WebEntropy is a measure of the disorder in a closed system. According to the second law, entropy in a system almost always increases over time — you can do work to create order in a system, but even the work that's put into reordering increases disorder as a byproduct — usually in the form of heat. Because the measure of entropy is based on ...

A closed universe is said to have positive... The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach zero, an event potentially followed by a reformation of the universe starting with another Big Bang. The vast majority of evidence indicates that this hypothesis is not correct. Instead, astronomical observations show that the expansion of the universe is accelerating rather …

Explanation: Scientists have calculated the "critical density" of the universe. Critical density is proportional to the square of the Hubble constant, which is used to measure the rate of expansion of the universe. Comparing critical density to current density can help scientists understand the cosmos.

WebOct 24, 2024 · The theory, as developed by a Greek atomist, states that the universe is made up of atoms, which collide and interact with each other to create different phenomena. According to this view, “the world is likened to a large clock, which is created and set into motion by a powerful god” (Nakayama 78).

Global structure covers the geometry and the topology of the whole universe—both the observable universe and beyond. While the local geometry does not determine the global geometry completely, it does limit the possibilities, particularly a geometry of a constant curvature. The universe is often taken to be a geodesic manifold, free of topological defects; relaxing either of these complicates the analysis considerably.
