# What are the flaws of oscillating universe theory?

## What are the flaws of oscillating universe theory?

Some difficulties of a perpetually oscillating model, namely, entropy increase, mass increase due to particle production, and increase of metric perturbations (appearance of gravitational waves) in the process of collapse, are considered in the framework of the model.

## What is the meaning of pulsating universe?

The pulsating Universe theory, a variation of the Big Bang theory, in which the Universe goes through successive periods of expansion and contraction. Thus, according to this theory, the Universe pulsates endlessly between the Big Bang and the “Big Squeeze”.

Who proposed pulsating universe theory?

The pulsation theory was first proposed as a possible explanation as early as 1879, was applied to Cepheids in 1914, and was further developed by Arthur Eddington in 1917–18. Eddington found that if stars have roughly the same kind of internal structure, then the period multiplied…

### How is the pulsating Universe related to the Big Bang?

The pulsating Universe theory, a variation of the Big Bang theory, in which the Universe goes through successive periods of expansion and contraction. At the end of the compression stage, when the Universe is concentrated in a small volume of high density, there is probably a” break-up” of the Universe, called an Bang.

### How did Albert Einstein come up with the pulsating universe theory?

The pulsating universe theory, which is more commonly known as the oscillating or cyclic universe theory, posits that the universe goes through regular cycles of expansion and destruction. This theory is credited to Albert Einstein. In the cyclic model, the universe begins with a “big bang” and ends with a “big crunch.”

How is the collapse of the universe solved?

The collapse of the universe into a big crunch results in a loss of entropy. Newer models solve this problem by factoring in dark energy, a type of energy not yet discovered in Einstein’s time. This theory is not the currently accepted theory about the origin and end of the universe, but does explain some shortcomings of other theories.

Which is an unexplained quirk of the Big Bang?

Yet another quirk unexplained by the Big Bang is the Flatness Problem. Almost all the evidence collected by cosmologists indicates that the Universe is flat. Like a sheet of paper on a desk, spacetime shows almost no curvature whatsoever. Within the context of the Big Bang, this seems extremely unlikely. Lastly,…
