Given the speed, there would be a plume of fire in the sky, followed by an eruption of fiery debris led by a shockwave, which would create further debris and kill anything in a relatively small radius. Then, in a larger radius, the debris would rain down causing further damage, and probably fires. Given a city there might follow secondary explosions caused by gas lines and the like.
So, that being said, what happens if 40,000 of them smash the surface of Earth over the course of a few retrograde over major cities, most air bases and nuclear silos?
@BalarkaSen I hope you'll like it, but if you're not enjoying reading it then stop - no-one's paying you to read it :-) Despite the title it contains zero references to The Wasteland.
@JohnRennie found your comments very interesting. agreed dark matter is a great area of investigation/ research & that some major revision connected with GR/ gravity might be forthcoming, also like Verlindes ideas on emergence a lot. but ofc you know the origin of the term "paradigm shift" though right? seems to be "persona non grata" around here at times o_O :(
@vzn The thing is that I'm extremely careful about what I say. The problems I've pointed out are all well known, and I've been careful not to advocate Verlinde's theory because (a) it's purely phenomenological and (b) is doesn't work (yet).
That's why people don't round on me and accuse me of talking bollocks.
hello, is it sufficient to cover algebra and ode/pdes just in a math methods course ? or should I try to take individual courses for these? senior year undergrad here
@Phase It means a reversal of position; in the context, people shifting from respect to disrespect, probably. It is a reference to an interpersonal discussion where somebody switches sides.
That's why I stick to pseudonymity. It isn't particularly strong - a determined person could figure out who I am, if they care to - but it does mean if I manage to trash my reputation I just start over.
@user929304 Well, I have a month left but I don't think anything will come of it, although I have some very rough drafts on QM and gauge theories lying around :P
@Slereah The sudden appearance of a lot of algebraic and differential geometry is quite different from standard QFT
@Phase picture someone standing nearby, hearing something you said and turning round to confront you. That's the image the phrase round on is meant to convey.
@0celo7 the coordinate speed is certainly variable. The four velocity of light is of course undefined anyway :-)
@Phase I rhyme scone with on not own. I rarely eat scones, and when I do it's just with butter so I'm not fussed about what you do with cream and jam as long as it's not illegal/you don't do it in public :-)
Over two years ago now, we made a big shift in how we handle "graduation" - nearly severing the connection between "graduation" and site design. We also talked about removing the "beta" label at some point before sites “graduated” - when sites are clearly past that phase but don't yet qualify for...
@0celo7 I'm not sure where this is going. A proper length of 1m is the same for all observers and most certainly not variable. If you choose some crappy coordinate system you can claim a proper length of 1m isn't 1m in your coordinates (as JD does) but that's a facile claim.
Question (informal)
Is there an empirically verifiable scientific experiment that can empirically confirm that the Lebesgue measure has physical meaning beyond what can be obtained using just the Jordan measure? Specifically, is there a Jordan non-measurable but Lebesgue-measurable subset of ...
@Phase Could we perhaps stay away from using "(un)christian" as a moral descriptor in a joking manner? I get that you bear no ill intent, but it can feel unwelcoming to actually religious people to use it as such, especially given that there's a large variety in the actual moral views of people identifying as Christians.
@0celo7 Well, I don't know much more about it than that some path integrals actually compute that torsion, just something I recalled of the top of my head :D
@0celo7 No, telling another user to "fuck off" is not acceptable, even in jest. We've had this discussion about being mean to each other in an ironic way already several times.
@goodnight I don't take everything at face value but certain jokes you'd make in private with people you know well don't transmit well to a general audience and are thus not appropriate for a public chat such as this.
