Is there a limit to how big something can be?

Yes, there are limits. In many cases, they are defined by simple forces. One of the major forces is gravity. Some objects can only get so large before they simply deform under ordinary forces.

Is there a limit to how dense an object can get?

Almost all materials will reach their maximum density at very low temperatures and very high pressures. Black holes are the densest known objects in the cosmos and are thought to be infinitely dense; considering infinity means ‘no end’, to answer the question, maybe there are no limits to density!

Does a denser object have more mass?

Density is how tightly (or loosely) packed particles are. The more closely packed particles are, the more dense the object. The amount of mass in a particular space or volume. The more particles (or mass) in a given space, the more dense it is.

What is the most dense thing in the world?

At the modest temperatures and pressures of Earth’s surface, the densest known material is the metallic element osmium, which packs 22 grams into 1 cubic centimetre, or more than 100 grams into a teaspoonful. Even osmium is full of fluff, however, in the form of electron clouds that separate the dense atomic nuclei.

Does dense sink or float?

If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.

What floats in water but sinks in oil?

Alcohol floats on oil and water sinks in oil. Water, alcohol, and oil layer well because of their densities, but also because the oil layer does not dissolve in either liquid.

Is a black hole dense?

A black hole is an extremely dense object in space from which no light can escape.

Does milk float on water?

It depends on the milk. If it is full cream milk 1 liter of milk will be lighter than 1 liter of water, because of the fat content. Skimmed milk, from which the fat portion has been removed by churning out the cream will be heavier than water.

Why does a brick sink in water?

A small, heavy object has higher density than a large light object. The density of the brick with all those bubbles is less than that of water – so the bricks float, no matter how many of them you stick together.
