The 'Two State' Solution Is Insane

The European Space Agency’s Solar Orbiter has observed the incredible behavior in the Sun’s lower atmosphere like never before. The Sun's corona is an ever-changing landscape with a range of fascinating features‚ from &;quot;moss&;quot; to &;quot;rain&;quot;. The new footage is providing a front seat to the currently active Sun.In previous videos of the Sun‚ we have seen spectacular eruptions release huge quantities of particles out into the Solar System. In September last year‚ Solar Orbiter spotted a more modest eruption – although it was still taller than our whole planet – as well as coronal moss‚ coronal rain‚ and spicules all in amazing detail‚ which has just been released.                         So‚ what are we looking at in this video&;#63;On the solar horizon we can see spicules‚ spires of plasma that reach up from the chromosphere into the solar corona above. They extend up to 10‚000 kilometers (6‚200 miles) into the higher levels of the solar atmosphere. We can also see coronal &;quot;moss&;quot;‚ lace-like patterns of plasma found at the base of coronal loops‚ the arch-like structures seen extending well above the surface of the Sun.Those loops create another effect: coronal rain. The loops are very bright because they are very hot‚ around 1 million °C. Some of the plasma cools and‚ thanks to gravity‚ comes back down in darker high-density clumps known as &;quot;rain&;quot;. These clumps are still hot but less scorching at probably less than 10‚000 °C (18‚000 °F). They are easier to see as they are much darker than the intensely hot coronal loops. This is the Sun in extreme ultraviolet.Solar Orbiter took the video on September 27‚ 2023. Just a few days later‚ on October 7‚ it was at its closest distance from the Sun: 43 million kilometers (26.7 million miles). That’s less than one-third of the Earth-Sun distance. On the same day the video was taken‚ NASA’s Parker Solar Probe was just 7.26 million kilometers (4.51 million miles) from the Sun‚ so the space agencies teamed up. Parker measures the particles and magnetic field in the Sun's corona and the solar wind‚ so Solar Orbiter observed the region from where the solar wind came to flow past Parker. Together‚ the spacecrafts are providing important insights into the Sun and how it works.

We live in (or at least‚ perceive‚ with various branches of string theory including up to 26 dimensions) a universe with three dimensions (plus time)‚ and there are reasons to suspect why we find ourselves in a 3D world. Scientists and mathematicians have suggested universes with more than three dimensions would be unpredictable and unstable &;quot;dead worlds&;quot; devoid of all life and observers. The three body problem is unpredictable in a 3D world‚ but even a two body problem – describing and predicting the orbit of two bodies – becomes too chaotic in higher dimensions‚ and no stable orbits are possible. &;quot;This means that such a world cannot contain any objects that are stable over time‚&;quot; one paper on the topic explains‚ &;quot;and thus probably cannot contain stable observers&;quot;.&;quot;In a space with more than three dimensions‚ there can be no traditional atoms and perhaps no stable structures‚&;quot; the paper adds.As such‚ we should not be surprised that we find ourselves in a 3D (plus time) universe – you can only live in universes where life is possible. There are suggestions that life could not take place in a 2D (plus time) universe‚ meanwhile‚ because of insufficient complexity. The main argument‚ which would make 2D universes a non-starter‚ is that two-dimensional universes would not allow for gravity‚ making the complex mix required for life impossible.But that may not be the case‚ according to physicist James Scargill. In a 2020 paper‚ Scargill showed that scalar gravitational fields could exist in two dimensions.     &;quot;I have presented a purely scalar theory of gravity which allows stable orbits around point sources‚ and has a not-obviously-fatal (though unusual) cosmology; it could potentially be improved by making the whole metric dynamical‚&;quot; Scargill writes in the paper. &;quot;One could also imagine a brane-world scenario in which the massless graviton is not localized to the brane‚ thus allowing two-dimensional life to enjoy fully four-dimensional gravity.&;quot;Gravity and stable orbits are not the only requirements for life – or‚ more important when you are using anthropic reasoning to explain why we are in a 3D universe‚ for observers to exist. For instance‚ you could not have a digestive tract in an animal (at least not the kind we are used to) as it would split the organism in two. Scargill went on to look at whether a 2D universe (again‚ plus time) would be sufficiently complex to allow for complex life. In the paper‚ he looked at biological networks and created planar graphs which &;quot;seem to exhibit many of the properties which have been conjectured to be important for complex brains.&;quot; This‚ he writes‚ is suggestive that complex brains could exist in two dimensions‚ though more work would be needed to compare the planar graphs to real-world neural networks.&;quot;In particular‚ they are approximately ‘small-world‚’&;quot; he added‚ &;quot;they have a hierarchical and modular construction‚ and they show evidence of the stretching (in parameter space) of a critical point into a finite critical region for certain stochastic processes.&;quot;This is‚ of course‚ highly hypothetical‚ and more of a thought exercise than saying life in 2D universes is real. But it puts a bit of a constraint on arguments that we experience a 3D world because it is the only type that could sustain life‚ because – perhaps – life in 2D could be possible as well.The paper is published in Physical Research Review.

