There&#x27;s also a short video on this: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=rENyyRwxpHo">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=rENyyRwxpHo</a><p>Plus there&#x27;s that scene from Stargate Universe:<p>- Are those stars?<p>- No, those are galaxies.

This will sound stupid... but as we find out that the universe is bigger and bigger and there are more clusters, galaxies, stars, and planets then we have imagined before (Laniakea have 100,000–150,000 galaxies and the Milky Way _alone_ have 100–400 billion stars)<p>so does that increase or lower the chance that there is _any_ kind of life outside there? Maybe not carbon-based life but any kind. Next question would be I guess that what is &quot;life&quot;<p>Fascinating stuff nonetheless

The next time you address a package to someone, err on the side of caution and append &quot;Earth, Solar System, Local Interstellar Cloud, Local Bubble, Gould Belt, Orion Arm, Milky Way, Milky Way Subgroup, Local Group, Local Sheet, Virgo Supercluster, Laniakea Supercluster, KBC Void, Observable Universe, Universe&quot;, to help the package carrier disambiguate.

We need Faster Than Light (FTL) travel otherwise we’re stuck here on Earth. I believe that there are other beings out there, but the vast distances prevent contact. If they haven’t discovered exotic means of travel like wormholes, hyperspace, warp drives, or something else, then we’re doomed to remain separated :-(<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Faster-than-light" rel="nofollow noreferrer">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Faster-than-light</a>

For the neverending stream of talk about VR this, metaverse that, and WebGPU there, there should really be a KISS 3D format for the web so we can view things like this properly. Like Markdown simple. No shaders or animation or anything like that. Default lighting only.<p>It feels sad to look at a 2D image of the most 3D of all things.

Start with an analogy: We&#x27;ve never seen a car before but find one, learn how to drive it, and are amazed, and ask &quot;How does this amazing thing work?&quot;. We study the rubber in the tires, the disk brakes, the air conditioning, the universal joints, differential, the transmission, the pistons.<p>Then we see the box that has the computer for controlling the fuel injection and ignition and start to take it apart to see how it works when one of us says:<p>&quot;Stop. In broad terms, I can tell you how it works: It does what it needs to do so that the car can work. But by now we have gone so deep into how this car works that it is time to ask<p>What is the purpose of this car?&quot;<p>The universe as it seems from current astronomy, ..., is one huge and intricate construction. Sorry, but tough to believe that all of this has no purpose.<p>Ah, two possibilities:<p>(1) We really are the <i>center</i> of the universe and the only life.<p>There is a lot less to the universe than what seems from current astronomy. In particular, objects we can never reach due to the speed of light limit are just fake, something like a painted screen.<p>(2) We have not found it yet, but there is a way to violate the speed of light. The whole universe is ours for the taking once we see how to exceed the speed of light. There is a <i>game</i>: For the laws of physics, how long will it take for life to develop to understand these laws and, in particular, how to exceed the speed of light?<p>For either of (1) or (2), maybe we should start a new subject, <i>super cosmology</i>, that assumes that the universe has a purpose. We look for that purpose and, for each discovery we make, e.g., dark matter, quantum mechanics, black holes, quasars, gravitational waves, ..., ask what its role is in the purpose of the universe.

Followed some links around, and this was interesting <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Abell_3266" rel="nofollow noreferrer">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Abell_3266</a> !<p>&quot;The Department of Physics at the University of Maryland, Baltimore County discovered that a large mass of gas is hurtling through the cluster at a speed of 750 km&#x2F;s (466 miles&#x2F;second). The mass is billions of solar masses, approximately 3 million light-years in diameter and is the largest of its kind discovered as of June 2006.&quot;

Came here to learn about some new HPC supercluster... Oh well.
