"...this structure had simply passed through the black hole..."

no. not "through" the black hole...maybe through or in the vicinity of the accretion disk which surround the supermassive black hole. the gas cloud likely didn't come close enough to be significantly affected by gravitational tidal effects from the bh.

remember there is no telescope that has a direct line-of-sight view of Sag-A* & the central galactic core region. existing systems pinpoint the location & must still "look" through a thick haze of gases & other various materials.

Who needs or even wants this? Meta is trying to showcase this and no one is listening, Google had their shot a little over 10 years ago, it wasn't just that the tech was not ready, it was just a pointless product with no market.

We're going in circles coming up with gimmicks when the most useful and desired stuff gets ignored by big companies, It's stupid.
