This structure may work is made in real life. Why, because the spinning of the ring (to keep it in orbit) keeps the upper part of this not fall on the lower part. And the gravidy won't be strong enough to really effect the upper part.
if teh structure is not strong enough its gonna caollapse and kill eveythinmg on it
@NoVicE Q U A N T U M G R A V I T Y isn't understood yet.
@kerponaut, Yeah, but these would be enormous.
I perfectly understand you NoVIcE but of course im not so stupid that i foul make a ring around a star and just think taht i fould stay there... no of course i fould try to keep it balanced whit menuvering thrusters.
@NoVIcE: ugh... what u say? its too hard to understand by me...
, and when you add this effect over trillions or more atoms, electrons, photons etc, the gravity pull will not be uniform, and it will start to unbalance to the extent where it becomes too much and it crushes. But a nice concept though.
Acutally, even a perfect ring round a perfect sphere, centered perfectly, will not stand long enough. Remember that ANY two particles are attracted to each other, the effect of gravity falls drastically over distance, but never reaches zero. And since you cant know the exact position of an electron for example, and it will be in a random position everytime (still around the atom), it will off-balance everything a tiny tiny bit, pulling it some atom from the ring a little bit
