In case you missed the news, the first images came in from the James Webb telescope, a nail-biting feat of engineering. Launched on Dec. 25, 2021, on an Ariane-5 rocket from Europe’s Spaceport in French Guiana, South America, the James Webb Space Telescope completed a complex deployment sequence in space, where its mirrors were aligned, and its instruments were calibrated to the space environment. Now, the first images of our universe that has ever been taken. As astrophysicist Jane Rigby marveled about SMACS 0723, "We took that image before breakfast." In 12.5 hours, NASA changed the way we see the universe. If Hubble images were mind-blowing— the Webb images are transcendent. “Today, we present humanity with a groundbreaking new view of the cosmos from the James Webb Space Telescope – a view the world has never seen before,” said NASA Administrator Bill Nelson. “These images, including the deepest infrared view of our universe that has ever been taken and show us how Webb will help to uncover the answers to questions we don’t even yet know to ask; questions that … [Read more...] about James Webb Space Telescope Unfolds the Universe
Space Craziness with Astronaut Chris Hadfield
I am going to miss the amazing videos from Commander Chris Hadfield, the Canadian astronaut who streamed his odd missives from the International Space Station with an earthiness that was both hilarious and informative. Many of his videos are practical demonstrations about the reality of our physical bodies meeting a gravity-free environment like space. Watching these videos will change your perspective of gravity. Hadfield's experiments create a visceral understanding of the fact that everything we do from moving to eating and everything we experience around us is in a complex dance with gravity. Our very existence depends on gravity. What better way to show it than to wring out a wash cloth in space? Hadfield demonstrates crying in space: Chris carries out student experiment by wringing out a wash cloth in space then waxes philosphical: Chris talks about "space vision" and testing eyeballs in space: Hadfield talks to William Shatner AKA Captain James T. Kirk: … [Read more...] about Space Craziness with Astronaut Chris Hadfield
Simulation Theory: Is God a Computer Programmer?
Computers and the Internet have changed the way we conceive of the universe. Complex systems, algorithms, programming, pixels, data-mining, viral propagation and virtual realities are new additions to the vocabulary of modern thought. These concepts have migrated to books, films and TV and to the single most powerful way we create models of our universe, scientific hypothesis. Welcome to The Simulation Theory, because without computers, this theory couldn't exist. If you've seen The Matrix, you already know a lot about this theory. Neo is trapped in an extremely compelling artificial reality. He wakes up in the real world which is nowhere near as seductive or addictive as the illusory Matrix. The theory was first proposed by the futurist Hans Moravec (Robotics Institute of Carnegie Mellon University) and was elaborated on in a paper by Professor Nick Bostrom (Oxford University) who theorized we could all be living in a simulation. But Bostrom doesn't stop there. He goes on to say it is likely we are already in a simulation being run by a “post human” … [Read more...] about Simulation Theory: Is God a Computer Programmer?
