### Low Frequency Gravitational Waves ![[Pasted image 20240105131012.png]] ![[Pasted image 20240105131058.png]] Using Pulsar Timing Arrays, Nanograv has been trying to detect these waves. ![[Pasted image 20240105131408.png]] Supermassive blackholes are one of the explanations for why they are seeing these signals. ![[Pasted image 20240105131544.png]] #### Quantum Energy Teleportation Protocol How we could send information without using energy. Pulling energy out of nothing. Quantum energy teleportation is a concept that challenges traditional understandings of energy and space. Initially proposed in 2008 by Masahiro Hotta, a theoretical physicist, the idea was met with skepticism as it suggested extracting energy from a vacuum, something considered impossible under conventional physics. However, Hotta's theory relies on quantum mechanics and the peculiar nature of the quantum vacuum, which is never entirely at rest due to the [[uncertainty]] principle and thus possesses a minimum amount of energy known as zero-point energy. ![[Pasted image 20240105134633.png]] Hotta's protocol doesn't create energy from nothing but teleports it from one location to another using a quantum property called entanglement, where two particles remain connected no matter the distance between them. This is done through a sequence of actions where one party (Alice) injects energy into the vacuum at her location and informs another party (Bob) about the fluctuations in the vacuum. Bob can then use this information to extract an equivalent amount of energy at his location. Recently, two independent experiments have validated Hotta's theory, demonstrating that energy can be teleported over microscopic distances using quantum devices. These findings not only confirm the validity of quantum energy teleportation as a real phenomenon but also open new possibilities for understanding and utilizing energy, quantum mechanics, and possibly the very fabric of space-time itself. ![[Pasted image 20240105134231.png]] https://www.quantamagazine.org/physicists-use-quantum-mechanics-to-pull-energy-out-of-nothing-20230222/ http://www.tuhep.phys.tohoku.ac.jp/~hotta/extended-version-qet-review.pdf http://www.tuhep.phys.tohoku.ac.jp/~hotta/extended-version-qet-review.pdf https://arxiv.org/abs/0803.0348 ### Discoveries from the James Webb Telescope
