bathtub swirl
Some years ago I listened to an interview on CBC's "Quirks and Quarks" science show.
Some australian researchers actually conducted this experiment. (now this is all by fuzzy memory and I can't point you at a refrence).
They used a large, circular "tub" (tank actuallly) a couple of meters across.
They went to great lengths and days to allow it to stablize. Now the punch line -- lol --- I can't remember if they saw the effect or not.
However, what I do remember is that you will not see it in a bathtub. The residual 'swirl' is huge compared to the coreolis force and will overwhelm it. It takes extraordinary lengths and a symmetrical tank to give any chance at all of the effect appearing. However there is a force there and it can happen at some scale. You have to be very very careful in how the 'plug' is removed or this will introduce a swirl. This can not, apparently, be controled in a normal bathtub.

Yes another suggestion
The whole big bang thing and cosmology is very hard to get your head around.
It will work ok if you just decide that God kicked the whole universe off about 13.7 billion years ago and leave it at that. After you've dealt with less head hurting things and get some more education in science and math you might want to return to all of this.
Meanwhile, you might want to look into the age of the earth. If you can't accept an earth of 4.5 billion years you are NEVER going to get comfortable with a 13.7 billion year old universe that expanded from a small volume in a way that only the math can properly describe.

The germ theory of disease
And what do you mean by that?
Is that a crack at my education?
I don't know what your education is. I do know what you post. You keep posting howlers.

Milky Way
Thatis the sagitarious arm. It is brightest in the constellation sagitarious and in that direction is the galactic centre.
I used to love laying back on the dock at my parents place with the milkyway over head. I'd often get the feeling of being "tilted" with the earth and I not aligned with it correctly. From up there Andromeda was also visible on dark enough nights.
