Stacking two polarizers, and rotating one, should at a certain angle lead to no light getting through, black, dark, nothing. Not so with this one, it’s very weak in this regard. This might be fine for landscape photography, but in many applications a very strong elimination of reflections is desired. If this filter is weak, why don’t they say so in the tech specs?
Help answer the question about Center Spot
If Earth had a hollow spot at the exact center, you were in the hollow spot, would you experience gravity?
What direction would you be pulled since you would have a balanced pull from all directions ... ie half the mass of the Earth in all directions?Given ... Center Spot earth is hot at center... assume it is not...Right now all the mass of the earth is pulling me down and I am not crushed... It seems people can't get passed the idea of creating a theoretical bubble at the exact center... just get passed it and consider it to be possible and think about the other forces happening besides millions of tons crushing down. Lets say you could create the space... in a 71 degree quite comfortable atmosphere... now, would I just float because of the balanced gravitational pull?
