Spaceflight 🚀🔭 #PlanetNine is likely to be the fifth largest 📏 #planet 🪐 in the #SolarSystem 🌌 https://www.independent.co.uk/space/nine-planet-solar-system-b2500389.html
An advanced #extraterrestrial civilization could potentially detect 🔭 signs of life on Earth. But the #scale of the #universe 🌌 is incredibly vast. Even at the speed of light, signals 📶 from #Earth 🌏 have only reached a very small portion of our #galaxy. https://newspaceeconomy.ca/2023/07/15/can-extraterrestrial-life-detect-us/
Any civilisation 👽 reading our messages could be billions of years ahead of humans. “If so they will be vastly more powerful and may not see us as any more valuable than we see bacteria” https://www.theguardian.com/science/2016/sep/23/stephen-hawking-warns-against-seeking-out-aliens-in-new-film
👽 “Look at the mess we made when #Covid hit. We’d be like headless chickens 🐓. We cannot afford to be ill-prepared, #scientifically, #socially, and #politically rudderless, for an event that could happen at any time and which we cannot afford to mismanage.” https://www.theguardian.com/science/2022/dec/29/if-aliens-contact-humanity-who-decides-what-we-do-next
