New to this and was thinking about extreme cases to help me get my head around how this all works...need help..
Imagine we have an object with mass moving along. Not that this is possible, but what if all other mass in universe was somehow utilized in some nuclear reaction so ALL energy in...
Basic question I'm sure but...please help...
If there is an object of some mass accelerating toward some other massive object, I can see that total energy of system is same regardless of time as potential energy from gravity well is being lost as kinetic energy of object increases. It would...
Answered my own question after thinking about it...
We need to SEE the planet transit the star, and most times the planet transit won't be in our 'line of sight', so I guess that's the reason...
Sorry if dumb question, but what is the generally agreed reason given for why there are approx. 40 stars closer to Earth than the closest star with a detected planet ?
1)We looked exhaustively at the first 40 and found no evidence of planets ?
2)Is there some property of these closer stars that...
Sorry, I re-read the intro again, and it contained numerous mentions of the 'dedicated geodesy campaign' and a brief explanation, I'll do some research on the precise methods elsewhere, sorry too quick to ask... Disregard last question.

Just read the released PDF regarding results. Thanks. The document contained enough detail for me to understand the methodology of how the timing was accurately 'synched' however details of how the distance between the points is confidently accurate is missing. The paper simply...
Dumb question probably. But how often is the distance between source and destination in this experiment measured ? The Earth is pretty big, is it not possible that it's surface is simply flexing all the time, and that sometimes the distance between the points as a direct through-earth straight...
Given the small (to me it's small) amount measured beyond c, and where speed is just distance / time...
1) How is it they are so certain to the exact distance involved in this experiment ?
2) How did they rule out possibility that with the slight increase in energy density along the path of the...
* But what if...my 2D representation of surrounding mass was viewed slightly differently ?
In my 2D representation of 'surrounding' mass, what if we think of the 2D image like we view a polar map projection. Picture a surface of a sphere where the 2D images of sample mass items I provided are...
Thanks for reply. But your conclusion regarding 'center' of gravity, I think may be mistaken ?
If we assume the mass I was speaking of was large (orders of magnitude greater than the little specks we call galaxies), wouldn't every bit of matter regardless of where it is in our 'observable...
