UFOs are now known as UAPs, which stands for “unidentified anomalous phenomena.” These phenomena are increasingly popping up in headlines as technology advances, but for some reason scientists are still reluctant to research them. Let’s take a look at some recent UAP sightings and why we need to invest more into UAP research. 👕T-shirts, mugs, posters and more: ➜ https://sabines-store.dashery.com/ 💌 Support me on Donorbox ➜ https://donorbox.org/swtg 👉 Transcript with links to references on Patreon ➜ https://www.patreon.com/Sabine 📝 Transcripts and written news on Substack ➜ https://sciencewtg.substack.com/ 📩 Free weekly science newsletter ➜ https://sabinehossenfelder.com/newsletter/ 👂 Audio only podcast ➜ https://open.spotify.com/show/0MkNfXlKnMPEUMEeKQYmYC 🔗 Join this channel to get access to perks ➜ https://www.youtube.com/channel/UC1yNl2E66ZzKApQdRuTQ4tw/join 📚 Buy my book ➜ https://amzn.to/3HSAWJW #science #sciencenews #uap #aliens Source: © Sabine Hossenfelder, hosted on © YouTube |

Also on Amazon: https://noviumdesign.shop/jTAp1f The search for life on another planet is one of the most exciting things in astrophysics. As humanity has searched the universe for signs of life, we’ve found a surprising number of clues suggesting that alien life might exist on multiple other planets. Let’s take a look at how this search is developing and what “signs of life” really are. 👕T-shirts, mugs, posters and more: ➜ https://sabines-store.dashery.com/ 💌 Support me on Donorbox ➜ https://donorbox.org/swtg 👉 Transcript with links to references on Patreon ➜ https://www.patreon.com/Sabine 📝 Transcripts and written news on Substack ➜ https://sciencewtg.substack.com/ 📩 Free weekly science newsletter ➜ https://sabinehossenfelder.com/newsletter/ 👂 Audio only podcast ➜ https://open.spotify.com/show/0MkNfXlKnMPEUMEeKQYmYC 🔗 Join this channel to get access to perks ➜ https://www.youtube.com/channel/UC1yNl2E66ZzKApQdRuTQ4tw/join 📚 Buy my book ➜ https://amzn.to/3HSAWJW #sciencenews #science #astronomy #space Scientists have found tentative evidence for life in another solar system, with recent James Webb Space Telescope data on exoplanet K2-18b sparking headlines.

We'll discuss the concept of exoplanetary biosignatures and the high standard of proof required for official acceptance before we can definitively say we've found signs of life on habitable planets.

Use code Sabine at the link below and get 60% off annual plans: https://incogni.com/sabine Recently, Finnish researchers made waves by announcing progress in the field of wireless energy transfer using a combination of sound waves, laser systems, and electromagnetic radiation. While they haven’t miraculously figured out how to beam energy long distances with perfect efficiency, their research – and other projects in the same field – have made some significant progress in wirelessly transmitting energy.

 | These physicists think we're totally wrong about entropy 🌏 Get Exclusive NordVPN 2Y deal + 4 months extra here → https://nordvpn.com/sabine It’s risk-free with Nord’s 30-day money-back guarantee! ✌️ The Boltzmann brain hypothesis states that, between the Big Bang occurring and a fully-formed brain suddenly popping into existence in space, the brain spontaneously appearing is more probable. In a recent paper, a group of physicists have compared the second law of thermodynamics and the Boltzmann brain hypothesis – after analyzing both, they concluded that both are equally legitimate theories of physics. Let’s take a look at what this means and if they might be right.

This provocative claim not only challenges established theoretical physics but also raises profound questions about our understanding of reality and consciousness. The paper suggests that, from a philosophical perspective, our perceived universe might be an illusion, and we could be mere brains in an otherwise empty cosmos, prompting a critical look at logic and science.

 | These Physicists Say They Found The Origin Of Reality Take back your personal data with Incogni! Use code Sabine at the link below and get 60% off annual plans: https://incogni.com/sabine One of the most perplexing questions in the foundations of physics is how our shared sense of reality emerges out of quantum mechanics. This is because in quantum mechanics, it seems, different observers can arrive at different conclusions about what is real and what not. A group of physicists now used an approach called “Quantum Darwinism” to solve this tricky problem. At least they say they solved it. I am not so sure. Let’s have a look.

It features a presentation of a scientific paper on the "Metrological approach to the emergence of classical objectivity," suggesting a potential solution to a long-standing problem in quantum mechanics. We explore how the "observer effect" and individual "consciousness" play a crucial role in shaping our understanding of "reality does not exist" within the realm of "quantum physics explained." This deep dive connects the fundamental principles of "quantum mechanics" with profound questions in "philosophy." Source: © Sabine Hossenfelder, hosted on © YouTube |

Friction affects almost everything around us. It makes cars drive, our muscles contract, and even helps us walk. But in terms of technology, friction often means wasted energy — that’s why material scientists are always looking for ways to minimize it. In a recent paper, researchers say that they’ve found a material that can reduce friction to almost zero. Let’s take a look.

Stay fully informed on events around the world with Ground News. Using our observations and predictions based off of Einstein’s theory of general relativity, physicists are pretty sure that there’s a supermassive black hole at the center of the Milky Way.