Check out the latest futuristic offering from the Defense Advanced Research Projects Agency‚ otherwise known as DARPA. From the people who brought you hypersonic air-breathing weapons‚ submarine-detecting shrimp‚ and robot jazz musicians comes a massive manta ray-inspired uncrewed submarine. Constructed by Northrop Grumman‚ the prototype just completed its first in-water test.The sub has been devised to carry large payloads over long distances underwater‚ with no humans onboard for support. During deployment‚ it can spend periods of time in “hibernation”‚ anchored to the seabed to conserve energy.When the project was announced in 2022‚ Northrop Grumman wrote that their design would be in service of DARPA’s vision to create “strategic surprise.” We think they can safely say they’ve achieved that goal.DARPA recently announced that a full-scale test of the prototype uncrewed underwater vehicle (UUV) had taken place off the coast of Southern California in February and March of this year.“Our successful‚ full-scale Manta Ray testing validates the vehicle’s readiness to advance toward real-world operations after being rapidly assembled in the field from modular subsections‚” said Dr Kyle Woerner‚ DARPA program manager for Manta Ray‚ in a statement. “The combination of cross-country modular transportation‚ in-field assembly‚ and subsequent deployment demonstrates a first-of-kind capability for an extra-large UUV.”That “extra-large” is about as detailed as we can get right now. New Atlas notes that DARPA and Northrop Grumman have so far kept most of the technical specifications of the craft to themselves‚ speculating that images released online appear to show shrouded propulsors‚ an antenna‚ water inlets‚ and possibly maneuvering thrusters.From the images we can get some sense of scale and see that its smooth contours really do resemble its namesake animal - and maybe the odd sci-fi creation too.  IFLScience is not responsible for content shared from external sites.There are hundreds of different species of manta rays found in waters across the globe. They’re sociable and intelligent creatures‚ with numerous reports of them seeming to interact with divers and snorkelers. But it was the manta rays’ graceful locomotion that really inspired the engineers behind the new UUV‚ continuing a long tradition of bioinspired design.“Once deployed‚ the vehicle uses efficient‚ buoyancy-driven gliding to move through the water‚” said Woerner.Dr Kyle Woerner (right) chats with a member of the Northrop Grumman team on top of Manta Ray.Image credit: DARPAAnother key advantage of the Manta Ray UUV‚ as highlighted both by DARPA and Northrop Grumman‚ is that it can be shipped in pieces and rapidly reassembled on-site. This is how the prototype was transported from the build location in Maryland to the opposite side of the country and could also be handy in the field.“Shipping the vehicle directly to its intended area of operation conserves energy that the vehicle would otherwise expend during transit‚” Woerner explained. DARPA says it’s currently working with the US Navy on the next steps for this technology – we’ll have to wait to find out when Manta Ray might be taking to the water for real.
