Physicists at CUNY ASRC demonstrate a lab analog of Penrose–Zel'dovich energy extraction by using a ring of time-varying resonators to simulate ultrafast rotation, causing electromagnetic waves to extract energy and amplify without any physical spinning parts. The work, published in Nature, creates a versatile platform for studying extreme rotational physics with potential applications in communications and photonics.
The Penrose process, a method to extract rotational energy from black holes, could potentially yield up to 20% of a black hole's mass energy. A recent study explores the idea of extracting energy from charged black holes in anti-de Sitter space, considering the Bañados-Silk-West effect, which could lead to a black hole bomb. However, the study also suggests that in an empty anti-de Sitter universe, energy could be extracted from a charged black hole without leading to a black hole bomb, shedding light on the fundamental nature of space and time.
The Penrose process, a method to extract rotational energy from a black hole, could potentially yield up to 20 percent of the black hole's mass energy. A recent study explores the idea of extracting energy from charged black holes in anti-de Sitter space through particle decay, which could lead to a runaway effect known as a black hole bomb. While these scenarios are purely hypothetical and do not apply to real black holes in our Universe, they provide insights into the fundamental nature of space and time.
The Penrose process, a method to extract rotational energy from black holes, has been a subject of recent theoretical exploration. A study focused on charged black holes in anti-de Sitter space has proposed a way to extract energy through particle decay, potentially leading to a "black hole bomb." However, the study also found that in an empty anti-de Sitter universe, a charged black hole could release energy on its own without causing a black hole bomb. While these concepts are purely hypothetical and do not apply to real black holes in our Universe, they provide insights into the fundamental nature of space and time.
