Waiting for answer How is buoyant force related to floating and sinking?
If the buoyant force on an object exceeds the object's weight, it will float. If the weight of the object exceeds the buoyancy force, the object will sink. If the two forces (weight and buoyant force) are equal to each other, the object is said to be neutrally buoyant. This occurs when the object...

Waiting for answer How does Hubble's Law resolve Olbers Paradox?
Hubble's Law shows that the more distant a galaxy higher is its redshift. So the visible light from galaxies that are too far away would be redshifted to invisible wavelengths. So stars beyond a certain depth of space would go invisible resolving the Olber's Paradox ....
