To l...I went to see Interstellar at our local Imax. To lift your words out of context (as review blurbs often do), it was "simply awful", a real waste of my time and money.<br /><br />I know about suspension of disbelief in order to enjoy certain fictions, but I couldn't keep it going. To spend so much effort to get the black hole physics correct (or at least credible) and then to disregard basic mechanical engineering lost it for me. You don't just spin up and spin down a massive circular spaceship with a few puffs from thrusters - it's weightless but still has a large inertia. And the part toward the end when parts of the spaceship were destroyed - those stresses would have torn the structure apart.<br /><br />I went to see current state of the art special efforts, which I got. But aside from that everything was what I despise about what's coming out of Hollywood these days. (Not surprising as I'm the wrong demographic with the wrong tastes to be in their target audience.) The elevation of special effects above all else. Self-indulgence and excessive length. Incoherent character development. Cliched acting.<br /><br />The Michael Caine character quoting Dylan Thomas once was moving. Twice was silly. A third time was just twee.<br /><br />It is possible, even in today's movie market, to make an excellent science movie. Moon, for example. But I'm almost always let down.<br /><br />One of my sons encouraged me to see Interstellar, texting me that it's 'spectacular'. After I wasted my time I texted back that it's 'spectacularly awful'.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8587336.post-64457397585061970982014-12-13T10:50:28.887-08:002014-12-13T10:50:28.887-08:00The new Heinlein biography from Tor is in two part...The new Heinlein biography from Tor is in two parts.

If our civilization collapses, we would want a recovery within a few thousand years. In which case global civilization II is SOL. In millions of years, humans will have evolved or gone extinct. We have no idea if another intelligent species will replace us. Only then can they use such fossil fuels. But bear in mind that coal is mostly Carboniferous, a once in a planetary lifetime event so far. So coal, which powered much of the industrial revolution is unlikely to ever be replaced with easily accessible deposits.<br /><br />The good news is that trees will be abundant, so wood and charcoal can be used. But the supplies will always be limited as England discovered as it removed its forests for charcoal burning.<br /><br />Even if AGW and health effects of fossil fuels were not an issue, it is our consumption of them at rates far exceeding replenishment that is a problem for a sustainable global civilization. They can only be a bridge fuel supply until we can use inexhaustible ones.Alex Tolleyhttps://www.blogger.com/profile/01556422553154817988noreply@blogger.comtag:blogger.com,1999:blog-8587336.post-91585070777883381242014-12-13T08:24:22.526-08:002014-12-13T08:24:22.526-08:00With respect to John M. Smart's "mental r...With respect to John M. Smart's "mental rewrite", I found myself performing that little dance in my own head as I was watching the movie. In <i>my</i> mental version of "Interstellar",<br /><br />The blight was a purposefully designed doomsday weapon deployed by a radicalized environmental/anti-human faction and Earth's societies had simply retreated into a "popular", nihilistic philosophy in the wake of the wars that were mentioned (probably started by the group that designed the life-destroying disease). We had seen a little of this attitude in the wake of WWI.<br /><br />Humanity may have had indeed destroyed itself.<br /><br />The multi-dimensional beings may indeed exist at some point in the future, and might be trying to affect an "Omega Point" scenario in which they, as powerful demigods in their own right, attempt to recreate various pasts for their own purposes. I imagined them re-creating, in a very literal Omega Point sense, humanity but giving us a little help to allow us to live. Our heroes may or may have not existed in our "timeline", but may have been injected by the demigods to help recreate humanity and give us a future. <i>No backwards time travel necessary!</i> All of it was part of the recreation (in a substrate that gives us "souls" and honest life).Nicole Tedescohttps://www.blogger.com/profile/05021670877874507957noreply@blogger.comtag:blogger.com,1999:blog-8587336.post-41988735315356413312014-12-13T07:19:28.255-08:002014-12-13T07:19:28.255-08:00Daniel Duffy,

The guy actually lived in my home town for several years, in a ritzy-rich neighborhood called the Broadmore. My 5th grade teacher, who introduced me to his books, told me that he was essentially driven out of the neighborhood by a coalition of husbands who had grown tired of his philandering. Given the subjects of some of his books (including some of his best) this shouldn't be a big surprise. But I wonder if it would be missed opportunities for interstellar travel he would be shedding tears for in his afterlife...<br /><br />Paul451,<br />Sorry I haven't had a chance to answer your question since before Dr. Brin's last cry of "onward!" I had unexpected company from out of hemisphere show up at my door. You had asked about oil formation processes and how common they would be. Since this isn't an area I know a lot about (and Googling isn't always reliable), I asked the geology teacher 2 doors down about it. He went on at some length, so I think he was glad to get a real geology question for a change. Anyway, what I got from that conversation was that oil formation is really very common. It mostly comes from micro-organisms (not so much from dinosaurs) and commonly happens in fluvial and lacustrine deposits (rivers, lakes, swamps & bogs) as well as shallow ocean contexts. There are many places all over the world where oil is forming as we speak, the Amazon Basin being a prime example.<br /><br />However, formation isn't the whole story. Oil deposits in sedimentary rocks can be dispersed by a rising water table, and frequent changes to a water table can be expected over the millions of years it takes for microflora to turn into fossil fuel. What you need is a context that would create less porous rocks to trap the oil in place - what they call a capstone. Volcanic eruption can do this easily, so anywhere you have volcanoes in tropical areas, like Indonesia or the Andes, you have some solid potential for creating extractable oil deposits. Likewise metamorphic processes, which is why there is so much oil on continental shelves, and around folded mountains.<br /><br />As to oil on other worlds, it is entirely plausible that we will one day find oil on Mars, and any planet similar enough to our own that could harbor carbon-based life would be highly likely to have oil as well. Perhaps my concerns about timing are not very meaningful, then.<br /><br />Happy cogitation <br /><br />Paul Shen-Brownnoreply@blogger.comtag:blogger.com,1999:blog-8587336.post-8108752131212878222014-12-12T16:14:38.483-08:002014-12-12T16:14:38.483-08:00Possibly interesting, but all of that content isn&...Possibly interesting, but all of that content isn't available where I live (Canada).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8587336.post-16638324783678613032014-12-11T14:01:00.275-08:002014-12-11T14:01:00.275-08:00Hey I did my best.
