no andy, i think the kickback is actually due to the general air of "I can produce an excuse for everything that says 'Humanity knows nothing, so why
Suggesting the HST data is useless in regard to observations of SagA* is obvious but not for the reasons you suggest.
What you suggest is just as short sighted as saying "Lets throw out and burn all of Einstein's books because, you know, its old and hey, we cant prove
some of it so, lets just go back to looking at the stars and sacrificing goats to appease the gods"
So if you knew about the subject you would know that;
1) SagA* is obscured from view in the optical region of the EM spectrum due to dust in the galactic disk,
2) Dust can be 'looked through' using IR, thus the highest spacial resolution observations we have are made are within IR... using this region, the
orbital movements of several stars have been mapped around the central object
3) The region has been observed extensively using the Chandra instrument, an instrument designed to map X-ray emissions... a key observing window for
x-ray sources such as highly compact objects... we know of many black hole candidates from this instrument
4) For higher energy observations there is also the MAGIC array which can search for high energy emission from objects
5) The region has been observed for a long time using Radio telescopes
So i think the total length of time we have been looking at the region with our different eyes into the universe covers around 20 years now (maybe
closer to 15) so once more, to basically say "We know nothing because of x problem" and then not discussing anything to do with that issue, like,
suggesting you might know more about it than thousands of astronomers and physicists is in itself quite arrogant.
There is a hell of a lot we don't know about in this universe... this is true... but scientists strive to discover. SagA* is an interesting object as
it is pretty dang hard to explain what it is, should it not be a black hole... especially when you consider the orbit of the S14 object is of
Which swings around in its orbit, the focus point of which is about 45AU away at its nearest point... all points at an object, of about 2-3 million
solar mass, within less than 45AU, that is producing ZERO visible light.
im not a gambling man, but that kind of sounds like a black hole
