    I Questions about paper "How closed is cosmology"

    Finite but >without a boundary<. The term 'bounded' when referring to metric spaces is tantamount to finite. A 3-sphere is boundaryless and bounded. E.g.: https://mathworld.wolfram.com/BoundedSet.html https://en.wikipedia.org/wiki/Bounded_set

    Is the criteria for the present perfect tense in Warriner's textbook inadequate?

    Can you please tell us your background and goals?

    Is the criteria for the present perfect tense in Warriner's textbook inadequate?

    I was at my computer. The book is available from Open Library. As is Fowler's. Conditionals are basically the structures with the 'if' clause. E.g. 'If I were you I'd type "English conditionals" into your search engine'. There's four (main) types for four different shades of hypotheticals...

    B Expansion of the Universe

    See, the first two sentences are fine. But the third doesn't follow - not without dark energy. Without dark energy a universe with any amount of mass in it must always decelerate, much like a ball thrown out of a gravity well must always decelerate even as the gravitational potential...

    Is the criteria for the present perfect tense in Warriner's textbook inadequate?

    Fowler's is a style guide in the form of a dictionary. Is that what you're looking for?

    A Why do novas shine?

    Until just about now I've had the same misconception as you, I think. That the white dwarf is essentially a naked core emitter. Take a look at this paper: https://articles.adsabs.harvard.edu/pdf/2012MmSAI..83..779K There's a brief overview of the process in the introduction. The key takeaways...

    Is the criteria for the present perfect tense in Warriner's textbook inadequate?

    Looking at the book right now. There is a very brief mention of this type of verbs in the very first chapter, on the parts of speech, where it talks about the verb phrase and 'the helping verbs'. Easy to miss and not particularly enlightening. The text seems to be aimed at older children to...

    Collection of Lame Jokes

    It bothers me that the sequence in the name of the game is not the actual sequence. I haven't seen the episode, but can't imagine Sheldon being alright with it either. Rock-paper-scissors-spock-lizard doesn't roll of the tongue as well. So instead rules could easily be adapted to match the...

    B Dark energy might not be constant after all

    It's not that it's 'more correct'. The result is dependent on what one assumes is the correct lower bound for the sum of neutrino masses. If you assume one thing, it's that. If you assume another, it's the other thing. They have to assume something, because it's not known. But there are good...

    I Orientation of the Earth, Sun and Solar System in the Milky Way

    It's not immediately obvious from a 2d picture where the arrows are supposed to point in 3d space, but if you look closely at the markings on the Earth's orbit, you'll notice that it's drawn near to the winter solstice. As such, the northern hemisphere is in fact intended to be facing away from...

    How did ‘concern’ semantically shift to mean ‘commercial enterprise' ?

    That's pretty much rephrased etymonline's entries for the evolution of the verb and the noun. This one's just my gut feeling, yes. It's the usage I'm most familiar with from occasionally translating business documents, but it might be just selection bias. If I were to make an argument, I'd take...

    I Is there an equivalent "redshift" for cosmic rays due to expansion?

    Yes, to both. All such massive particles join the local Hubble flow. The Davis and Lineweaver paper on the tethered galaxy problem includes some analysis of this. It's important to stress that this is not due to some force acting to brake the mass, but as a result of arriving in a region where...

    How did ‘concern’ semantically shift to mean ‘commercial enterprise' ?

    OED is a bit pricey, but one can always use etymonline for a degree of insight. It's free, solid, and iirc uses OED as one of its main sources. As for the meaning shift, here's a rough-and-ready story one could piece together: You start with the verb for using a sieve. This naturally lends...
