 2. The Pure, Time Independent State Consider the metric of a ...
Several theories have been proposed to describe the formation of black hole seeds in the early Universe and to explain the emergence of very massive black holes observed in the first thousand million years after the Big Bang1–3. Models consider dif
报告摘要:Observations reveal the presence of a massive black hole (MBH) at the center of the Milky Way and other nearby galaxies. If these MBHs are massive binary black holes (MBBHs), they may be potential nanohertz gravitational wave (GW) sources for pulsar timing array (PTA). Several pu...
Exact solutions of both angular and radial parts of the covariant Klein-Gordon equation in this background are obtained, and are given in terms of the confluent Heun functions. The role of the presence of the cosmic string in these solutions is showed up. From the radial solution, we obtain...
