Fluffy galaxies do not require dark matter to explain their star rotation with respect to their center even they have empty space at the center. like in the below link. how does this galaxy rotate following general relativity Vs galaxies with a black hole at center...

I mean to say whether fundamental science of gravity still a mystery to be solved?

I came to know Newton's gravitational laws describe gravity as how it works. similarly, Einstein's general theory of relativity describes gravity geometrically. Also, later one passes all the tests. But when I think with fundamental science, I feel that both of above are not correlated with...

I got an idea that Moon/Sun causes solid earth's volume change(by distorting Earth's spherical shape). Is it possible that ocean water volume increases due to gravitational pull by Moon/Sun? Also, due to this eccentric change, Earth's rotation gets unbalanced, So it tries to get balanced by...
