I have learned that the rate at which the galaxies are receding from each other is accelerating. (Quite the surprise when this was discovered ,I seem to recall) So we have an ongoing acceleration of the recessionary process. Is there any way to quantify this acceleration and so determine whether this acceleration itself is constant or whether it could be slowing down ?(or even speeding up) I think the mathematical term is "jerk" Could the jerk be negative and how could we know?

So ,in practice one would just revert to the Newtonian model? There is just too much gravitational self interaction for the process to be fruitful? Does that change at all if the system reduces to fewer and fewer sources of mass and energy-momentum? Might the gravitational wave simulation that so successfully predicted the wave pattern when those two black holes collided have been done the way you suggested?(they didn't fall back on Newtonian mechanics for that ,surely did they?) I realize that modeling gravitational waves is not the same thing as adding spacetime curvatures.

Some gardening can be dishonest-there is hope for us all

They should have given him a proper job like a gardener when they caught him hiding in the shrubbery. https://gizmodo.com/correction-sean-spicer-wasnt-hiding-in-the-bushes-he-1795117363

Do the multiple sources all have to be calculated individually ? How does the boundary allow one to get to the curvature of the point in space we are interested in? Is there a spacetime distance between that point and the boundary? Do directions come into play ?(is/are there a spatial or tempero-spatial relationship between the sources and the point of which we wish to calculate the curvature?)

I understand that spacetime curvature is mathematically modelled as a local effect. But the effect of gravity is felt at great distances Is it necessary for all the local spacetime curvatures to be summed geometrically for this large gravitational field to be modelled? If so,is there some technique for doing this ? Suppose we are looking at the curvatures produced by the moon and the earth and we pick a point midway between the line that joins their respective centres,how would one calculate the curvature due to the earth and the curvature due to the moon at that point? And how do we add them?

So am I now.I still can't see it :-(

Can't see it either (I see the "achievements" section but it just lists my rank and my rep there) Does that facility only work on a desktop,maybe?

Well if Trump was in custody I might well be tempted to dig a moat around the place and fill it with stingrays and prepared sinkholes -rather than contribute to a GoFundMe account to raise his bail (which would be promoting violence,no?)

I hid in my own garden in the dark after knocking for fun at a neighbour's door. "I know you are there" he called out. We also used to throw stones on the roof of the neighbouring chapel when they sang their piece. We were the hard boys.

Makes sense to me.If done too obviously it would link him to their actions.He would be taking responsibility whereas we know the buck never stopped with him Apparently Trump looks like losing against any of the likely main Dem nominees (I heard that on CNN.So it must be true 😉 )

I wonder who does.

Something was planned.Was assassination planned or just intimidation?** Who was the chief planner ?Trump? Was he the evilest one in the pack? Trump knew Pence's life was in danger it seems to me and did nothing/kept deliberately stum. I can't decide between reckless endangerment (on a huge wicked scale) or the deliberate (if "hopefully " deniable) pursuance of an amoral scheme to be achieved whatever the cost. **I always assumed his plan might have been to play "hostage negotiator" with any of his enemies that were captured by his mob.

I just used it to create web pages If you went to any page and found the "source" of the page it would show up in notepad ,a basic free text editor that came with Windows. If you edited that source code and clicked "save" or "save as" you would find that the page had been updated when viewed in the browser It was best to use notepad because it was so simple but any text editor could work.

So a proton (as a single bodied object of mass) cannot be viewed in the same way as the SS(wrt to its gravitational field)? Its constituent quarks are not in motion in the same way as the planets around the Sun and the cog cannot move around even if it made any sense to want to measure the its gravitational field "up close" ?

Can they impeach him a third time if the Repubs indicate ahead of the procedure that they are receptive to putting in the knife this time? I get the feeling that he may escape prosecution otherwise

Seems like a whole new meaning of "questionable" that doesn't include the speaker as one of those doing the questioning. Have you come across that usage before? Where the speaker says something is "questionable" and the audience has to deduce that the speaker is referring just to other people ,without specifying it? Have to say that referrring to Biden's election as "questionable" certainly makes me deduce that the speaker personally sees something to question about it. We are so used to Trump weaseling (or getting his cronies to do it for him) out of outlandish and disgraceful remarks that it feels like we are entering the post truth area. In the context of American politics to give credence to that stupidity is also disgraceful. Here's the actual quote. It's obvious surely what was being said. Some kind of denigration that makes little sense ,but so what?

Well I have heard that the gravitational effect of any body is independent of any interior structure. Are there examples where this is so -or does my Solar System example show this not to be so? Does the gravitational field exerted by the Solar System "vibrate" ever so slightly as the planets orbit the Sun? Is my understanding of the saying* that the spacetime curvature effect of mass is unaffected by any internal structure maybe a bit "half baked "? *I have read this more than a few times

If we consider the gravitational effect of the Solar system upon its nearest neighbours (or upon the gravitational field immediately outside it) does this change as the SS evolves with time? For example ,as Jupiter moves 180 degrees around the Sun is there a noticeable (or theoretical) effect on the gravitational field as experience by a body outside the SS? I ask this because I have heard that the effect of gravity is not dependent on the interior makeup of a massive body( the Solar System in this instance)

He was put on the ticket in large part because it was realized that he had the electoral beating of Trump and could appeal to the "Rust Belt" Also a very decent,if flawed man

Yes,that one. I mean to take a symbolic case (in addition to practical cases that might actually result in some compensation)

Can they take a class action against the State? Can they also say their civil rights have been violated and light a fire under the Supeme Court?

Is the apparent destruction of phone records by the Secret Services an indication of the likely veracity of Cassidy's testimony? (that would hold up in court as well as public opinion) Esp if they do not refute it on oath Will the US still vote in large enough numbers for a former president who is prosecuted for interfering with the electoral process? The way polls are at present I would say no ,but give the Repubs 2 years in charge of Congress and the Senate and I don't know.

I meant constitute in law It may be obvious to an observer what his game was but unless he can be brought down in the courts ( he should have been convicted in the impeachment trial) or by force of public opinion (and opinion within the Republican party) that is fairly academic . If he were to win a second term ,I cannot imagine the repercussions.

Does the mere fact of urging the crowd to march to the Capitol constitute interference in elections? I know his interference in the Georgia count was clothed in the pretense of there being electoral fraud but should this call to actually march on the Capitol be an even clearer case of interfering in the election?(never mind whether or not he-indirectly? - incited them to murder Pence) What I mean of course is could he be successfully prosecuted over it?
