Would it even be possible to figure out how to cancel all the different motions one was subject to, so as to be "motionless" in space? And even then, all the atoms that compose 'you' and whatever you're wearing, would be in motion...
Wow! Double heavy!!
Has there ever been an electron, a neutron, or a photon that 'stood still'?
This is so heavy that I've just broken all my scales!!
There is one person that posts here that is qualified to answer this heavy stuff....at least they think they are qualified....qualification depends on how many articles they can link and names they can drop.
>Has there ever been an electron, a neutron, or a photon that 'stood still'?
What do you mean by 'stood still'?
If you mean completely motionless, then according to quantum mechanics the answer is NO. If it were completely motionless then its momentum could be exactly determined (it would be 0), at the same time, its position could be determined exactly as well. This would violate the uncertainty principle. (see also zero point energy).
Relativistically speaking, if you were in a frame of reference travelling at exactly the same speed as the particle and in exactly the same direction, then the particle would **appear** to be standing still, although it would not actually be completely motionless.
I appreciate you 'trying' to be all scientific and such, but without a YouTube citation and a couple of pithy quotations, I'm afraid you're not meeting RfM's minimum standards.
One immediate problem a space-faring Race dedicated to "making something big stand still" would encounter is making themselves stay in one place long enough to work on their project.
Making your sun/planet combo "stand still" would likely make distant observers go nuts trying to figure out why 'you' disappeared from sight so quickly...
I can't believe R.A. Heinlein's oeuvre doesn't include a juvenile novel, "The Man Who Stood Still."
The US space programs have added immensely to US technology and hence GDP. Among the many are satellites and wireless communications systems, bluetooth communications systems, materials and thermonuclear coolers for semiconductor production, programmable appliances, high temperature lubricants for industrial purposes, all sorts of medical technologies and devices, new textiles and clothing for extreme temperatures and extreme industrial conditions, and things like carbon nanotubes whose potential is enormous. The space programs were one of the things that catapulted the US economy to the technological and industrial frontier.
The payoff from this sort of public-private investment--for such it always is--is many times greater than the cost.
Next you'll point to people on welfare and declare that the educational system is a waste of time, money, and talent that could be better invested in keeping front lawns safe from ruminants and small children.

Many of those things would probably have happened anyway, but some would almost certainly have not. Moreover many of those things, if they had happened, would have occurred in other countries, enabling those countries rather than the US to achieve the concomitant scientific and technological pre-eminence.
You know what else wouldn't have been born in the United States? Search engines allowing you to check your factual assertions before removing all doubt, if you know what I mean.
If exploration (and eventually settlement,) is not worth it, then maybe Columbus, the Pilgrims, etc. should have turned around and gone home. Exploration and settlement are what our species does. Mars will be our second home one day. Eventually it will be given a breathable atmosphere. The moon will be home to some as well.
NASA's budget is a drop in the bucket when you look at the big picture. This is a long-term play.
One of the pleasures of watching the TV series "The Expanse" was seeing the Mormons attempt to go to outer space. Their customized space ship included a temple. 10/10 recommend.
The thing that I liked best about the show is that in many ways, it portrayed a plausible space-faring future. Not everything was bright and shiny, but neither was it a dark vision. It hit a happy medium.
