Does the overturning of Roe v Wade bring the US legal system into further disrepute at a time it is most needed as a bulwark against the Big Lie and its attack on democracy in the States?

Yes,that is the sort of thing(I was looking for the way the different gravity wells joined up) It wouldn't be a problem to add the 3rd spatial dimension (and use 3d glasses) and to run a series of those still frames too get the time dimension, would it?

I just meant to simulate the map of curvature around and extending from the objects in the Solar system. I wasn't interested in actually seeing the objects themselves. Would that be possible?

https://www.newscientist.com/article/2325638-breast-cancer-is-more-likely-to-spread-during-sleep/ "Breast cancer is more likely to spread during sleep" A very interesting finding. A link to a pdf page in Nature in that that I can't seem to copy and paste....

Yes ,I only had in mind what would be practical (and enlightening for me) Is there anywhere that these spacetime graphs have been written down? Some sort of a graphic spacetime depiction of the Solar system at some particular time (say t=01/01/2000 at midnight) If there was then we could make adjacent snapshots (eg t=24 48 ,72 hours later etc ) and run the snapshots like a movie. Accuracy not important ,just maybe as a way of looking at spacetime events in a non local way?

Apparently it was Voltaire who first said "Dans ses écrits, un sage Italien Dit que le mieux est l'ennemi du bien"

@studiot Don't want to derail the thread but we can calculate the weather on our planet over any period if we don't mind inaccurate results. As an aside I was actually kind of amazed to hear on a BBC science documentary recently ,(forgotten the title) that a particular theory could be plugged into BB and give an accurate representation of the universe we are living in That was some forecast!

Trying to flesh out/ fill in gaps in my understanding (using you guys to help me in that) So ,would you have any examples of a "local"Cauchy surface ,defined by causal boundaries and structures that would model a real life system of objects? Could it be a snapshot(time-slice of the 4d manifold) of the Solar system ? Or is that too big a system to be "local"? I am not sure I understood exactly what you were describing by "local surfaces".Did you mean local as in " simultaneous"? (it feels to me that a slice of the manifold where t=constant could be described as "local" in the same way as a unique location in space ,but moving in time would also be "local") Hope my question was coherent.

Would it be possible to make a spacetime model of the complete (ish) Solar system?(say from 2000 to 2010) Would it be visible in the round or would it be in mathematical form only?

Would I be right to say the the curvature of spacetime is an entirely local effect and it would be wrong to make a global picture of spacetime which would hold all the sources of energy-momentum at all the different "events" in the global set? Does one have to calculate the curvature at each event and somehow knit them together in an approximative fashion in order to draw a picture of the spacetime curvature of a system as a whole?

Isn't there a disclaimer signed ahead of any such medical intervention? If the child is under age would this be signed by his legal guardians (his parents)?

Does the problem lie with the expectations and unkind judgements of society moreso than with the individual who is presented with the choice of gender reassignment or not? It feels rather like the situation of "half-casts" who can find themselves not accepted into either one of the cultures they were born into. Is it a weakness to give into the need for social approbation or is it just a realism so that we say we have to give ourselves the best chance in life if we are served with a "bad" hand of cards? Can we pursue both outcomes on parallel tracks and attempt to educate the public why difference is good as also can be "non determinacy" whilst allowing for escape ramps for those who cannot wait for society to catch up with who they think they are? I wonder how we will look back at this question in 50 or 100 years from now and if we can tell ourselves rhen that we have learned anything along the way.

You could start a thread on that in philosophy.

Yes she does.She certainly gets your attention,whereas the chair drains it I feel

Are there any cultures that have no concept (or approximate concept) of god as we might loosely understand it? It might be relevant either way. If the "concept" was everywhere in every culture it would mean it was part of our shared psychological inheritance. If not then that might tell us something very different Does anyone know the answer?

Maybe I am misremembering but didn't I also (iAlso?) have a similar conversation with @iNow in the fairly recent past? Might even have been about effect vs affect.

I got a Covid nose swab last week.Not into my brain ,I think

They might mistake us for God and be worshipping us from afar. the Prince Philip syndrome. Maybe a high quality simulation could have predicted us

Our experience is based on such an infinitesimal section of our own evolutionary development that even that apparent roadblock needs to pass the test of possibly millennia of further development before it can pass its "Sigma test." Agreed it seems likely we will never encounter intelligent alien species in the flesh. If they had themselves survived long enough to discover us they might be well advised to keep their social distance based on present and past evidence.

First this,then I said I will finish up with this thread I started Back to school for me?

No I don't like the dead string sound but I don't like the brand new string sound either. I have had a guitar for over 50 years without understanding the basics of what strings you could use or even what woods might sound better or different. This new guitar was a shock as it is at least twice as light as what I have been using all my life. I would rather it was heavier but I got the next (000) size down as that was all there was in my specs and it turns out fortuitously that it fits my little fingers a lot better and so it is much easier to actually play.

I wood upvote but then I wood have to downvote. Ah feck it I will then.

My name is my (now dead) dog's.I just bought a brand new Fender paramount acoustic and wonder if I need to change the strings.I normally do that when they break or get too rusty but this is a new instrument and I am curious as to how it could sound. Mind you they say it may take a few years for the wood to mature so maybe just wait😀
